The invention discloses a chassis in-situ differential steering control method, device and equipment and a storage medium, and relates to the technical field of vehicle steering control, and the chassis in-situ differential steering control method comprises the steps that the first transverse distance between a front axle and a middle axle of a vehicle, the second transverse distance between the middle axle and a rear axle, the chassis wheel track and the transverse coordinate value of a theoretical steering center are obtained; the first transverse distance, the second transverse distance, the chassis wheel tread and the transverse coordinate value of the theoretical steering center are calculated, and a target steering center of chassis in-situ differential steering is obtained; the vehicle is controlled to conduct in-situ differential steering based on the target steering center, the method is suitable for a vehicle model with front, middle and rear sets of wheels arranged at equal intervals or unequal intervals in the length direction of the whole vehicle, a theoretical basis is provided for vehicle control, the analog simulation calculation checking capacity of a whole vehicle factory during vehicle model development is improved, and the vehicle model development efficiency is improved. And the differential steering of the vehicle can be more accurately controlled.

    本申请公开了一种底盘原地差速转向的控制方法、装置、设备及存储介质,涉及车辆的转向控制技术领域,包括:获取车辆的前轴与中轴的第一横向距离、中轴与后轴的第二横向距离、底盘轮距以及理论转向中心的横向坐标值;对第一横向距离、第二横向距离、底盘轮距以及理论转向中心的横向坐标值进行计算,得到底盘原地差速转向的目标转向中心;基于目标转向中心控制车辆进行原地差速转向,适用于前、中、后三组车轮在整车长度方向上等距或不等距布置方式的车型,对车辆的控制提供了理论依据,提升了整车厂在进行车型开发时的模拟仿真计算校核能力,更精准的控制车辆进行差速转向。
