Active Yaw Control System
Brake control modules (BCM) with DSTC use continuous information from the different sensors in the system to calculate the positions of the steering wheel and car. The brake control module (BCM) calculates the driving style by measuring:
- steering angle
- steering angle speed
- engine torque
- the vehicle speed
- brake pressure.
The brake control module (BCM) also calculates the behavior of the car by monitoring:
- yaw rate
- lateral acceleration.
When the differences between the intended direction of the driver and the actual direction exceeds a certain level, active yaw control regulates the engine torque (stability function). This maintains the lateral stability of the car under most driving conditions. Active yaw control also activates the individual brake control to regulate the separation and electronic shuttle valves as well as the inlet and outlet valves. This should correct the vehicle in the event of a skid.
