Abstract: An inter-vehicle calculation unit calculates a required inter-vehicle distance required between the own vehicle and forward/rear vehicles traveling in the lane to which the own vehicle moves during the lane change. The required inter-vehicle distance includes a first inter-vehicle distance and a second inter-vehicle distance. The first inter-vehicle distance is the distance required to allow the own vehicle or the forward/rear vehicles to adjust their velocity after the own vehicle changes lanes, and the first inter-vehicle distance is calculated by a first calculation unit. The second inter-vehicle distance is the distance required between the own vehicle and the forward/rear vehicles after the own vehicle or the forward/rear vehicles adjust their velocity, and the second inter-vehicle distance is calculated by a second calculation unit. A determination unit determines that the own vehicle can change lanes if the relative distance is equal to or greater than the required inter-vehicle distance.

Abstract: A detection unit detects one of a plurality of inter-vehicle areas as an area candidate where the own vehicle can perform lane change. A calculation unit calculates a required inter-vehicle distance which should be secured between the own vehicle and a nearby vehicle upon lane change to the area candidate. An extraction unit extracts, within preset allowable ranges, a standby time and a target speed used for estimating an estimated inter-vehicle distance as lane change conditions which are conditions for the estimated inter-vehicle distance to be equal to or more than the required inter-vehicle distance. When the lane change conditions are extracted, and a determining unit determines that lane change is possible, a setting unit sets the area candidate as the lane change area.

Abstract: A reliability calculation apparatus calculates a reliability of a recognized object that is recognized as being present on a route on which a vehicle travels. The reliability of the recognized object is used for driving control of the vehicle. In the reliability calculation apparatus, a provisional reliability calculating unit determines a feature quantity of each of a plurality of recognized objects, selects a plurality of pairs of recognized objects from the plurality of recognized objects, determines a difference in feature quantity of each pair of recognized objects, and calculates a reliability that decreases as the difference in feature quantity increases as a provisional reliability of each pair of recognized objects. An integrated reliability calculating unit calculates an integrated reliability of each recognized object from the provisional reliabilities of the plurality of pairs of recognized objects.

Abstract: A driving assistance device includes a recognition unit, a region setting unit, a travel setting unit, and a travel control unit. Based on the relative speed of a vehicle with respect to an object recognized by the recognition unit, the region setting unit sets a prohibited travel region where the vehicle is prohibited from entering around the object, and further sets a region of a travel path that excludes the prohibited travel region as a permitted travel region where the vehicle is to travel. The travel setting unit sets at least one of a target vehicle speed and a target travel trajectory of the vehicle that is to travel in the permitted travel region set by the region setting unit.
