Sensors, component description - GF54.65-P-5010GZ
MODEL 164.1/8 with CODE (220) Parktronic system (PTS) up to Model Year 2008
Shown on model designation 164.1
Task
The sensors in the bumpers are transmitters and receivers for the ultrasonic signals necessary for measuring the distance to an obstacle.
Function
When actuated by the PTS control unit (N62), the sensors with an ultrasonic signal. After a short decay time the sensors are ready to receive. Each sensor receives the echo of its own signal and that of the other sensors. The distance to the obstacle is calculated from the elapsed time between transmission and reception.
