- Electric power steering torque sensor (A91 b1) signal (toothed rack position)
- Front wheel angle
- Steering torque of the driver (Hands-Off/Hands-On Detection status)
- Remote Parking Pilot status (with code 503 (Pre-installation for Remote Parking Pilot))
- Status of parking space selection
- Parking brake, brake, ESP® status
- Remote Park Control KEYLESS GO status (with code 503 (Preinstallation for Remote Parking Pilot))
- Trailer operation status (with code 550 (Trailer hitch))
- Blind Spot Assist warning (with code 234 (Blind Spot Assist) or code 237 (Active Blind Spot Assist)) or Lane Keeping Assist warning (with code 238 (Active Lane Keeping Assist))
HSVL line
The image data from each of the following assembly parts is read in via a separate HSVL line:
- Reversing camera (B84/3) (with CODE 218 (Reversing camera))
- Left outside mirror 360° camera (B84/7) (with code 501 (360° camera))
- Right outside mirror 360° camera (B84/8) (with code 501 (360° camera))
- Blind Spot Assist brake request (with code 234 (Blind Spot Assist) or code 237 (Active Blind Spot Assist)) or Lane Keeping Assist brake request (with code 238 (Active Lane Keeping Assist))
- Steering wheel angle and steering wheel velocity
- Vehicle level (with code 489 (AIR BODY CONTROL))
- Status of PARKTRONIC button
- Status of parking system button
- Accelerator pedal position
- Ambient illumination status (with code 501 (360° camera))
- Outside mirror housing status (with code P49 (Mirror package))
Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.
Actuation of components
The parking system control unit actuates the parking system distance sensors and the parking system speaker (H13/4) via direct lines.
The signals for activation of the Audio/COMMAND display (A40/8) are sent by the parking system control unit via chassis FlexRay.
Output of signals
The parking system control unit also sends the following information or requests over the suspension FlexRay:
- Status of parking system
- Request to engage gear range
- Request to increase/reduce braking torque
- Control mode request (speed control/cruise control)
- Request for front wheel angle (steering angle)
- Information on distance to obstacle (remaining distance to obstacle)
- Request for braking mode
- Request for folding in outside mirror housings (with code P49 (Mirror package))
- Request for rear camera cover
- Remote Park Control request (with code 503 (Preinstallation for Remote Parking Pilot))
- Remote Park Control lock vehicle request (with code 503 (Preinstallation for Remote Parking Pilot))
- Request for ambient illumination (with code 501 (360° camera))
- Request for parking system display in Audio/COMMAND display
- Request to issue system or warning messages
The parking system control unit sends the image data via a HSVL line to the head unit (A26/17).
