  • Patent number: 10990108
    Abstract: A vehicle control system includes a vehicle-mounted sensor, a map database, a control rule database, and an electronic control unit. The electronic control unit is configured to recognize the position of a vehicle on a map; control traveling of the vehicle by using one of a plurality of control rules based on the position of the vehicle on the map, map information, and a detection result of the vehicle-mounted sensor; recognize a road section in the traveling direction of the vehicle based on the position of the vehicle on the map and the map information; specify a control rule used in the road section based on the recognized road section and control rule data; and control traveling of the vehicle in the road section by using the specified control rule.
    Type: Grant

  • Patent number: 10019017
    Abstract: An autonomous driving system includes a positioning unit that measures a position of a vehicle; a database that stores map information; an actuator that controls traveling of the vehicle; and an electronic controller configured to process: a detection of a first vehicle position and the map information; an identification of a traveling scene based on the first vehicle position and the map information; a detection of a second vehicle position by preforming position detection processing; and a control of the actuator based on the second vehicle position if a distance between the first vehicle position and the second vehicle position is equal to or smaller than a threshold or a control of the actuator based on the first vehicle position if the distance is not equal to or smaller than the threshold.
