We shall now describe a device for the rotation of a steering wheel.

摘要

The invention relates to a device for detecting the rotation of a volant.dans this device, several transmitters, which reflect or produce an infrared radiation or an electromagnetic radiation (2), are arranged on the steering wheel (1), it is provided a receiving unit (3) which receives the radiation (2) from the transmitters, and a signal processor detects from sequences of images received successively, of the transmitters the local modification of these sequences, and determines, from there, the direction of rotation, the angle of rotation or the speed of rotation of the steering wheel (1) .application in particular for motor vehicles.
