Road Sensing Suspension Description and Operation: Notes
The Continuously Variable Road Sensing Suspension (CVRSS) system consists of the following components:
- Continuously Variable Road Sensing Suspension (CVRSS) module (3)
- Four dampers contained in the 2 front struts (5 and 6) and the 2 rear shock absorbers (1 and 9)
- Four positions sensors (2, 4, 7, and 8)
- ALC air compressor module (10)
- Damper relay, not shown
- ELC relay, not shown
The CVRSS system with rear Automatic Level Control (ALC) controls damping forces in the front struts and rear shock absorbers in response to various road and driving conditions. The rear ALC portion of the system maintains a proper vehicle trim height under various vehicle load conditions. For more information on the ALC, refer to AUTOMATIC LEVEL CONTROL DESCRIPTION AND OPERATION (w/o F45) or AUTOMATIC LEVEL CONTROL DESCRIPTION AND OPERATION (w/F45) in Automatic Level Control.
The CVRSS module receives the following inputs: wheel-to-body position, vehicle speed, and lift/dive. The CVRSS module evaluates these inputs and controls actuators in each of the dampers independently to provide varied levels of suspension control.
