DSC Sensor
WARNING: This page does not describe the selected car, but rather 46 other vehicles, including the 2008 BMW M5, 2008 BMW 650i, 2007 BMW Z4, 2007 BMW M6, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
The DSC sensor registers lateral acceleration and calculates the yaw rate.
("Yaw" is the movement of the vehicle about the vertical axis, e.g. when the car is cornering).
The main-beam assistant uses the yaw rate to improve evaluation when the car corners. The DSC sensor is underneath the driver's seat. For safety reasons, cars with active front steering have a second DSC sensor underneath the front passenger's seat.
