The invention discloses a collision detection method and device for an intelligent driving vehicle. The method comprises the steps of determining a target area of the intelligent driving vehicle in a scene based on position information of the intelligent driving vehicle and map information of the scene where the intelligent driving vehicle is located, and determining a target collision scene corresponding to the target area based on the target area, obtaining a safe vehicle distance between the two intelligent driving vehicles by respectively utilizing the first vehicle speed, the first braking deceleration, the second vehicle speed and the second braking deceleration of the first intelligent driving vehicle and the second intelligent driving vehicle in the target area; the safety time is obtained by using the first position information, the first attitude information and the first angular velocity information of the projection of the intelligent driving vehicle at the first moment and the second position information, the second attitude information and the second angular velocity information of the projection of other equipment at the first moment, and the early warning information is generated according to the safety vehicle distance and the safety time. The manpower cost is reduced in the driving process of the intelligent driving vehicle.
本申请公开了一种智能驾驶车辆的碰撞检测方法和装置。该方法包括基于智能驾驶车辆的位置信息,以及智能驾驶车辆所处场景的地图信息,确定智能驾驶车辆在场景中的目标区域,基于目标区域,确定与目标区域对应的目标碰撞场景,分别利用第一智能驾驶车辆和第二智能驾驶车辆在目标区域内的第一车速、第一制动减速度、第二车速和第二制动减速度,得到两个智能驾驶车辆之间的安全车距,利用智能驾驶车辆在第一时刻的投影的第一位置信息、第一姿态信息和第一角速度信息,以及其他设备在第一时刻的投影的第二位置信息、第二姿态信息和第二角速度信息,得到安全时间,根据安全车距和安全时间,生成预警信息。以实现在智能驾驶车辆驾驶过程中降低人力成本。
