DEVELOPMENT OF BLIND SPOT WARNING SYSTEM FOR VEHICLES BASED ON ULTRASOUND SENSOR & DISPLAY

ABSTRACT

 

Insects can be a serious problem for some people. Harmful disease transmitting by insects such as houseflies and cockroaches are the most terrifying creatures which scared off most of the people with it smells and disgusting look. To deal with those insects and eliminate this insects effectively, the automated Passive Infrared (PIR) motion active type of pest repellent system is proposed. It have a specific microcontroller which control how the system works such as the on and off of the system, the position and the baits or sensor used. The microcontroller control the repellent system by using information gathered from the PIR motion sensors integrated into the system and manipulate the position of the sensor detection.

This project is focus to redesign and fabricate new automated active type pest repellent system by integrating the PIR motion sensor which is able to distinguish all the insects at the same time. This project has successfully designed an automated PIR motion pest repellent system. The design is focus on the motion sensor that were integrated in the system to enhance the reliability in detecting the pest movement. Thus, the active system also have been integrated to the prototype by using Arduino controller as the medium to control the application and sensor that have been installed.

The result shows that the PIR motion sensor can detect the movement and send the output to turn on the application. This also shows that conservation of energy can be achieved by the active system where only 5V of power supply required to triggered the motion sensor and send the signal to relay to get the 240V of application to functioned.

INTRODUCTION

1.1 Background of study

driving an automobile in cutting-edge movement conditions is fantastically unsafe. The high chance should manifest if the motive force viewing the upcoming road risks and in the period in-between, appearance in reverse in expressways riding. it’s far basic to look both sideway and in opposite earlier than securely change the paths. A difficulty that frequently concerned by using the driving force is the ranges cannot be visible by way of aspect view and returned view mirrors, that’s called as blind spot vicinity of car. In some mischances instances, it’s miles passed off because of a driving force’s failure to display the blind sides district properly. As per a review from 1995, The discoveries show that the greater part of path change moves happen on level ground, straight street, dry street conditions and great climate amid the daytime or in lit evening time conditions (Varghese et al.,2014). These elements ought to support the utilization of mirrors and direct visual perception seeing by the driver. the realization is that mirrors and physically turning the top and frame alone aren’t furnishing the driver with adequate information to keep a strategic distance from a mishap (Lin and Li,2010), Blind spot district is a selection to the side and marginally at the back of driver fields of imaginative and prescient that is not reflected within the vehicle improve replicate and requires the driver to turn their make a beeline for display screen the area earlier than making any interest, as an instance, converting the path. An problem might be takes place whilst a vehicle shifting in the direction of every other automobile blind aspect and the driver now not capable of see the vehicle pick out to exchange the course. for example, allude photograph in figure 1.1 below, place of motors out and approximately and the driver’s view from facet reflect and returned reflect become regarded. At the correct facet, the blue car is in the green car blind side region and drivers can see a tad bit some portion of the blue automobile and anticipate the place of the auto is a long approaches in the back of from his automobile. At that point, when the inexperienced car chooses to alternate the direction, mischance may additionally manifest. what’s greater, several road mishaps are takes place in blind facet district particularly in thruway due to surpassing, being weigh down or converting the course activity. Now and then, a few drivers are excessively centering, making it impossible to screen their blind aspect locale and misfortune listen out and approximately earlier than them. those sports may additionally lead them into mishaps that make a contribution into harm, misfortune or even passing. The outcome of the mischance will bring difficulty to any consisting of birthday celebration. Mindfulness from the issue, several devices had been designed to display screen the locale, as an instance, blind side mirror but it much less viable as mischance nevertheless happens in mild of the fact that the system exactness is relies on upon the driver. on this way, a framework that can perceive cars nearness in blind side and cautioning the motive force had been designed to assure the street client wellbeing.

Figure 1.1 : Example of Blind Spot

1.2 Problem Statement

 

these days, innovation in automobiles has been speedy increasing to diminish the threat of twist of fate even as driving automobile. there are numerous research proposed in view of the using help framework concentrating at the blind spot district (Ollis et al. , 1999).

