Cumulative steering-angle sensor and steering angle sensor: Construction
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.
The cumulative steering angle sensor consists of a magnetoresistive element and a permanent magnet. The permanent magnet is mounted on the end of the steering pinion. The cumulative steering angle sensor is connected to the AL control unit and the DSC control unit by the F-CAN (chassis CAN = sub-bus of the PT-CAN). The angles measured by the cumulative steering angle sensor are signalised by the AL control unit. The DSC control unit uses calculated values delivered by the AL control unit through the F-CAN. Moreover, the DSC sensors and the steering angle sensor in the steering column switch cluster (SZL) are also connected to the F-CAN.
