IOSR Journal of Electronics and Communication Engineering, 2014

Every year, we find more and more road accidents due to increased traffic on the roads, and if you see the statistics, you will find that the causalities are more every year than that of 1970 Indo-Pak war. Experts say, increased motorist population, long working hours and stressful life are the major reasons for the rise in road accidents. The factors are beyond one's control, but if we could alert the driver on the highway, could save many precious lives. We haven't presented a very complex solution for this; neither claimed to be expert traffic controllers. Usually fixing some sort of transmitter system on the highways which can detect the speed of the vehicle and convey to the driver that he is not in the permitted speed limit in a particular area is quite common and expensive. As a simple solution, we have pre installed low cost transmitters on required locations to convey the speed limit information, even further, if the automatic breaking system could be actuated on over speed is a decent approach. We have designed and developed a prototype system of a transmitter and receiver modules. Receiver(s) is (are) kept in the vehicle(s) and transmitter(s) are set up on the road side. As it is a prototype, we have not used any speed sensing devices, instead four switches are used as alternative. The four switches represents or assumes various speed limits say limit 80 switch, limit40 switch, limit20 switch and no horn area. Whenever these switches are pressed, they will transmit the corresponding alert message to the driver so that the driver can handle the situation sensibly. Receiver section has a 2x16 LCD, which will display the alert message, and there exists microcontroller to receive the data and activate the relay circuitry to give a buzzer and to control the speed of the dc motor which acts as a prototype for automatic braking and vehicle speed reduction mechanism.

The braking machine was once designed and utilized on a auto to structure the riding technique protection the use of embedded machine design. Most of the accident happens due to the extend of the riding pressure to hit the brake, so in the course of this venture work braking gadget is developed detailed when it is energetic it can observe brake relying upon the component sensed by way of the ultrasonic sensor and velocity of car. Currently, cars are regularly outfitted with lively protection structures to reduce lower back the opportunity of accidents, many of which appear inside the city environments. The primary famous encompass Antilock Braking Systems (ABS), Traction Control and Stability Control. Of these structures hire differing types of sensors to continuously display the stipulations of the vehicle, and reply in an emergency situation. An sensible braking device includes an ultrasonic wave emitter furnished on the the front aspect of a car. A receiver is moreover positioned on the the front component of the automobile and getting a reflective ultrasonic signal. The mirrored wave (detected pulse) offers the hole between the issues and additionally the automobile and RPM counter offers velocity of car. The microcontroller is functioning to control the braking of the car supported the detection pulse statistics to push the foot lever and observe brake to the automobile remarkably for security purpose

Braking process of a vehicle is complex, giving possibility to the driver to reduce car’s speed or to stop it at big speed in a short distance. Using the diagrams registered for the different working conditions, defined accordingly with the experimental plan, there have been analyzed the values of deceleration, variation of speed and the covered space for each specified moment of braking. As result of the experimental researches, we have reached the conclusion that a good behavior at cars braking is registered when the diagrams of deceleration variation in relation with braking time have a symmetric shape.

The work presents an ultrasonic automatic braking system for forward collision avoidance with accelerator pedal disengagement mechanism. This system consists of ultrasonic sensors namely ultrasonic wave emitter and ultrasonic wave receiver. The ultrasonic wave emitter is provided in front portion of the car, producing and emitting ultrasonic waves in a predetermined distance in front of the car. Ultrasonic wave receiver is also provided in front portion of the car, receiving the reflected ultrasonic wave signal from the obstacle. The reflected wave (detection pulse) is measured to get the distance between vehicle and the obstacle. Then PIC microcontroller is used to control the servo motor based on detection pulse information, and the servo motor in turn automatically controls the braking of the car. The present work demonstrates the possible use of an accelerator pedal disengagement mechanism in this system, by which the accelerator pedal is automatically disengaged once the brakin...

