  • Publication number: 20250118201
    Abstract: A vehicle identification method for identifying a target vehicle includes the following first to sixth steps. The first step is, in a management system, generating information indicating a second action from information indicating a first action using a first key. The second step is transmitting the information indicating the second action from the management system to the target vehicle. The third step is, in the target vehicle, restoring the information indicating the first action from the information indicating the second action using a second key. The fourth step is causing the target vehicle to perform the first action. The fifth step is, in the management system, detecting an action performed by a vehicle. The sixth step is, in the management system, identifying the vehicle performing the first action as the target vehicle and not identifying the vehicle performing the second action as the target vehicle.

  • Patent number: 12122361
    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.

  • Patent number: 12115876
    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.

  • Patent number: 12100302
    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: 20240300474
    Abstract: The present disclosure provides a hybrid vehicle control system for controlling a vehicle having a motor and an engine. The system executes the following processes. The first process is determining whether a situation which the vehicle is currently facing is a situation in which high accuracy is required for control of driving of the vehicle or not. The second process is selecting only an EV mode under a situation in which high accuracy is required for the control. The third process is selecting an engine activation mode only under a situation in which high accuracy is not required for the control. The EV mode is a mode in which the engine is stopped and the vehicle is driven by the motor. The engine activation mode is a mode in which the engine is activated for at least one of power generation for charging a battery and driving the vehicle.

  • Publication number: 20240255963
    Abstract: A vehicle unloading management device includes a processor. When an unload request for unloading a vehicle being loaded in an airport parking lot is received from a passenger of an airplane whose arrival destination is an airport, the processor sets a time period for performing automated unload of the passenger's vehicle. In the process of setting the time period, when at least two unload requests are received from at least two vehicles and time periods for performing automated unload of the at least two vehicles overlap, the processor predicts an arrival order at the airport parking lot of a passengers corresponding to the at least two unload requests with overlapping the time periods. And the processor determines an order for automated unload of the at least two vehicles according to the arrival order.

  • Publication number: 20240257639
    Abstract: An automated parking management device includes a storage device and a processor that performs an organization processing for organizing an automated parking location of a vehicle in a parking lot. In the organization processing, the processor calculates a degree of anti-theft necessity for a loaded vehicle and a load scheduled vehicle for each vehicle. The processor calculates a degree of theft resistance for each parking spot based on a map information of the parking lot, a location information of the loaded vehicle, and a location information of the load scheduled vehicle. The processor determines an automated parking location of the loaded vehicle and the load scheduled vehicle based on the degree of anti-theft necessity and degree of theft resistance such that a vehicle with a higher degree of anti-theft necessity is parked in the parking spot with a higher degree of theft resistance.
