The invention provides a hybrid electric vehicle control method and system, a computer and a readable storage medium, and the method comprises the following steps: when it is detected that a battery pack cannot be started and the whole vehicle is in a driving state at present, judging whether an engine is in a starting state at present; if it is judged that the current engine is in the starting state, whether a gear corresponding to a shaft where a driving motor is located is in a combined state or not is judged; if it is judged that the gear corresponding to the shaft where the driving motor is located is in the combined state, a TCU is requested to keep the gear corresponding to the shaft where the motor is located and a clutch in the pull-in state, an MCU is requested to enter a zero-torque control state, and DCDC enters a standby mode; and controlling the BMS to disconnect the high-voltage relay, requesting the MCU to enter a constant-voltage power generation mode, requesting the TCU to lock the clutch, and requesting the DCDC to enter the constant-voltage power generation mode. By means of the mode, when the battery pack cannot be started, the power battery pack relay is disconnected in time, the engine is started, the high-voltage system enters the constant-voltage power generation mode, and it is guaranteed that the whole vehicle can run at a low speed.
本发明提供了一种混合动力汽车控制方法、系统、计算机及可读存储介质,该方法包括当检测到电池包无法启用且当前整车处于驾驶状态时,判断当前发动机是否处于启动状态;若判断到当前发动机处于启动状态,则判断驱动电机所在轴对应档位是否处于结合状态;若判断到驱动电机所在轴对应档位处于结合状态,请求TCU保持电机所在轴对应档位与离合器处于吸合状态,并请求MCU进入零扭矩控制状态,以及DCDC进入待机模式;控制BMS断开高压继电器,请求MCU进入恒压发电模式,并请求TCU锁止离合器,以及DCDC进入恒压发电模式。通过上述方式能够在电池包无法启用时,及时断开动力电池包继电器,启动发动机,让高压系统进入恒压发电模式,保证整车可以低速行驶。
