Abstract
A valve train device includes a shaft having one or more actuation contours for actuating at least one actuation element of a valve of a combustion engine, and the actuation contours being arranged on the shaft so as to rotate therewith. A sensor unit including one or more sensors is provided, and each of the one or more sensors has a spatial sensing area for sensing a physical variable. In at least one axial position, an actuation contour of the one or more actuation contours is arranged at least partially in the spatial sensing area of a sensor of the one or more sensors.
Claims31
A valve train device comprising:
- a shaft;
- one or more actuation contours for actuating an actuation element of a valve of a combustion engine, the one or more actuation contours being associated with the shaft so as to rotate with the shaft;
- and
- a sensor unit including at least two sensors, each of the at least two sensors having a spatial sensing area for sensing a physical variable,
- wherein the shaft, the one or more actuation contours, and the sensor unit are configured and arranged such that, in at least one axial position, an actuation contour of the one or more actuation contours is arranged at least partially in the spatial sensing area of a sensor of the at least two sensors,
- wherein the valve train device further comprises an evaluation unit configured to output an error message if at least two of the at least two sensors detect a presence of the actuation contour of the one or more actuation contours in their respective spatial sensing area over a predetermined period of time.
