The invention discloses a vehicle drift control method, device and equipment and a vehicle. The method comprises the steps that expected vehicle state information input by a driver and an expected vehicle body side slip angle corresponding to the expected vehicle state information are collected; and determining the expected vehicle state information as a drifting state, solving the expected vehicle body side slip angle and the arc tangent value of the vehicle state information, and obtaining the expected rear axle side slip angle of the vehicle. According to the method, the expected sideslip angle of the rear axle of the vehicle can be controlled by controlling the rotation of the rear wheels, so that the expected sideslip angle of the rear axle of the vehicle can be controlled according to the rigid body motion model, and the accurate control of the sideslip angle of the vehicle is realized. And the possibility of safety accidents caused by slip rate change of the vehicle in the drifting stage is reduced, so that the drifting risk of the vehicle is reduced, and the drifting safety of the vehicle is improved.

    本申请公开了一种车辆漂移控制方法、装置、设备及车辆,包括:采集驾驶员输入的期望车辆状态信息以及与期望车辆状态信息对应的期望车身侧偏角;确定期望车辆状态信息为漂移状态,求解期望车身侧偏角和车辆状态信息的反正切值,得到车辆的后轴期望侧滑角。上述中,控制车辆的后轴期望侧滑角可以通过控制后轮的转动来实现,由此使得车辆可以因控制了后轴期望车偏角,而根据刚体运动模型控制车辆保持在期望车身侧偏角,从而实现了对车辆的车身侧偏角的精确控制。减少了车辆在漂移阶段滑移率变化而造成安全事故的可能,从而降低了车辆漂移的危险性,提高了车辆漂移的安全性。