In this world mechatronics and automation of various systems have been developed just to reduce the time and human error. The automated braking system is a part of mechatronics. Presently the vehicle has alarm system for maintaining the safe distance between moving vehicle. When the vehicle gets too close to the object, the alarm is triggered this warns the driver about an object. But this feature has many problems and is prone to human error. We have developed a model,by using the same sensor system but with the automated breaking pneumatic system which restricts the backward motion of the vehicle. Our aim is to design the system which can avoid the accident in reversing the heavy loaded vehicles like trucks, buses and all the vehicles consisting of pneumatic braking system. For this purpose we have developed a model which consists of pneumatic cylinder, solenoid valve, IR sensors, control unit etc. which serves as the complete mechanism of automated braking system while reversing the vehicles.

Currently, vehicles are often equipped with active safety systems to reduce the risk of accidents, many of which occur in the urban environments. The most popular include Antilock Braking Systems (ABS), Traction Control and Stability Control. All these systems employ different types of sensors to constantly monitor the conditions of the vehicle, and respond in an emergency situation. In this paper the use of ultrasonic sensors in safety systems for controlling the speed of a vehicle is proposed. An intelligent mechatronic system includes an ultrasonic wave emitter provided on the front portion of a car producing and emitting ultrasonic waves frontward in a predetermined distance. An ultrasonic receiver is also placed on the front portion of the car operatively receiving a reflective ultrasonic wave signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle. Then a microcontroller is used to control the speed of the vehicle based on the detection pulse information to push the brake pedal and apply brake to the car stupendously for safety purpose.

This project Implements’ an intelligent microcontroller based Crash evasion system that will employ obstacle detection and distance measurement using ultrasonic sensors to detect obstacles and their distances. Once the obstacle has been detected and safe separation distance is not provided, the automobile will perform safety braking and further decrease in separation distance will cause the system to initiate teering control so as to reduce the severity of the collision. A warning signal is provided to the driver to alert them before he system takes automobile steering into control. Hazard lights are turned ON the moment a collision is detected and rake lights are turned ON after activation of the brake assist system and the brakes which are preferably ABS. Dash board displays of LEDs are incorporated to make the system more nteractive. The system provides for manual control by the driver when they find need to operate the automobile without it as in case of parking and testing or driving in arrow confined paths.

The most frequent cause of vehicle accidents (car, bike, truck, etc.) is the unexpected existence of barriers while driving. An automated braking system will assist and minimize such collisions and save the driver and other people’s lives and have a substantial influence on driver safety and comfort. An autonomous braking system is a complicated mechatronic system that incorporates a front-mounted ultrasonic wave emitter capable of creating and transmitting ultrasonic waves. In addition, a front-mounted ultrasonic receiver is attached to gather ultrasonic wave signals that are reflected. The distance between the impediment and the vehicle is determined by the reflected wave. Then, a microprocessor is utilized to control the vehicle’s speed depending on the detected pulse information, which pushes the brake pedal and applies the vehicle’s brakes extremely hard for safety. For work-energy at surprise condition for velocity 20 km/hr, the braking distance is 17.69 m, and for velocity 50...

Collisions in automobiles have become a major safety concern; cases of damage and death due to automobile collisions are frequently reported. The number of pedestrians knocked to death by automobiles is also on the rise in cities and highways. Further into the game reserves, wild animals are also frequently knocked to death by automobiles. The cost of a life cannot be estimated, the cost of damages to the automobiles also impacts negatively on investment. In most cases drivers fail to notice the presence of obstacles ahead and brakes need a driver's response to operate thus increasing the response time, hence reducing their reliability. Many approaches to automobile crash avoidance systems have been proposed in recent time, however, such approaches mainly concentrate on steering maneuvering control. In addition, these approaches do not take into consideration the safety distance to stoppage of the automobile, more so, many approaches only provide a warning signal to the driver for activating the automatic braking. This always provides a room for human error. This paper presents the development of an automatic microcontroller based crash avoidance system that employs obstacle detection and distance measurement using ultrasonic sensors to detect obstacles and their distances. Once the obstacle has been detected and safe separation distance is reached, the automobile performs safety distance induced braking at that distance to bring the automobile to a stoppage. From the results obtained after tests, the system has an average response time of 0.86s to the activation of the brakes and a 12.8 percentage error with respect to the obstacle real distance.
