The invention discloses a control method for a hybrid power system, the hybrid power system comprises an engine, a motor, a first clutch, a second clutch, a transmission and a power battery, the first clutch is an electromagnetic clutch, and the control method comprises the steps that the real-time electric quantity of the power battery is obtained; determining a target working mode of the hybrid power system according to the real-time electric quantity; under the condition that the target working mode is the pure electric mode, the first clutch is controlled to be disconnected so as to control the motor to independently drive the transmission; and under the condition that the target working mode is the pure fuel oil mode, the first clutch is controlled to be engaged, and the engine is controlled to independently drive the transmission. By means of the technical scheme, the electromagnetic clutch can enable the engine and the motor to be flexibly matched with the transmission so as to achieve multiple driving modes, and meanwhile the manufacturing cost of the system is reduced. And the technical problem that friction work of the engine needs to be overcome when the motor directly drives the engine to rotate can be solved, so that the energy utilization rate of the motor is improved.
本申请公开了一种用于混合动力系统的控制方法,混合动力系统包括发动机、电机、第一离合器、第二离合器、变速器以及动力电池,第一离合器为电磁离合器,控制方法包括:获取动力电池的实时电量;根据实时电量确定混合动力系统的目标工作模式;在目标工作模式为纯电动模式的情况下,控制第一离合器断开,以控制电机单独驱动变速器;在目标工作模式为纯燃油模式的情况下,控制第一离合器啮合,并控制发动机单独驱动变速器。通过上述技术方案,电磁离合器能够使得发动机和电机与变速器灵活匹配,以实现多种驱动模式,同时降低系统的造价成本。也可以解决电机直驱行驶发动机随转时,需克服发动机摩擦功的技术问题,以提高电机的能量利用率。
