  • Patent number: 5067599
    Abstract: For controlling a motor vehicle friction clutch (3) which is operated by an actuating drive (7) during parking maneuvers, an output adjusting device (19) of the internal combustion engine (1) is unaffected over a limited initial pedal travel (.alpha..sub.0) of the accelerator pedal (17). According to the pedal position at any given time, the actuating drive (7) of the clutch (3) is controlled within the initial pedal travel. According to the pedal position and in keeping with a predetermined first signal characteristic a desired torque signal is generated and the actuating drive (7) is positioned as a function of the desired torque signal and in keeping with a predetermined second signal characteristic. In the clutch position determined by the pedal position, an actual torque signal is generated which represents the torque of the internal combustion engine (1) and it is compared with the desired torque signal.
