The invention belongs to the technical field of hybrid power vehicle power system control, and discloses a hybrid power vehicle driving system, a control system and a control method.The output end of an engine crankshaft is connected with a motor rotor shaft of a motor through a first clutch, and the output end of the motor rotor shaft is connected with an input shaft of a second clutch; an output shaft of the second clutch is connected with an input shaft of the transmission, and the output shaft of the transmission transmits power to wheels through the main speed reducer and the half shaft to drive an automobile to run. The control method comprises the following steps that the vehicle working condition is obtained, and the driving torque requirement and the engine rotating speed of each gear are calculated according to the vehicle working condition; a working mode is determined according to the driving torque requirement and the engine rotating speed of each gear; and the torque is output to the transmission mechanism in the corresponding working mode. According to the invention, the influence of the driving condition of the automobile on the work of the engine is minimized, so that the automobile realizes low emission and ultralow oil consumption, and the effects of environmental protection and energy conservation are achieved.

    本发明属于混合动力车辆动力系统控制技术领域,公开了一种混合动力车辆驱动系统、控制系统及控制方法,发动机曲轴输出端通过第一离合器与电机的电机转子轴连接,电机转子轴输出端与第二离合器的输入轴连接,并通过第二离合器的输出轴与变速器输入轴连接,变速器输出轴将动力经主减速器及半轴传递到车轮驱动汽车行驶。控制方法包括以下步骤:获取车辆工况,根据车辆工况计算驱动转矩需求与各档发动机转速;根据驱动转矩需求与各档发动机转速确定工作模式;在对应工作模式下输出转矩至传动机构。本发明将汽车行驶状况对发动机工作的影响降到最小,使汽车实现低排放及超低油耗,达到环保和节能效果。
