  • Patent number: 11014562
    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.

  • Patent number: 10908605
    Abstract: In a driving assist system, a driving assist device as a control device acquires driving control information to be used for performing a driving control process in which an own vehicle follows a preceding vehicle running on the same lane of the own vehicle in front of the own vehicle. The driving assist device performs the driving control process of the own vehicle based on the acquired driving control information. The driving assist device detects an interruption of a preceding-vehicle following of the own vehicle. In the preceding-vehicle following, the own vehicle follows the preceding vehicle running on the same lane. The driving assist device decelerates a vehicle speed of the own vehicle by using a predetermined braking force when detecting the interruption of the preceding-vehicle following of the own vehicle during the preceding-vehicle following.

  • Patent number: 10896612
    Abstract: Disclosed herein is a lane change assistance device, including: a change time setting unit configured to set a change time required for the lane change; a yaw angle acquisition unit configured to acquire a yaw angle of an own vehicle before starting the lane change; and a steering control unit configured to control a steering unit of the own vehicle to perform the lane change in the change time set by the change time setting unit, wherein when the yaw angle acquired by the yaw angle acquisition unit is a yaw angle in a state where the own vehicle approaches a target lane designated during the lane change, the change time setting unit sets the change time shorter than in other states, and when the yaw angle acquired by the yaw angle acquisition unit is a yaw angle in a state where the own vehicle stays away from the target lane, the change time setting unit sets the change time longer than in the other states.

  • Patent number: 10843695
    Abstract: In an apparatus, a first obtainer obtains a first travelling-condition parameter of a target vehicle. The first travelling-condition parameter shows one or more conditions under which the target vehicle is travelling on the road. A second obtainer obtains a second travelling-condition parameter of a preceding vehicle travelling on the road immediately ahead of the target vehicle. The second travelling-condition parameter shows one or more conditions under which the preceding vehicle is travelling on the road. A deviation calculator calculates a deviation between the first and second travelling-condition parameters. A behavior deter miner deter mines a recommended behavior of the target vehicle in response to the calculated deviation. A controller controls a device, which is associated with a behavior of the target vehicle, according to the recommended behavior.

  • Patent number: 10745014
    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.

  • Patent number: 10661794
    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.

  • Patent number: 10538244
    Abstract: A driving assistance apparatus is mounted in an own vehicle and performs driving assistance for the own vehicle. The driving assistance apparatus determines a travel recommended lane in which the own vehicle is to travel, based on a comparison of a preset vehicle speed set in advance to allow the own vehicle to travel at a constant speed, to a travel state of a preceding vehicle traveling ahead of the own vehicle in a travel lane in which the own vehicle is traveling and a travel state of an adjacent vehicle traveling ahead of the own vehicle in an adjacent lane that is adjacent to the travel lane. The driving assistance apparatus performs output based on the travel recommended lane.

  • Publication number: 20190171896
    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.
