Description

This disclosure relates to a technology for identifying target vehicles. Identifying target vehicles is crucial for vehicle management and control functions. For example, in automated valet parking (AVP) systems, identifying target vehicles is required for reliability and safety reasons. Patent Document 1 discloses a vehicle authentication method for parking lots as a technology related to the identification of target vehicles. The vehicle authentication method disclosed in Patent Document 1 transmits information instructing the target vehicle to perform a predetermined action, verifies whether the vehicle in the parking lot has performed the predetermined action, authenticates the vehicle that performed the predetermined action as the target vehicle, and performs localization. Furthermore, the following patent documents (2 to 4) demonstrate the level of technology in this field.

The system is designed to provide control and service to target vehicles within designated areas where vehicles enter and exit. One such function is Auto Valet Parking (AVP) in parking lots. AVP automatically drives target vehicles in and out of parking lots. Other examples include functions that use transport equipment to load and unload target vehicles within garages. Figure 1 is a conceptual diagram illustrating AVP (Automated Vehicle Performance). The management system 100 manages AVP in Area 2 (parking lot). The management system 100 includes sensors 150 installed in Area 2. Sensors 150 detect the position and status of each vehicle 1 within Area 2. The management system 100 manages information about each vehicle 1 based on the detection information acquired using sensors 150. The management system 100 then communicates with target vehicles within Area 2 and implements AVP for those vehicles. More specifically, the management system 100 transmits AVP-related command information to the target vehicles based on management data concerning each vehicle 1 and Area 2. AVP is implemented when the target vehicle's control system controls the vehicle according to the received command information. Similarly, functions providing control and service to other target vehicles (hereinafter referred to as "AVP and other functions") are also implemented through coordination between the management system 100 and the control systems of the vehicles 1. It is generally assumed that functions such as AVP are provided across multiple areas 2. Therefore, the management system 100 may be configured as follows. Figure 2 is a diagram showing an example of the configuration of the management system 100. The management system 100 is configured to include multiple local management devices 110a provided in multiple areas 2, and a central management device 110b that manages the multiple local management devices 110a. Each local management device 110a manages the functions in its corresponding area 2. Each local managemen
