The invention is suitable for the technical field of automobiles, and provides a torque adjusting method and device of a vehicle engine, a vehicle-mounted controller and a computer readable storage medium. Acquiring system efficiency of a driving system of the vehicle and an initial torque value of an engine; determining a torque adjustment value of the engine according to the power operation mode, the system efficiency and the initial torque value; and adjusting the torque of the engine according to the torque adjustment value. Compared with the prior art that the torque of the engine is simply adjusted to the torque value corresponding to the position near the optimal fuel consumption curve, the method provided by the invention needs to be combined with the power operation mode of the vehicle, the system efficiency of the driving system and the initial torque value of the engine to determine the torque adjustment value; and the torque adjustment accuracy of the engine is improved.

    本申请适用于汽车技术领域,提供了一种车辆发动机的扭矩调整方法、装置、车载控制器及计算机可读存储介质,所述方法包括:确定车辆的动力运行模式;获取车辆的驱动系统的系统效率以及发动机的初始扭矩值;根据动力运行模式、系统效率以及初始扭矩值,确定发动机的扭矩调整值;根据扭矩调整值对发动机的扭矩进行调整。与现有技术只是简单的将发动机的扭矩调整至与最佳燃油消耗曲线附近对应的扭矩值相比,本申请提供的方法需要结合车辆的动力运行模式、驱动系统的系统效率以及发动机的初始扭矩值确定扭矩调整值,提高了发动机的扭矩调整的准确率。
