The invention discloses a vehicle torque determining method and system, a vehicle and a storage medium, and the vehicle torque determining method comprises the steps that operation data and the vehicle speed of the vehicle are obtained, and the operation data comprise an accelerator pedal signal, a brake pedal signal and a gear signal; a drivability factor value is determined according to the accelerator pedal signal, and the drivability factor value is used for compensating the required torque of the vehicle; determining a first demand torque according to the accelerator pedal signal, the vehicle speed, the gear signal and the drivability factor value; performing torque limiting on the first demand torque according to a preset torque limiting condition to obtain a second demand torque; and filtering the second demand torque according to a preset filtering condition to obtain a target demand torque. The technical problem that when the vehicle is in the rapid acceleration working condition, an existing conventional torque calculation method cannot accurately determine the required torque of the vehicle is solved.

    本发明公开了一种车辆扭矩的确定方法、系统、车辆及存储介质,其中,车辆扭矩的确定方法包括:获取车辆的操作数据和车速,其中,操作数据包括油门踏板信号、制动踏板信号和挡位信号;根据油门踏板信号确定驾驶性因素值,其中,驾驶性因素值用于对车辆的需求扭矩进行补偿;根据油门踏板信号、车速、挡位信号和驾驶性因素值,确定第一需求扭矩;根据预设限扭条件对第一需求扭矩进行限扭得到第二需求扭矩;根据预设滤波条件对第二需求扭矩进行滤波得到目标需求扭矩。本发明解决了车辆处于急加速工况时,现有的常规扭矩计算方法无法准确的确定车辆的需求扭矩的技术问题。
