  • Patent number: 11084492
    Abstract: An automated driving assist apparatus includes a traffic information acquirer, a traffic congestion determiner, a distance comparator, a lane-change start determiner, and a lane-change controller. When the traffic congestion determiner determines that a passing lane adjacent to a lane regulation zone is congested, the distance comparator calculates a distance to the lane regulation zone and an estimated distance to a traffic queue based on road traffic information acquired by the traffic information acquirer, and compares the distance to the lane regulation zone with the estimated distance to the traffic queue. When the distance to the lane regulation zone is longer than the estimated distance to the traffic queue, the lane-change start determiner determines whether the estimated distance to the traffic queue reaches a lane-change start distance. When the estimated distance to the traffic queue reaches the lane-change start distance, the lane-change controller causes the own vehicle to change lanes.

  • Publication number: 20210200241
    Abstract: A mobility information provision system includes a collector, a mapping unit, a generator, a controller, and an identification unit. The collector collects information about movement of mobile bodies. The mapping unit maps positions of the mobile bodies on the basis of the information collected by the collector. The generator generates course-related information by using information including the mapped positions. The controller controls movement of each of the mobile bodies, by using the generated course-related information. The identification unit identifies one or more first mobile bodies to be caused to make movement different from or to be prioritized over movement of one or more second mobile bodies, on the basis of the collected information, or the information including the mapped positions. The mapping unit assigns a tag to make the identified first mobile bodies distinguishable from the second mobile bodies, in the information including the mapped positions.

  • Publication number: 20210201684
    Abstract: A mobility information provision system includes a collector, a mapping unit, an overall generator, and a specific generator. The collector collects information about movement of a plurality of mobile bodies. The mapping unit maps positions of the plurality of mobile bodies on the basis of the information collected by the collector. The overall generator repeatedly performs a first generation process of generating course-related information by using information including the mapped positions. The specific generator performs, in a case where a specific area for one or more mobile bodies, out of the plurality of mobile bodies, has been set, a second generation process of generating the course-related information for the one or more mobile bodies present in the specific area, by using the information including the mapped positions. The specific generator executes the second generation process in precedence over the first generation process executed by the overall generator.
