The invention discloses an independent four-wheel drive hybrid power system of an automobile, which comprises an engine, motors, a motor controller, a battery pack, clutches and transmission shafts, the four motors respectively and independently drive four wheels through the transmission shafts, and the clutches are respectively arranged between the two front wheel motors and the transmission shafts. In the pure electric mode, the front-wheel motors are connected with the transmission shafts through the clutches to drive wheels, the rear-wheel motors operate in a matched mode to achieve independent four-wheel drive, in the hybrid mode, the clutches enable the two front-wheel motors to be separated from the transmission shafts and connected with the engine, and the front-wheel motors serve as starting machines to start the engine to operate. During high-speed cruise, the engine, the transmission shaft and the front wheel motor are connected together through a clutch, and the engine can directly drive wheels. The front wheel motor can be matched with the engine to output power and can also recycle redundant power of the engine to charge the battery pack, and the vehicle can be switched to a pure electric four-wheel drive mode at any time so as to deal with the conditions of sharp turning, getting out of trouble, climbing and rapid acceleration.

    本发明公开了一种汽车独立四轮驱动混合动力系统,动力系统包括发动机、电动机、电动机控制器、电池组、离合器、传动轴,四个电动机通过传动轴分别独立驱动四个车轮,两个前轮电动机与传动轴之间各装有一个离合器,纯电模式时前轮电动机通过离合器与传动轴连接驱动车轮,后轮电动机配合运转实现独立四驱,混动模式时离合器使两个前轮电动机与传动轴分离并且与发动机连接,由前轮电动机充当启动机使发动机启动运转,然后发动机带动前轮电动机发电通过电动机控制器驱动后轮电动机运转并且为电池组充电,高速巡航时发动机、传动轴、前轮电动机通过离合器连接到一起,发动机可以直接驱动车轮,前轮电动机既可以配合发动机输出动力也可以将发动机多余动力回收给电池组充电,车辆可以随时切换到纯电四驱模式以应对急转弯、脱困、爬坡、急加速的情况。
