A hybrid vehicle drive system including an internal combustion engine, a motor-generator, a speed shift mechanism including a first and second frictional engagement mechanisms, a torque limiter interposed the motor generator and the speed shift mechanism in a power transmission path transmitting from the internal combustion engine to an axle, and a controller controlling the speed shift mechanism so as to disengage the first frictional engagement mechanism and engage the second frictional engagement mechanism. The controller is configured to perform controlling the speed shift mechanism so as to increase an engaging force of the second frictional engagement mechanism during switching from high speed stage to low speed stage when an occurrence of slipping is detected than when the occurrence of slipping is not detected.
