The invention relates to a vehicle drifting control method and system and a vehicle. The vehicle drifting control method comprises the steps that in response to a drifting operation instruction of a user, the whole vehicle demand torque and the state parameters of the vehicle are obtained, and the front axle torque proportion is determined according to the state parameters, and then according to the front axle torque proportion and the whole vehicle demand torque, the front axle demand torque and the rear axle demand torque are determined, and according to the front axle demand torque and the rear axle demand torque, torque control is conducted on a front axle motor and a rear axle motor. By means of the method, in the whole process that a driver drives the vehicle to execute drifting, the whole vehicle required torque and the state parameters of the vehicle can be obtained in real time, different front axle torque proportions can be determined and obtained, then the obtained front axle torque proportions are more accurate and more diversified, and therefore the method adapts to more working conditions, and the driving safety of the vehicle is improved. Torque distribution of the front shaft and the rear shaft is more reasonable, the duration time of drifting is prolonged, and the safety of drifting is improved.

    本公开涉及一种车辆漂移控制方法、系统及车辆,该车辆漂移控制方法包括:响应于用户的漂移操作指令,获取整车需求扭矩和车辆的状态参数,并根据状态参数确定前轴扭矩比例,再根据前轴扭矩比例和整车需求扭矩确定前轴需求扭矩和后轴需求扭矩,并根据前轴需求扭矩和后轴需求扭矩分别对前轴电机和后轴电机进行扭矩控制。通过上述方法,能够在驾驶员驾驶车辆执行漂移的整个过程中,实时获取车辆的整车需求扭矩以及车辆的状态参数,能够确定得到不同的前轴扭矩比例,进而使得到的前轴扭矩比例更加准确且更加多样化,从而适应更多的工况,使前后轴的扭矩分配更加合理,提高漂移的持续时间以及漂移的安全性。
