Front and Rear Parking Assist Control Module

The front and rear parking assist control module provides a 12 V reference and a low reference to the 10 object sensors. The front and rear parking assist control module receives individual signals from each of the eight sensors and determines the location and distance of an object based on these inputs. While driving as speeds less than 8 km/h (5 MPH) and an object is detected, the front and rear parking assist control module will send a data message via serial data to the radio requesting an audible alert.

Front, Rear and Side Object Sensors

The 10 object sensors are located in the front and rear bumpers of the vehicle. The sensors are used to determine the distance between an object and the bumper. Each sensor emits an ultrasonic frequency which is reflected off any object located in front of or behind the vehicle. These reflections are received by the sensors. The time difference between the emission of the frequency and when the reflection is received is used to determine the distance to the object. The sensors report this information to the front and rear parking assist control module.

Parking Assist Switch

The parking assist can be enabled and disabled by pressing the parking assist switch. When driving at speeds less than 8 km/h (5 MPH) or when engaging the reverse gear, the parking assist is activated. By subsequently pressing the parking assist switch the parking assist can be disabled again.

Parking Assist Switch Indicator

The indicator in the parking assist switch shows the status of the parking assist. If the LED is ON, the parking assist is activated.

Automatic Parking Assist Switch

The automatic parking assist can be activated and deactivated by pressing the parking assist switch for approximately one second.
