摘要:
A mechanical component (100) for a motor vehicle has a test region (102) and a deformation element (104) mechanically coupled to the test region (102). When the mechanical component (100) is in operation and is subject to a stress load, the test region (102) undergoes deformation. The deformation element (104) is configured to respond to the deformation of the test region (102) by undergoing deformation which is greater than that experienced by the test region (102) and which can be detected by a magnetic field sensor (120, 122).

The actuation device is characterized by a spring element (4) which is disposed within the effective connection (W) between the actuating lever (2), the force-generating element (3) and the articulation (8), the spring rate thereof being known. The invention allows the determination of both the position of the actuating lever and the actuating force exerted on the actuating lever by means of the spring element and using only a single position sensor. In this way, a complete emulation of the haptics of a mechanical actuating lever can be achieved.
