  • Patent number: 11897455
    Abstract: A vehicle is autonomously driven in an environment where a first road for vehicles running in a first direction and a second road for vehicles running in a second direction, different from the first direction, are provided alongside each other, and where a first parking space that is entered from the first road and exited to the first road is set and a second parking space that is entered from the second road and exited to the second road is set. When the vehicle is temporarily parked in the first parking space and a running direction of the vehicle heading for the next destination after being parked is the second direction, the vehicle is transferred from the first parking space to the second parking space by autonomous driving after a user of the vehicle gets out of the vehicle.

  • Publication number: 20220388421
    Abstract: An automated valet parking system enables a plurality of charging parking frames in a parking place to be utilized and reduces inconvenience to an EV user using an automated valet parking service. The management device acquires a vehicle usage schedule and a remaining charge amount of each EV and determines a parking frame usage schedule of a charging parking frame. Specifically, with respect to an EV scheduled to be used on the next day, the management device assigns a charging parking frame closer to the departure/arrival place to an EV having earlier use start time on the next day. With respect to an EV not scheduled to be used on the next day and an EV whose usage schedule is unknown, the management device assigns a charging parking frame farther from the departure/arrival place to an EV with smaller remaining charge amount.

  • Publication number: 20220392349
    Abstract: An automated valet parking (AVP) management system manages an AVP service delivered in a predetermined area. A pick-up or drop-off point is away from a parking facility in which a vehicle is parked. When it is not possible to deliver the AVP service to a user in accordance with a user request, notification information is delivered to the user. The notification information includes at least one of: a congestion situation on a route from a current position of the vehicle to a specified pick-up or drop-off point; a congestion situation at the specified pick-up or drop-off point; a waiting time for the user to get on or off the vehicle at the specified pick-up or drop-off point; a recommended time of day of use at the specified pick-up or drop-off point; and a substitute pick-up or drop-off point being a substitute for the specified pick-up or drop-off point.

  • Publication number: 20220355790
    Abstract: In a system, a parallel-parking number that is the number of the parking spaces aligned in the parallel-parking direction is acquired for each parking area. A vacancy number that is the number of vacant parking spaces is acquired for each parking area. Based on the parallel-parking number, a vacancy number threshold value is calculated that is a threshold value of the vacancy number for calculating a priority of each parking area, in one of which an automated-parking-target vehicle is to be parked. The priorities are calculated such that the priority of a parking area with the vacancy number equal to or larger than the vacancy number threshold value is higher than the priority of a parking area with the vacancy number smaller than the vacancy number threshold value. The automated-parking-target vehicle is caused to park preferentially in a parking space in the parking area with the higher priority.
