Abstract
A clutch device, which has at least one clutch, which can assume an open operating state and a closed operating state, in which a torque can be transmitted by the clutch, an actuator device for activating the clutch, and a sensor device, which has a motion sensor. In order to simplify the actuation strategy of the clutch device, the sensor device has an additional sensor, which detects whether the actuator device is in or near an actuator end position in which the clutch is in the open operating state thereof.
Claims5
A method for actuating and/or operating a clutch device that comprises at least one clutch, which can assume an open operating state and a closed operating state and which can transmit a torque, an actuator device for actuating the clutch, and a redundant sensor device for the actuator device having a movement sensor and an additional sensor, the additional sensor detects only whether the actuator device is situated in or near an actuator end position, the method comprising the following method steps:
- detecting, by using the additional sensor of the redundant sensor device, whether the actuator device is situated in or near the actuator end position in which the clutch is in the open operating state;
- and
- checking whether an actuator end a position information item, which is detected with aid of the movement sensor, corresponds with the signal of the additional sensor, and carrying out a calibration operation if there is no correspondence.
