Abstract
An apparatus for helping a vehicle operator park or otherwise spot a vehicle at a pre-determined vehicle location. The apparatus includes an ultrasonic pulse generator and receiver which sends a succession of ultrasonic sound pulses into a target area and receives echoes reflected from the vehicle and the surrounding environment. A control circuit then determines from these echoes whether the vehicle has reached its pre-determined vehicle spot. If it has, then at least one alarm is sounded to alert the operator to this fact and allow the vehicle to be brought to a halt.
