Steering Wheel Angle Sensor for Vehicle Dynamics Control Systems 970382

Since 1995, Bosch has produced the Vehicle Dynamics Control Systems for passenger cars. In these systems the Steering Wheel Angle Sensors are used as the reference for other sensors, and for the whole system. The main requirements for these sensors are a high level of inherent safety and the absolute measuring of the steering wheel position, within the whole steering range, immediately after power on. The other requirements are as usual for automotive applications mass producibility, low cost and a high resistance against environmental influences. This paper describes a new steering wheel angle sensor that is under development, in comparison to the sensor in production.
