Abstract
A control system for a hybrid drive unit, in which an assist prime mover is connected through a transmission mechanism to an output member, to which a torque outputted by a main prime mover is transmitted, comprises gear shift controller for switching a shift control condition of said transmission in accordance with the action state of said main prime mover. A gear shift is inhibited in case a vehicle is run by an assist prime mover, and the gear shift is inhibited also in case the assist prime mover outputs a torque in connection with starting the main prime mover. A transmission is operated into a state just before starting the shifting operation in case the gear shift is inhibited in connection with starting the main prime mover.
