ABSTRACT:
An electronic control system for a motor vehicle friction clutch and which has an engine speed sensor, a reference signal generator, and a clutch actuator responsive to an error signal E derived from engine speed and reference signals V.sub.1 and V.sub.R respectively. The error signal E is fed into an integrator having two operation modes, dependent upon whether a capacitor in the integrator circuit bypassed by the error signal E or not. With the capacitor initially bypassed by the error signal E the integrator has unity gain, and with the capacitor subsequently placed in the error signal path the integrator has high gain. By having two response modes the time delay between the error signal E reaching its trigger point and the clutch actuator responding is greatly reduced.