Blind spot is ranges around a car that can’t be watched mainly by using the driving force, in this manner numerous avenue accidents occur in mild of the motive force not able to see some other motors method the blind spot particularly even as converting the lane. Then, to conquer this hassle a system that could locate the motors within the blind spot stages need to be fabricated to alert the driving force approximately the case at the blind spot ranges to assure the safety of road customers. In figure 1.2, the vicinity approximately generally called to blind spot is the returned quarter blind spots, area towards the lower back of the automobile on both facets. motors inside the adjacent ways of the street may additionally fall into those blind side, and a driving force can be no longer capable see abutting vehicles the usage of handiest the automobiles mirrors. specific zones which are periodically known as blind spots are those that are too low to look behind and before cars. additionally, in occasions in which side vision is deter zones to one facet or right can emerge as it appears that evidently blind facets too.

LITERATURE REVIEW

2.1 Background

Literature review was done all through the entire project to pick up learning and enhance aptitudes expected to finish this project. The principle hotspots for this project are past related activities, inquire about postulation, books, diaries and articles which are generally gotten from online databases. This part concentrates on the essential ideas and all central speculations which identified with this project.

2.2 Blind Spot

 

The blind side of vehicle the street region that is undetectable to the driver View factor while looking through aspect-view or lower back view mirror (Yu et al.,2013) without head rotation (Anon ,2014) which can lead into mishap. The spot will become maximum vital while the driver is converting route. as an example, a driver who will switch to another lane seems inside the facet mirror to affirm that the path is loose, however an automobile suddenly comes from in the back of, exactly when the driving force goes to move to any other lane (Yu et al.,2013), hence accident could be occur if the driver push aside the blind spot reigns. except in Australia, there are massive variant and growing gap between bicycle owner and car occupant protection upward thrust by biking blind spot (Anon,2014) . as a result, blind spot can increase the threat of accident.

2-3  Steps of BSD System

2.3.1 convex  mirrors

Utilize a blind spot mirror. These are little, curved mirrors that append to either your driver’s side view mirror or its lodging. The mirror is bended outward, which offers altogether better perceivability and can help upgrade your security. The mounting area for a blind spot mirror is by and large at the upper external corner of your side view reflect, yet this changes starting with one car then onto the next. You’ll have to explore different avenues regarding distinctive areas to locate the one most appropriate for you  ( Valerie Johnston , 2015) .

 

figure 2.1 shows the Different installation of the convex mirror on each vehicle

2.3.2 Side Eye: Mobile Assistant for Blind Spot Monitoring

As per the activity safety facts report of National Highway Traffic Safety Administration, more than five million police-revealed motor vehicle crashes happened in the United States in 2011(NHTSA,2013) . Diverted driving is an always developing concern and driver wellbeing frameworks are progressively getting embraced. Be that as it may, despite everything they stay as elements in the extravagance vehicles. The high entrance of cell phones has made it conceivable to bring some of those wellbeing highlights inside everybody’s scope. While a portion of the current works have proposed following the street conditions and observing the driver with a cell phone, they have not secured the blind spot. In this paper, we exhibit Side Eye, a cell phone based framework to screen the blind spot on the driver side and caution the driver about the nearness of a vehicle . We investigate two methodologies in view of force variety and shape coordinating to recognize a vehicle in the blind spot . Our assessment demonstrates that, when a vehicle is in the blind spot, our framework can distinguish and caution the driver with a precision of 87% progressively(Singh et al.,2014).

2.3.2.1: Area to Monitor and Alert

Fig. 1 demonstrates a case of how we mount the cell phone in the vehicle. We can without much of a stretch discover a place to mount the cell phone on the windshield or on the dashboard to permit the front camera of the cell phone to screen the blind side range. The red polygon appeared morally justified of Figure 2.2 is the region of interest (ROI) on which our Side-eye framework will screen, which covers the blind side of the driver. The ROI is the region on the following path on the driver side. At the point when there is a vehicle in ROI, it is anything but difficult to bring about crash if the sense of self vehicle endeavors to change path without seeing that vehicle.

