ActiveCN101342902AIncrease speedGreat driving forceHybrid vehiclesElectrical controlEngineeringHybrid vehicle

The invention relates to an engine starting gear used in a mixing motor vehicle power transmitting device. In the engine starting gear, the engine starting gear (94) changes a starting method of an engine (8) when an automatic speed changing part (20) executes speed changing relative to the starting method of the engine (8) when the automatic speed changing part (20) is not variable. Therefore, the starting operation of the engine (8) negatively affects the speed changing of the automatic speed changing part (20). During speed changing period of the automatic speed changing part (20), the starting operation of the engine (8) is started, compared with responsibility realized on an acceleration required by a driver in starting operation after the automatic speed changing part (20) has completed the speed changing, thereby furthermore increasing responsibility.
