The invention discloses a vehicle collision time determination method and device. The method comprises the steps that vehicle data of a vehicle and detection data of a target object are determined; determining a first predicted driving track of the vehicle and a second predicted driving track of the target object based on the vehicle data and the detection data; based on first driving data in the self-vehicle data, second driving data in the detection data and a second predicted driving track, determining a collision working condition; determining a plurality of trajectory intersection points based on the first predicted driving trajectory and the second predicted driving trajectory; and determining the collision time based on the self-vehicle data, the detection data, the collision working condition and the plurality of track intersection points. According to the technical scheme, the collision working condition and the multiple track intersection points are determined through the vehicle data and the detection data of the target object, and then the collision time is determined based on the collision working condition and the multiple track intersection points, so that the collision time can be accurately determined in a mode of combining different working conditions with track intersection; therefore, the prediction accuracy of the collision time is improved.

    公开了一种车辆碰撞时间的确定方法及装置,该方法包括确定自车的自车数据以及目标对象的检测数据;基于自车数据和检测数据分别确定自车的第一预测行驶轨迹和目标对象的第二预测行驶轨迹;基于自车数据中的第一行驶数据、检测数据中的第二行驶数据和第二预测行驶轨迹,确定碰撞工况;基于第一预测行驶轨迹和第二预测行驶轨迹,确定多个轨迹交叉点;基于自车数据、检测数据、碰撞工况和多个轨迹交叉点,确定碰撞时间。本公开的技术方案通过自车数据和目标对象的检测数据确定碰撞工况和多个轨迹交叉点,再基于碰撞工况和多个轨迹交车点来确定碰撞时间,如此能够以不同工况结合轨迹交叉的方式来精确地确定碰撞时间,从而提高碰撞时间的预测准确率。
