The invention belongs to the technical field of automobile control, and particularly relates to a method and a device for resetting a vehicle control unit of a hybrid electric vehicle, a medium and the vehicle control unit. In the driving process of the hybrid electric vehicle, before a vehicle control unit is reset, the driving circulation variable before resetting is stored in real time; after a vehicle control unit is reset, initialized and powered on, the vehicle control unit controls the hybrid vehicle to enter a pure electric mode, and a driving circulation variable before resetting is read; and according to the running cycle variable before resetting, the vehicle control unit controls the hybrid electric vehicle to be converted into a state stored by the running cycle variable before resetting. According to the method, the whole vehicle mode state machine can be quickly recovered under the reset working condition, and the situation that driving safety is affected due to power loss caused by mode disorder after reset is prevented.

    本发明属于汽车控制技术领域,特别涉及一种混动汽车整车控制器复位方法、装置、介质及整车控制器。混动汽车行驶过程中,在整车控制器复位之前,实时存储复位前行驶循环变量;整车控制器在复位初始化上电后,整车控制器控制所述混动汽车进入纯电模式,读取复位前行驶循环变量;根据复位前行驶循环变量,整车控制器控制所述混动汽车转换为复位前行驶循环变量所存储的状态。本发明可实现在复位工况下,快速恢复整车模式状态机,防止复位后因模式错乱而导致动力丢失,影响驾驶安全。
