Steering angle sensor

The steering angle as well as the steering-angle speed are picked up by a non-contact optical measuring system, the optical steering-angle sensor.

Data from the optical steering angle sensor are processed by the electronics in the steering-column switch cluster (SZL). These data are sent across the FlexRay to the integrated chassis management (ICM).

The steering-angle sensor picks up the following variables:

• Steering angle
• Steering wheel angular velocity (calculated in steering column switch cluster)
• Steering-wheel turns
