[0001] The present invention relates to a method for smoothly supporting remote calling or autonomous parking in a parking lot.

[0002] For reference, the present application is Korean patent application filed on March 25, 2025 (Application No. 10-2025-0037656), Korean patent application filed on September 26, 2025 (Application No. 10-2025-0140358), Korean patent application filed on September 26, 2025 (Application No. 10-2025-0140367), Korean patent application filed on September 26, 2025 (Application No. 10-2025-0140370), Korean patent application filed on October 2, 2025 (Application No. 10-2025-0145433), and Korean patent application filed on October 2, 2025 (Application No Priority is claimed based on 10-2025-0145436). The entire contents of the relevant application on which this priority is based are cited as references in this application.

[0003] As automotive steering control technology advances rapidly, not only battery-equipped electric vehicles but also vehicles powered by various types of energy can possess autonomous driving capabilities.

[0004] Autonomous driving vehicles can perform autonomous driving by obtaining necessary driving information from various sensors, including radar or lidar, or by analyzing image information obtained through monitoring cameras.

[0005] Autonomous vehicles are typically equipped with GPS receivers to obtain geographical location information required for autonomous driving applications. The GPS receiver receives multiple GPS signals from satellites orbiting the Earth and provides GPS location information to the autonomous driving control unit.

[0006] Recently, in order to increase user convenience, remote calling technology that calls an autonomous vehicle parked in a parking lot to the user's location using a mobile device such as a smartphone, and autonomous parking technology that controls the autonomous vehicle to park autonomously in an empty parking space in a parking lot without the user being on board are being developed or realized.

[0007] However, if the GPS receiver installed in autonomous vehicles or mobile devices fails to properly receive GPS signals in signal dead zones such as underground parking lots, it is difficult to properly achieve functions such as remote calling or autonomous parking.

[0008] Therefore, there is a strong demand for technology that can smoothly support remote calling or autonomous parking for autonomous vehicles in areas where GPS location information is not received from satellites or where the reception sensitivity of GPS location information is weak.

[0009] The technical problem to be solved according to one embodiment of the present invention is to provide a technology that can smoothly support remote calling for an autonomous vehicle in areas where GPS location information is not received from a satellite or where the reception sensitivity of GPS location information is weak.

[0010] In addition, providing technology that can smoothly support autonomous parking for autonomous vehicles in areas where GPS location information is not received from satellites or where the reception sensitivity of GPS location information is weak may be included in the aforementioned tasks.

[0011] However, the tasks to be solved are not limited in this way.

[0012] A method for supporting a remote call performed on a mobile device according to one aspect of the present invention comprises: receiving GPS location information provided from GPS satellites in a normal mode in which GPS location information is received; receiving input information including geographical information to detect whether a first event occurs when location information different from the GPS location information is required because the GPS location information is not received or the reception sensitivity of the GPS location information is weaker than a set reference sensitivity; generating Transform GPS (TGPS) location information to be used as alternative information for the GPS location information based on the input information obtained when the occurrence of the first event is detected; and controlling to transition to a first operating mode to support a remote call of an autonomous vehicle in the normal mode when the occurrence of the first event is detected, so that the Transform GPS location information is provided to the autonomous vehicle as destination location information for the remote call.

[0013] The first event described above occurs when a wireless signal is received from at least one wireless signal generator installed in a reception blind spot where it is difficult to receive the GPS location information normally; when code information is obtained from at least one QR code installed in the reception blind spot; when a user of the mobile device in the reception blind spot directly inputs the destination location information of the remote call or selects the destination location information of the remote call from a parking lot coordinate table through the screen of the mobile device; when a user of the mobile device performs fingerprint recognition or facial recognition on a common entrance lobby phone installed in the reception blind spot, the destination location information of the remote call mapped in correspondence with the user's fingerprint recognition or facial recognition is received from a home network server communicating with the common entrance lobby phone; when, in response to a parking location confirmation request, location information mapped in correspondence with the camera installed near where the autonomous vehicle is parked and which performed license plate recognition is received from a parking location and guidance server that performs license plate recognition through cameras in the reception blind spot and controls parking location and parking guidance; and the parking location responding to vehicle information acquired by shooting while the autonomous vehicle is parked. It may occur in response to at least one of the following situations: when location information mapped in correspondence with a camera installed near where the autonomous vehicle is parked and performing license plate recognition is received from the guidance server; when vehicle information is obtained by photographing while the autonomous vehicle is parked; when a wireless signal is received from the wireless signal generator; and when location information mapped in correspondence with code information obtained by photographing the QR code installed near where the autonomous vehicle is parked is received.

[0014] When the release event of the first event occurs, the operation mode of the mobile device can be controlled to return from the first operating mode to the normal mode.

[0015] The above release event may occur in response to at least one of the following situations: when a wireless signal generated from a wireless signal generator participating in the occurrence of the first event is not received or is weak below a set sensitivity; when a Bluetooth device installed in the autonomous vehicle and the mobile device are linked through pairing; when a beacon signal is received from a BLE beacon for mode release separately installed in the autonomous vehicle; when a set time related to the first event has elapsed; when the autonomous vehicle exits the underground parking lot and a beacon signal is received from a GPS return beacon installed at the exit of the underground parking lot; when a user of the mobile device directly provides a release input for the first event through the mobile device; or when parking location information is not confirmed or exit information recognized through the camera is received from a parking location and guidance server that performs vehicle number recognition through a camera in the underground parking lot and controls parking location and parking guidance.

[0016] In the first operating mode, when the occurrence of the first event is detected, floor information of the parking lot where the mobile device is located is received from the input information obtained, and if communication with the parking location and guidance server is possible, floor information where the autonomous vehicle is parked within the same parking lot is received, and if the floor information where the mobile device is located is the same as the floor information where the autonomous vehicle is parked and is within a set distance, the user of the mobile device is notified that a remote call is possible, and if the floor information where the mobile device is located is different from the floor information where the autonomous vehicle is parked, the user is notified that they exist on a different floor, and if the floor information where the autonomous vehicle is parked is not received, the user is notified that there is a possibility of existing on either the same floor or a different floor.

In this case, the installation location information of the BLE beacon, the Wi-Fi device, or the UWB transmitter and the installation location information of the QR code may be mapped in the form of coordinates including latitude and longitude to an information storage server that communicates wirelessly with the communication module of the mobile device.

[0019] The information storage server may be a cloud server. In this case, when the information storage server receives a request for coordinates of the installation location of the BLE beacon, the Wi-Fi device, the UWB transmitter, the common entrance lobby phone, or the QR code from multiple mobile devices within a set time, it may perform waiting notifications and sequential processing to resolve congestion among autonomous vehicles to be remotely called.

[0023] The second event may occur in response to at least one of the following situations: when a wireless signal for performing autonomous parking is received from at least one wireless signal generator installed in a reception blind spot where it is difficult to receive the GPS location information normally; when code information for performing autonomous parking is obtained from at least one QR code installed in the reception blind spot; when a user of the mobile device directly inputs the destination location information for autonomous parking or selects the destination location information for autonomous parking from a parking lot coordinate table for performing autonomous parking through the screen of the mobile device in the reception blind spot; when a user of the mobile device performs fingerprint recognition or facial recognition on a common entrance lobby phone installed in the reception blind spot, an entry signal for the second event mapped in response to the user's fingerprint recognition or facial recognition is received from a home network server communicating with the common entrance lobby phone; and when a user of the mobile device directly provides the setting input for the second event through the mobile device.

[0024] When a release event of the second event occurs, the operating mode of the mobile device can be controlled to return from the second operating mode to the normal mode. At this time, the release event may occur in response to at least one of the following situations: when the autonomous vehicle reaches the destination of the autonomous parking; when the user of the mobile device directly provides a release input for the second event through the mobile device; and when parking location information related to the autonomous vehicle is received from a parking location and guidance server that performs license plate recognition through a camera in an underground parking lot and controls the parking location and parking guidance.

[0025] The travel distance of the above autonomous parking can be set within a predetermined distance.

