  • Patent number: 10359293
    Abstract: The travel route calculation device includes a travel route calculation unit configured to calculate a travel route for a subject vehicle to arrive at a destination, an information acquisition unit configured to acquire information on an object, which affects recognition of a feature by the subject vehicle, as object information, and a distance measurement unit configured to measure a distance from the subject vehicle to the feature as a necessary recognition distance. The necessary recognition distance is necessary for the subject vehicle to recognize the feature when deciding an action. The travel route calculation device further includes a determination unit configured to determine difficulty in recognizing the feature, on the basis of the object information and the necessary recognition distance. The travel route calculation unit calculates the travel route while avoiding a location at which recognition of the feature is determined to be difficult by the determination unit.

  • Patent number: 10239539
    Abstract: A pedestrian crosswalk through which a subject vehicle is expected to pass is specified as a first pedestrian crosswalk and another pedestrian crosswalk located within a predetermined distance from the first pedestrian crosswalk is specified as a second pedestrian crosswalk. An extension process of extending an area of at least one of the first pedestrian crosswalk and the second pedestrian crosswalk is performed. When a determination is made that at least a part of the first pedestrian crosswalk and the second pedestrian crosswalk overlap each other, an area including the first pedestrian crosswalk and the second pedestrian crosswalk is set as a detection area of a detector detecting an object around the subject vehicle. A moving object is detected in the detection area using the detector. Travel of the subject vehicle is controlled on the basis of a detection result of the detector.

  • Patent number: 9865162
    Abstract: A control method allows an own vehicle to proceed through a specific intersection into which vehicles are permitted to proceed in the order that the vehicles arrive. The method includes setting a determination region within a lane other than a lane in which the own vehicle travels; determining whether the own vehicle reaches a certain position at the near side of the specific intersection; allocating a priority state to the determination region when the own vehicle reaches the certain position and allocating a non-priority state to the determination region in which the vehicle does not exist when the own vehicle reaches the certain position; changing the priority state of the determination region to the non-priority state when the vehicle no longer exists in the determination region; and allowing the own vehicle to proceed into the specific intersection when the determination region of the priority state is not present.
