An electronic clutch management system for motor vehicles with engines having butterfly valves. An actuator under the control of a micro-controller activates a clutch between the engine and a transmission as a function of an ECM sensor which senses the position of the butterfly valve. If the micro-controller breaks down or is disturbed in its function, the micro-controller control is switched off, and control of the actuator element is switched over from the micro-controller to a comparator which is driven directly by the ECM sensor and controls the actuator element to activate the clutch, i.e., into its disengaged or engaged position, in a sense opposite to the position of the butterfly valve. |
