Abstract: An object recognition device is applied to a vehicle having a range sensor that transmits a probe wave and receives the reflected wave of the probe wave. The object recognition device is configured to recognize an object behind the own vehicle based on detection information of the range sensor. The object recognition device includes a tow determining unit configured to determine whether a towed vehicle is coupled to a rear of the own vehicle, and a changing unit configured to, in response to determining that the towed vehicle is coupled to the rear of the own vehicle, change how the range sensor detects an object to suppress reception of the reflected wave caused by presence of the towed vehicle.

Abstract: An object tracking apparatus generates a plurality of target candidates in which ambiguity in velocity is assumed for an object detected for a first time, calculates a current prediction value of a state quantity of each target candidate from a past estimation value of the state quantity of each target candidate, using one filter among a plurality of filters, and calculates the current estimation value of the state quantity of the target candidate from each of the calculated prediction values and a current observation value that matches each prediction value. The object tracking apparatus deletes the target candidate of which a determined likelihood is less than a preset threshold among the target candidates, and switches a used filter to a filter that has a larger number of state variables among the filters, in response to the target candidate being deleted and the total number of target candidates decreasing.

Abstract: An object-detecting device includes a first detector, an object tracker, a second detector, and an axial misalignment determiner. The first detector detects a distance between a moving body and an object and an orientation of the object relative to the moving body based on detection information acquired from detection sensors including a search wave sensor that searches a detection region with a search wave. The object tracker tracks the same object passing through a different detection region based on the detection information. The second detector detects at least either one of a height of the object or a lateral distance of the object as object information based on the detection information. The axial misalignment determiner determines whether axial misalignment has occurred in the search wave sensor based on the distance and the orientation of the object detected by the first detector based on the detection information from the search wave sensor and the object information detected in a different detection region by the second detector.

Abstract: A vehicle information providing apparatus (hereinafter, apparatus) repeatedly acquires observation point information. The apparatus calculates at least one position of the predicted point. When the observation point information is acquired, the apparatus extracts a predicted point that can be connected to the observation point from the calculated predicted points. The apparatus calculates the position of the current filtered point based on the position of the current observation point and the position of the latest predicted point. When the observation point information of a new object (an object having no latest predicted point connectable to the observation point) is acquired, the device sets initial vectors. The apparatus calculates the position of the predicted point at time instants succeeding the current time instant for each of the traveling directions indicated by the initial vectors.

Abstract: A radar apparatus is mountable to a vehicle. The radar apparatus includes an observing unit, an estimating unit, a predicting unit, a matching processing unit, and a determining unit. The estimating unit calculates, regarding an initial detection target object, a plurality of velocity estimation values in which folding is presumed, using a velocity observation value calculated by the observing unit. The predicting unit calculates a prediction value from each of the plurality of velocity estimation values. The matching processing unit performs association of the velocity prediction value and the velocity observation value.

Abstract: An in-vehicle radar device includes a transmission section, a reception section, an analysis section, an extraction section, a speed calculation section, a distance calculation section, and a folding detection section. The folding detection section detects occurrence of erroneous calculation of a distance, when reflection intensity at a frequency peak obtained by the extraction section is smaller than a preset intensity threshold for a distance calculated by the distance calculation section and a frequency width in a frequency spectrum calculated by the analysis section is smaller than a preset width threshold.

Abstract: A driving support apparatus supports driving of the vehicle. The driving support apparatus includes a brake pedal detection unit, a retraction speed calculation unit and a driving operation device setting unit. The brake pedal detection unit detects an operation amount of the brake pedal. The retraction speed calculation unit calculates a retraction speed of the brake pedal, based on the operation amount of the brake pedal detected by the brake pedal detection unit. The driving operation device setting unit sets a reaction force exerted by a driving operation device to a larger value as the retraction speed calculated by the retraction speed calculation unit becomes higher.
