The invention relates to the technical field of hybrid vehicles, in particular to a reversing method and system of a hybrid vehicle and the hybrid vehicle. The reversing method of the hybrid electric vehicle comprises the following steps that S1, whether the vehicle is in a reverse gear or not is judged, if yes, the step S2 is executed, and if not, the gear state of the vehicle is continuously monitored; s2, exhaust of the engine is stopped; s3, the driving motor and the generator rotate reversely at the same time, the driving motor and the generator apply torque in the first direction to a gear ring and a sun gear of the planet row correspondingly, and at the moment, the engine is braked through exhaust; and S4, the reverse gear state is relieved, and exhaust of the engine is started. According to the reversing method of the hybrid electric vehicle, exhaust of the engine is stopped when the vehicle enters the reverse gear state, so that when the driving motor drives the wheels to rotate reversely, the crankshaft of the engine is driven to rotate, and meanwhile, the reverse torque similar to engine braking is achieved through compression of the piston on air.

    本申请涉及混动汽车技术领域,尤其涉及一种混动汽车的倒车方法、倒车系统以及混动汽车。该混动汽车的倒车方法包括如下步骤:S1、判断车辆是否处于倒挡,若是,则执行步骤S2,若否,则继续持续监测车辆挡位状态;S2、关闭发动机的排气;S3、驱动电机和发电机同时反转,驱动电机和发电机分别给行星排的齿圈和太阳轮施加第一方向上的扭矩,此时发动机利用排气制动;S4、倒挡状态解除,打开发动机的排气。该混动汽车的倒车方法,通过在车辆进入倒挡状态时,关闭发动机的排气,能够使驱动电机驱动车轮反转时,带动发动机的曲轴转动的同时,利用活塞对空气的压缩实现类似发动机制动的反向力矩。
