Abstract
The operating unit for a vehicle is provided with a housing with a front face and an operating element which is arranged on the front face of the housing and has an operating surface. The operating element is mounted in a spring-elastic manner. Furthermore, at least one sensor is provided for detecting an actuation movement of the operating element. The operating unit additionally has at least one actuator for the feedback movement of the operating element in the case of an actuation movement of the operating element detected by the sensor as well as an analysis and control unit which is connected to the at least one sensor and to the actuator. The actuator is designed as an armature-type electromagnet with a first stator which has a first excitation coil, and an armature as a drive element. Furthermore, the armature is provided with a measuring coil to which a measuring voltage is applied when the magnetic flux generated by the first excitation coil flows through the armature. The first excitation coil and the measuring coil are connected to the analysis and control unit, and with the analysis and control unit it is possible to apply open-loop and/or closed-loop control to the force with which the armature of the actuator can move towards the first stator and/or the displacement movement of the armature out of its rest position and the return movement of the armature back into its rest position are adapted to be controlled and/or regulated.
