The invention provides a vehicle engine torque control method and device and a storage medium. According to the method, danger and operability analysis is conducted on the torque control function of the vehicle through two paths of obtained accelerator pedal signals and engine rotating speed signals of the vehicle so as to determine the fault source of the vehicle, and after abnormal information is determined according to the fault source of the vehicle, the vehicle running mode is determined according to the abnormal information and the engine rotating speed signals, the vehicle running modes comprise multiple different limping modes, torque control is carried out on the vehicle based on the different limping modes and the pedal output opening degree, therefore, abnormal information is obtained through danger and operability analysis, torque output for different faults is achieved by setting the corresponding running modes, and the reliability of the vehicle is improved. The situation that torque output of the vehicle is controlled only according to the opening degree of the accelerator pedal is avoided, and therefore the overall safety of the vehicle is improved.

    本申请提供一种车辆的发动机扭矩控制方法、装置及存储介质。该方法通过获取的两路加速踏板信号和车辆的发动机转速信号,对车辆的扭矩控制功能进行危险与可操作性分析,以确定车辆的故障来源,并根据车辆的故障来源确定异常信息后,根据异常信息和发动机转速信号确定车辆行驶模式,其中,车辆行驶模式包括多种不同的跛行模式,基于不同的跛行模式和踏板输出开度对车辆进行扭矩控制,因此通过危险与可操作性分析获取异常信息,并且通过设置对应的行驶模式,实现对不同故障的扭矩输出,避免了仅根据加速踏板开度控制车辆的扭矩输出,从而提高了车辆的整体安全性。
