Abstract: In an evacuation travelling assistance apparatus, a risk determining unit determines, when a driver is not in a state capable of appropriately performing driving operations, a risk involved in stopping at a location and a risk involved in passing through the location, for each of a plurality of locations that may serve as an advancing destination of the own vehicle, based on map information, own vehicle information, and peripheral environment information. The risk determining unit evaluates, for each of the plurality of locations, at least one evaluation subject among a plurality of evaluation subject including: a risk occurrence frequency at the location; a risk avoidability at the location; and a level of danger of the risk occurring at the location, based on a plurality of levels, and determines the risk involved in stopping at each location and the risk involved in passing through each location, based on evaluation results.

Abstract: An in-vehicle system as a road curvature detection device calculates a curvature of a road in front of a vehicle based on an acquired front scene image. The in-vehicle system receives gradient information from the data map. The gradient information corresponds to a current road section on the road on which the vehicle drives. The in-vehicle system detects a gradient accuracy of the received gradient information. When the current road section has a gradient, i.e. the road is an uphill or downhill road, the in-vehicle system selects an appropriate special detection methods based on the gradient accuracy of the received gradient information, and calculates a road curvature by using the selected special detection method. Each of the special detection methods calculates a road curvature while effectively suppressing influence of a road gradient indicated by the received gradient information.

Abstract: In an apparatus for recognizing a lane partition line, a pre-branch section setting unit sets a pre-branch section of a road on which an own vehicle is traveling. The pre-branch section extends a section length from a start line that is positioned closer to the own vehicle than a branch location by an offset distance in a traveling direction of the own vehicle. A determination unit determines whether or not a geographical location of the own vehicle is within the pre-branch section. If it is determined that the geographical location of the own vehicle is within the pre-branch section, a recognition unit suppresses recognition of the lane partition line on an diverging road side of the road on which the own vehicle is traveling. The diverging road is another road branching off from the road on which the vehicle is traveling at the branch location.

Abstract: In an evacuation travelling assistance apparatus, a risk determining unit determines, when a driver is not in a state capable of appropriately performing driving operations, a risk involved in stopping at a location and a risk involved in passing through the location, for each of a plurality of locations that may serve as an advancing destination of the own vehicle, based on map information, own vehicle information, and peripheral environment information. An evacuation destination setting unit sets a location at which the risk involved in stopping at the location is lower than a predetermined reference as an evacuation destination, based on the determined risk. An evacuation route setting unit combines locations at which the risk involved in passing through the location is lower than a predetermined reference, based on the determined risk, and sets an evacuation route from the current position of the own vehicle to the evacuation destination.

Abstract: A position identifying apparatus includes a position detecting unit; an information acquiring unit; a feature extracting unit; an index value calculating unit; a feature selecting unit; a correlating unit; a weight setting unit; and a correcting unit. The position detecting unit performs a map matching to detect a vehicle position on a map. The information acquiring unit acquires road information from the map. The feature extracting unit extracts features of a ground object. The index value calculating unit calculates an index value representing a likelihood of a stationary object. The feature selecting unit selects feature candidates among the features having the index values larger than or equal to a predetermined likelihood of the stationary object. The correlating unit correlates the feature candidates with the road information. The weight setting unit sets weights of the feature candidates. The correcting unit corrects the position of the vehicle using the weights.

Abstract: In a location estimation device, a change detection unit detects a point of change in the width of a roadside structure as a width change point. A width correction unit calculates a width deviation between a first relative location of the roadside structure on a map data segment and a second relative location of the roadside structure obtained based on shape information of the roadside structure in the width direction of a vehicle. The width correction unit corrects, as a function of the width deviation and a positional accuracy of the vehicle in the travelling direction, an estimated location of the vehicle in the width direction when it is determined that there is the point of change in the width of the roadside structure in the travelling direction of the vehicle.

Abstract: In an apparatus for recognizing a location of an own vehicle, a detector is configured to detect one or more own-vehicle location candidates on roads based on map data. A partition line determiner is configured to, based on a captured image of a road around the own vehicle, determine a line type of each of partition lines extending along edges of the road. A determiner is configured to, for each of the one or more own-vehicle location candidates, under assumption that the own vehicle is at the own-vehicle location candidate, if the own vehicle is passing an intersection, determine, based on the line type of each of partition lines, a degree of confidence indicative of a likelihood that the own-vehicle location candidate at which it is assumed that the own vehicle is present is a location of the own vehicle.