[0026] In the second operating mode, when the occurrence of the second event is detected, it is determined whether user input of the mobile device is received; if user input is received, a parking availability status for the parking areas of the autonomous vehicle requested by the user is requested; if a parking area is available, transform GPS location information corresponding to the selected parking space of the parking area is received and generated; if user input is not received, empty parking space information within the parking area including the user's preferred parking area is received, transform GPS location information corresponding to the empty parking space selected by the user among the empty parking space information is received and generated; if the battery status of the autonomous vehicle is abnormal, transform GPS location information of a pre-stored fire safety zone is acquired and generated, and the generated transform GPS location information can be provided as parking space information corresponding to the destination location information of the autonomous parking.

[0027] The above wireless signal generator may include at least one of a BLE beacon, a Wi-Fi device, and a UWB transmitter. In this case, the destination location information includes floor information of the parking lot and may be mapped in the form of coordinates including latitude and longitude to an information storage server that communicates wirelessly with the communication module of the mobile device.

[0028] The information storage server may be a cloud server. In this case, when the information storage server receives coordinate requests for the destination location information from multiple mobile devices within a set time, it may perform waiting notifications and sequential processing to resolve congestion among autonomous vehicles to be autonomously parked.

After the short-range wireless communication is initiated, the mobile device acquires GPS-formatted location information assigned to the installation location of the short-range wireless communication device using a signal received from the short-range wireless communication device, and assigns the acquired location information to the GPS of the mobile device so that the autonomous vehicle moves underground toward the location according to the acquired location information.

[0034] The above short-range wireless communication may include at least one of BLE (Bluetooth Low Energy), Wi-Fi, or UWB (Ultra-Wideband).

[0035] Short-range wireless communication with the mobile device can be performed while the mobile device is located underground.

[0039] The above GPS-formatted location information can be received from a predetermined information storage server.

[0040] The mobile device may release the acquired location information from the location information of the mobile device upon the occurrence of a predetermined release event. At this time, the release event may include at least one of the following cases: when a signal is not received from the short-range wireless communication device or the signal strength is below a preset threshold; when the mobile device is linked with the Bluetooth device provided in the autonomous vehicle through pairing; when a mode release beacon signal is detected from a mode release beacon provided in the autonomous vehicle; when a preset time has elapsed after the acquired location information is assigned to the GPS of the mobile device; when a GPS return beacon signal is received from a GPS return beacon installed at the exit where the autonomous vehicle exits from the underground to the ground; when vehicle number information for the autonomous vehicle is received by a predetermined vehicle number recognition camera installed at the exit where the autonomous vehicle exits from the underground to the ground; when the user of the mobile device inputs the completion of autonomous exit through the mobile device; and when parking location information for the autonomous vehicle is not confirmed or exit information is received through a camera provided in the underground.

[0041] If the distance between the location based on the above-mentioned acquired location information and the autonomous vehicle is within a preset distance, the autonomous vehicle may be called.

[0042] A parking location and guidance server according to another aspect of the present invention comprises: a memory storing at least one instruction; and a processor, wherein the at least one instruction is executed by the processor, the parking location and guidance server obtains input information for obtaining GPS-formatted location information from a mobile device that has requested or intends to request autonomous exit for an autonomous vehicle located underground, determines GPS-formatted location information based on the obtained input information, and transmits the GPS-formatted location information to the mobile device so that the GPS-formatted location information is applied to the mobile device while the mobile device is located underground.

[0043] The above input information can be obtained from the mobile device located underground.

[0044] The above input information may be obtained during the process of the mobile device communicating with a short-range wireless communication device installed underground, obtained by the mobile device reading a predetermined code attached underground, or obtained by the user of the mobile device inputting into the mobile device.

[0045] The above parking location and guidance server may have floor number information in the underground area where the autonomous vehicle is parked. In this case, if the floor number information where the mobile device is located in the underground area differs from the floor number information where the autonomous vehicle is parked in the underground area, the mobile device may be controlled to display that the floor number of the mobile device's location and the parking floor of the autonomous vehicle are different.

[0046] The above GPS-type location information can be obtained from information mapped to a signal received by the mobile device from a short-range wireless communication device installed underground.

[0047] The mobile device may release the acquired location information from the location information of the mobile device upon the occurrence of a predetermined release event. At this time, the release event may include at least one of the following cases: when a signal is not received from a short-range wireless communication device installed underground as one of the input information, or when the signal strength is below a preset threshold; when the mobile device is linked with a Bluetooth device provided in the autonomous vehicle through pairing; when a mode release beacon signal is detected from a mode release beacon provided in the autonomous vehicle; when a preset time has elapsed after the acquired location information is assigned to the GPS of the mobile device; when a GPS return beacon signal is received from a GPS return beacon installed at the exit where the autonomous vehicle exits from underground to the ground; when vehicle number information for the autonomous vehicle is received by a predetermined vehicle number recognition camera installed at the exit where the autonomous vehicle exits from underground to the ground; when the user of the mobile device inputs the completion of autonomous exit through the mobile device; and when parking location information for the autonomous vehicle is not confirmed or exit information is received through the camera installed underground.

[0050] Specifically, the transformed GPS location information provided as alternative information to the aforementioned GPS location information can be provided as destination location information for the remote calling or autonomous departure of an autonomous vehicle, and accordingly, the remote calling or autonomous departure of an autonomous vehicle can be performed smoothly even in areas where the reception sensitivity of GPS location information is weak.

[0051] In addition, since it is automatically detected upon the occurrence of a first event or a second event that the autonomous vehicle is located in an area where the reception sensitivity of GPS location information is weak, inaccurate GPS location information that may occur in various situations can be replaced with transformed GPS location information representing the accurate location of the autonomous vehicle.

[0074] FIG. 1 is a block diagram illustrating a position transform system according to an embodiment of the present invention.

[0075] Referring to FIG. 1, a location transform system (1000) may include a wireless signal generator (10), a code information storage unit (20), a communication network (30), a mobile device (100), an information storage server (200), and a parking location and guidance server (500) to support remote calling or autonomous parking of an autonomous vehicle (AV, 300).

[0076] The wireless signal generator (10) may be a BLE beacon, a UWB (Ultra-wideband) transmitter, or a Wi-Fi device. The BLE beacon, UWB (Ultra-wideband) transmitter, and Wi-Fi device may output a unique ID related to location information. For example, if the beacon signal output from the BLE beacon contains a unique ID having the value #0001, the unique ID #0001 may be mapped to coordinate values ​​corresponding to the installation location or designated location of the BLE beacon within the information storage server (200). Thus, when the unique ID of the wireless signal generator (10) is obtained, the coordinate values ​​corresponding to the unique ID can be verified through the information storage server (200).

[0077] Alternatively, BLE beacons, UWB (Ultra-wideband) transmitters, and Wi-Fi devices can directly output coordinate values ​​representing latitude and longitude based on location information. That is, in this case, coordinate values ​​represented by the wireless signal generator (10) can be obtained directly without using an information storage server (200).

[0078] The code information storage unit (20) can store QR codes or barcodes. The information contained in the QR code may be unique IDs or coordinate values ​​related to location information. If the QR code contains a unique ID with the value #0002, the unique ID #0002 can be mapped to coordinate values ​​corresponding to the installation location or designated location of the code information storage unit (20) within the information storage server (200). Therefore, when the unique ID of the code information storage unit (20) is obtained, the coordinate values ​​corresponding to the unique ID can be verified through the information storage server (200).

[0079] The communication network (30) may include an LTE network and a TCP / IP network. The communication network (30) can establish data communication between a mobile device (100) and an information storage server (200). The communication network (30) can establish data communication between a mobile device (100) and an autonomous vehicle (AV) manufacturer server (400). Additionally, the communication network (30) can establish data communication between a mobile device (100) and a parking location and guidance server (500). If the communication interface of the communication network (30) is a wired interface, not only TCP / IP communication but also UART serial communication such as RS422 and RS485, and CAN communication may be included in the data communication.