The cell phone’s screen is confronting the driver. At whatever point Side Eye identifies a vehicle in the ROI, it cautions the driver at the earliest opportunity to enhance security. The framework can function as a daemon string all the while with different applications in cell phone, e.g. route application. Just when the framework distinguishes something basic, i.e. a vehicle is in the ROI, it alarms the driver. The framework could caution the driver in various routes, for instance, demonstrate a notice symbol on the screen or give a sound cautioning.

 

 

2.3.2.2: Schemes

We utilize camera to screen the ROI and process the data in the video outline. Actually, we utilize PC vision based methods to carry out this occupation. We investigate two ways to deal with distinguish whether there is a vehicle in the ROI (Reviewed et al.,2006). One checks for the adjustment in the power of picture inside ROI; alternate searches for the vehicle in ROI by the information of vehicle’s shape. Underneath, we show the force and form coordinating based plans for distinguishing vehicles. 1) Intensity based plan: When there is a vehicle in the ROI (as appeared in the upper right of Figure 2.3), the appropriation of the pixel force of the ROI could be essentially not the same as the situation when the street is void (Figure 2.3(top left)).

In this research we show Side Eye, a cell phone based application which screens the driver-side blind side and alarms the driver. We assessed our framework on information gathered from a regular roadway driving, and furthermore measured the proficiency on a genuine cell phone. The outcome clarifies that it is conceivable to adequately identify and alarm the driver when there is vehicle in the blind side region. Our framework can accomplish accuracy and review both at around 85% in distinguishing the scene in the blind side region. Albeit Side Eye needs facilitate refinement to make it vigorous, it indicates guarantee in enhancing the driver wellbeing. On the off chance that done well, Side Eye can fill yet another wellbeing highlight ailing in non-extravagance vehicles by conveying it to the universal cell phones.

2.3.3 Blind spot detection system of Volvo vehicle

From Figure 2.4, another case of usage of blind spot checking framework. The Volvo vehicle utilize in light of radar detecting that advises the driver about vehicles in the blind spots on both sides of the car. It is additionally identify and cautions the driver to quickly moving toward vehicles up to 70 meter behind the car (Anon,2014).

2.3.4 Blind spot detection system of BMW (5 series):

Blind spot discovery framework is system that actually fundamental to display screen blind side district at the same time as riding car in current motion situation. effect among car can often manifest if the driver did no longer legitimately nicely check the blind
aspect locale amid changing the path.

Figure 2.5 Blind spot monitor

The encompassing range of the driver and the condition ebb and flow of circumstance for potential risk should be considered as driver need to change the paths.

Situation awareness (SA) in the observation and acknowledgment stages is critical when a man has time close by, for example, while moving to another lane. SA can be characterized into three levels(Endsley,1995)
level 1: Perception of components in the earth
level 2: Comprehension of current circumstance
level 3: Projection of future status
Thus, around 75% of the mischance amid path changes is because of driver Situation Awareness disappointment (Knipling,1993). Blind side observing framework is basic to enhance perceivability and lessen the visually impaired zone keeping in mind the end goal to actualize wellbeing driving.
These days, blind side observing framework is executed in a few vehicles. Ordinarily, top of the line and cutting edge vehicle utilizing installed arrangement of blind side checking. In the meantime, low-end vehicle requires driving help of blind side observing framework. Either installed framework or driving help the point is just a single to enhance security while driving a vehicle. For instance, BMW (5series) display have the dynamic blind side discovery to ready driver if there any up and coming potential danger in blind side zone.
From figure 2.6, dynamic blind spot discovery arrangement of BMW (5series) show help to take out blind facets and without a doubt allows drivers to stay away from influences even as switching to any other lane, certainly retaining your look directly beforehand. utilizing radar detecting to distinguish substance vehicle and set behind the vehicle. This framework cautions drivers if a vehicle is in their blind side locale car. The light show on their side-see reflect lodgings starts to streak and furthermore controlling wheel vibrate.

