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 radar apparatus is attached to a vehicle such that a direction at 90 degrees relative to a front-rear direction of the vehicle is included in a detection range, and transmits and receives radar waves. The radar apparatus detects an observation point relative speed that is a relative speed in relation to an observation point that has reflected the radar wave within the detection range and an observation point azimuth that is an azimuth at which the observation point is present. The radar apparatus determines that a moving object is detected when an expression expressed by V

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 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.

Abstract: An image output device outputs a periphery image of a vehicle to a display; acquires a capture image of the periphery; acquires detection information of the periphery; determines an accuracy factor of detection of each object; calculates a position of the object in the capture image; determines whether objects overlap with each other in the capture image; and sets an image transmission region to at least a part of a region displaying a first object disposed on a near side among the objects determined to overlap with each other in the capture image, generates the periphery image for visually confirming a second object disposed on a far side of the first object, and changes a transmittance defined in the image transmission region higher as the accuracy factor of the detection of the second object is higher.

Abstract: An estimation apparatus of the present disclosure includes a same-object point information acquiring section, a candidate estimating section, and a direction estimating section. The candidate estimating section estimates, as a candidate direction, a direction that is matched with an arbitrary horizontal direction upon determining that the relative speeds gradually decrease along the arbitrary horizontal direction. The candidate estimating section estimates, as the candidate direction, an opposite direction of the arbitrary horizontal direction upon determining that the relative speeds gradually increases along the arbitrary horizontal direction. The direction estimating section estimates a moving direction of the same object based on the candidate direction.

Abstract: A radar apparatus generates a strength distribution indicating a correspondence relationship between a relative speed parameter related to an observation point relative speed and a reflection strength parameter related to reflection strength of radar waves reflected at an observation point, for a plurality of observation points. Furthermore, the radar apparatus determines that a traveling vehicle is detected when the reflection strength parameter decreases as the relative speed parameter increases from a center relative speed parameter that is the relative speed parameter corresponding to a peak in the reflection strength, the reflection strength parameter decreases as the relative speed parameter decreases from the center relative speed parameter, and a distribution of the reflection strength parameter is symmetrical with the center relative speed parameter at the center.

Abstract: A radar device includes a transmitting unit, a receiving unit, and a signal processor. The transmitting unit transmits a radar wave. The receiving unit mixes the received incoming wave with the radar wave to generate a beat signal. The signal processor executes a target detection process to detect a target having reflected the radar wave. In the target detection process, a signal value is extracted from the beat signal generated by the receiving unit for each of specified times, the specified time being a reciprocal of a DC component frequency, an approximation curve of a plurality of the signal values is calculated as a DC component signal, and the calculated DC component signal is subtracted from the beat signal to generate a target signal. Based on a result of frequency analysis performed on the target signal, a target that is a source of the incoming wave is detected.