[0080] The information storage server (200) can store coordinate values ​​corresponding to the unique ID of the wireless signal generator (10) or the unique ID of the code information storage unit (20). The information storage server (200) can output coordinate data corresponding to the unique ID when the unique ID of the wireless signal generator (10) or the unique ID of the code information storage unit (20) is received. The information storage server (200) can change the coordinate data corresponding to the unique ID into new coordinate data in response to a request to update the mapping information. That is, a request to update the mapping information occurs when it is necessary to change the coordinate values ​​corresponding to the unique ID. The information storage server (200) can be implemented as a cloud server.

[0081] The parking location and guidance server (500) can identify the parking location where the vehicle is parked. The parking location and guidance server (500) can perform parking guidance so that the vehicle is parked in an empty parking space. An empty parking space may refer to a parking space that is empty and not occupied by any other vehicles. In some cases, the empty parking space may be a parking space within a preferred zone preferred by the user. In other cases, the empty parking space may be a parking space within a fire safety zone provided for parking vehicles that are at risk of fire separately.

[0082] The parking location and guidance server (500) can recognize the vehicle number plate of a vehicle and perform parking location identification and parking guidance. To this end, the parking location and guidance server (500) can be connected to a camera unit (520). The camera unit (520) may include cameras having a license plate recognition (LPR) function for vehicles entering the parking lot and cameras having an image recognition function.

[0083] The parking location and guidance server (500) can recognize whether a vehicle is parked or is empty in each of the parking spaces of the underground parking lot through a detection device or a camera unit (520). The parking location and guidance server (500) can also be connected via wired or wireless connection to a parking guidance display board for performing parking guidance. The parking location and guidance server (500) communicates with the camera unit (520) to perform parking guidance for vehicles entering the underground parking lot and can recognize the parking locations where the vehicles are parked.

[0084] The parking location and guidance server (500) may include an image analyzer. The image analyzer may be implemented as a type of dedicated analysis server. The image analyzer may analyze image data provided from the parking lot camera unit (520) according to a set dedicated program. The image analyzer may perform image classification.

[0085] The parking location and guidance server (500) can guide the autonomous vehicle (300) to an empty parking space among the preferred parking areas when the user's preferred parking area is stored or designated in advance.

[0086] In one embodiment, the parking location and guidance server (500) may include an information storage server (200), or the two servers may be integrated and operated as a single server. Additionally, depending on the embodiment, when implemented such that the information storage server (200) and the parking location and guidance server (500) are each, or when either the information storage server (200) or the parking location and guidance server (500) is included within the other (e.g., the parking location and guidance server), it may be implemented in the form of a cloud server.

[0087] The autonomous vehicle (300) can perform autonomous driving under the control of a vehicle controller. To this end, the autonomous vehicle (300) may include a sensing device (301) and an autonomous vehicle (AV) driving app (310). The autonomous vehicle (300) may be an electric vehicle equipped with a battery, but the embodiments of the present disclosure are not limited thereto.

[0088] The detection device (301) of the autonomous vehicle (300) may include a sensor unit including an ultrasonic sensor, etc., and a vision-based camera. Accordingly, the detection device (301) of the autonomous vehicle (300) can detect physical elements such as lanes, walls, pillars, other vehicles, etc. as obstacles. The autonomous vehicle (300) can set a travel path while avoiding obstacles recognized through the detection device (301) and move autonomously under the control of the AV driving app (310). The AV driving app (310) may be a Full Self Driving (FSD) app.

[0089] The AV driving app (310) of the autonomous vehicle (300) can be stored in the memory of the vehicle controller and may be an application program for performing remote calling functions and autonomous parking functions.

[0090] The autonomous vehicle (300) can communicate with the AV manufacturer server (400) via the communication network (30). The autonomous vehicle (300) can communicate with the mobile device (100) via the communication network (30). The AV manufacturer server (400) can communicate with the mobile device (100) via the communication network (30). The autonomous vehicle (300) can communicate with the mobile device (100) via short-range wireless communication, for example, Bluetooth communication.

[0091] The mobile device (100) is not limited to, but may be a smartphone capable of performing mobile communication. The mobile device (100) may include a memory unit (160). An AV control app for controlling remote calling or autonomous parking of the autonomous vehicle (300) and a location transform app for supporting remote calling or autonomous parking of the autonomous vehicle (300) may be stored in the memory unit (160).

[0092] In an embodiment of the present disclosure, the mobile device (100) can support remote calling of the autonomous vehicle (300) through a location transform app as described below when the AV control app is executed. The mobile device (100) can support autonomous parking using the autonomous vehicle (300) through a location transform app as described below when the AV control app is executed.

[0093] Therefore, even in areas where GPS location information is not received from the satellite or where the reception sensitivity of GPS location information is weak, remote calling or autonomous parking can be smoothly supported for the autonomous vehicle (300).

[0094] FIG. 2 is a block diagram illustrating the mobile device (100) of FIG. 1.

[0095] Referring to FIG. 2, the mobile device (100) may include a GPS receiving module (110), a position transform object part (120), a switching part (130), a communication module (140), an AV control app object part (150), and a memory part (160).

[0096] The GPS receiving module (110) receives GPS position information in a normal mode, which is a mode in which GPS position information is received from satellites. The GPS receiving module (110) may basically include a phase-locked loop for converting satellite signals provided from GPS satellites into intermediate frequency signals and obtaining synchronization between the converted signals and an internal PRN code, and a signal processing unit for receiving and processing the output of the phase-locked loop to output a positioning result.

[0097] The location transform object part (120) is a set of modules that are operated while the location transform app is running, and may include a camera information receiving module (121), a user input receiving module (123), a BLE signal receiving module (125), a control module (127), and a transform GPS (TGPS) generation module (129).

[0098] The switching unit (130) functions as a software switch and switches one of the GPS location information and TGPS location information through the switch (SW) depending on the logic state of the switching control signal (SCS).

[0099] The communication module (140) can perform data communication through a wireless interface. The protocol used in the wireless interface may include the following protocols. The above protocols include Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), North American Digital Communications (NADC), Extended Time Division Multiple Access (E-TDMA), Wideband CDMA (WCDMA), CDMA2000, Wi-Fi, Municipal Wi-Fi (Muni Wi-Fi), Bluetooth, Digital Enhanced Cordless Telecommunications (DECT), Wireless Universal Serial Bus (Wireless USB), Fast low-latency access with seamless handoff.

[0100] The AV control app object part (150) is a module that is driven when the AV control app (162) is executed, and may include an AV control module (151).

[0101] The memory unit (160) may store an AV control app (162) and a location transform app (164). The AV control app (162) and the location transform app (164) may be linked to each other, and when the AV control app (162) is executed, the location transform app (164) may operate as a background app. Alternatively, although not limited to the present invention, the location transform app (164) may operate as a foreground app or a background app before the AV control app (162) is executed.

[0102] The memory unit (160) can store various data related to user data, remote calling, and autonomous parking volatilely or nonvolatilely. The memory unit (160) can store application programs and data required for supporting and controlling remote calling and autonomous parking of the present disclosure. The memory unit (160) may include memory such as a flash memory type, a hard disk type, a micro type, and a card type (e.g., an SD card (Secure Digital Card) or an XD card (eXtream Digital Card)), and at least one storage medium of a type of memory such as RAM (Random Access Memory), SRAM (Static RAM), ROM (Read-Only Memory), PROM (Programmable ROM), EEPROM (Electrically Erasable PROM), magnetic memory (MRAM, Magnetic RAM), magnetic disk, and optical disk.

[0103] The AV control app (162) can drive the AV control module (151) of the AV control app object part (150). The AV control app (162) may be an application program or software for controlling remote calling or autonomous parking of the autonomous vehicle (300) through a mobile device (100).

[0104] The location transform app (164) may be an application program or software for supporting remote calling or autonomous parking of an autonomous vehicle (300) via a mobile device (100). The location transform app (164) can drive the modules of the location transform object part (120).

[0105] While the location transform app (164) is running, the camera information receiving module (121) can receive camera information, such as QR code information or barcode information, received through the camera of the mobile device (100).

[0106] While the location transform app (164) is running, the user input receiving module (123) can receive information input from the user of the mobile device (100) through a touch panel, etc.

