The invention discloses a hybrid power driving system, a heavy transport vehicle and a control method of theheavy transport vehicle, and belongs to the technical field of tractors. The hybrid power driving system comprises an engine arranged below a cab of the heavy transport vehicle, a driving motor located on one side of the engine and arranged on a vehicle body main body of the heavy transportvehicle, a clutch arranged between the engine and the driving motor, and a high-voltage assembly located on one side of the middle of the vehicle body main body; the clutch has a closed state and an open state, when the clutch is in the closed state, the engine and the driving motor are connected in parallel, and when the clutch is in the open state, the engine and the driving motor are mutually independent; and the high-voltage assembly comprises a box body, a power battery located at the bottom of the box body, a high-voltage distribution box located above the power battery and a direct-current step-down transformer located above the high-voltage distribution box. According to the invention, the oil consumption of the engine can be greatly reduced, the exhaust emission is reduced, the dynamic property of the whole vehicle is improved, and the influence on the environment is reduced.

    本发明公开了一种混合动力驱动系统、重型运输车及其控制方法,其属于牵引车技术领域,混合动力驱动系统包括发动机,发动机布置于重型运输车的驾驶室的下方;驱动电机,位于发动机的一侧,且驱动电机设置于重型运输车的车身主体上;离合器,设置于发动机及驱动电机之间,离合器具有闭合状态和断开状态,离合器处于闭合状态时,发动机与驱动电机并联,离合器处于断开状态时,发动机与驱动电机相互独立;高压组件,位于车身主体中部的一侧,且包括箱体,位于箱体的底部的动力电池,位于动力电池的上方的高压配电盒及位于高压配电盒的上方的直流降压器。本发明使得发动机的油耗能够大幅度减小,且减小了废气排放量,提升整车动力性,降低了对环境的影响。
