| 摘要 |
The invention relates to a sensor device (100) having an incremental sensor apparatus (40, 40', 40'') for a shaft which can rotate about a rotational axis, in particular for a steering shaft of a motor vehicle, wherein the incremental sensor apparatus (40, 40', 40'') is designed to sense at least one defined rotational angle position of the shaft. The incremental sensor apparatus (40, 40', 40'') has a transmitter element (41, 41'') and a receiver element (42) arranged fixed to the housing, wherein a signal (MInk_planar), which is emitted by the transmitter element (41, 41'') and transmitted along a signal path can be received by the receiver element (42), and on the basis of the signal (MInk_planar) which is received by the receiver element (42) it can be detected whether the shaft is in the defined rotational angle position (δdef) or not. If the shaft reaches the defined rotational angle position (δdef) a signal pulse can be generated. In this context, the transmitter element (41, 41'') is also arranged fixed to the housing, wherein a change in the signal (MInk_planar) can be brought about by a rotational movement of the shaft. In addition, the invention relates to a motor vehicle having a sensor device (100). |
