An operating apparatus for a vehicle component comprises an operating panel () as well as an electric motor () mechanically coupled thereto with an unbalance mass. A detector () can capture the contact of the operating panel () by a user. A sensor () is provided in order to set exactly the number of revolutions of the electric motor in response to the contact of the operating panel by a user. The number of revolutions of the rotor is determined via this sensor.

Operating apparatus for a vehicle component and method for producing feedback

An apparatus for heating a steering wheel and for detecting a steering wheel contact comprises a steering wheel armature () made from electrically conductive material and an electric heating conductor () arranged outside of the steering wheel armature (). The apparatus further comprises a control and evaluation device () connected to the steering wheel armature () and the electric heating conductor () by means of which control and evaluation device the electric heating conductor () is repeatedly operated temporarily during a heating operation as a heating element for heating the steering wheel and temporarily during a measuring operation as a sensor element for detecting a steering wheel contact. The control and evaluation device () is configured so as to maintain the steering wheel armature () on a predetermined and especially constant potential at least during each measuring operation.

Apparatus and method for heating a steering wheel and for sensing contact with the steering wheel

A method of controlling the motor speed of an electric retractor motor () of a belt retractor () for reducing a belt slack in the comfort mode comprises the following steps of:

Method for controlling the speed of an electric motor of a belt retractor

In a vehicle safety system with a vehicle steering wheel, which has a steering wheel rim, and with at least one capacitive sensor which detects an alteration to an electric or electromagnetic field, the sensor is arranged in or on the steering wheel rim.

Vehicle safety system

A device for determining an absolute angle of rotation of a rotational axis has a first measuring device for measuring an angle of rotation in a limited first measuring range and a second measuring device for determining an absolute angle range. The second measuring device transforms a rotation of the rotational axis into a linear shift.
