Abstract

A method of determining and reducing vibrations caused by a clutch (3) in a drivetrain (1) of a motor vehicle, in which the disturbing vibrations are detected by a control and regulating unit aided by suitable sensors and, if predetermined limit values are exceeded, at least one device is actuated by the control and regulating unit in such manner that the disturbing vibrations are completely eliminated or at least reduced in amplitude. At least one torque sensor (8, 9, 10) is used to detect the occurrence of vibrations in the drivetrain (1) and the torque sensor (8, 9, 10) is used to determine vibration amplitude.
