  • Patent number: 9618608
    Abstract: A target detection apparatus counts the number of reflection points, taking a reflection point of interest as being a target reflection point, for each detected reflection point, the reflection points being present in a target area that is set with reference to the target reflection point and each having a difference in speed from the target reflection point, the difference being not more than a preset identical speed determination threshold, and extracts a parallel-running pair that is a pair of the reflection points that meet preset parallel-running conditions. The target detection apparatus determines that the two reflection points configuring the parallel-running pair originate from an identical target, when a count value is not less than a preset size determination threshold, the count value being of at least either of the two reflection points configuring the extracted parallel-running pair and generates target information reflecting the determination results.

  • Patent number: 9134409
    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.

  • Patent number: 9073548
    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. 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 the object is a large vehicle on the basis of a number of targets selected by the same-object target selection unit and reflection wave received powers for the respective targets.

  • Publication number: 20150048968
    Abstract: In an in-vehicle radar apparatus, a signal processing unit calculates a change curve shape of power values of the reception power of the radio waves received by a receiving unit in relation to the distance from the own vehicle when the speed of the own vehicle acquired by a speedometer is a predetermined value or lower and the distance from the own vehicle to the target measured by a measuring unit is a predetermined value or less, and determines a portion of the change curve shape as a target to be detected. The portion indicates a local maximum value or an inflection value of the power values of which a difference in power with a maximum value is within a certain range, among local maximum values or inflection values of the power values at distances closer to the own vehicle than the maximum value of the power values.