[0107] While the location transform app (164) is running, the BLE signal receiving module (125) can receive a beacon signal. Although the BLE signal receiving module (125) is illustrated as an example in the embodiment of the present disclosure, it is not limited thereto and may also include an Ultra-wideband (UWB) signal receiving module or a Wi-Fi signal receiving module.

[0108] The camera information receiving module (121), user input receiving module (123), or BLE signal receiving module (125) can be referred to as an event detection module because it is a module for detecting when location information different from GPS location information is needed, that is, when an event requiring different location information occurs.

[0109] The control module (127) may be a module for controlling and supporting remote calling or autonomous parking of the autonomous vehicle (300). The control module (127) may be implemented using, for example, a processor, a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a programmable logic unit (PLU), or a microprocessor. Alternatively, the control module (127) may be implemented using a Snapdragon 8 Elite chipset or an A18 chipset capable of executing and responding to instructions. The chipset may include an NPU, a CPU, and a GPU, so that data processing can be performed in conjunction with each other.

[0110] The control module (127) may execute an operating system (OS) and one or more software applications executed on said operating system. Additionally, the control module (127) may access, store, manipulate, process, and generate data in response to the execution of the software. For ease of understanding and illustration, the control module (127) is described as being used as one, but a person of ordinary skill in the art will know that the processing device may include multiple processing elements and / or multiple types of processing elements. For example, the control module (127) may include multiple processors or one processor and one controller. Other processing configurations, such as parallel processors, are also possible. The software may include a computer program, code, instructions, or a combination of one or more of these, and may configure the device to operate as desired or command the device independently or collectively. Software and / or data may be permanently or temporarily embodied in any type of machine, component, physical device, virtual equipment, computer storage medium or device, or transmitted signal wave, so as to be interpreted by the device or to provide commands or data to the device. Where else the matter is concerned, software may be distributed over networked computer systems and stored or executed in a distributed manner. Software and data may be stored on one or more computer-readable recording media or memory.

[0111] The control module (127) can execute the AV control app (162) and the position transform app (164) stored in the memory unit (160) in parallel.

[0112] The transform GPS (TGPS) generation module (129) can generate TGPS location information according to an embodiment of the present disclosure. The transform GPS (TGPS) generation module (129) can generate TGPS location information based on geographic information (GI) applied from the control module (127). For example, the number of data bits of the TGPS location information may be the same as the number of data bits of the GPS location information output from the GPS receiving module (110). The TGPS generation module (129) can generate TGPS location information based on input information (e.g., geographic information GI) obtained when the occurrence of a first event (e.g., a remote call event) is detected. When the TGPS generation module (129) directly receives coordinate values ​​regarding latitude and longitude as TGPS location information, it can function as a data bit formatter for outputting TGPS location information having the same number of bits as the number of data bits of the GPS location information.

[0113] Accordingly, the control module (127) may transition to or enter a first operating mode to support remote calling of an autonomous vehicle in the normal mode when the occurrence of the first event is detected. The control module (127) may control the transformation GPS location information generated from the TGPS generation module (129) in the first operating mode to be provided as destination location information for the remote call.

[0114] More specifically, the control module (127) can provide a high-level switching control signal (SCS) to the switching unit (130) in normal mode. Accordingly, the switch (SW) of the switching unit (130) causes GPS location information received from the GPS receiving module (110) to be provided to the AV control module (151). Thus, when the AV control module (151) receives GPS location information, the AV driving app (310) of the autonomous vehicle (300) can control remote calling or autonomous parking based on the GPS location information.

[0115] Meanwhile, an autonomous vehicle (300) may be parked in an area where GPS location information is not received from a satellite or where the reception sensitivity of GPS location information is weak, such as an underground parking lot. Additionally, a mobile device (100) carried by a user of the autonomous vehicle (300) may also be located in an underground parking lot. When the autonomous vehicle (300) or the mobile device (100) is located in a GPS blind spot in this way, GPS location information is not received from a satellite by the GPS receiving module (110), or the signal strength of the GPS location information received by the GPS receiving module (110) is weak. Therefore, in a GPS blind spot such as an underground parking lot, it is difficult to properly realize remote calling or autonomous parking.

[0116] Accordingly, for example, while the location transform app (164) is running, if the user is located at the common entrance of an underground parking lot, the user's mobile device (100) can receive a BLE beacon signal installed near the common entrance through a BLE receiving module (125).

[0117] The control module (127) can transmit a beacon ID included in a BLE beacon signal to an information storage server (200) via a communication module (140). The information storage server (200) can respond to the transmitted beacon ID by transmitting coordinate value information, including latitude and longitude mapped to the beacon ID, to the control module (127) via the communication module (140). Accordingly, the control module (127) can receive the coordinate value information and transmit it as Geographic Information (GI) to a Transform GPS (TGPS) generation module (129). The TGPS generation module (129) can generate TGPS location information in response to the Geographic Information (GI).

[0118] In this case, the control module (127) can provide a low-level switching control signal (SCS) to the switching unit (130). Accordingly, the switch (SW) of the switching unit (130) causes the TGPS location information generated from the TGPS generation module (129) to be provided to the AV control module (151). Thus, the AV control module (151) for controlling the driving of the autonomous vehicle (300) can receive the TGPS location information. When the AV control module (151) receives the TGPS location information, the AV driving app (310) of the autonomous vehicle (300) can control remote calling or autonomous parking based on the TGPS location information.

[0119] Meanwhile, even when the camera information receiving module (121) receives QR code information, coordinate value information mapped to the QR code information can be obtained from the information storage server (200). If the QR code information itself contains coordinate value information, TGPS location information can be directly generated from the TGPS generation module (129) without relying on the information storage server (200).

[0120] Likewise, when coordinate value information is input from the user input receiving module (123), TGPS location information can be directly generated from the TGPS generation module (129) without relying on the information storage server (200). However, when a specific ID is input from the user input receiving module (123), mapped coordinate value information can be obtained from the information storage server (200).

[0121] Similarly, if coordinate value information can be included in the BLE beacon signal, TGPS location information can be directly generated from the TGPS generation module (129) without relying on the information storage server (200).

[0122] In one embodiment, the operation of generating TGPS location information of the aforementioned TGPS generation module (129) may also be performed at the parking location and guidance server (500), and when TGPS location information is generated at the parking location and guidance server (500), the generated TGPS location information may be transmitted from the parking location and guidance server (500) to the mobile device (100).

[0123] As described above, by executing the location transform app (164), remote calling or autonomous parking can be smoothly supported for the autonomous vehicle (300) even in areas where GPS location information is not received from the satellite or where the reception sensitivity of GPS location information is weak.

[0124] FIG. 3 is a flowchart illustrating a remote call support operation in a mobile device according to an embodiment of the present invention.

[0125] Referring to FIG. 3 together with FIG. 1 and 2, in operation S310, the control module (127) of the mobile device (100) can perform a normal mode operation. In this case, the control module (127) can output a high-level switching control signal (SCS) to the switching unit (130). Accordingly, GPS location information received from the GPS receiving module (110) can be provided to the AV control module (151). In the case of normal mode operation, the location transform app (164) can be executed as a background app of the mobile device (100).

[0126] Even when an autonomous vehicle (300) is parked in an underground parking lot that may be a GPS blind spot, the user can use a mobile device (100) to initiate a remote call (or Smart Summon). When a remote call is initiated, the execution of the AV control app (162) begins.

[0127] In operation S311, the control module (127) of the mobile device (100) can determine whether a first event occurs. The first event may occur when the mobile device (100), carried by the user of the autonomous vehicle (300) for remote calling, receives a wireless signal in a specific area of ​​an underground parking lot.

[0128] For example, when a wireless signal is received from at least one wireless signal generator (e.g., BLE signal receiving module (125)) installed in a reception blind spot, the control module (127) may determine that a first event occurs. In this case, the distance between the autonomous vehicle (300) and the remote call destination may be within 70 meters (70 meters).

[0129] Additionally, when obtaining code information from at least one QR code installed in a reception blind spot, the control module (127) may determine that a first event occurs. In this case, when a user photographs a QR code, the camera information receiving module (121) may receive the photographed QR code. In this case, the distance between the autonomous vehicle (300) and the remote call destination may be within 70 meters (70 meters).

