DSC sensor
The DSC sensor measures:
- Rotation of the vehicle around the vertical axis (yaw rate)
- Lateral acceleration of the vehicle
- Longitudinal acceleration of vehicle

The sensor element consists of 2 piezoelectric acceleration sensors. A mass is suspended on a spring in the measuring cell of the acceleration sensor. With an accelerates motion, 2 masses suspended on springs are also accelerated. The force necessary for this creates a mechanical voltage in the piezoelectrical material. The shift in electrical charge this creates is picked up with electrodes made of metal and processed as an electrical signal. The yaw rate is derived from the difference between the two acceleration signals. The DSC sensor thus delivers a yaw rate and an acceleration signal.
The longitudinal acceleration sensor is required for the drive-off assistant.
The DSC sensor is connected via the chassis and suspension CAN (F-CAN) with the DSC control unit as well as the steering column switch cluster.
The DSC sensor is supplied with voltage from the junction box.
