Abstract:
A risk estimation system estimates the degree of risk ahead of a vehicle. Three-dimensional object layout information indicates the three-dimensional layout of a three-dimensional object ahead of the vehicle. An intersecting road is a road that intersects a traveling road, which is a road on which the vehicle is traveling, at an intersection ahead of the vehicle. The risk estimation system sets a first area that extends from the intersection into the intersecting road by a first length. Based on the three-dimensional object layout information, the risk estimation system calculates the degree of blocking indicating a degree to which the first area is blocked by the three-dimensional object when seen from the position of the vehicle. After that, the risk estimation system calculates the degree of risk in such a way that the degree of risk increases as the degree of blocking is higher.
Abstract:
A vehicle notification apparatus recognizes an object of driving over on a road on which a host vehicle travels based on a detection result by a front sensor of the host vehicle, determines whether the object of driving over flies backwards based on a detection result by a rear sensor of the host vehicle when the object of driving over is recognized, and notifies a following vehicle of projectile information corresponding to the flight of the object of driving over when it is determined that the object of driving over flies backwards.

Abstract:
An apparatus comprises three-dimensional object detecting means for detecting a three-dimensional object in a taken image, temporarily determining means for calculating, based on parallax information, a lower end height from a road surface to a lower end of the object, for temporarily determining that the object is a ground-contacting object when the lower end height is less than or equal to a threshold, and for temporarily determining that the object is a floating object when the lower end height exceeds the threshold, and finally determining means for finally determining whether the object is a ground-contacting object or a floating object. The finally determining means finally determines that the object is a ground-contacting object at the current computation timing when the object is determined to be a ground-contacting object in at least one of the temporary determination at the current computation timing and the final determination at the previous computation timing.
Abstract:
A recognition support system for a vehicle includes an image recognition sensor including a camera configured to capture an image of a periphery of a host vehicle while alternately repeating an exposure period and a non-exposure period; an irradiation device configured to irradiate light to the periphery of the host vehicle; an object recognition unit configured to recognize an object existing in the periphery of the host vehicle by using the image recognition sensor; and a light irradiation control unit configured to, when the object recognized by the object recognition unit is an alert target object, carry out intermittent irradiation of light to the alert target object by using the irradiation device, the intermittent irradiation being carried out such that an irradiation period of light and a non-irradiation period of light are alternately repeated and the non-irradiation period overlaps with at least part of the exposure period.

Abstract:
A road surface detection device that detects a road surface region based on disparity information obtained from a captured image of an area around a vehicle that is captured by an onboard camera, includes a path estimating portion that estimates a travel path where the vehicle will travel, based on driving information of the vehicle; and a detecting portion that weights the disparity information, and detects a road surface region in the captured image based on the weighted disparity information, wherein when the detecting portion weights the disparity information, the detecting portion gives less weight to the disparity information positioned on a side away from the travel path in the captured image than to the disparity information positioned on a side near the travel path in the captured image.
