The torque capacity of a torque transmitting device incorporated in a power transmission system between an output shaft of a hydrodynamic power transmission and a drive shaft of a vehicle is so controlled as to provide a predetermined rotation speed difference between the input and output shafts of the hydrodynamic power transmission when the vehicle is in a state of standstill, thereby reducing creeping of the vehicle in the standstill state and also improving the response of the power transmission system at the time of vehicle starting. When the vehicle is to be started, the torque capacity is feedback-controlled so as to change the rotation speed of the output shaft of the hydrodynamic power transmission at a predetermined changing rate, thereby ensuring smooth starting without any appreciable shock. |
