The invention provides an engine starting method of a hybrid electric vehicle, a vehicle control unit and a vehicle. Storage battery information of the vehicle, current information of DC/DC and engine information are obtained; inputting the engine information into an engine starting current prediction model, so that the engine starting current prediction model predicts the engine starting current according to the engine information; determining the discharge current of the storage battery according to the storage battery information and the starting times of the engine; determining a target storage battery discharge current according to a storage battery actual discharge current and a storage battery discharge current in the storage battery information; and if the discharge current of the target storage battery, the current information of the DC/DC and the starting current of the engine meet the preset 12V starting condition, a 12V starter on the vehicle is triggered, so that the engine of the vehicle is started through the 12V starter.
本发明提供一种混合动力汽车的发动机启动方法、整车控制器及车辆,获取车辆的蓄电池信息、DC/DC的电流信息和发动机信息;将发动机信息输入发动机启动电流预测模型,以使发动机启动电流预测模型根据发动机信息预测发动机启动电流;根据蓄电池信息和发动机的启动次数,确定蓄电池放电电流;根据蓄电池信息中的蓄电池实际放电电流和蓄电池放电电流,确定目标蓄电池放电电流;若目标蓄电池放电电流、DC/DC的电流信息和发动机启动电流满足预设12V启动条件,触发车辆上的12V启动机,以通过12V启动机启动车辆的发动机。
