The invention provides an engine torque control method and system, a storage medium and a vehicle, the method is applied to a hybrid vehicle, the method comprises the steps that a running condition distribution diagram of the vehicle under different working conditions is obtained, and the running condition diagram represents the distribution trend of engine torque and engine rotating speed under different accelerator opening degrees; based on the operation condition distribution diagram, multiple sets of engine torques under different accelerator opening degrees and different engine rotating speeds are obtained; based on the multiple sets of engine torques, multiple sets of target demand torques of the vehicle are determined; based on the multiple sets of target demand torques, a torque control boundary line under the corresponding working condition is established; and according to the torque control boundary line, the vehicle under the corresponding working condition is controlled to adjust the current engine torque. Through the method provided by the invention, the problem that the hums in the hybrid vehicle are obvious under the working conditions of low SOC, small and medium accelerator and medium and low vehicle speed is solved.

    本申请提供了一种发动机扭矩控制方法、系统、存储介质及车辆,应用于混动车辆,所述方法包括:获取车辆在不同工况下的运行工况分布图,所述运行工况图表征为在不同油门开度下的发动机扭矩和发动机转速的分布趋势;基于所述运行工况分布图,得到不同油门开度、不同所述发动机转速下的多组所述发动机扭矩;基于多组所述发动机扭矩,确定所述车辆的多组目标需求扭矩;基于多组所述目标需求扭矩,建立对应工况下的扭矩控制边界线;根据所述扭矩控制边界线,控制处于对应工况下的所述车辆调整当前的发动机扭矩。通过本发明提供的方法,解决了混动车辆在低SOC、中小油门和中低车速的工况下,车内存在嗡嗡声明显的问题。
