User-Vehicle Authentication via Dual Wireless Protocols
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in interacting with passengers, including complex interactions for multiple pick-ups and drop-offs, climate, and lighting control, as well as coordinating with transit service systems, which can complicate the passenger experience and require unnecessary user interface systems within the vehicle.
Innovation Solution
A user device is used to initiate transit requests and authenticate with autonomous vehicles using different wireless communication protocols, establishing a direct wireless connection for controlling cabin settings and unlocking the vehicle, thereby reducing the need for interior user interfaces and optimizing vehicle hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple wireless communication protocols are used for authentication and control, then security and reliability are improved, but device complexity increases
Solution Approach 1:
The patent segments the authentication and control processes into distinct phases, each using a different wireless communication protocol. First authentication information is transmitted using a first protocol, then second authentication information and control instructions are transmitted using a second protocol. This segmentation allows each protocol to be optimized for its specific function while maintaining overall system security and reliability.
2Device complexity
If user interface systems within the vehicle are minimized, then device complexity is reduced, but ease of operation may worsen
Solution Approach 1:
The patent introduces a user device (such as a smartphone) as an intermediary between the user and the vehicle control system. The user device transmits control instructions to the vehicle via wireless communication, eliminating the need for complex physical interfaces within the vehicle while maintaining ease of operation through familiar mobile device interfaces.
Solution Approach 2:
The patent replaces mechanical and physical user interfaces within the vehicle with wireless electronic communication. Instead of requiring physical buttons, knobs, or displays inside the vehicle, all control operations are performed remotely through a user device using wireless communication protocols, thereby reducing vehicle hardware complexity.
3Reliability
If authentication processes are made more secure with multiple verification steps, then reliability is improved, but loss of time increases
Solution Approach 1:
The patent performs preliminary authentication actions by transmitting first authentication information before the actual vehicle access is required. This preliminary authentication establishes a secure foundation that enables faster subsequent access decisions, reducing the time loss during actual vehicle entry while maintaining high security standards.

AI summary
In some exemplary processes for accessing a vehicle, a transit request is initiated. The transit request summons a vehicle towards a location of a user device. Information generated in response to the transit request is received. The information includes first authentication information and second authentication information. Third authentication information from the vehicle is received using a first wireless communication protocol. A determination is made as to whether the third authentication information corresponds to the first authentication information. In accordance with determining that the third authentication information corresponds to the first authentication information, a wireless communication connection is established with the vehicle using a second wireless communication protocol and the second authentication information. The second wireless communication protocol is different from the first wireless communication protocol. Using the second wireless communication protocol, instructions to unlock a cabin of the vehicle are sent.
