  • Patent number: 11790660
    Abstract: An object recognition device is configured to: classify, under a state in which not all object data in a detection data group have been received and a part of the object data have been received by a current processing time, the part of the object data into pieces regarded as ready for association determination and pieces not regarded as ready for the association determination, to thereby associate the object data regarded as ready for the association determination and the prediction data individually with each other and set, as pending object data, the object data not regarded as ready for the association determination; and associate, under a state in which the remaining object data in the detection data group have been received by the next processing time after the current processing time, the remaining object data and the pending object data individually with the prediction data.

  • Patent number: 11615627
    Abstract: There are provided an object recognition apparatus that raises the recognition accuracy for a surrounding object and a vehicle control apparatus, and an object recognition method and a vehicle control method. An object recognition apparatus receives object data, which is a state value of the object, from a first sensor for detecting a surrounding object; compares estimation data obtained through estimation of a state value of the object, based on recognition data calculated in a past period, with the object data, and determines whether or not the object data is data in a low-resolution state; then, in accordance with the determination result, calculates the state value of the object by use of object data and estimation data and then generates the state value as recognition data, so that the recognition accuracy for an object is raised.

  • Patent number: 10203406
    Abstract: The FMCW radar device includes: a range observation period setting section configured to set a plurality of range observation periods; a modulated frequency width setting section configured to set, for the respective plurality of range observation periods, a plurality of modulated frequency widths; a beat signal generation section configured to generate, for the respective plurality of range observation periods, beat signals based on the transmission signal and the reception signal; and a pass bandwidth setting section configured to set pass bandwidths of the beat signals generated by the beat signal generation section, in which the modulated frequency width setting section sets, for the respective plurality of range observation periods, the plurality of modulated frequency widths so that a difference among maximum frequencies of the beat signals generated for the respective plurality of range observation periods becomes zero or falls within a predetermined range.

  • Patent number: 7804444
    Abstract: An in-vehicle radar system, which transmits an electric wave toward a target object and measures the distance between a subject vehicle and the target object, based on the electric wave that has been reflected by the target object and is received by the in-vehicle radar system, includes subject vehicle-speed determination means for determining whether or not the subject vehicle is in a halt state or moving at a predetermined speed or lower; transmission-output control means for setting transmission output smaller than that for the case where the subject vehicle is moving, when the subject vehicle-speed determination means detects that the subject vehicle is in a halt state or moving at the predetermined speed or lower; and reception-sensitivity control means for setting a reception gain amount larger than that for the case where the subject vehicle is moving.
