The invention relates to the technical field of engines and discloses a series-parallel engine and a control method thereof. The engine comprises an engine body, an internal combustion engine, a driving shaft, a driven shaft, a transmission belt, a clutch and a motor, wherein the internal combustion engine is arranged in the engine main body; the driving shaft is arranged in the engine body and connected with the power output end of the internal combustion engine; he driven shaft is arranged in the engine main body and is opposite to the driving shaft; the driving belt is connected with the driving shaft and the driven shaft; the clutch is arranged on one side of the driven shaft and used for controlling the transmission belt to be separated from or connected with the driven shaft; a poweroutput end of the motor is connected with the driven shaft and used for driving the driven shaft to rotate. The engine is advantaged in that a transmission belt is adopted to replace a traditional CVT speed change system, transmission efficiency is improved, and production cost is reduced; meanwhile, the structure is simpler, the size is smaller, and requirements of a motorcycle power system aremet.

    本发明涉及发动机技术领域,公开了一种混联式发动机及其控制方法,所述发动机包括:发动机主体、内燃机、主动轴、从动轴、传动带、离合器、电机;所述内燃机设置于所述发动机主体内;所述主动轴设置于所述发动机主体内,且与所述内燃机的动力输出端连接;所述从动轴设置于所述发动机主体内,且与所述主动轴相对设置;所述传动带连接所述主动轴和所述从动轴;所述离合器设置于所述从动轴一侧,用于控制所述传动带与所述从动轴分离或连接;所述电机的动力输出端与所述从动轴连接,用于驱动所述从动轴转动。本发明采用传动带代替传统的CVT变速系统,提高传动效率,降低了生产成本;同时结构上更为简单,体积更小,符合摩托车动力系统的需求。
