One kind of hybrid gas-electric hybrid system control method for tandem rotation parallel

The present invention discloses a hybrid gas-electric hybrid system control method for series parallel transfer, when the vehicle enters the parallel condition satisfied, if the engine starting unit is not completed, the speed control using the ISG, the motor speed-based target rotational speed, the engine gas at the set speed n1, n2 rotational speed is set at the ignition, after a successful starting ISG still using machine speed control, follow the main motor speed, the engine is controlled to throttle control, and given the appropriate throttle value; when the engine and main motor speed less than a set speed difference, the clutch in conjunction with, the vehicle enters the parallel mode. Outstanding feature of this method is the parallel mode switch in series, the ISG motor with speed control, follow the main motor speed, and the engine throttle control, and is given the appropriate value of the throttle, fast response speed, and the engine response into the parallel mode speed ratio of the engine used in the process control and the throttle value is 0. faster manner, the hybrid system after clutch engagement without power interruption.
