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.
