Abstract
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.
