<p>An automatic clutch 3, for a motor vehicle, comprises a control unit 13 that adjusts, via a computer unit 13a, the torque transferred by the clutch 3 in dependance upon inputs from, for example, engine electronic unit 50 and ABS electronic unit 60 which processes signals from brake sensor 41. The units 13, 50 and 60 are connected through a data bus 70 which transfers first brake operating data from the ABS unit 60 to the control unit 13. If a failure occurs in the data bus 70, the control unit 13 switches into emergency mode, which controls a creeping forward of the vehicle, and second brake operating data is supplied from the brake sensor 41 to the control unit 13 by digital brake input 71. If the brake input 71 signals that brake activation exist the clutch 3 is disengaged and if no activation exist the clutch is engaged. Other sensors are used to detect, for example, wheel speeds, engine speeds, throttle valve position, gear position etc. The control unit 13 operates an electric motor 12 which, via gearing, adjusts a position of a master cylinder 11 that is connected to a slave cylinder 10 by a hydraulic line 9.</p> |
