Dynamic Standstill Detection (DSD)

The DSD mode is used if the ABS control module cannot operate the brakes or achieve a minimum deceleration rate, and the EPBCM has no valid wheel speed signals. In the DSD mode, the EPBCM uses the G sensor to monitor deceleration. To maintain vehicle stability, the EPBCM initially applies a low clamp load to the park brakes, then increases the clamp load in steps. When the G sensor signal indicates the vehicle has stopped, the EPBCM fully applies the park brake.
