The invention provides a power system control method and system of a hybrid power vehicle and the vehicle, and relates to the technical field of vehicle control. The power system control method comprises the following steps: judging whether a power battery has a power limitation fault or not; when it is judged that the power limited fault occurs in the power battery, torque control is conducted on the first motor and the second motor, meanwhile, the anti-shake function of the second motor is turned off, so that power generation of the first motor and power utilization of the load are kept consistent, and the current of the bus end of the power battery is kept to be zero; and performing voltage control on the first motor to enable the difference value between the actual voltage of the first motor and the set voltage to be within a preset difference value range. According to the control method, normal operation of the vehicle can be guaranteed, the problem that the vehicle cannot run and even the power battery breaks down due to the fact that the power of the power battery of the vehicle is limited is avoided, and the running safety of the vehicle under the condition that the power is limited is improved.
本发明提供了一种混合动力车辆的动力系统控制方法、控制系统及车辆,涉及车辆控制技术领域。本实施例的动力系统控制方法包括:判断动力电池是否发生功率受限故障;在判定动力电池发生功率受限故障时,对第一电机和第二电机进行扭矩控制,同时关闭第二电机的防抖功能,以使得第一电机的发电和负载用电保持一致,且保持动力电池母线端电流为零;对第一电机进行电压控制以使得第一电机的实际电压与设定电压的差值在预设差值范围内。本实施例的控制方法可以保证车辆正常运行的同时,避免因车辆动力电池的功率受限导致车辆无法行驶甚至导致动力电池出现故障的问题,提高车辆在功率受限情况下的行车安全性。
