Abstract

There are disclosed a method of and an apparatus for regulating the operation of a friction clutch or another torque transmission system in the power train of a motor vehicle. The regulation is such that the operator of the vehicle is informed of a prevailing or impending condition which entails or is about to entail damage to the system or to the entire power train. Such situation can arise in response to excessive and/or prolonged slip of abutting friction surfaces in a friction clutch, overheating of one or more parts of the system for any other reason(s), as a result of improper selection of the transmission speed for starting of the vehicle and/or due to excessive wear upon the friction linings and/or other parts. The remedial undertaking can include such regulation of the system that the ride become uncomfortable to the occupant(s) of the vehicle and/or automatic elimination of the cause(s) of unsatisfactory torque transmission.
