在研究追及和避碰问题时,通常有以下三种方法:1解析法在同一直线上,后面的物体能否追上或者碰撞前面的物体、两物体的最远或者最近距离的临界状态,通常是在它们的速度相等时。因此可以先确定临界条件,然后列出方程进行求解。例1甲乙两车同时从同一地点、同一方向出发,甲以v1=16 There are usually three ways to study the problem of tracking and collision avoidance: 1) The analytical method can determine whether the back object can catch up or collide with the front object or the critical state of the furthest distance or the closest distance between the two objects on the same straight line. It is when their speed is equal. Therefore, you can first determine the critical condition and then list the equations for solving. Example 1 A, B, and B vehicles start from the same location and in the same direction at the same time. A to v1=16
