Abstract

A method of monitoring a torque transmission system with a manually switchable gearbox in the power train of a motor vehicle involves the utilization of at least one sensor unit at the input side of the torque transmission system to ascertain relevant positions of the shift lever of the gearbox and the driving torque of the engine of the motor vehicle. The thus obtained shift lever signals are memorized, together with comparison signals which are obtained as a result of filtering of the shift lever signals, and various characteristics of such signals are recognized and identified to indicate the intention of the operator of the vehicle regarding the switching of the gearbox. The thus obtained switching intention signals are transmitted to a controlled clutch operating system.
