System Overview RPAS (Rear Parking Assist System) is an electronic driving aid that warns the driver to be cautious while parking or in low speed environments. The sensor uses ultrasonic waves to detect objects within proximity of the vehicle.
Description To sense the cars exactly in the next lane with the radar, the direction of the sensor and the direction of the vehicle have to align. This is BSD unit alignment. If this alignment is not performed as below illustration, the degradation of detection performance and the cause of false alarms.
