Optical Steering-angle Sensor
All systems that influence driving dynamics are required alongside other data for the steering angle and steering-angle speed as the basis for calculation.
The steering angle as well as steering-angle speed are picked up by a non-contact optical measuring system, the optical steering-angle sensor.
The data of the optical steering-angle sensor are processed by the electronics in the steering column switch cluster and sent across the FlexRay to the Integrated Chassis Management.
Information such as the absolute steering angle or the steering-wheel-turn is calculated. The optical steering-angle sensor picks up a steering angle of -640°/+640°.
