How It Works (E60, E61, E63, E64 up to 09/2005)

WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2006 BMW 530i, 2006 BMW 525i, 2006 BMW 330xi, 2006 BMW 330i, and 2006 BMW 330Ci. However, it is still accessible from the selected car via links, so may be relevant.

Each of the two DSC sensors supplies a rate-of-yaw signal and an acceleration signal. Any accelerated motion accelerates the spring-mounted suspended mass. The force needed to achieve this is generated by mechanical tension in the piezoelectric material. This results in a shift in the electric charge. Electrodes are used to detect this shift, which is output as an electric signal for processing.

The second DSC sensor implements redundancy in terms of registration of the signals for lateral acceleration and rate of yaw. The fact that 2 DSC sensors are used means that plausibility can be monitored. The two DSC sensors are triggered by the DSC control unit (excited every 10 milliseconds). Each time they are triggered, the two DSC sensors send their signals to the F-CAN.

NOTE: Only one DSC sensor from 09/2005. The 2nd DSC sensor is discontinued from 09/2005. One DSC sensor supplies redundant signals.
