Autonomous Vehicle Passenger Entry Using Icon-Based Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ride-hailing for autonomous vehicles faces challenges in reliable and safe passenger authentication and entry, particularly due to the proximity of other vehicles and users, which complicates quick and confident identification and access.
Innovation Solution
The system employs a processor in the autonomous vehicle to receive information from a mobile device, transmitting a graphical icon to the user's device to indicate arrival, allowing the user to unlock the vehicle by dragging the icon into a receptacle, and also uses biometric information, PIN pads, and teleoperation calls for secure entry, with different communication channels for long-range and short-range interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used, then security can be maintained, but the authentication process becomes slow and unreliable in the presence of multiple vehicles and users
Solution Approach 1:
The system creates a visual copy (graphical icon) of the vehicle on the user's mobile device screen. This digital representation allows the user to identify and authenticate with the correct vehicle remotely, eliminating the need for physical proximity or manual verification processes, thus reducing authentication time while maintaining reliability through visual confirmation.
Solution Approach 2:
The system introduces a mobile device as an intermediary between the user and the vehicle authentication process. The mobile device displays the graphical icon and transmits authentication data, serving as a mediator that enables reliable and quick authentication without requiring direct interaction between the user and the vehicle in crowded environments.
2Adaptability or versatility
If multiple authentication methods are provided, then security and adaptability are improved, but device complexity increases
Solution Approach 1:
The mobile device serves multiple functions: it displays the graphical icon for vehicle identification, captures biometric data, transmits authentication information, and communicates with the vehicle system. By making the mobile device universal and multi-functional, the system avoids adding separate dedicated devices for each authentication method, thereby maintaining versatility while controlling overall system complexity.
3Productivity
If visual identification methods are used, then authentication speed is improved, but reliability may be compromised in crowded environments with multiple similar vehicles
Solution Approach 1:
The graphical icon displayed on the mobile device provides localized and specific visual information about the particular vehicle the user has requested. Rather than requiring the user to visually scan and differentiate between multiple physical vehicles in the environment, the system delivers targeted visual identification data directly to the user's device, ensuring both speed and accuracy by eliminating environmental distractions and similar-vehicle confusion.
Data Source
AI summary
Methods, apparatus, and systems for passenger authentication and entry for autonomous vehicles are disclosed. A vehicle receives information over a first communication channel from a first mobile device. The information specifies a geographical location. The information causes the vehicle to arrive at the geographical location. The vehicle transmits a first message to a second mobile device indicating that the vehicle has arrived at the geographical location. The first message includes a graphical icon representing the vehicle. The graphical icon is for display on a user interface of the second mobile device. The vehicle receives a second message from the second mobile device over a second communication channel. The second message indicates that the graphical icon was dragged across the user interface into a graphical receptacle displayed on the user interface. Responsive to receiving the second message, at least one door of the vehicle is unlocked.