[0130] Additionally, when a user of a mobile device (100) directly inputs the destination location information of the remote call in a reception dead zone, or when the user selects the destination location information of the remote call from a coordinate table of an underground parking lot through the screen of the mobile device (100), the control module (127) may determine that a first event occurs. In this case, the distance between the autonomous vehicle (300) and the remote call destination may be within 70 meters (70 meters).

[0131] Additionally, when a user of the mobile device (100) performs fingerprint recognition or facial recognition on a common entrance lobby phone installed in a reception dead zone, and the destination location information of the remote call mapped in correspondence with the user's fingerprint recognition or facial recognition is received from a home network server communicating with the common entrance lobby phone, the control module (127) may determine that a first event occurs. In this case, the distance between the autonomous vehicle (300) and the remote call destination may be within 70 meters (70 meters).

[0132] Additionally, when the destination location information of the remote call is received from a parking location and guidance server that performs license plate recognition through cameras in a reception blind spot in response to a parking location confirmation request and controls the parking location and parking guidance, the destination location information of the remote call is mapped to correspond to the camera installed near (or closest to) where the autonomous vehicle (300) is parked and which performed license plate recognition, the control module (127) may determine that a first event occurs. In this case, the distance between the autonomous vehicle (300) and the remote call destination may be within 6 meters (6 meters). Additionally, the distance between the autonomous vehicle (300) and the mobile device (100) may exceed 6 meters (6 meters).

[0133] Additionally, when the destination location information of the remote call, which is mapped in correspondence with a camera installed near where the autonomous vehicle (300) is parked and performs license plate recognition, is received from a parking location and guidance server that responds to vehicle information obtained by shooting while the autonomous vehicle (300) is parked, the control module (127) may determine that a first event occurs. In this case, the distance between the autonomous vehicle (300) and the remote call destination may be within 6 meters (6 meters). Additionally, the distance between the autonomous vehicle (300) and the mobile device (100) may also be within 6 meters (6 meters).

[0134] Additionally, when vehicle information is obtained by photographing while the autonomous vehicle (300) is parked, and a wireless signal is received from a wireless signal generator (10), the control module (127) may determine that a first event occurs. In this case, the distance between the autonomous vehicle (300) and the remote call destination may be within 6 meters (6 meters). Additionally, the distance between the autonomous vehicle (300) and the mobile device (100) may also be within 6 meters (6 meters).

[0135] Additionally, when the destination location information of the remote call mapped in correspondence with code information obtained by photographing a QR code installed near the location where the autonomous vehicle (300) is parked is received, the control module (127) may determine that a first event occurs. In this case, the distance between the autonomous vehicle (300) and the remote call destination may be within 6 meters (6 meters). Additionally, the distance between the autonomous vehicle (300) and the mobile device (100) may also be within 6 meters (6 meters).

[0136] When the first event occurs in operation S311, the control module (127) of the mobile device (100) can transition the operation mode to the first operating mode in operation S312. That is, the control module (127) of the mobile device (100) can change the operation mode from normal mode operation to the first operating mode. In this case, the control module (127) of the mobile device (100) can output a low-level switching control signal (SCS). Accordingly, the switch (SW) of the switching unit (130) is connected to the switching node (S2) so that when TGPS location information is generated from the TGPS generation module (129), TGPS location information can be provided to the AV control module (151).

[0137] Meanwhile, the change from normal mode operation to the first operating mode can be performed based on the order of waiting for remote call connections. When multiple users make remote calls from the same remote call destination, multiple autonomous vehicles may move to the same remote call destination at once. In such cases, congestion or blockage caused by vehicles in the underground parking lot may occur. To prevent this, the information storage server (200) can provide sequence information related to remote calls to multiple mobile devices as described below.

[0138] In operation S313, the control module (127) of the mobile device (100) can obtain TGPS location information. Additionally, the control module (127) of the mobile device (100) can control the TGPS generation module (129) to generate TGPS location information.

[0139] Acquisition of TGPS location information can be achieved when TGPS location information is directly provided to the user input receiving module (123). For example, TGPS location information can be acquired when coordinate values ​​including latitude and longitude are directly provided. Meanwhile, generation of TGPS location information can be achieved when the TGPS generation module (129) obtains coordinate values ​​including latitude and longitude based on Geographic Information (GI) authorized from the control module (127). For example, when coordinate values ​​mapped to correspond to the unique ID of the wireless signal generator (10) are provided from the information storage server (200), the TGPS generation module (129) can generate TGPS location information having the same number of bits as the number of data bits of GPS information as destination information for a remote call. In this case, the destination information for a remote call refers to the geographical point where the autonomous vehicle (300) will arrive in response to the remote call, and may represent the location where the mobile device (100) is located or nearby geographical location information.

[0140] In operation S314, the control module (127) of the mobile device (100) can provide TGPS location information provided from the TGPS generation module (129) to the switching unit (130). The switching unit (130) can allow the TGPS location information to be applied to the AV control module (151). Accordingly, the AV control module (151) can receive the TGPS location information as destination information for a remote call. When the AV control module (151) receives the TGPS location information, the AV driving app (310) of the autonomous vehicle (300) can control the remote call based on the TGPS location information. By means of the remote call, the autonomous vehicle (300) can be called to the coordinate point of the underground parking lot indicated by the TGPS location information, which is the destination information for the remote call.

[0141] Ultimately, by executing the location transform app (164), TGPS location information can be provided, so remote calling to the autonomous vehicle (300) can be smoothly supported even in an underground parking lot.

[0142] In operation S315, the control module (127) of the mobile device (100) can determine whether the release event of the first event occurs.

[0143] The release event of the first event may occur when the wireless signal generated from the wireless signal generator (10) that participated in the occurrence of the first event is not received or is weak below a set sensitivity. Additionally, the release event of the first event may occur when the Bluetooth device installed in the autonomous vehicle (300) and the mobile device (100) are linked through pairing. Additionally, the release event of the first event may occur when a beacon signal is received from a BLE beacon for mode release separately installed in the autonomous vehicle (300). Additionally, the release event of the first event may occur when a set time (e.g., 7 minutes) related to the first event has elapsed. Additionally, the release event of the first event may occur when the autonomous vehicle (300) exits the underground parking lot and a beacon signal is received from a GPS return beacon installed at the exit of the underground parking lot. Additionally, the release event of the first event may occur when a user of the mobile device (100) directly provides the release input of the first event through the mobile device (100). Additionally, the release event of the first event may occur when parking location information is not confirmed or exit information is received from a parking location and guidance server (500) that performs vehicle number recognition through a camera in an underground parking lot and controls parking location and parking guidance.

[0144] When a release event of the first event occurs, in operation S316, the control module (127) of the mobile device (100) can control the mobile device's operation mode to return from the first operation mode to the normal mode. In this case, the control module (127) of the mobile device (100) can apply a high-level switching control signal (SCS) to the switching unit (130). Accordingly, the switch (SW) of the switching unit (130) returns and is connected to the switching node (S1). Therefore, GPS location information received through the GPS receiving module (110) can be provided to the AV control module (151). Thus, the AV driving app (310) of the autonomous vehicle (300) can operate based on the GPS location information.

[0145] FIG. 4A is a block diagram illustrating the detailed control operation of the first operating mode of FIG. 3.

[0146] In operation S410, the control module (127) of the mobile device (100) can obtain floor information of the parking lot. The signal transmitted from the wireless signal generator (10) may include a unique ID, and the unique ID may include floor information of the parking lot where the wireless signal generator (10) is located. Accordingly, the control module (127) of the mobile device (100) can obtain floor information of the parking lot from the wireless signal generator (10) or the code information storage unit (20). Ultimately, the floor information of the parking lot may represent information of the floor where the mobile device (100) is located. Alternatively, the control module (127) of the mobile device (100) can obtain floor information of the parking lot from an information storage server (200) that stores various information mapped to the unique ID of the wireless signal generator (10) or the code information storage unit (20).

