Under/Oversteer Correction
DSC III monitors under/oversteer conditions through following components:
- The driver's desired steering angle - steering angle signal over CAN bus.
- Vehicle speed and speed differential at front wheels - wheel speed sensors.
- Dynamic forces of lateral acceleration and yaw placed on vehicle.
Expanded hydraulic control to individual wheel circuits is apparent when stabilizing a vehicle exhibiting an oversteer condition. Transmission system intervention also occurs during any ASC/DSC regulating phase. Through CAN bus communication, AGS control module is informed to delay any gear changes during regulation. This prevents any unwanted driveline dynamic changes during DSC regulation.
Though DSC III provides state of art, electronic correction of undesirable vehicle handling characteristics, it is important to remember vehicle stability is always subject to physical laws of centrifugal force and extreme road conditions. Good judgement and common sense on part of driver is still required.
