ANGLE MEASURING PROCESS AND DEVICE FOR ROTARY BODIES

摘要

A process and device are disclosed for measuring the rotation angle of a rotary body, in particular a body capable of rotating over more than 360 DEG . The rotary body co-operates with at least two other rotary bodies, for example toothed wheels, whose angular position is determined by means of two sensors. The relative position of the rotary body is derived from the thus determined angular positions. For clear indications to be given, all three rotary bodies or toothed wheels must have a predetermined number of teeth. The process and device may be used for example to determine the steering angle of a motor vehicle.