2.3.5 Blind-Spot Camera System

 

side mirror mounted electronic visual assist system for enhanced driver awareness The left side outside mirror gives ~5° view to the driver, and the correct side just ~12° see, while the inside rearview reflect gives ~20° see, leaving almost 37° of the back view region darkened from the drivers see – an expansive blind spot ! Path moving without some extra view can undoubtedly bring about a mishap if a passing vehicle is darkened inside that visually impaired zone to either side. Blind spot cameras essentially increment the obvious range left and right, improving driver familiarity with space adjacent to them by for all intents and purposes taking out the blind spot . Blind spot cameras give a 120° wide edge see. Multi-pivot customizability makes for adjustment to an extensive variety of mirror unit shapes. Associates with ANY trigger wire or video flag initiated video show with RCA input. Turn signals initiate cameras (Anon,2014).

2.4 A Wireless Sensor-Based Driving Assistant for Automobiles in view of ultrasonic detecting.

on this paper, the framework is going about as a driving assistant for cars that acknowledges the difficulty or protest in the observed area and alarm the driver via cloth, sound and visible flag. This using right hand relies upon on ultrasonic detecting technique (Anon , 2014).

The framework includes 5 separate components: four of them are the sensor modules and the fifth one is the controller. The hubs are associated inside the continuation that joined to body of the automobile. inside the suggest time, controller in charge of making plans the operation of the hubs and after that process the data for introducing alarms to the driving force. the two front corners on each facets of the vehicle are secured with the aid of sensor modules. even as the blind spot regions are the probably ones to be dismissed by drivers, the 2 front corners are determined to create the most astounding mischance fees (Anon,2014) (Yu et al. n.d.,2013) . As appeared in determine 2.10, it demonstrates the connection some of the framework elements. each one of the 5 modules are makes round a similar preparing unit comprising of a microcontroller and radio handset. The sensor modules comprise of ultrasonic sensors in a similar time the controller related to 3 styles of markers, as an instance, LEDs board, bell, and the vibrators mounted on the directing wheel (Academy et al. , 2009) .

 

(adjusted from: http://www.suurland.com/blueprints_archive.php)

Identified with this exploration, there are four essential parts should be considered. There are sensor, marker, remote correspondence and modules. The using colleague distinguish the protest or obstruction through ultrasonic nearness sensor (PING))) TM Ultrasonic Sensor, Parallax Inc). every other option for discovery the protest is by infrared sensor yet infrared sensors do no longer have the exactness in their ultrasonic partners because of the encompassing commotion and infrared radiation (Anon,2014) .

As in line with table 2.1, the pointer can be sensible and cautions the driver if query input the blind spot district region. vehicle is ordered safe and the every one of the hints deactivated if there aren’t any obstructions or question are to be had in region 1 and eleven area 2. within the intervening time, LED suggestions are swung directly to give warning to driving force if the gadgets enter in sector 1 and will be considered as “extremely debilitated”. for this reason, while question enter region 2, the car is ordered “undermined”. driven markers, either the vibrators or the bell are turned on (Anon , 2014) .

The wireless communication is related between the sensor and the ultrasonic sensor. Favorable function of utilizing remote association is the easy established order. It moreover did now not require greater space for wiring the blind spot discovery framework.

2.5 Ultrasonic sensor based blind spot mishap avoidance framework

In this exploration paper, the framework in light of nearness identification gadget is utilizing radio recurrence waves for recognizing object. It incorporates three parts(Academy et al. , 2009) :

2.5.1 Front sensor, left sensor and right sensor

The front sensor is practical to recognize normal dark spots. This sensor will display nearness of any substance and caution the motive force approximately the up and coming chance in instances of transitory blind spot . In figure 2.11, it demonstrates the placement of sensor append on frame of the automobile. The left and proper sensor will cover the blind spot at again of car.

