A vehicle tire driving force control method under an extreme road surface working condition belongs to the technical field of vehicle control, and comprises the following steps: constructing a mechanical model of a tire and a road surface through discrete element simulation software, and simulating to obtain a relationship between longitudinal sliding force and a slip rate under different road surface soil conditions; determining a longitudinal sliding force peak point under various road surface conditions and a corresponding slip rate; the road surface type is judged, the peak point of the longitudinal sliding force serves as a tracking point, the current slip rate is changed, the maximum longitudinal sliding force is obtained when the vehicle slips or is close to slip, and the escaping and passing capacity of the vehicle is improved.

    一种极限路面工况条件下车辆轮胎驱动力控制方法,属于车辆控制技术领域,包括以下步骤:通过离散元仿真软件,构建轮胎和路面的力学模型,仿真获取不同路面土壤条件下纵滑力与滑转率之间的关系;确定各种路面条件下纵滑力峰值点及其对应的滑转率;判断路面类型,以纵滑力峰值点作为追踪点,通过改变当前滑转率,使得车辆在发生打滑或者临近打滑时获取最大纵滑力,提高车辆的脱困及通过能力。
