Vechicle-mounted radar apparatus

摘要

A vehicle-mounted radar apparatus for transmitting radar waves toward the outside of a vehicle mounting the apparatus thereon and receiving the radar waves reflected from an object to thereby acquire information about the object. In the apparatus, a target detection unit transmits and receives the radar waves to detect positions of targets. An object position determination unit determines a position of the object reflecting the radar waves on the basis of the positions of the targets. A representative target selection unit selects a representative target from the targets detected by the target detection unit. A same-object target selection unit selects targets belonging to the same object as the representative target. A large-vehicle determination unit determines whether or not an extent of the targets selected by the same-object target selection unit is equal to or greater than a predetermined threshold value for large-vehicle determination.

1. A vehicle-mounted radar apparatus for transmitting radar waves toward the outside of a vehicle mounting the apparatus thereon, the vehicle being hereinafter referred to as a radar-mounting vehicle, and receiving the radar waves reflected from an object to acquire information about the object, the apparatus comprising:
a target detection unit that transmits and receives the radar waves to detect positions of targets reflecting the radar waves; an object position determination unit that determines a position of the object reflecting the radar waves on the basis of the positions of the targets detected by the target detection unit; a representative target selection unit that selects one of the targets detected by the target detection unit that fulfills a predetermined representative-target designation condition for designating a representative of the targets detected by the target detection unit; a same-object target selection unit that selects, from the targets detected by the target detection unit, targets that fulfill a predetermined same-object target selection condition for determining which of the targets detected by the target detection unit belongs to the same object as the representative target, the representative target and the targets selected by the same-object target selection unit other than the representative target forming together a same-object target group, and the object that each target of the same-object target group belongs to being referred to as a specific reflecting object; and a large-vehicle determination unit that determines whether or not an extent of the targets of the same-object group is equal to or greater than a predetermined threshold value for large-vehicle determination, and when it is determined that the extent of the targets of the same-object group is equal to or greater than the predetermined threshold value for large-vehicle determination, determines that the specific reflecting object is a large vehicle.
