摘要：Automation technology have provided us with various systems that reduces the time and human error.Vehicles, particularly four wheelers are very difficult to drive in the reverse direction. As personally one is very carefulabout, otherwise damage being caused to the vehicle. In view of this to provide a proper guidance to the vehicle inreverse direction, means are provided. Presently the vehicle has alarm system for maintaining the safe distance betweenvehicle and object while moving in reverse direction. When the vehicle gets too close to the object, the alarm istriggered this warns the driver about an object. But this feature has many problems and is prone to human error. Wehave enhanced the facility by using automatic braking when an obstacle is close by. Therefore, in this paperwe propose an “Automatic Reverse Braking system” to prevent collision by using sensors to detect obstacles. The“Automatic Reverse Braking system” will process the sensor data and control the vehicle to prevent accidents causedby careless driving or difficulty in detecting objects in reverse path. In this controlling logic is implemented on FPGAusing Xilinx software. The system designed by VHDL keeps a distance between the object and vehicle to preventaccidents.
