Parking system control unit component description - GF54.65-P-5002FQM
MODEL 218 as of model year 2015 with CODE 235 (Active Park Assist)
Location
The parking system control unit is located under the front passenger footwell lining.
Task
The parking system control unit is responsible for the following tasks:
- Controlling functions
- Reading in of sensors
- Evaluation of input factors
- Actuation of components
- Transmitting signals
Controlling functions
The parking system control unit controls the following functions:
- Parking system
- Active Parking Assist
Reading in of sensors
The input factors are read in via the following connections:
- Direct line
- Chassis CAN 2 (CAN E2)
Direct line
The signals from the following components are read via direct lines:
- Left front outer parking system distance sensor (B8/1)
- Left front center parking system distance sensor (B8/2)
- Left front inner parking system distance sensor (B8/3)
- Right front inner parking system distance sensor (B8/4)
- Right front center parking system distance sensor (B8/5)
- Right front outer parking system distance sensor (B8/6)
- Outer right rear parking system distance sensor (B8/7)
- Inner right rear parking system distance sensor (B8/8)
- Inner left rear parking system distance sensor (B8/9)
- Outer left rear parking system distance sensor (B8/10)
- Left rear center parking system distance sensor (B8/11)
- Right rear center parking system distance sensor (B8/12)
The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
Chassis CAN 2
The following signals, among others, are read in via chassis CAN 2:
- Circuit 15 status
- Engine running or drive train operational
- Wheel speed and wheel rotation direction
- Vehicle speed
- Parking system button status (N72/1s8)
- Gear range "R" engaged
- Ambient brightness
- Electrical power steering control unit status (N68)
- Electric power steering torque sensor (A91b1) signal (toothed rack position)
- Combination switch position (S4)
- Left multifunction steering wheel button group signal (S110)
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 following components are actuated via direct lines:
- Rear parking system warning indicator (A44/3)
- Instrument panel parking system warning indicator (A44/4)
- Parking system distance sensors
Transmitting signals
The parking system control unit transmits, among others, the following signals via chassis CAN 2:
- Request to display message or issue warning tone
- Parking system status indication request
- Electric power steering request (steering angle)
- Information on distance to obstacle (remaining distance to obstacle)
The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
