Abstract:
A control apparatus of a parallel hybrid electric vehicle comprising:an engine;an electric rotary driving source having both functions of a generator and a motor;a transmission device;a differential device having a first shaft connected to the engine, a second shaft connected to an output shaft of the electric rotary driving source, and a third shaft connected to the transmission device; anda coupling device for connecting and disconnecting between two shafts selected from the first to the third shafts,wherein the coupling device is made to enter a non-coupled condition at the time of start of the vehicle so that the torque of the electric rotary driving source is controlled to maintain the engine speed at a predetermined idling speed during the starting, and the coupling device is controlled to enter a coupled condition when rotational speeds of the first, second and third shafts of the differential device are synchronized with one another.
