Dynamic Stability Control (DSC): Notes
With the introduction of DSC systems, lateral dynamics were taken into account for the first time. The MK60 DSC III system will initiate a DSC regulation sequence if the control unit detects a difference between the drivers desired turning angle and the actual rotation angle of the vehicle. The control unit determines vehicle stability based on:
- Steering wheel angle
- Wheel speed
- Transverse acceleration forces
- Rotation angle and speed (yaw)
Once the control unit determines that the vehicle is in an unstable situation, it also identifies whether it is oversteering or understeering. This distinction is important because it determines which control strategy should be used to help stabilize the vehicle.
DSC regulation consist of :
- Engine intervention
- Engine and brake intervention (any wheel)
- Brake intervention
