The embodiment of the invention provides a collision detection method, a vehicle braking method and device, a vehicle and a storage medium, and relates to the technical field of intelligent driving. The collision detection method comprises the following steps: acquiring a moving track of a target obstacle, a moving track of a vehicle, and a relative distance and a relative azimuth angle between the target obstacle and the vehicle; determining an expected collision area according to the moving trajectory of the vehicle and the moving trajectory of the target obstacle; respectively calculating first time, second time, third time and fourth time according to the relative distance and the relative azimuth angle; and according to the first time, the second time, the third time and the fourth time, determining whether there is a collision risk between the vehicle and the target obstacle, thereby analyzing the collision area of the vehicle in the crossroad section, considering the complex traffic of the crossroad section, and improving the accuracy of the collision detection result.

    本申请实施例提供一种碰撞检测方法、车辆制动方法、装置、车辆及存储介质,涉及智能驾驶技术领域。其中,碰撞检测方法通过获取目标障碍物的运行轨迹、自车的运行轨迹、目标障碍物与自车的相对距离和相对方位角;根据自车的运行轨迹和目标障碍物的运行轨迹确定预期碰撞区域;根据相对距离和相对方位角分别计算第一时间、第二时间、第三时间、第四时间;根据第一时间、第二时间、第三时间以及第四时间确定自车与目标障碍物是否存在碰撞风险,从而对车辆处于十字路口路段的碰撞区域进行了分析,考虑了十字路口路段的复杂交通,可以提升碰撞检测结果的准确性。
