Device for detecting the angle position of a motor vehicle steering wheel

摘要

The invention relates to a device for detecting the angle position of the steering wheel of a motor vehicle. The aim of the invention is to provide a device of this kind in which the technical problem of determining the absolute angle position of the steering wheel in a measuring range greater than 360° is solved without the need for mechanical reduction gears and such like. This is achieved by means of a measurement system comprising at least one coil system which cooperates with an electrically conductive structure configured on/in a flexible flat cable (6). The flexible flat cable (6) is wound in a winding gap situated between the outer lateral surface (3) of an inner cylindrical rotor (1) joined to the steering gear shaft and the inner lateral surface (4) of an outer cylindrical stator (2) joined to the steering column, in such a way that its one end is fixed to the rotor (1) and its other to the stator (2).
