Timed controlled engaged state of an automatic clutch

An automatic clutch 3 is controlled by a control unit 13 receiving signals from various sensors, eg clutch position sensor 14, gear position sensors 19a, 19b throttle sensor 31, brake sensor 41 etc. If, for example, the control unit 13 receives no new data or implausible data from the clutch positio...

More Information
Summary:An automatic clutch 3 is controlled by a control unit 13 receiving signals from various sensors, eg clutch position sensor 14, gear position sensors 19a, 19b throttle sensor 31, brake sensor 41 etc. If, for example, the control unit 13 receives no new data or implausible data from the clutch position sensor 14, the control unit 13 recognises it as a fault or failure and enters an emergency operating control in which the clutch 3 is controlled in a time dependent manner, eg by pulse-width-modulation etc, wherein engagement and/or disengagement of the clutch 3 takes place at a lower drive/current output than in a normal operation. An electric motor 12 is operated by the current so as to produce the required drive which operates, via gearing, a hydraulic master cylinder 11 coupled to a slave cylinder 10 that operates the clutch 3. The clutch 3 may be a dry friction clutch, multi-plate clutch, magnetic powder clutch or a bridging clutch.
