  • Publication number: 20230264689
    Abstract: A travel assistance method assists the traveling of a host vehicle using a determined route and vehicle speed. The method includes: detecting an obstacle in an adjacent lane of a travel lane in which the host vehicle travels; setting a travel range on a side of the obstacle on the host vehicle side when the obstacle is detected; setting at least one of the route and the vehicle speed such that the host vehicle does not obstruct advancing of another vehicle traveling in the adjacent lane toward the obstacle in the travel range; and executing travel assistance using the set route and/or vehicle speed.

  • Publication number: 20230221130
    Abstract: A movement assistance device guides a user to a meeting location for meeting a vehicle. The movement assistance device calculates a first required time until the vehicle arrives at the meeting location, and a plurality of routes from the user's current location to the meeting location. The movement assistance device calculates a second required time for the user to arrive at the meeting location from the user's current location for each route. The movement assistance device then determines the route associated with the second required time as a route via which the vehicle could be met on time when a second required time is the same as or shorter than the first required time. The movement assistance device then causes the communication device to output information that indicates the route or routes determined to be the route or routes via which the vehicle could be met on time.

    Abstract: A meeting support system includes a communication unit capable of communicating with a first communication terminal and a second communication terminal, and a controller configured to generate support information to be sent to the first communication terminal before the first communication terminal arrives at the destination. The controller acquires position information of the first and communication terminals, calculates first and second movement progresses based on the acquired position information of the first and second communication terminals, calculates a difference between the first and second movement progresses, generates the support information and sends the generated support information to the first communication terminal. The support information includes the calculated difference and at least one of the progresses.

  • Patent number: 11262442
    Abstract: A ghost removal method includes steps of detecting, estimating and excluding. In the detecting, a position and a relative speed of a target moving object, and a position of a surrounding stationary object are detected with radio waves. In the estimating, a position and a relative speed of a ghost by the target moving object are estimated based on the detected position and relative speed of the target moving object and the position of the surrounding stationary object. In the excluding, a detected point where the estimated position and the relative speed of the ghost are detected is excluded from a candidate detection point of a moving object which is detected with radio waves.
