The invention discloses an engine torque control method and device, and the method comprises the steps: determining a required torque value of an engine according to a first mapping relation and the remaining electric quantity of a battery at the current moment within a target duration when the engine starts to work, and then controlling the engine torque according to a condition that the required torque value of the engine is greater than a first preset threshold value; according to the method, the required torque value of the engine is adjusted in time through the second mapping relation, the required torque value of the engine is adjusted to be smaller through the torque step length calibrated in an unauthorized mode, then the situation that the emission smoke intensity limit value is triggered due to the fact that the required torque value of the engine is too large can be avoided, and the fuel economy of the vehicle can be improved.

    本申请公开了一种发动机扭矩控制方法及装置,在发动机开始启动工作的目标时长内,根据第一映射关系和当前时刻电池的剩余电量确定发动机的需求扭矩值,然后针对发动机的需求扭矩值大于第一预设阈值的情况,通过第二映射关系及时调整发动机的需求扭矩值,利用越权标定的扭矩步长实现调整发动机的需求扭矩值变小,进而可以避免由于发动机的需求扭矩值过大,导致触发排放烟度限值,还可以提高车辆燃油经济性。