 

 

 

 

 

 

 

 

 

 

 

2.5.2 LED meter

As regarded in figure 2.12, the LED meter practical in mild of the sensor to warning the driver approximately element query or doable hazard. The LED meter changed into partitioned into 3 section actuation. at the off chance that the left sensor distinguish the protest the left hand aspect LED meter will be actuated. while, if proper sensor distinguish the question the proper hand aspect LED meter may be activated. eventually, the front hand side LED meter reveal threat of the front sensor.

2.6 Some components that used in applications of blind spot: –

 

2.6.1   Microcontroller:

A microcontroller is a bit pc on a solitary coordinated circuit containing a processor middle, memory, and programmable input/output peripherals which can be supposed for inserted programs, in preference to the chip utilized as a part of desktops or different universally useful packages. by means of lessening the size and cost contrasted with a plan that makes use of a specific chip, memory, and enter/output devices, microcontrollers make it sparing to carefully manipulate notably extra devices and techniques.

Figure 2.13 : The microcontroller 16F877A

2.6.2 PIC

PIC or Peripheral Interface Controller is a group of microcontroller adjusted using Harvard engineering which bodily isolate ability and flag pathways for instructions and data by using Microchip era. snap shots are widely known with both current designers and experts alike because of their minimum attempt, huge accessibility, significant patron base, extensive accumulation of utilization notes, accessibility of ease or unfastened development gadgets, and serial programming (and re-programming with flash memory) ability. The blessings of percent is, little route set to research, RISC

(Lessened training Set Computing) layout, labored in oscillator and in circuit troubleshooting, PICkit is available.

The PIC16F877A segments is 256 bytes of EEPROM records reminiscence, self-programming, an ICD, 2 Comparators, eight channels of 10-bit Analog-to-digital (A/D) converter, 2 catch/look at/PWM capacities, the synchronous serial port can be planned as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Joined Circuit (I²C™) delivery and a familiar Asynchronous Receiver Transmitter (USART). those elements make it ideal for greater pushed stage A/D applications in car, present day, mechanical assemblies and client packages.

                                        Figure 2.15 : PIC 16F877A

 

 

 

2.6.4 Sensor’s

 

on this project, sensor is utilized to recognize an automobile nearness in the blind spot range to manufacture automatic gazing framework, in this manner the sensor has to be chosen shrewdly in light of the truth that each sensor has theirs expert and cons. as an instance, imaginative and prescient based sensor may be applied to watch the blind spot efficaciously but under first rate weather or ecological difficulty, as an instance, murkiness, the sensor cannot be utilized extremely properly. other than that, for radar or Radio Detection and varying has least false warning gadget, which sounds the warning simply when there was a relative development between the automobile and the protest (Indoware 2013) . moreover, this sort of sensor cannot apprehend query of converting size what is greater, role. whilst laser sensor discharge a thin light emission that may be applied to measured separation as much as 100cm accuracy yet may be very high-priced and may be applied as it had been to discover protest inside a solitary plane (Indoware,2013).

On other hand, in view of studies paper accomplished by Tarek Mohammad are speaking about making use of Infrared and Ultrasonic sensor for separation estimation. The paper expresses that Infrared sensor (IR) is much less luxurious in fee and speedier as a result time of than ultrasonic sensor (US) (Measuring and Unit,2006) . apart from that, IR sensor is utilizing pondered mild and depends reflectance of surfaces homes while US sensor is making use of taken into consideration waves which self-sustaining reflectance of surfaces residences to gauges the separation from a question (Measuring and Unit,2006). At that point, the author looked at both sensors using Phong Enlightenment model approach to determine their reflectance properties of the surfaces and figuring of a separation. From the outcome, the sufficiency of us sensor is reliant at the separation and advent of the obstacles loved ones to the sensor and the yield flag is free at the surfaces shading and smoothness. even as, for the sufficiency of IR sensor is concern to the reflectivity of the protest obstruction and marginally reliant on ecological situation, for instance, daylight hours. On another palms, US sensor has particularly higher determination than IR sensor specially for little separation estimation inside theirs usable variety (Measuring and Unit , 2006) . therefore, US sensor is advanced to IR sensor for outdoor application.

