This application claims the benefit of Korean Patent Application No. 10-2020-0180240, filed on Dec. 21, 2020, which application is hereby incorporated herein by reference.
The present disclosure relates to a system and a method for authenticating a user of an autonomous driverless taxi (robotaxi).
The ‘MOTIONAL’, Hyundai Motor Company's US autonomous driving joint venture, is speeding up preparations for commercialization of autonomous driving.
The ‘MOTIONAL’ is recently allowed, by the state of Nevada in the United States, where Las Vegas is located, to conduct an autonomous driving test for traveling on a regular road without a driver. The ‘MOTIONAL’ is the first in Nevada to conduct the autonomous driving test in a state in which the driver is not on board. The ‘MOTIONAL’ plans to put a person in a passenger seat for safety, but plans to check an autonomous driving technology of a level 4 in an actual road situation while leaving a driver's seat empty. The level 4 is an autonomous driving stage in which the person does not intervene in driving although there is the driver's seat in case of an emergency. A Chrysler's Pacifica minivan is put in the test.
With this test, the ‘MOTIONAL’ has taken a step closer to commercialization of an autonomous taxi (a robotaxi) in 2022. The ‘MOTIONAL’ is the joint venture to which Hyundai Motor Company and Aptiv, which is a US autonomous driving company, invested $2 billion each in September 2019, and has launched a robotaxi pilot business in Singapore, Las Vegas, and the like.
A conventional technology for authenticating a user of the robotaxi is in a scheme using a smart phone on which a digital key application is installed. When the user calls the robotaxi using the smart phone and then requests unlocking of a door of the robotaxi to a server, the server authenticates the user. When the server commands a door lock/unlock controller equipped in the robotaxi to unlock the door, the door lock/unlock controller unlocks the door.
Such a conventional technology has a problem in that the user of the robotaxi is not able to be authenticated when an authentication error occurs despite a normal digital key, or when the smart phone dies after calling the robotaxi.
The matters described in this background are written to enhance an understanding of the background of the invention, and may include matters other than the prior art already known to those of ordinary skill in the field to which this technology belongs.
The present disclosure relates to a system and a method for authenticating a user of an autonomous driverless taxi (robotaxi). Particular embodiments relate to a technology for authenticating a user who has called a robotaxi.
Embodiments of the present disclosure can solve problems occurring in the prior art while advantages achieved by the prior art are maintained intact.
An embodiment of the present disclosure provides a system and a method for authenticating a user of a robotaxi that may authenticate the user of the robotaxi by authenticating the user of the robotaxi in association with a call button, a touch pad, and various sensors mounted on an exterior of the robotaxi even when an error of authentication of the user of the robotaxi using a digital key occurs or when a smart phone in which the digital key is stored dies.

As shown in
Each of the components will be described. First, a digital key application is installed on the smart phone 100. Such a digital key application may be stored in a memory (not shown). In this connection, the memory may include at least one type of recording media (storage media) of a memory of a flash memory type, a hard disk type, a micro type, a card type (e.g., a secure digital card (SD card) or an eXtream digital card (XD card)), and the like, and/or a memory of a random access memory (RAM), a static RAM (SRAM), a read-only memory (ROM), a programmable ROM (PROM), an electrically erasable PROM (EEPROM), a magnetic RAM (MRAM), a magnetic disk, and an optical disk type.
The smart phone 100 may include a mobile communication module and a wireless Internet module to communicate with the authentication server 200, and may include a short-range communication module to communicate with the robotaxi 300.
In this connection, the mobile communication module may communicate with the authentication server 200 through a mobile communication network built based on technical standards or communication schemes for mobile communication (e.g., a global system for mobile communication (GSM)), a code division multi access (CDMA), a code division multi access 2000 (CDMA2000), an enhanced voice-data optimized or enhanced voice-data only (EV-DO), a wideband CDMA (WCDMA), a high speed downlink packet access (HSDPA), a high speed uplink packet access (HSUPA), a long term evolution (LTE), a long term evolution-advanced (LTE-A), and the like), a 4th generation mobile telecommunication (4G), and a 5th generation mobile telecommunication (5G).
