Abstract: Rear-end collision is the most common type of vehicle accidents in which front of vehicle crashes into the rear of another vehicle. Increasing number of vehicles has promoted, lot such accidents in recent years. Although lot of driver assistance systems are developed which includes automatic breaking, rear-end collisions cannot be completely avoided. This paper aims to provide information about a new concept of automatic breaking in which the system uses ultrasonic distance sensor to detect the distance between the car and the vehicle in front of it, and in proportion to the distance between two it applies the brakes. The distance from which the system starts applying the brake is a pre-set value equal to the car’s stopping distance. The sensor continuously detects the road and when a vehicle or obstacle comes in the range equal to the stopping distance of car, it starts applying the brakes so that the car comes to rest position before it hits another vehicle or obstacle. As distance between the two keeps on reducing the intensity of braking increases and when the distance between them increases, the system releases the brakes and accelerates the vehicle again.