[0147] In operation S411, the control module (127) of the mobile device (100) can determine whether a communication connection is possible with the parking location and guidance server (500). If the parking location and guidance server (500) of FIG. 1 is not installed or communication is interrupted through the communication network (30), the control module (127) of the mobile device (100) can determine that a communication connection between the mobile device (100) and the parking location and guidance server (500) is not possible. If a communication connection is possible between the mobile device (100) and the parking location and guidance server (500), the parking location and guidance server (500) can check the floor and parking location information where the autonomous vehicle (300) is parked within the underground parking lot, and thus can provide floor information of the autonomous vehicle (300).

[0148] In operation S411, if the control module (127) of the mobile device (100) is able to communicate with the parking location and guidance server, in operation S412, the control module (127) of the mobile device (100) can determine whether the parking lot floor information where the autonomous vehicle (300) is parked is received.

[0149] In operation S413, the control module (127) of the mobile device (100) can determine whether the mobile device (100) and the autonomous vehicle (300) are located on the same floor by comparing the floor information of the mobile device (100) with the floor information of the parking lot where the autonomous vehicle (300) is parked.

[0150] If it is determined in operation S413 that the mobile device (100) and the autonomous vehicle (300) are located on the same floor, in operation S414 the control module (127) of the mobile device (100) can notify through the display screen of the mobile device (100) that remote calling is possible on the same floor of the underground parking lot.

[0151] In operation S415, the control module (127) of the mobile device (100) can control that TGPS location information is provided for remote calling according to the selection of the user of the mobile device (100).

[0152] If communication connection with the parking location and guidance server is not possible in operation S411 and parking lot floor information is not received in operation S412, in operation S416, the control module (127) of the mobile device (100) can notify through the display screen of the mobile device (100) whether the mobile device (100) and the autonomous vehicle (300) are on the same floor or not on the same floor.

[0153] If it is determined in operation S413 that the mobile device (100) and the autonomous vehicle (300) are located on different floors, in operation S417 the control module (127) of the mobile device (100) can notify through the display screen of the mobile device (100) that the mobile device (100) and the autonomous vehicle (300) are on different floors.

[0154] In FIG. 4A, the detailed control operation of the first operating mode explains that remote calling is possible smoothly when the mobile device (100) and the autonomous vehicle (300) are on the same floor, but it should be understood that even if the mobile device (100) and the autonomous vehicle (300) are on different floors, TGPS location information for remote calling can be provided according to user selection.

[0155] FIG. 4B is a block diagram illustrating other detailed control operations of the first operating mode of FIG. 3.

[0156] Referring to FIG. 4B, in operation S420, the control module (127) of the mobile device (100) may request the parking location and guidance server (500) to confirm the parking location where the autonomous vehicle (300) is parked. In this case, the mobile device (100) does not need to be located in an underground parking lot.

[0157] In operation S422, the control module (127) of the mobile device (100) can receive location information mapped to a camera installed near the parked autonomous vehicle (300) and performing license plate recognition from the parking location and guidance server (500). When the parking location and guidance server (500) receives a request from the mobile device (100) to confirm the parking location of the autonomous vehicle (300), the parking location and guidance server (500) can search for a nearby camera that performs license plate recognition corresponding to the location where the autonomous vehicle (300) is parked within the camera device unit (520). The parking location and guidance server (500) can provide location information mapped to a camera installed near the location where the autonomous vehicle (300) is parked and performing license plate recognition.

[0158] In operation S423, the control module (127) of the mobile device (100) can generate TGPS location information based on the received location information.

[0159] In operation S424, the control module (127) of the mobile device (100) can provide the generated TGPS location information as destination coordinate information for a remote call.

[0160] In the case of FIG. 4B, the distance between the autonomous vehicle (300) and the remote call destination (e.g., TGPS location information mapped to a camera installed near where the autonomous vehicle (300) is parked and which performs license plate recognition) may be, for example, within 6 meters (6 meters). Additionally, the distance between the autonomous vehicle (300) and the mobile device (100) may exceed 6 meters, not limited to 6 meters (6 meters).

[0161] Meanwhile, when making a remote call, operation S421 may be provided to limit the distance between the autonomous vehicle (300) and the mobile device (100) to within 6 meters (6 meters).

[0162] Operation S421 is provided to limit the distance between the autonomous vehicle (300) and the mobile device (100) to within 6 meters (6 meters). In Operation S421, the user can use the mobile device (100) to photograph the license plate number of the autonomous vehicle (300). The photographed license plate number of the autonomous vehicle (300) can be transmitted to the parking location and guidance server (500).

[0163] After operation S421 is performed, the control module (127) of the mobile device (100) can proceed to the aforementioned operation S422.

[0164] FIG. 4C is a block diagram illustrating another detailed control operation of the first operating mode of FIG. 3.

[0165] Referring to FIG. 4C, in operation S440, the control module (127) of the mobile device (100) can obtain vehicle information (e.g., license plate number) of the autonomous vehicle (300) that has been captured. To do this, the user can use the mobile device (100) to capture the license plate number of the autonomous vehicle (300) within an underground parking lot. The captured license plate number can be provided to the parking location and guidance server (500).

[0166] With vehicle information of the autonomous vehicle (300) obtained by the above-mentioned shooting operation, in operation S441, the control module (127) of the mobile device (100) can determine whether a wireless signal is received. When a beacon signal is received from a wireless signal generator (10) which is installed near where the autonomous vehicle (300) is parked and may be a BLE beacon, in operation S442, the control module (127) of the mobile device (100) can obtain a unique ID related to the location from the received wireless signal.

[0167] In operation S443, the control module (127) of the mobile device (100) can generate TGPS location information based on location information mapped to a unique ID. The control module (127) of the mobile device (100) can provide the generated TGPS location information as destination coordinate information for a remote call.

[0168]

[0169] In the case of FIG. 4C, the distance between the autonomous vehicle (300) and the remote call destination can be set to, for example, within 6 meters (6 meters). Additionally, the distance between the autonomous vehicle (300) and the mobile device (100) can also be set to within 6 meters (6 meters).

[0170] FIG. 4D is a block diagram illustrating another detailed control operation of the first operating mode of FIG. 3.

[0171] Referring to FIG. 4D, in operation S430, the control module (127) of the mobile device (100) can transmit QR code information captured near the location where the autonomous vehicle (300) is parked to the information storage server (200). To do this, the user can capture a QR code located near the location where the autonomous vehicle (300) is parked. Additionally, the information storage server (200) can search for location information corresponding to the received QR code in a mapping table and provide location information.

[0172] In operation S431, the control module (127) of the mobile device (100) can receive location information correspondingly mapped to the QR code.

[0173] In operation S432, the control module (127) of the mobile device (100) can generate TGPS location information based on the received location information.

[0174] In operation S433, the control module (127) of the mobile device (100) can provide the generated TGPS location information as destination coordinate information for a remote call.

[0175] In this case, the distance between the autonomous vehicle (300) and the remote call destination may be, for example, within 6 meters (6 meters). Also, the distance between the autonomous vehicle (300) and the mobile device (100) may also be within 6 meters (6 meters).

[0176] FIG. 5 is a diagram schematically illustrating the execution of a remote call according to an embodiment of the present invention. FIG. 5 is a diagram that allows the detailed control operation of the first operating mode described through FIG. 4A to be more easily understood.

[0177] Referring to FIG. 5, a user and a mobile device (100) may be located at a wireless signal generator (10) installed, for example, near the common entrance of the first basement floor (B1). In this case, if the location transform app (164) is running in the background, the mobile device (100) receives mapping information corresponding to the unique ID of the wireless signal generator (10) and enters a first operating mode that provides TGPS location information. When the user runs the AV control app (162) for remote calling through the mobile device (100), the user's current location, i.e., the generated TGPS location information, becomes the destination information for the remote call. Accordingly, an autonomous vehicle (300) parked in the parking area of ​​the first basement floor (B1) moves autonomously under the support of an information storage server (200), an AV manufacturer server (400), and a parking location and guidance server (500) connected to a communication network (30), and arrives at the location where the user is present.

[0178] Meanwhile, it should be understood that TGPS location information for remote calling may be provided according to user selection even when the mobile device (100) and the autonomous vehicle (300) are located on different floors. For example, if the autonomous vehicle (300) parked on the third basement floor (B3) is an autonomous vehicle capable of recognizing destination floor information and moving to the generated TGPS location information on the first basement floor by relying on stored steering angle information and camera information, the user can execute a remote call.

