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.

Method and apparatus for regulating the transmission of torque in power

The invention relates to a power train which is to be utilized in a motor vehicle and employs a hydrokinetic torque converter--lockup clutch--electronic control system assembly operating in such a way that the lockup clutch is already at least partially engaged while the engine of the motor vehicle is running but the vehicle is at a standstill. This reduces the likelihood of the development of shocks during shifting of a manual, automated or continuously variable transmission which receives torque from the output element of the torque converter. Another feature of the invention resides in the provision of a compact, lightweight and inexpensive design of the torus composed of the impeller, reactor and stator of the hydrokinetic torque converter.
