Hybrid transmission control system

A transmission control system for a hybrid vehicle is comprised of a hybrid transmission (4, 7 and 8) including two motor/generators (MG1, MG2) and a controller (22) connected to the hybrid transmission. The controller is arranged to change the torque control of the motor/generator under the torque control to the revolution speed control and to change the revolution speed control of the other motor/generator under the revolution speed control to the torque control, when one of the torque of the motor/generator under the revolution torque control and the revolution speed of the motor/generator under the torque control becomes saturated.
