Abstract: The driving support system detects an object existing around an own vehicle. The driving support system 1 predicts a position of a movement destination of the detected object. The driving support system sets a region having a predetermined width at each of an X coordinate and a Y coordinate as a tracking region to be set for tracking the object, based on an XY coordinate of the position of the predicted movement destination of the object. The driving support system limits the tracking region, based on a tracking exclusion region where objects unsuitable as tracking targets may be detected with high probability. At that time, the driving support system limits the tracking region by excluding the tracking exclusion region from the tracking region.

Abstract: An intersecting road estimation device includes an object detection unit that detects an object existing around an own vehicle and a position of the object, an object extraction unit that extracts a stationary object and a position of the stationary object from an object detection result, a first estimation unit that estimates a road edge of a traveling road on which the own vehicle is traveling based on the position of the stationary object, a candidate extraction unit that extracts a stationary object existing outside the road edge of the traveling road estimated by the first estimation unit as a candidate for an outside stationary object representing a road edge of an intersecting road intersecting the traveling road, and a second estimation unit that estimates the road edge of the intersecting road based on a position of the outside stationary object extracted by the candidate extraction unit.

Abstract: A vehicle information providing 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: An executing unit is configured to execute at least one of control of operating performance of a plurality of sensors which monitor different regions around a vehicle and predetermined processing for each of a plurality of output values output from the plurality of sensors. A specifying unit is configured to specify a direction of the vehicle with respect to a reference direction set on the basis of a road around the vehicle. A setting unit is configured to set priorities of the plurality of sensors in accordance with the direction of the vehicle specified by the specifying unit. The executing unit changes at least one of ratios of the operating performance of the plurality of sensors and ratios of amounts of processing performed for the plurality of output values on the basis of the priorities.

Abstract: A dual-frequency CW processing unit (12) calculates an observation-point orientation of an observation point. An FMCW processing unit (11) calculates at least a power spectrum of a beat signal, which has been generated based on radar waves that have come from the calculated observation-point orientation, in terms of an up-modulation time interval and a down-modulation time interval (termed orientation power spectrum hereinafter). The FMCW processing unit (11) shifts the orientation power spectra of the up- and down-modulation time intervals to positive and negative directions, respectively, by an amount corresponding to a Doppler shift frequency. The FMCW processing unit (11) calculates a differential power spectrum by differentiating the orientation power spectra of the shifted up- and down-modulation time intervals, and detects a peak frequency where intensity is maximum.