[0179] FIG. 6 is a flowchart illustrating an autonomous parking assistance operation in a mobile device according to an embodiment of the present invention.

[0180] Referring to FIG. 6, autonomous parking refers to a process where a user exits an autonomous vehicle (300), and the autonomous vehicle (300) moves on its own to a parking destination, such as an empty parking space in an underground parking lot or an empty parking space within a designated parking area, and then parks. Ultimately, autonomous parking is conceptually similar to valet parking, but differs from valet parking in that the vehicle parks itself without a driver.

[0181] Referring to FIG. 6 together with FIG. 1 and 2, in operation S610, the control module (127) of the mobile device (100) can perform a normal mode operation. Since operation S610 is identical to the aforementioned operation S310, further explanation is omitted to avoid redundancy.

[0182] Similar to remote calling, in the case of autonomous parking, the location transform app (164) can be run as a background app of the mobile device (100). When the autonomous vehicle (300) is stopped in an underground parking lot that may be a GPS dead zone, the user can use the mobile device (100) to trigger autonomous parking (or reverse summon). When autonomous parking occurs, the execution of the AV control app (162) of the mobile device (100) begins.

[0183] In operation S611, the control module (127) of the mobile device (100) can determine whether a second event occurs. The second event may occur when the mobile device (100), carried by the user of the autonomous vehicle (300) for autonomous parking, receives a wireless signal in a specific area of ​​the underground parking lot.

[0184] For example, when the GPS receiving module (110) is located in a reception blind spot where it is difficult to receive GPS location information normally, a second event may occur when a wireless signal for performing autonomous parking is received from at least one wireless signal generator (10) installed in the reception blind spot.

[0185] Additionally, a second event may occur when obtaining QR code information for performing autonomous parking from at least one code information storage unit (20) installed in a reception blind spot.

[0186] Additionally, a second event may occur when a user of a mobile device (100) directly inputs the destination location information of the autonomous parking in a reception dead zone, or selects the destination location information of the autonomous parking from a parking lot coordinate table for performing the autonomous parking through the display screen of the mobile device (100).

[0187] Additionally, when a user of a mobile device (100) performs fingerprint recognition or facial recognition at a common entrance lobby phone installed in a reception dead zone, a second event may occur when an entry signal for the second event, mapped in response to the user's fingerprint recognition or facial recognition, is received from a home network server communicating with the common entrance lobby phone.

[0188] Additionally, a second event may occur when a user of a mobile device (100) directly provides the setting input for the second event through the mobile device (100).

[0189] If a second event occurs in operation S611, the control module (127) of the mobile device (100) can transition the operation mode to a second operation mode in operation S612. That is, the control module (127) of the mobile device (100) can change the operation mode from normal mode operation to a second operation mode. In this case, the control module (127) of the mobile device (100) can output a low-level switching control signal (SCS). Accordingly, the switch (SW) of the switching unit (130) is connected to the switching node (S2) so that when TGPS location information is generated from the TGPS generation module (129), TGPS location information can be provided to the AV control module (151).

[0190] Meanwhile, the change from normal mode operation to the second operating mode can also be performed based on the order of waiting for autonomous parking access in order to prevent or reduce congestion or blockage in the underground parking lot.

[0191] In operation S613, the control module (127) of the mobile device (100) can control the creation of TGPS location information corresponding to an empty parking space as a parking destination for the autonomous vehicle (300) by referring to the parking status information.

[0192] TGPS location information to be generated for autonomous parking can be generated when TGPS location information is directly provided to the user input receiving module (123). Additionally, TGPS location information to be generated for autonomous parking can be generated by user selection or designation based on empty parking space information.

[0193] The destination information for autonomous parking refers to the geographical location where the autonomous vehicle (300) will park in response to the autonomous parking command, and can represent the geographical location information of an empty parking space.

[0194] In operation S614, the control module (127) of the mobile device (100) can provide TGPS location information provided from the TGPS generation module (129) to the switching unit (130). The switching unit (130) can allow the TGPS location information to be applied to the AV control module (151). Accordingly, the AV control module (151) can receive the TGPS location information as destination information for autonomous parking. When the AV control module (151) receives the TGPS location information, the AV driving app (310) of the autonomous vehicle (300) can control autonomous parking based on the TGPS location information. Through autonomous parking, the autonomous vehicle (300) can move to the coordinate point of the underground parking lot indicated by the TGPS location information, which is the destination information for autonomous parking.

[0195] Ultimately, by executing the location transform app (164), TGPS location information for autonomous parking can be provided through the transform GPS (TGPS) generation module (129), so autonomous parking can be smoothly supported for the autonomous vehicle (300) even in an underground parking lot.

[0196] In operation S615, the control module (127) of the mobile device (100) can determine whether the release event of the second event occurs.

[0197] The release event of the second event may occur when the autonomous vehicle (300) reaches the destination of autonomous parking.

[0198] Additionally, when a user of a mobile device (100) directly provides a release input for the second event through the mobile device (100), a release event for the second event may occur.

[0199] Additionally, when parking location information related to the autonomous vehicle (300) is received from a parking location and guidance server (500) that performs vehicle number recognition through a camera in an underground parking lot and controls the parking location and parking guidance, a release event of the second event may occur.

[0200] In the event that a release event of the second event occurs in operation S615, in operation S616, the control module (127) of the mobile device (100) can control the operation mode of the mobile device (100) to return from the second operation mode to the normal mode.

[0201] In this case, the control module (127) of the mobile device (100) can apply a high-level switching control signal (SCS) to the switching unit (130). Accordingly, the switch (SW) of the switching unit (130) is restored and connected to the switching node (S1), so that GPS location information received through the GPS receiving module (110) can be provided to the AV control module (151). Thus, the AV driving app (310) of the autonomous vehicle (300) can operate based on the GPS location information.

[0202] FIG. 7 is a block diagram illustrating the detailed control operation of the second operating mode of FIG. 6.

[0203] Referring to FIG. 7, the control module (127) of the mobile device (100) can start operation in a second operating mode.

[0204] In operation S710, the control module (127) of the mobile device (100) can check whether user input is received. When user input is received by the user input receiving module (123) of FIG. 2, the control module (127) of the mobile device (100) can determine that user input is received.

[0205] When user input is received in operation S710, in operation S711, the control module (127) of the mobile device (100) may request the parking location and guidance server (500) to request the parking availability status for the parking areas of the autonomous vehicle (300) requested by the user. Accordingly, the parking location and guidance server (500) may provide the parking availability area in response to the request for the parking availability status.

[0206] If a parking area exists in operation S712, in operation S713, the control module (127) of the mobile device (100) can generate transform GPS location information corresponding to a selected parking space within the parking area through the transform GPS (TGPS) generation module (129). The information storage server (200) can store the TGPS location information mapped to correspond to the parking spaces within the parking area. Consequently, TGPS location information corresponding to each empty parking space can be mapped.

[0207] In operation S714, the control module (127) of the mobile device (100) provides the generated TGPS location information as parking space information of the parking destination.

[0208] If user input is not received in operation S710, in operation S716, the control module (127) of the mobile device (100) can receive information on empty parking spaces within the parking area from the parking location and guidance server (500).

[0209] In operation S717, the control module (127) of the mobile device (100) can generate transform GPS (TGPS) location information corresponding to the selected empty parking space.

[0210] Meanwhile, in the event that the battery status of the autonomous vehicle (300) is abnormal, the control module (127) of the mobile device (100) in operation S718 may generate transform GPS location information of a pre-stored fire safety zone to prevent fire. If the battery of the autonomous vehicle (300) overheats or there is a risk of explosion, the control module (127) of the mobile device (100) may receive a battery status message from the manufacturer server (400). Additionally, if the abnormal battery status of the autonomous vehicle (300) is received from the autonomous vehicle (300) to the mobile device (100), the control module (127) of the mobile device (100) may receive a battery status message.

[0211] When the execution of operations S717 and S718 is completed, the above-described operation S714 may be performed.

