Abstract

Claims (70)

1 . A system for authenticating a user of a robotaxi, the system comprising:

an authentication server configured to:

receive an authentication request from the user;

perform an authentication procedure in response to the authentication request;

determine an authentication error when the authentication server fails to complete the authentication procedure within a critical time after the authentication server receives the authentication request from the user;

create a first authentication number in response to the authentication error;

transmit the first authentication number to the user;

receive a second authentication number from the robotaxi; and

transmit a request to unlock a door to the robotaxi when the first authentication number and the second authentication number match; and

the robotaxi configured to:

receive the second authentication number from the user;

transmit the second authentication number to the authentication server; and

unlock the door in response to the request to unlock from the authentication server.

2 . The system of claim 1 , wherein the robotaxi is configured to receive the second authentication number from the user via a touch keypad of the robotaxi.

3 . The system of claim 2 , wherein the touch keypad is located on an outer surface of a door window of the robotaxi.

4 . The system of claim 1 , wherein the robotaxi includes a sensor configured to receive biometric information of the user.

5 . The system of claim 1 , wherein the robotaxi includes a call button configured to connect the user to a customer service center.

6 . The system of claim 5 , wherein the call button is located on a B pillar of the robotaxi.

7 . A method for authenticating a user of a robotaxi, the method comprising:

receiving an authentication request from the user that has a valid digital key;

performing an authentication procedure in response to the authentication request;

determining an authentication error when the authentication procedure fails to complete within a critical time;

creating, by an authentication server, a first authentication number in response to the authentication error;

transmitting, by the authentication server, the first authentication number to the user;

receiving, by the robotaxi, a second authentication number from the user;

transmitting, by the robotaxi, the second authentication number to the authentication server;

transmitting, by the authentication server, a request to unlock a door to the robotaxi when the first authentication number and the second authentication number match; and

unlocking, by the robotaxi, the door in response to the request to unlock from the authentication server.

8 . The method of claim 7 , wherein receiving, by the robotaxi, the second authentication number from the user includes receiving the second authentication number from the user through a touch keypad located on an exterior surface of the robotaxi.

9 . The method of claim 7 , wherein transmitting, by the authentication server, the first authentication number to the user comprises transmitting, by the authentication server, the first authentication number to a smart phone of the user.

10 . The method of claim 7 , further comprising receiving, by the robotaxi, biometric information of the user.

11 . The method of claim 7 , further comprising connecting, by the robotaxi, the user to a customer service center in response to a user request received at a call button of the robotaxi.

12 . The method of claim 11 , wherein the call button is located on a B pillar of the robotaxi.

13 . An authentication system comprising:

an authentication server; and

a robotaxi that includes a call button located on an exterior of the robotaxi;

wherein the authentication server is configured to:

authenticate a user based on reference biometric information of the user and biometric information transmitted from the robotaxi;

create a first authentication number in response to the user being authenticated based on the biometric information;

receive a second authentication number from the robotaxi; and

transmit a request to unlock a door to the robotaxi when the first authentication number and the second authentication number match; and

wherein the robotaxi is configured to:

receive a user input at the call button on the exterior of the robotaxi;

receive the biometric information of the user;

transmit the biometric information of the user to the authentication server;

provide the first authentication number to the user in response to the user input at the call button;

receive the second authentication number from the user;

transmit the second authentication number to the authentication server; and

unlock the door in response to the request to unlock from the authentication server.

14 . The system of claim 13 , wherein the authentication server is configured to:

receive an authentication request from the user that has a valid digital key;

perform an authentication procedure in response to the authentication request; and

determine an authentication error when the authentication server fails to complete the authentication procedure within a critical time after the authentication server receives the authentication request from the user.

15 . The system of claim 13 , wherein the call button is located on a B pillar of the robotaxi.

16 . The system of claim 13 , wherein the robotaxi includes a sensor configured to receive the biometric information of the user.

17 . The system of claim 16 , wherein the robotaxi includes a touch keypad configured to receive the second authentication number from the user.

18 . The system of claim 17 , wherein the touch keypad is located on an outer surface of a door window of the robotaxi.

19 . The system of claim 13 , wherein the robotaxi is configured to provide the first authentication number to the user via an audio communication.

20 . A method of authenticating the user of the robotaxi of claim 13 , the method comprising:

receiving, by the robotaxi, the user input at the call button on the exterior of the robotaxi;

receiving, by the robotaxi, the biometric information of the user;

transmitting, by the robotaxi, the biometric information of the user to the authentication server;

authenticating, by the authentication server, the user based on the reference biometric information of the user and the biometric information transmitted from the robotaxi;

creating, by the authentication server, the first authentication number when the user is authenticated;

providing, by the robotaxi, the first authentication number to the user;

receiving, by the robotaxi, the second authentication number from the user;

transmitting, by the robotaxi, the second authentication number to the authentication server;

receiving, by the authentication server, the second authentication number from the robotaxi;

transmitting, by the authentication server, the request to unlock the door to the robotaxi when the first authentication number and the second authentication number match; and

unlocking, by the robotaxi, the door to the robotaxi in response to receiving the request to unlock from the authentication server.
