Adaptive Damper System Description
Overview
The adaptive damper system provides optimal damping force for all driving conditions by adjusting the damping force of each damper independently, improving the driving performance. The system is controlled by the adaptive damper control unit. With the adaptive damper system, roll-, pitch-, and yaw- motion of the vehicle can be controlled resulting in different driving characteristics. The adaptive damper control unit controls each damper solenoid with vehicle motion signals from other control units. Components
The adaptive damper system consists of the following primary components:
For locations of each component on the vehicle, refer to Component Location Index, and for functions of the system warning, refer to How to Troubleshoot the Adaptive Damper System. Control
The adaptive damper adjusts the damping force as in the following graph, depending on the change of the amount of electric current output from the adaptive damper control unit. Damping Force Characteristics Image
Integrated Drive-Mode System
The adaptive damper system has three control modes which correspond to the integrated drive-mode signal sent from the PCM via F-CAN. The ride control of the adaptive damper system by the Integrated drive-mode is shown below.
Fail Safe Mode
Depending on the severity of the error, the adaptive damper system will switch to one of four possible fail safe modes. In case of each fail safe mode a DTC is stored in the adaptive damper control unit.
