ABSTRACT:
A parallel hybrid electric vehicle includes an engine and a motor/generator as a rotary driving source. A differential device has a first shaft connected to the engine, a second shaft connected to the motor/generator, and a third shaft connected to a transmission device. The first and the second shafts can be coupled by a direct clutch. At the time of start of the vehicle with the engine in an idling condition, the motor/generator is controlled to enter a reverse rotation power generating condition, and the engine speed is maintained near an idling speed. After the start of the vehicle, when the motor/generator is in a forward rotation condition, the motor/generator is controlled to operate as a motor to maintain the engine speed at a target speed, and when the engine speed and the motor/generator speed coincide with each other, the direct clutch is made to enter a coupled condition thereby to prevent the occurrence of coupling shock, and also to reduce a driving time of the motor/generator.
