The invention relates to a hybrid power vehicle retarding method and a vehicle. The method comprises the steps that judging and executing retarding control according to operation of a driver; controlling a generator to drag an engine, enabling the engine to be in an exhaust braking state, and maintaining the engine to a set rotating speed; calculating the power consumption of the generator at a set rotating speed, and calculating the regenerative braking torque of a driving motor according to the power consumption; and controlling the driving motor to output the regenerative braking torque. The problem that when regenerative braking of the hybrid power vehicle driving motor is used for vehicle retarding, retarding fails due to the fact that the energy storage device is fully charged is solved, meanwhile, equipment is not added, the structure of the vehicle does not need to be changed, and the driving safety of the vehicle during long-time downhill is guaranteed.

    本发明涉及一种混合动力车辆缓速方法及车辆,根据驾驶员的操作判断执行缓速控制;控制发电机拖动发动机,并使其处于排气制动状态,并维持发动机至设定转速;计算设定转速下发电机的耗电功率,根据所述耗电功率计算驱动电机再生制动扭矩;控制驱动电机输出所述再生制动扭矩。本发明克服了混合动力车辆驱动电机的再生制动在用于车辆缓速时,因储能装置电量充满而导致的缓速失效的问题,同时不增加设备,无需改变车辆结构,保证了车辆在长时间下坡的行车安全。
