ACCIDENT PREVENTION BY OBSTACLE DETECTION AND SPEED CONTROL OF VEHICLES

ACCIDENT PREVENTION BY OBSTACLE DETECTION AND SPEED CONTROL OF VEHICLES

This project is concerned with prevention of road accidents by obstacle detection and speed control of vehicles. Accidents can be minimized by maintaining a specific distance between the vehicles. The IR sensor, which is attached to the moving vehicle, which detects any obstacles or vehicles which appear within the preset distance. The output of the sensor is used to activate a relay. On activating the relay, automatic speed control programming is performed by the microprocessor and manual operation is performed otherwise. A stepper motor interfaced with the microprocessor effects the change of gear according to the program thereby reducing the speed of the vehicle.
