Abstract

The operation of an automated friction clutch between the output element of the engine and the input element of the variable-speed transmission in a motor vehicle is regulated by a fluid-operated system which receives signals from an evaluating circuit. The evaluating circuit receives signals from a number of sensors which monitor the RPM of the engine, the RPM of the input element of the transmission, clutch travel, the position of the throttle valve, the position of the shift linkage, the position of the gas pedal and other parameters. The fluid-operated system can select the condition of the clutch during starting, driving, acceleration, parking, driving in reverse and/or parking of the motor vehicle and/or during transitions between such stages of operation.
