Collision judgment apparatus for vehicle
First Claim
1. A collision judgment apparatus for a vehicle, comprising:
- a position information acquiring unit which acquires position information of an obstacle positioned in a traveling direction of the vehicle based on a received signal obtained by transmitting an electromagnetic wave from the vehicle to the obstacle and receiving a reflected wave from the obstacle;
a collision judging unit which judges collision between the vehicle and the obstacle based on a relative positional relationship between a subject vehicle position of the vehicle and a relative movement straight line of the obstacle with respect to the vehicle as calculated based on a plurality of pieces of the position information acquired by the position information acquiring unit in relation to the obstacle;
a curve judging unit which judges a curved state of a cruising road on which the vehicle travels; and
an adjusting unit which adjusts the relative positional relationship between the relative movement straight line and the subject vehicle position so that a distance between the relative movement straight line and the subject vehicle position is more separated in a widthwise direction of the vehicle if it is judged by the curve judging unit that the vehicle is entering an entrance to a curve as compared with a situation in which the vehicle is not entering the entrance to the curve when collision judgment is performed by the collision judging unit.

Abstract
A correct collision judgment is realized between an obstacle and a vehicle even when the vehicle enters a curve. In a collision judgment apparatus for judging the collision between the vehicle and the obstacle based on a relative positional relationship between a subject vehicle position of the vehicle and a relative movement straight line of the obstacle with respect to the vehicle as calculated based on a plurality of pieces of the position information acquired by a position information acquiring unit in relation to the obstacle, the relative positional relationship between the relative movement straight line and the subject vehicle position is adjusted so that a distance between the relative movement straight line and the subject vehicle position is separated if it is judged that the vehicle enters an entrance to a curve as compared with a situation in which the vehicle does not enter the entrance to the curve.
