  • Publication number: 20190286926
    Abstract: An external environment recognition unit recognizes a construction section ahead of a host vehicle and recognizes that one or more recognition objects express entry possible/impossible information as to whether the host vehicle can enter the construction section. If the external environment recognition unit recognizes a traffic control person who directs traffic in the construction section as the recognition object and recognizes the entry possible/impossible information that is expressed by the traffic control person, an action plan unit (or an entry determination unit) decides whether to cause the host vehicle to enter the construction section or to stop before the construction section by using preferentially the entry possible/impossible information that is expressed by the traffic control person.

  • Publication number: 20190286149
    Abstract: An action plan unit (or an avoidance action plan unit) determines whether a host vehicle needs to enter a second travel path in order to pass by an avoidance object (or a construction site) on the basis of a position of the avoidance object in a width direction and a position of a center line. If the host vehicle needs to enter the second travel path and the center line prohibits departure from a first travel path in compliance with traffic regulations, the action plan unit temporarily cancels the path departure suppression control of suppressing the departure from the first travel path among controls that comply with the traffic regulations.
