Abstract:
1. A vehicle-mounted radar apparatus for transmitting radar waves in a forward traveling direction 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; 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 an object position determination unit that calculates a value of a predefined function of lateral positions of two or more targets of the same-object target group as a lateral position, along a vehicle-width direction of the radar-mounting vehicle, of the specific reflecting object, a large-vehicle determination unit that determines whether or not the specific reflecting object is a large vehicle; and a first position determination inhibition unit that, when it is determined by the large-vehicle determination unit that the specific reflecting object is not a large vehicle, inhibits the object position determination unit from calculating the predefined function of lateral positions of two or more targets of the same-object target group as the lateral position of the specific reflecting object, and the object position determination unit is configured to, when inhibited by the first position determination inhibition unit from calculating the predefined function of lateral positions of two or more targets of the same-object target group as the lateral position of the specific reflecting object, determine a lateral position of the representative target as the lateral position of the specific reflecting object.
