A Review on Implementation of FPGA for Automatic Reverse Braking System

In this world automation of various systems have been designed just to reduce 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 the same system but we have altered it so that the car brakes are applied automatically when an obstacle is close by. Our aim is to design the Automatic Reverse Braking System using FPGA ( Field Programmable Gate Array) which can avoid the accident in reversing the heavy loaded vehicles like trucks, buses and all the vehicles consisting of braking system. For this purpose we have developed a model which consists of FPGA, obstacle sensors, sensing circuit which serves as the complete mechanism of automated braking system while reversing the vehicles to prevent collision between the vehicle and objects. If there is object in reverse path, the sensor senses the object and the break is applied automatically. In this, FPGA is used as a control unit to which the devices and sensors are interfaced. This system is suitable for commercial vehicles such as car, emergency services vehicles, trucks and buses.