[0212] FIG. 8 is a block diagram illustrating a position transform system according to another embodiment of the present invention.

[0213] FIG. 8 shows a configuration identical or similar to that of FIG. 1, except for the home net server (600), a plurality of wall pads (620-1, 620-2, ..., 620-n), and a common entrance lobby phone (650). The common entrance lobby phone (650) can provide the same or similar functions as the wireless signal generator (10) or code information storage unit (20) of FIG. 1.

[0214] Multiple wall pads (620-1, 620-2, ..., 620-n) can be installed correspondingly in each household of the multi-unit housing. For example, if the first wall pad (620-1) is installed in the living room of Unit 101 in Building 101, the second wall pad (620-2) can be installed in the living room of Unit 102 in Building 101. The multiple wall pads (620-1, 620-2, ..., 620-n) can make calls and communicate with the common entrance lobby phone (650) through the home net server (600).

[0215] In FIG. 8, a plurality of cameras (520-1, 520-2, ..., 520-n) may correspond to the camera device part (520) of FIG. 1.

[0216] Multiple cameras (520-1, 520-2, …, 520-n) are installed one by one in correspondence with multiple parking spaces in an underground parking lot to acquire images of vehicles and parking spaces. Additionally, the multiple cameras (520-1, 520-2, …, 520-n) can provide a license plate recognition function to recognize license plate numbers of vehicles. A unique ID related to the installation location may be assigned to the multiple cameras (520-1, 520-2, …, 520-n).

[0217] More specifically, a plurality of cameras (520-1, 520-2, ..., 520-n) internally include an image sensor and a system-on-chip and can be installed in a location capable of capturing images of parking spaces (e.g., 6 parking spaces or 12 parking spaces) within a parking lot. The image sensor can receive and capture images of the parking spaces partitioned in the parking lot through an omnidirectional camera lens. The omnidirectional camera lens can be implemented as a fisheye lens. The fisheye lens may be a lens capable of capturing images of at least 4 or 6 or more parking spaces. In another embodiment, the fisheye lens may be a lens capable of capturing images of 12 parking spaces. The system-on-chip can capture and process the images of the parking spaces captured through the image sensor to generate a full space indicator control signal indicating the parking status on the parking spaces. The above-mentioned full space indicator control signal can be generated by converting the original parked image into grayscale and then using a binarized image obtained by binarizing the grayscale image. That is, the image within the target area in the binarized image can be used to determine whether the parking space is empty. By detecting edges within the target area in the current frame and the previous frame, respectively, and comparing them with each other, the parking status in the corresponding parking space can be determined. Accordingly, a full space indicator showing whether the parking space is empty or occupied can be implemented.

[0218] In addition, multiple cameras (520-1, 520-2, ..., 520-n) may be installed correspondingly at each intersection or direction change path where straight, left / right turns occur within the parking lot. Recognition of vehicle license plates may be used to determine the location information of the vehicle for parking guidance control.

[0219] The home network server (600) of FIG. 8 can communicate with a mobile device (100) through a communication network (30). The home network server (600) can store TGPS location information that is mapped correspondingly to a common entrance lobby phone (650) for remote calling. The TGPS location information mapped in the remote call becomes the destination location information for the remote call and can indicate a geographical location near the common entrance lobby phone (650). When a user performs fingerprint recognition or facial recognition through the common entrance lobby phone (650), the home network server (600) can provide unique information corresponding to the user, such as a phone number, vehicle type information, vehicle number, and information on the building and unit number of the apartment complex.

[0220] Additionally, in the case of autonomous parking, the user of the mobile device (100) can perform key or touch input, fingerprint recognition, or facial recognition through the common entrance lobby phone (650). In this case, the home net server (600) can provide an entry signal for the second event mapped to the user who performed the key or touch input, fingerprint recognition, or facial recognition, or provide destination location information for the autonomous parking.

[0221] Although the homenet server (600) has been described as providing destination information during a remote call or autonomous parking operation, it should also be understood that the present disclosure is not limited thereto and may provide mapped destination information during a remote call or autonomous parking operation through the information storage server (200).

[0222] FIG. 9 is a diagram illustrating the application range of a remote call support operation according to an embodiment of the present invention.

[0223] Referring to FIG. 9, the distances from the gate of the common entrance within the parking area of ​​the parking lot to the parked vehicle are shown as 50m, 70m, and 100m, respectively. In the case of remote calling, the callable distance may be limited to within 70m. However, it should be understood that the embodiments of the present disclosure are not limited thereto, and in special cases, the distance may be limited to within 50m or 7m through settings in the application (or app).

[0224] FIG. 10 is a block diagram illustrating a position transform system having sequential waiting operations according to another embodiment of the present invention.

[0225] Referring to FIG. 10, the position transform system (3000) may further include a plurality of mobile devices (100-1, 100-2, 100-3, …, 100-n) and a plurality of autonomous vehicles (300-1, 300-2, 300-3, …, 300-n) compared to the position transform system (1000) of FIG. 1.

[0226] For example, when multiple mobile devices (100-1, 100-2, 100-3, ..., 100-n) receive wireless signals from a wireless signal generator (10) and perform remote calling or autonomous parking based on TGPS location information substantially simultaneously, multiple autonomous vehicles (300-1, 300-2, 300-3, ..., 300-n) move at once, so blockage or confusion may occur in the underground parking lot.

[0227] Meanwhile, if the wireless signal generator (10) is a beacon, multiple BLE beacons may be installed in the underground parking lot. In this case, the mobile device (100-1) can receive multiple BLE signals from multiple BLE beacons. The mobile device (100-1) can determine the BLE signal with the strongest signal strength among the received BLE signals as the valid signal for obtaining a unique ID.

[0228] When a remote call is made, if a request for coordinates of the installation location of a BLE beacon, UWB transmitter, common entrance lobby phone, or QR code is received from multiple mobile devices (100-1, 100-2, 100-3,…,100-n) within a set time, waiting notification and sequential processing are required to relieve congestion of the autonomous vehicles (300-1, 300-2, 300-3,…,300-n) to be remotely called.

[0229] In addition, when coordinate requests for destination location information are received from multiple mobile devices (100-1, 100-2, 100-3, …, 100-n) within a set time during autonomous parking, waiting notification and sequential processing are also required to resolve congestion among autonomous vehicles (300-1, 300-2, 300-3, …, 300-n) to be autonomously parked.

[0230] Accordingly, the information storage server (200) can perform sequential waiting control operations as described later through FIG. 11.

[0231] FIG. 11 is a flowchart illustrating sequential waiting control operations in the information storage server (200) of FIG. 10.

[0232] Referring to FIG. 11, in operation S1110, the information storage server (200) determines whether a request is received from the mobile device (100-1).

[0233] When a request is received, in operation S1111, the information storage server (200) can read the TGPS location information mapped to the requested unique ID from the stored mapping table and provide it to the mobile device (100-1).

[0234] In operation S1112, the information storage server (200) determines whether a request is received from another mobile device (100-2).

[0235] When a request is received from another mobile device (100-2), in operation S1113, the information storage server (200) determines whether the requested unique ID is the same as the previously requested unique ID. That is, it is determined whether the destination location of the previously requested remote call and the destination location of the currently requested remote call are the same.

[0236] When requests related to the same location are received, in operation S1114, the information storage server (200) can determine whether the request is within a set time. For example, if the set time is set to 5 minutes, it can be determined whether a request from another mobile device (100-2) was received after 5 minutes have elapsed since the request from the mobile device (100-1) was received. Additionally, although not limiting the present invention, count information counting how many vehicles were exited from the parking lot or how many vehicles were exited from the parking spaces in the parking area when a remote call was made by referring to the exit information of the autonomous vehicles (300-1, 300-2, 300-3, ..., 300-n) or the exit information from the parking area within the parking lot can be additionally reflected in the standby control operation.

[0237] In operation S1115, if the current request is a request received within a set time, the information storage server (200) may provide a waiting signal to another mobile device (100-2). Accordingly, the user of the other mobile device (100-2) may recognize that the user of the mobile device (100-1) has performed the remote call first and wait.
