The invention discloses an automobile hybrid power driving system, and belongs to the field of automobile application. The driving system comprises a hybrid power system used for driving a wheel driving system, and the hybrid power system is characterized in that an output shaft of an engine provided with a first one-way clutch is connected with a first planetary mechanism; the driving motor connected with the power battery is connected with the second planetary mechanism, the power battery is connected with the first planetary mechanism through the generator, and the power battery is connected with the second planetary mechanism through the driving motor; the power mixing part comprises a mixing connecting shaft connected with the two planetary mechanisms, a second one-way clutch is further arranged on the mixing connecting shaft, and a third clutch is further arranged on the second planetary mechanism or the mixing connecting shaft. The gear shifting device has the advantages that smoothness is achieved, and the jerking feeling of gear shifting is avoided; the number of clutches which are frequently opened and closed is reduced to 1; meanwhile, a gearbox structure is omitted, the motor power does not need to be too high, and therefore cost is saved, and the same price of oil and electricity can be achieved.

    本发明公开了一种汽车混合动力驱动系统,属于汽车应用领域。该驱动系统包括:用于驱动车轮驱动系统的混合动力系统,混合动力系统包括:设置有第一单向离合器的发动机的输出轴与第一行星机构连接;与动力电池连接的驱动电机连接第二行星机构,动力电池通过发电机与第一行星机构连接,动力电池通过驱动电机与第二行星机构连接;动力混合部包括连接两组行星机构的混合连接轴,混合连接轴上还设置有第二单向离合器,在第二行星机构或混合连接轴上还设置第三离合器。本发明的优势在于平顺性,不会有换挡的顿挫感;将时常开启闭合的离合器数量降低到1个;同时省去了变速箱结构,电机功率不需要太高,从而节省成本,可以做到油电同价。
