The invention provides a vehicle torque control method and device, electronic equipment and a storage medium, the vehicle torque control method and device are applied to a hybrid power vehicle comprising an engine, a power battery and at least two driving motors, and the method comprises the steps that vehicle state parameters, the wheel track of the vehicle and the pre-distributed torque of the power battery are obtained; distributing the pre-distribution torque into a first distribution torque and a second distribution torque based on a preset distribution coefficient; if the vehicle state parameters meet the preset conditions, it is determined that the front wheels are passing the convex road condition; determining a time window for the rear wheels to wait for passing the convex road condition based on the driving speed and the wheel track; in the time window, the first distribution torque is controlled to be transferred to a second driving motor; if the rear wheel is passing through the convex road condition, in the time window, the first distribution torque and the second distribution torque of the second driving motor are controlled to be transferred to the first driving motor; when the vehicle passes through a convex road condition, the driving torque of the front wheel or the rear wheel is increased, the slip rate of the rear wheel is reduced, and the vehicle keeps smooth.

    本申请提供了一种车辆扭矩的控制方法、装置、电子设备及存储介质,应用于包括发动机、动力电池及至少两个驱动电机的混合动力车辆,方法包括:获取车辆状态参数、车辆的轮距及动力电池的预分配扭矩;基于预设分配系数将预分配扭矩分配为第一分配扭矩和第二分配扭矩;若车辆状态参数满足预设条件,确定前轮正在通过凸面路况;基于行驶车速和轮距,确定后轮等待通过凸面路况的时间窗口;在时间窗口内,控制第一分配扭矩转移至第二驱动电机;若后轮正在通过凸面路况,在时间窗口内,控制第二驱动电机的第一分配扭矩和第二分配扭矩均转移至第一驱动电机;在车辆通过凸面路况时,增加前轮或后轮的驱动扭矩,降低后轮的滑移率,车辆保持平顺性。