Ultrasound sensor

    Figure 2.16: Comparison between IR sensor & Ultrasound sensor

2.6.5  Ultrasound sensor

Ultrasound sensor can be use as item finder effects, for instance the case examine accomplished by means of L.S Guo, system protection Detecting system with Ultrasound Sensor for Agricultural machine is examining approximately how to apply US sensor to identify the placement of the transferring articles round agrarian machines and produce a be aware framework whilst a protest is distinguished at close separation with the system (Indoware,2013). The framework is making use of 2 settled US sensors to pick out any nearness across the transferring article (Indoware,2013) .what is extra, in mild of research done by Johann Borenstein and Yoram Koren, ultrasound sensor is the satisfactory choice to use for obstruction evasion for flexible robot (Indoware,2013).

except, the thing via Alessio Carullo and Marco Parvis, A Ultrasound Sensor for Distance measurement in automobile programs is talking about on how US sensors have been linked in a savvy for the separation estimation within the scope of few centimeter to the few meter . apart from that, in this paper the author depicts an ease US separate meter that performs contactless estimation of the range starting from the earliest stage an automobile body. The separation estimation, D may be gotten using situation beneath(Indoware,2013):

D=k  . Tf  . Vs

Where,

k = constant close to 0.5, depends on the sensor geometry

Tf = time of flight of an ultrasound

Vs = velocity of sound in the air

The separation was measure at distinction temperature to demonstrate the capacity of US sensor to self –adapt to the diverse ecological conditions (Indoware,2013) .The sensor contains a commotion estimation framework and auto-change office of the flag that is utilized to drive the transmitter in this way, creating the best exactness under various conditions.

More or less, US sensor is a superior sensor to be utilized for outside separation estimation or protest recognition on account of its wide pillar width properties and high determination for separation estimation. Other than that, from above research, US sensor can identify a moving toward protest which can be connected in the Blind Spot Detection System. Moreover, the normal for US sensor that can self –adapt to distinction condition will guarantee the Blind Spot Detection System can utilize notwithstanding amid in brutal climate.

MB1010 LV-MaxSonar®-EZ1™ is an end result of ultrasonic sensor produce by way of Maxbotix Inc is something but difficult to interface with others element or framework as the sensor has 3 diverse yield stick which is simple stick, beat width stick, transmission potential stick, transmit stick and collector stick. aside from that, the sensor has 0 no guy’s lands as the sensor can gauge protest put off from 0 – 6.25m, stable range readings, little length and low strength requests. in this manner, the sensor may be catalyst with the aid of battery alongside the whole circuit and consume just a little area. eventually, the sensor is suitable to be utilized for vehicle driver Assisted For Blind Spot Detection device.

2.7 The innovation thoughts of BSD framework

 

The fundamental reason for development thoughts of BSD framework is to comprehend strategy utilized as a part of past research of blind side checking framework before applying to this project. There are a few thoughts of innovation that identified with blind spot data framework:

2. 8 The idea of ultrasonic sensor

Ultrasonic signs resemble capable of being heard sound waves, aside from the frequencies are considerably higher. The ultrasonic transducers have piezoelectric precious stones which reverberate to a favored recurrence and change over electric vitality into acoustic vitality and the other way around (Terzic,2013).

The outline in figure 2.17 shows how solid waves, transmitted within the nation of a cone, are meditated from an objective back to the transducer. A yield flag is created to play out some kind of demonstrating or control work. A base separation from the sensor is needed to offer a period postpone in order that the “echoes” may be deciphered. factors which could affect the operation of ultrasonic detecting consist of: goal surface point, sensible floor unpleasantness or changes in temperature or stickiness. The objective will have any type of intelligent shape – even spherical articles.

