Description And Operation: Description
The Parking Assist Module (PAM) has the following characteristics:
- It receives power supply for its operation.
- It provides power supply to the 4 sensors.
- It receives signals from the 4 ultrasonic sensors.
- It manages the presence of a possible trailer: it is configured to deactivate the rear sensors when a trailer is present.
- It communicates and transmits data over the high-speed Controller Area Network (CAN)-C2 network.
If a fixed tow hook is present, the signal "Trailer presence" informs the PAM to deactivate the rear sensors if a trailer is attached to the vehicle. The signal "Trailer presence" is sent by the Trailer Tow Module (TTM) via CAN-BH.
To ensure the proper operation of the system when the trailer is not attached to the vehicle, the PAM control unit changes the sensor detection area range in order to take into account the space occupied by the tow hook.
Semi-automatic parking control unit PAM
The semi-automatic parking control unit PAM has the following characteristics:
- It receives power supply for its operation.
- It provides power supply to the 12 sensors.
- It receives signals from the 12 ultrasonic sensors.
- It manages the presence of a possible trailer: it is configured to deactivate the rear sensors when a trailer is present.
- It communicates and transmits data over the high speed CAN-C2 network.
The PAM cannot be adjusted or repaired and, if damaged or ineffective, it must be replaced with a new unit. The PAM software is flash programmable.
