OPERATING UNIT FOR A VEHICLE

摘要

The invention relates to an operating unit (10) for a vehicle, said unit being provided with a housing (26) with a front face and an operating element (12) which is arranged on the front face of the housing (26) and has an operating surface (14). The operating element (12) is mounted in a spring elastic manner. Furthermore, at least one sensor (28) is provided for detecting an actuation movement of the operating element (12). The operating unit (10) additionally has at least one actuator (32) for the feedback movement of the operating element (12) when an operating element (12) actuation movement is detected by the sensor (28). The operating unit also has an analysis and control unit (30) which is connected to the at least one sensor (28) and to the actuator (32). The actuator (32) is designed as an armature-type electromagnet with a first stator (48), which has a first excitation coil (52), and an armature (46) as a drive element (34). Furthermore, the armature (46) is provided with a measuring coil (56) to which a measurement voltage is applied when a magnetic flux generated by the first excitation coil (52) flows through the armature (46). The first excitation coil (52) and the measuring coil (56) are connected to the analysis and control unit (30), and with the analysis and control unit (30) it is possible to apply open-loop and/or closed-loop control to the force with which the armature (46) of the actuator (32) can move towards the first stator (48) and/or to the movement of the armature (46) out of the armature rest position and the return movement of the armature (46) back into the rest position.
