The invention relates to the technical field of new energy vehicles, and particularly discloses a turning auxiliary control method and device of a vehicle, the vehicle and a storage medium, and the method comprises the steps that under the condition that a turning auxiliary mode is started, first state information of the vehicle is obtained, and whether the turning auxiliary mode is activated or not is judged based on the first state information; if yes, control information is generated to control a brake to brake and lock rear wheels on the outer side, and target turning speed information and steering wheel turning angle information are obtained; determining front and rear axle target torque information of the vehicle based on the target turning speed information and the steering wheel angle information; the target torque information of the front and rear shafts is corrected according to the yaw velocity and then fed back to front and rear electric drive assemblies of the vehicle to achieve vehicle turning auxiliary control; the second state information of the vehicle is obtained every second time, whether the turning auxiliary mode is quitted or not is judged based on the second state information, the turning radius is smaller, the stability of the vehicle in the turning process is better, and meanwhile the method can adapt to different road conditions.

    本申请涉及新能源车辆技术领域,具体公开了一种车辆的转弯辅助控制方法、装置、车辆及存储介质,方法包括开启转弯辅助模式情况下,获取车辆的第一状态信息,基于第一状态信息判断是否激活转弯辅助模式;若激活,生成控制信息以控制制动器制动锁死外侧后轮,并获取目标转弯车速信息和方向盘转角信息;基于目标转弯车速信息以及方向盘转角信息,确定车辆的前后轴目标扭矩信息;根据横摆角速度对前后轴目标扭矩信息进行修正后,并反馈至车辆的前后电驱总成实现车辆转弯辅助控制;每隔第二时间获取车辆的第二状态信息,基于第二状态信息判断是否退出转弯辅助模式,该方法转弯半径更小,转弯过程车辆稳定性更好,同时可以适应不同的路面情况。
