Circuit/System Description

Circuit

Description

Reference Voltage

Regulated voltage supplied by the control module.

Signal

The control module input circuit has an internal resistance connected to 7.0-12.5 V.

Low Reference

Grounded through the control module.

Component

Description

K182 Parking Assist Control Module

The assembly has several functions:

Parking Assist

B306 Parking Assist Sensor

The sensors can send and receive ultrasonic sounds. First a short sound is emitted. If there is an obstacle in front of the sensor, the obstacle will reflect the sound back to the sensor. The time difference between sending and receiving is the measure for the distance to the obstacle.
