Adaptive Air Suspension With PASM Inputs and Outputs

Air Suspension With PASM Inputs and Outputs







Input signals:
- Power supply for terminal 15, 30 and 31
- Body acceleration sensors and level sensors provide information about body movements, vertical movements and vertical acceleration as well as pitching, rolling and/or yawing
- Level sensors determine the vehicle level - level control/ride height adjustment
- The pressure sensor records the current air pressure in the individual components (pressure accumulator, air-spring elements)
- The temperature sensor records the ambient temperature of the compressor (compressor protection)
- Signals such as lateral acceleration, steering angle, brake pressure, engine torque and driving speed are sent to the control unit via CAN so that the vehicle setup can be adjusted accordingly
- Door status - no adjustments can be made while the doors are open and any adjustments that are in progress are interrupted when a door is opened
- The Sport, PASM and High Level buttons send an analogue signal into the A/C control unit and via CAN and the gateway control unit into the PASM control unit

Output signals:
- Damper valves - PASM control
- Additional valve - increases/reduces the air volume - spring rate adjustment
- Valve block - activates solenoid valves for controlling the air volume (vehicle height)
- Release valve in the valve block - releases air in the event of overpressure
- Change-over valves in the compressor - raise or lower the vehicle
- Compressor relay - switches compressor on/off
