  • Publication number: 20130207833
    Abstract: 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.

  • Publication number: 20130207832
    Abstract: A vehicle-mounted radar apparatus for transmitting radar waves in a forward traveling direction of a vehicle mounting the apparatus thereon (radar-mounting vehicle) and receiving the radar waves reflected from an object to acquire information about the object. In the apparatus, a target detection unit transmits and receives the radar waves to detect positions of 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. An object position determination unit calculates a value of a predefined function of lateral positions of two or more targets of all the targets selected by the same-object target selection unit as a lateral position, along a vehicle-width direction of the radar-mounting vehicle, of the specific reflecting object.
