The invention discloses an anti-skid control method and system for a four-wheel-drive electric vehicle, a medium and the four-wheel-drive electric vehicle. The method comprises the steps that whole vehicle operation information of the four-wheel-drive electric vehicle is obtained; switching an anti-slip control flag bit by utilizing the speed difference of front and rear wheels in the whole vehicle operation information; the anti-slip control flag bit comprises a first flag bit, and the first flag bit indicates entering of anti-slip control; if the anti-skid control flag bit is switched to the first flag bit, controlling the four-wheel-drive electric vehicle to enter an anti-skid control mode and calculating a front axle torque distribution ratio correction value; based on the front axle torque distribution ratio correction value, carrying out correction and limit value processing on a basic front axle torque distribution ratio under a standard working condition to obtain a target front axle torque distribution ratio; the target front axle torque distribution ratio is used for adjusting the front axle torque and the rear axle torque of the four-wheel-drive electric vehicle.
本发明公开了一种四驱电动车的防滑控制方法、系统、介质及四驱电动车,所述方法包括:获取四驱电动车的整车运行信息;利用所述整车运行信息中的前后轮车速差切换防滑控制标志位;所述防滑控制标志位包含第一标志位,所述第一标志位表示进入防滑控制;若所述防滑控制标志位切换为所述第一标志位,控制所述四驱电动车进入防滑控制模式并计算前轴扭矩分配比修正值;基于所述前轴扭矩分配比修正值,对标准工况下的基础前轴扭矩分配比进行修正以及限值处理,得到目标前轴扭矩分配比;所述目标前轴扭矩分配比用于对所述四驱电动车的前后轴扭矩进行调整。
