GF54.65-P-5013RC PTS Ultrasonic Sensor, Component Description
- with CODE (220) PARKTRONIC

Component Identification:

Location
The front PTS ultrasonic sensors are located on the front bumper and the rear PTS ultrasonic sensors are located on the rear bumper.

Task
The PTS ultrasonic sensors record the distance of the vehicle to an obstacle. The data from the PTS ultrasonic sensors is read in by the PTS control unit (N62).

Function
The PTS ultrasonic sensor actuated by the PTS control unit sends out an ultrasonic signal and is ready-to-receive after a brief "dead time" (time for settling down of diaphragm).

From the "dead time" caused by technical reasons of each PTS ultrasonic sensor arises the lower limit of the monitoring range. Each PTS ultrasonic sensor receives the echos of its own ultrasonic signals and the echos of ultrasonic signals from adjacent PTS ultrasonic sensors. The distance of the vehicle to the obstacle is calculated from the transit times of the echos. The recording ranges of the PTS ultrasonic sensors are a lobar design with recording angles of approx. 120° horizontal and approx. 60° vertical. The geometry of the club-shaped detection ranges can change depending on environmental influences (hot air from engine).
