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.

Abstract: An estimation device includes an information acquisition unit, a detection determination unit, a direction determination unit, and a direction estimation unit. When an object is a first-time detected object, the direction determination unit determines whether a relative direction acquired by the information acquisition unit is a direction toward an own vehicle. When the relative direction acquired by the information acquisition unit is a direction toward the own vehicle, the direction estimation unit estimates that a direction predetermined according to an object position acquired by the information acquisition unit is the movement direction of the object.

Abstract: An information processing device for a vehicle includes an observed value detection unit, a tracking unit, and an abnormality determination unit. The abnormality determination unit determines whether a vehicle speed abnormality has occurred. If it is determined that no vehicle speed abnormality has occurred, the tracking unit performs a first process using a predicted value of a relative speed based on a detection result of a vehicle speed to calculate a current estimated value. If it is determined that the vehicle speed abnormality has occurred, the tracking unit performs a second process different from the first process to calculate the current estimated value.

Abstract: A signal processing apparatus is mounted in a moving body and performs a process for measuring an object present in a vicinity of the moving body. The apparatus sets an intensity threshold corresponding to an intensity distribution based on at least one measurement signal periodically generated, and extracts at least one target peak that is a peak that is greater than the intensity threshold in the intensity distribution, using an upper limit number set in advance as an upper limit. The apparatus stores, in a storage unit, the number of extracted peaks that is the number of the at least one target peak extracted, and sets the intensity threshold so as to suppress the number of the at least one target peak in a new intensity distribution from exceeding the upper limit number, based on the number of extracted peaks in a previous intensity distribution stored in the storage unit.

Abstract: In a target tracking device, a state quantity estimation unit is configured to, every time a preset repetition period of a processing cycle elapses, estimate, for each of the one or more targets, a current state quantity based on at least either observation information of the one or more targets observed by a sensor or past state quantities of the one or more targets. A model selection unit is configured to, for each of the one or more targets, select one motion model from a plurality of predefined motion models, based on at least either states of the one or more targets or a state of the vehicle. An estimation selection unit is configured to, for each of the one or more targets, cause the state quantity estimation unit to estimate the state quantity of the target with the one motion model selected by the model selection unit.

Abstract: An imaging optical system of a present disclosure includes, in a sequential order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. The fourth lens is configured such that (i) the light output surface has an aspherical concave shape, (ii) the light output surface has a center portion through which an optical axis passes, and a periphery thereof, and (iii) the light output surface has a portion where the negative refractive power becomes gradually weaker from the center portion toward the periphery thereof. The fifth lens has positive refractive power, a light input surface that faces toward the object side, and a light output surface that faces toward the image side. Each of the light input and output surfaces has a convex shape toward a corresponding one of the object side and image side.

Abstract: A moving object recognition apparatus includes an object detection section, a position detection section, a road direction estimation section, and a moving direction estimation section. The object detection section detects a moving object that moves on a road around an own vehicle and a roadside object by the road, from objects present around the own vehicle. The position detection section detects positions of the moving object and the roadside object detected by the object detection section. The road direction estimation section estimates a road direction of the road on which the moving object is moving, based on the position of the roadside object detected by the position detection section. The moving direction estimation section estimates a moving direction of the moving object based on the road direction estimated by the road direction estimation section.

Abstract: An object detection apparatus detects a target object present in a periphery of a moving body. The object detection apparatus derives recognition information indicating a state of a target object, and predicts a state of the target object at a next second observation timing, based on the recognition information derived at a first observation timing. The object detection apparatus derives a score based on a degree of difference between a state of the target object observed at the second observation timing and a next state of the target object predicted at the first observation timing. The object detection apparatus derives a reliability level by statistically processing scores related to the target object derived at a plurality of observation timings from past to present. In response to the reliability level satisfying a predetermined reference, the object detection apparatus determines that the target object related to the reliability level is actually present.
