The invention is suitable for the technical field of automobiles, and provides an engine control method and device, a vehicle-mounted controller and a vehicle. The method comprises the steps that driving information of the vehicle and temperature information of an engine of the vehicle are obtained; if the driving information meets the first set condition and the temperature information meets the second set condition, the current battery charge state of a battery of the vehicle is obtained; according to the temperature information and the current battery charge state, the target torque range of the engine is determined; determining the target torque of the engine according to the target torque range; and controlling the engine to work under the target torque. Compared with the prior art, only when the driving information of the vehicle and the temperature information of the engine are detected to meet the set conditions, it is determined that the output torque of the engine needs to be limited, and then the final output torque of the engine can be accurately determined by combining the temperature information and the current state of charge of the battery; therefore, the control accuracy of the engine is improved, and the fuel economy of the vehicle is improved.
本申请适用于汽车技术领域,提供了一种发动机控制方法、装置、车载控制器及车辆,所述方法包括:获取车辆的驾驶信息和车辆的发动机的温度信息;若驾驶信息符合第一设定条件,且温度信息符合第二设定条件,则获取车辆的电池的当前电池荷电状态;根据温度信息和当前电池荷电状态,确定发动机的目标扭矩范围;根据目标扭矩范围,确定发动机的目标扭矩;控制发动机在目标扭矩下工作。与现有技术相比,本方法在检测到车辆的驾驶信息和发动机的温度信息均符合设定条件时,才确定发动机的输出扭矩需要限制,之后,结合上述温度信息和当前电池荷电状态可以准确确定发动机最终的输出扭矩,从而提高了对发动机的控制准确率,提高了车辆的燃油经济性。