In addition, the wireless Internet module, which is a module for wireless Internet access, may communicate with the authentication server 200 through a wireless LAN (WLAN), a wireless-fidelity (Wi-Fi), a wireless fidelity (Wi-Fi) Direct, a digital living network alliance (DLNA), a wireless broadband (WiBro), a world interoperability for microwave access (WiMAX), a high speed downlink packet access (HSDPA), a high speed uplink packet access (HSUPA), a long term evolution (LTE), a long term evolution-advanced (LTE-A), and the like.
The short-range communication module may support short-range communication using at least one of technologies of a Bluetooth™, a radio frequency identification (RFID), an infrared data association (IrDA), an ultra wideband (UWB), a ZigBee, a near field communication (NFC), and/or a wireless universal serial bus (Wireless USB).
The smart phone 100 may transmit biometric information of a user to the authentication server 200 when signing up for a robotaxi service. In this connection, the biometric information may include a face, an iris, a fingerprint, a handwriting sample, and the like of the user.
The smart phone 100 may call the robotaxi 300 through the robotaxi service, and may request unlocking of a door to a door controller 70 of the robotaxi 300 in a state in which authentication is completed through the authentication server 200.
Hereinafter, operations of the authentication server 200 will be described by dividing a case in which an authentication error occurs despite a normal digital key and a case in which the smart phone 100 dies after calling the robotaxi 300 from each other.
First, in the case in which the authentication error (an authentication failure) occurs despite the normal digital key, that is, in a case in which the smart phone 100 fails to receive an authentication result (normal or abnormal) within a critical time (e.g., 1.5 seconds) from a time point at which an authentication request is received from the smart phone 100, the authentication server 200 may create an authentication number and provide the authentication number to the smart phone 100 as shown in
The authentication server 200 may guide the smart phone 100 about the authentication error by the digital key and transmit the authentication number to the smart phone 100. Then, the user inputs the authentication number through a touch keypad 50 equipped on the robotaxi 300 as shown in
Next, when the smart phone 100 dies after calling the robotaxi 300, as shown in
Thereafter, the user inputs biometric information through a sensor 40 equipped on the robotaxi 300, and the biometric information thus input is transmitted to the authentication server 200.
The authentication server 200 may authenticate the user by comparing the biometric information (reference biometric information) of the user stored in advance with the biometric information of the user transmitted from the robotaxi 300, and provide the authentication result to the service associate of the customer service center 400. In this connection, the authentication server 200 may create the authentication number in a case of a normal user and provide the authentication number to the service associate of the customer service center 400. Then, the service associate of the customer service center 400 provides the authentication number to the user in the case of the normal authentication.
Thereafter, the user inputs the authentication number through the touch keypad 50 equipped on the robotaxi 300. The authentication number thus input is transmitted to the authentication server 200, and the authentication server 200 authenticates the authentication number and transmits the authentication result to the door controller 70. Then, the door controller 70 unlocks the door in the case of the normal authentication, or maintains the locked state of the door in the case of the abnormal authentication.
In one example, the robotaxi 300 may include a mobile communication device 10, a short-range communication device 20, the call button 30, the sensor 40, the touch keypad 50, an audio video (AV) controller 60, and the door controller 70.
Each of the components will be described. First, the mobile communication device 10 is a module that provides a communication interface with the authentication server 200.
The short-range communication device 20 is a module that provides a communication interface with the smart phone 100.
The call button 30 may be located on an exterior (e.g., on a B pillar) of the robotaxi 300, and may be, for example, in association with a telematics terminal (not shown) to request the voice call with the service associate in the customer service center 400. Thus, the user may use the call button 30 without boarding the robotaxi 300.
The sensor 40, which is a module for acquiring a bio-signal of the user, may include at least one of a facial recognition sensor, an iris recognition sensor, a fingerprint recognition sensor, and/or a handwriting recognition sensor.
