Abstract
A collision judgment apparatus includes: a distance detecting unit detecting distance between a vehicle and an object; a relative speed detecting unit detecting a relative speed therebetween; a margin time calculation unit calculating a time to collision therebetween, based on the distance and the relative speed; an angle detecting unit detecting an angle of the object with respect to a running direction of the vehicle; a variation calculation unit calculating a variation of the angle over time; a setting unit setting a judgment value such that the shorter the margin time, the larger the judgment value; and a judgment unit judging that the vehicle is likely to collide with the object when the variation of the angle calculated by the variation calculation unit is lower than the judgment value set by the setting unit.
