The invention discloses an automobile, a radius and road trafficability determination method and device, equipment and a medium. The method for determining the turning radius of the full trailer comprises the steps that the maximum constraint value of the front wheel deflection angle of the tractor is determined on the basis of the first distance, the first wheelbase and the second distance of all full trailer buckets and the second wheelbase and the maximum allowable value of the front wheel deflection angle of the tractor; the first distance is the distance from a connecting point of the front adjacent vehicle body to the central point of the front axle; the second distance is the distance from the central point of the rear axle to the connecting point between the rear axle and the adjacent rear vehicle body; the maximum constraint value of the front wheel deflection angle is the maximum value of the front wheel deflection angle when the full trailer train is in a relative motion stable state; and determining the minimum turning radius of the rear axle of any vehicle body based on the second axle distance, the maximum constraint value of the front wheel deflection angle, the first distance of each full-trailer, the first axle distance and the second distance. In this way, the accuracy of the minimum turning radius of a full trailer train mounted with a plurality of full trailer trailers in an actual application scene is improved.

    本申请公开了一种汽车、半径和道路通过性确定方法、装置、设备和介质。全挂汽车列车的转弯半径确定方法包括:基于各全挂拖斗的第一距离、第一轴距和第二距离、以及牵引车的第二轴距和前轮偏角最大允许值,确定牵引车的前轮偏角最大约束值;第一距离为与前一相邻车体之间的联结点到前轴中心点的距离;第二距离为后轴中心点到与后一相邻车体之间的联结点的距离;前轮偏角最大约束值为全挂汽车列车处于相对运动稳定状态时的前轮偏角最大值;基于第二轴距、前轮偏角最大约束值、以及各全挂拖斗的第一距离、第一轴距和第二距离,确定任一车体的后轴最小转弯半径。如此,提高了实际应用场景下挂载多个全挂拖斗的全挂汽车列车的最小转弯半径的准确性。
