The invention discloses a vehicle, a target threat estimation method thereof and a computer storage medium. The method comprises the steps that braking delay time is acquired; main motion delay information of the main vehicle after the braking delay time and target motion delay information of the target vehicle after the braking delay time are obtained; predicting primary motion prediction information of the primary vehicle based on the primary motion delay information; predicting target motion prediction information of the target vehicle based on the target motion delay information; and obtaining transverse threat estimation information and/or longitudinal threat estimation information of the main vehicle and the target vehicle according to the main motion prediction information and the target motion prediction information. According to the vehicle, the motion information of the target vehicle and the motion information of the main vehicle are extracted, the thought of prediction is introduced without depending on other unstable external environment information, the threat evaluation indexes of the target vehicle and the main vehicle in the transverse direction and the longitudinal direction are calculated respectively, and the danger degree of the target vehicle to the main vehicle is estimated through the dynamic process parameters.

    本申请公开了一种车辆及其目标威胁估计方法、计算机存储介质,该方法包括:获取制动延迟时间;获取主车在制动延迟时间后的主运动延迟信息,以及目标车在制动延迟时间后的目标运动延迟信息;基于主运动延迟信息,预测主车的主运动预测信息;基于所述目标运动延迟信息,预测所述目标车的目标运动预测信息;按照所述主运动预测信息和所述目标运动预测信息,获取所述主车与所述目标车的横向威胁估计信息,和/或纵向威胁估计信息。本申请的车辆通过提取目标车的运动信息与主车的运动信息,不依赖于其他不稳定外部环境信息,引入预测的思想,分别计算目标车和主车在横向和纵向的威胁评价指标,通过以上动态过程参数来估计目标车对于主车的危险程度。
