Parking Assist Components
The parking assist system is made up of the following components:
- Advanced parking assist control module
- Front object alarm sensors
- Rear object alarm sensors
- Parking aid front side sensors
- Parking assist switch
- Parking assist switch indicator
Advanced Parking Assist Control Module
The advanced parking assist control module provides an 8 V reference and a low reference to the 10 object alarm sensors. The advanced 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 advanced parking assist control module will send a data message via serial data to the radio requesting an audible alert.
Object Alarm Sensors and Parking Aid Side Sensors
The 10 object alarm 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 advanced parking assist control module.
Parking Assist Switch / Parallel 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. If the vehicle is equipped with parking assist and advanced parking assist, both use the same button to operate the systems. The parallel parking assist can be activated and deactivated by pressing the parking assist switch for approximately one second. If one system is active, it can be switched between both systems by pushing the button accordingly shorter or longer.
Parking Assist Switch Indicator
The indicator in the parking assist switch shows the status of the parking assist. If the lamp is ON, the parking assist is activated.
Parking Assist Indicator
The parking assist indicator in the instrument panel cluster is activated if the object detection detects a malfunction. If the indicator is ON, the parking assist is disabled.
