The invention discloses a vehicle speed estimation method and system for a four-wheel independent drive vehicle, a computer readable storage medium, electronic equipment and a vehicle, and the method comprises the steps: determining a target wheel when each wheel slips; performing torque control on a target wheel to enable the target wheel to be in a non-slip state; and determining the speed of the whole vehicle based on the torque of the target wheel. According to the vehicle speed estimation method and system for the four-wheel independent drive vehicle, the computer readable storage medium, the electronic equipment and the vehicle provided by the invention, torque control is quickly and accurately performed on the target wheel by utilizing the advantage of four-motor independent drive, dependence on an acceleration sensor with relatively large signal noise is not needed, and the vehicle speed estimation efficiency is improved. And the vehicle speed of the whole vehicle can be estimated only through the stable wheel speed signal.

    本发明公开了一种用于四轮独立驱动车辆的车速估算方法、系统、计算机可读存储介质、电子设备及车辆,所述方法包括:当各个车轮均打滑时,确定目标车轮;对目标车轮进行扭矩控制,以使所述目标车轮处于非打滑状态;基于所述目标车轮的扭矩,确定车辆的整车车速。根据本发明提供的用于四轮独立驱动车辆的车速估算方法、系统、计算机可读存储介质、电子设备及车辆,利用四电机独立驱动的优势,快速准确地对目标车轮进行扭矩控制,无需依赖于信号噪声较大的加速度传感器,仅通过稳定的轮速信号即可实现整车车速估算。