The touch keypad 50 is a module located on the exterior (e.g., on a door window) of the robotaxi 300 to receive the authentication number from the user. Accordingly, the user may use the touch keypad 50 without boarding the robotaxi 300.
The AV controller 60 may include a voice processing module and an image processing module, and may transmit the biometric information received from the sensor 40 to the door controller 70 and transmit the authentication number received from the touch keypad 50 to the door controller 70.
The door controller 70 may perform overall control such that each component may normally perform the function thereof. Such door controller 70 may be implemented in a form of hardware, may be implemented in a form of software, or may be implemented in a form in which the hardware and the software are combined with each other. Preferably, the door controller 70 may be implemented as a microprocessor, but may not be limited thereto.
The door controller 70 may be implemented as an integrated body control unit (IBU) as an example, may control the locking/unlocking of the door based on the authentication result from the authentication server 200, and may transmit the biometric information or the authentication information received from the AV controller 60 to the authentication server 200 through the mobile communication device 10.
First, the authentication server 200 receives the request for the authentication by the digital key from the smart phone 100 and performs the authentication procedure (201).
Thereafter, in the case in which the authentication error (the authentication failure) occurs despite the normal digital key, that is, in the case in which the smart phone 100 fails to receive the authentication result (normal or abnormal) within the critical time (e.g., 1.5 seconds) from the time point at which the smart phone 100 transmits the authentication request, the authentication server 200 may create the authentication number and provide the authentication number to the smart phone 100 (202). In this connection, the case in which the authentication error occurs may include a case in which a request for the unlocking of the door is not transmitted to the door controller 70, a case in which the authentication server 200 has transmitted the request for the unlocking of the door to the door controller 70, but the door controller 70 has not received the request, a case in which the authentication server 200 has received permission to unlock the door from the door controller 70, but has failed to transmit the permission to the smart phone 100, and the like.
Thereafter, the robotaxi 300 transmits the authentication number input from the user to the authentication server 200 (203).
Thereafter, the authentication server 200 authenticates the user by comparing the created authentication number with the authentication number transmitted from the robotaxi 300 (204). In this connection, the authentication server 200 may determine the user as the normal user when the created authentication number and the authentication number transmitted from the robotaxi 300 are the same.
Thereafter, the authentication server 200 requests the unlocking of the door to the door controller 70 of the robotaxi 300 when the authentication is the normal authentication (205). In this connection, the authentication server 200 does not request the unlocking of the door to the door controller 70 of the robotaxi 300 when the authentication is not the normal authentication.
Thereafter, the door controller 70 of the robotaxi 300 unlocks the door (206).
First, the authentication server 200 manages the biometric information of the user received from the user when the user signs up for the robotaxi service (301).
Thereafter, the user may press the call button 30 equipped on the robotaxi 300 to perform the voice call with the service associate of the customer service center 400. That is, the robotaxi 300 connects the user with the customer service center 400 in response to the request from the user (302).
Thereafter, the user may input the biometric information thereof through the sensor 40 equipped on the robotaxi 300. That is, the robotaxi 300 acquires the biometric information of the user through the sensor 40 (303).
Thereafter, the robotaxi 300 transmits the biometric information of the user to the authentication server 200 (304).
Thereafter, the authentication server 200 authenticates the user by comparing the biometric information of the user stored in advance with the biometric information of the user transmitted from the robotaxi 300 (305). The authentication result may be provided to the service associate of the customer service center 400 to which the voice call is connected, and the service associate of the customer service center 400 may provide the authentication number to the user in the case of the normal authentication.
Thereafter, the user may input the authentication number through the touch keypad 50 equipped on the robotaxi 300. That is, the robotaxi 300 receives the authentication number from the user (306).
Thereafter, the robotaxi 300 transmits the authentication number received from the user to the authentication server 200 (307).
Thereafter, the authentication server 200 transmits the authentication result based on the authentication number to the robotaxi 300 (308).
Thereafter, the robotaxi 300 unlocks the door when the user is the normal user, or maintains the locked state of the door when the user is not the normal user (309).
