Parking and Back-Up Sensor System Description - Components
Parking and Back-Up Sensor Switch
Input to the parking and back-up sensor control unit is performed by operating the parking and back-up sensor switch. The parking and back-up sensor indicator is activated by the parking and back-up sensor control unit.
Parking and Back-Up Sensors
The parking and back-up sensors emit ultrasonic waves, which are reflected by obstacles and then detected by the sensors. The detected ultrasonic waves are converted to digital signals after amplification, and are then transmitted to the parking and back-up sensor control unit. The reference measuring distance is for a circular obstacle with a diameter of 60 mm (2.36 in). The measuring distance will be smaller when the diameter of the obstacle is less than 60 mm (2.36 in).
