The invention discloses a confidence judgment method and device for a traffic moving target, equipment and a medium. The method comprises the following steps: acquiring a transverse and longitudinal relative distance and a transverse and longitudinal relative speed; according to the difference relation between the difference of the transverse and longitudinal relative distances and the difference of the transverse and longitudinal relative speeds, a distance jump result is determined, and the distance jump confidence coefficient is determined; determining a corresponding differential relative speed according to the difference of the transverse and longitudinal relative distances of the plurality of periods, determining a speed jump result according to the difference relationship between the differential relative speed and the transverse and longitudinal relative speeds, and determining a speed jump confidence coefficient according to the relationship between the speed jump result and a speed jump threshold; according to the distance jump confidence coefficient and the speed jump confidence coefficient, the relation between the collision time between the vehicle and the forward target vehicle and a time threshold value is compared, and the confidence coefficient of the target vehicle is determined. According to the invention, the technical problem of false triggering of collision early warning or automatic emergency braking of the vehicle for the transverse moving target is solved.

    本发明公开了一种交通移动目标的置信度判断方法、装置、设备和介质,方法包括:获取横纵向相对距离和横纵向相对速度;根据横纵向相对距离的差分与横纵向相对速度的差分之间的差值关系,确定距离跳变结果,并确定距离跳变置信度;根据多个周期的横纵向相对距离的差分确定对应的差分相对速度,根据差分相对速度与横纵向相对速度之间的差值关系,确定速度跳变结果,并根据速度跳变结果与速度跳变阈值的关系,确定速度跳变置信度;根据距离跳变置信度和速度跳变置信度,比较自车与前向目标车辆之间的碰撞时间与时间阈值之间的关系,确定目标车辆的置信度。本发明解决了针对横向移动目标误触发碰撞预警或车辆自动紧急制动的技术问题。
