A driving mode transition controller is provided for a hybrid vehicle equipped with engine, motor-generator, and clutch installed between the engine and the motor-generator, wherein the engine is started by engaging the clutch and using the motor-generator as a starter motor for the engine when making a mode transition from an "EV mode" which utilizes only motor-generator MG as the power source to an "HEV mode" which includes the engine E as part of the power source. The controller uses an acceleration intention determination module to control the controls the maximum torque capacity of the clutch at the time of clutch engagement such that the weaker a driver's intention to accelerate is determined to be, the lower the rate of engine rpm rise becomes when making the mode transition from EV mode to HEV mode.
