Dynamic Stability Control DSC

Dynamic stability control DSC
The dynamic stability control is integrated in the ABS/DSC control unit. The rotational speeds of the wheels are monitored by sensors. Too high a speed difference between driven and non-driven wheels is detected as wheel slip. In addition, the system detects whether the vehicle is oversteered or understeered with the aid of the steering angle sensor.

Depending on the severity of the necessary intervention, the DSC initiates following measures:

For drive slip control:
- The EML control unit reduces the throttle opening
- The DME control unit adjusts the ignition timing in retard direction
- The DME control unit blanks out injection and ignition
- Spinning drive wheel is braked
For engine drag torque control:
- The EML control unit increases the throttle opening
