The Acoustic Parking System (APS) uses ultrasonic sensors installed at the rear as well as at the front of a vehicle to make parking easier. Using information from the sensors, a microprocessor calculates how far is the car from an obstacle. An intermittent warning tone or lights on a display are usually used to give the driver warning of an impending impact with any object caught by the ultrasonic sensors’ sight.
