General
The parking system control unit evaluates the information from the distance sensors in the front and rear areas of the vehicle. The distance sensors detect obstacles in front of and behind the vehicle. Whenever an obstacle is detected, the parking system control unit generates a warning according to the distance between the vehicle and the obstacle.
The parking system control unit searches for suitable parking spaces based on the side distance sensors at the front. Detected parking spaces and any usable parking options are displayed to the driver.
The parking system control unit calculates a suitable path (trajectory) and provides assistance when entering and exiting a parking space. For vehicles equipped with a trailer hitch, the parking system control unit assists the driver during reverse maneuvering with a trailer (as from market launch of model 167). The parking system control unit is connected to the network architecture of the vehicle.
Function
To implement the functions, the parking system control unit processes information such as the following:
- Engine/drivetrain operating status
- Terminal status of terminal 15
- Wheel speed and wheel rotation direction
- Engaged gear (vehicles with manual transmission) or engaged drive range (vehicles with automatic transmission)
- Acceleration/yaw rate
- Status of Electronic Stability Program (ESP®)
- Electric power steering status
- Rack position of electric power steering
- Front wheel angle
- Status of parking space selection
- Status of parking brake, brake, ESP®
- Trailer operation status (vehicles with trailer hitch)
- Status of trailer hitch turning angle sensor (vehicles with trailer maneuvering stabilization)
- Blind Spot Assist warning (vehicles with blind spot monitoring)
- Blind Spot Assist braking request (vehicles with blind spot monitoring)
- Steering wheel angle and steering wheel velocity
- Vehicle level (vehicles with air suspension)
- System status
- Accelerator pedal position
- Status of surround lighting (vehicles with Parking Package)
- Status of outside mirror housings (vehicles with Mirror Package)
The parking system control unit evaluates these input parameters and sends the following information and requests:
- Status of parking system
- Information on distance to obstacle (remaining distance to obstacle)
- Requests:
- Engage drive range (vehicles with automatic transmission).
- Increase/reduce braking torque.
- Control mode (speed control)
- Adjust front wheel angle (steering movement).
- Fold in outside mirror housings (vehicles with Mirror Package).
- Actuate rear camera cover.
- Switch on surround lighting (vehicles with Parking Package).
- Emit warning tones, system messages or warning messages.