 

 

 

2.9 Advantages of ultrasonic detecting contrast with another framework detecting in BSD framework.

A few framework detecting can be connected for observing blind spot district. For instance, there are three sorts of sensor frameworks installed vehicle for horizontal object location (Terzic,2013) :

I. Ultrasonic sensor framework

II. Doppler radar framework

III. Vision framework

The ultrasonic strategy has exceptional points of interest over regular sensors, for example, infrared or turn around sensor when utilized for detecting capacities (Larson,1960) :

1. Discrete separations to moving articles can be identified and measured.

2. Less influenced by target materials and surfaces, and not influenced by shading. Strong state units have for all intents and purposes boundless, upkeep free life. Have capacity to recognize little protests over long working separations.

3. Have imperviousness to outside aggravations, for example, vibration, infrared radiation, surrounding clamor, and EMI radiation

As revealed by ultrasonic sensor framework offers the accompanying focal points:

1. It is more affordable and will be appropriate for general vehicle applications.

2. It can undoubtedly get remove data quick questions without

complex calculation discovery.

3. It has extensive surface estimation, not just single point For the Doppler radar systems, the gadget protected excessive collecting price and obliged for exceptional vehicles in a way of speaking (Anon , 2014) . Radar device is customarily has blind spots and a greater diminutive view. The volume of blind sides relies upon on upon the quantity of the presented radars. furthermore, due to the compelled region evacuate for radar shape, it is tough for radars to understand a dissent moving in a huge range (Indoware,2013) .

Moreover, radar sensor is muddled to utilize, because of the need of CPU-concentrated picture preparing techniques. Likewise, the high of project cost require a more mind boggling preparing stage, which would likewise build the cost of their encasing sensor modules (Indoware , 2013) .

In the vision framework, there are a few issues should be considered. The cost included much calculation time to remove helpful data. Real-time performance is a test issue for vision-based frameworks. Around evening time, it is hard to utilize due to lighting condition will likewise impact the picture procurement

(Indoware , 2013) .

In view of those 3 frameworks sensor, the ultrasonic sensor is preferred rather over making use of Doppler radar framework or vision framework to apply in BSD framework. it’s miles a direct end result of the fee to manufacture this framework detecting is notably less high priced and it may absolutely gather the separation of the protest without complex calculation of reputation method.

 

 

 

2.10  Summary

In conclusion, the literature review has provided the overview of the available Blind spot systems in the market. The characteristics of the entire research has benefited and helped the drivers whose drive vehicles on Hi-way to avoid the risks that occur during cornering toward the right or left of the road, which caused according to the latest Statistics that there are nearly 840,000 blind spot accidents every year. In those crashes, nearly 300 people are killed, most of them in vehicles other than the semi-truck involved. And During the study adopted and applied solutions on vehicles for Ahoudna that there is a gap in the latest methods used to kill the blind in the car (Cameras ) Camera is one of the most successful ways to treat cases of the blind spot, But these systems  can be disrupted by snowfall and rainfall, by snow, ice, dirt present on the camera lenses. Shadows, full light from other cars,  light reflected from wet roadways, and sunlight at sunrise and sunset can cause the systems to produce false – positive alerts. So we suggest a new system to measure the distance between the car that wants to turns and other vehicles on the highway and is used as a sensitive ultrasound with special specifications that can measure any moving objects with extreme precision and the results are displayed on the screen to display the unity of the distances cm / ms with voice say distance. Thus in this way we will be able to kill blind spot when cars work with both camera and sensitive measuring the distance. And thus it can certainly eliminate accidents that occur because of the blind spot.

3. The system can be connected with rear gear so it helps while parking , As shown in Figure 5.18 , 5.19
4. The system can have the ability to switch off the sound warning by the driver.
5. For long range observing separation protest, it is recommended to utilize the XL-MaxSonar-EZL1 Sensor rather than HC-SR04 Ultrasound sensor , As shown in Figure 5.20. The XL-MaxSonar-EZL1 Sensor has many points of interest which are:

• Can identify little objects.
• Small size sensors.
• Maximum scope of distinguishing item is1068cm (420 inches).
• Operating voltage from 3.3v to5.5v.
• Resolution 1cm
• Real time noise dismissal algorithm
• Read from three sensor yields: Analog voltage, Serial and Pulse Width
