Implementation of FPGA for Automatic Reverse Braking System

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 careful about, otherwise damage being caused to the vehicle. In view of this to provide a proper guidance to the vehicle in reverse direction, means are provided. Presently the vehicle has alarm system for maintaining the safe distance between vehicle and object while moving in reverse direction. 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 enhanced the facility by using automatic braking when an obstacle is close by. Therefore, in this paper we 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 caused by careless driving or difficulty in detecting objects in reverse path. In this controlling logic is implemented on FPGA using Xilinx software. The system designed by VHDL keeps a distance between the object and vehicle to prevent accidents.
