Server-Mediated Vehicle Authentication for Cross-Vehicle Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems, such as software-defined vehicles, increase security risks and inconvenience for users who frequently switch vehicles, as updated functions are not universally accessible without additional payments, and there is no effective mechanism to ensure that only paying users can utilize additional features across different vehicles.
Innovation Solution
A vehicle system that communicates with a server to identify users and vehicles, acquires function information based on user and vehicle data, and enables or disables functions accordingly, ensuring only paying users can access additional features across different vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle functions are updated independently in each vehicle, then the vehicle can provide customized services, but security risks increase and users experience inconvenience when switching vehicles
Solution Approach 1:
The patent introduces a server as an intermediary between the user and multiple vehicles. The server manages function information and authentication centrally, allowing the same function to be consistently accessed across different vehicles without increasing security risks. The server acts as a mediator that coordinates function permissions and user authentication across the vehicle fleet.
Solution Approach 2:
The patent implements a universal function information management system where function permissions are not tied to specific vehicles but are managed centrally. This allows a user's function access rights to be universally applied across multiple vehicles, eliminating the need for separate function updates in each vehicle while maintaining security through centralized control.
2Ease of operation
If function information is managed separately in each vehicle, then implementation is simple, but users who frequently switch vehicles experience inconvenience and cannot access updated functions
Solution Approach 1:
The server serves as an intermediary that handles function information management centrally. This eliminates the complexity of synchronizing function updates across multiple vehicles while providing users with convenient access to their authorized functions regardless of which vehicle they are using. The server automatically manages the complexity of function permission verification.
Solution Approach 2:
The system implements feedback mechanisms where the vehicle reports its current function status to the server, and the server responds with updated function information. This feedback loop ensures that users automatically gain access to updated functions when switching vehicles without manual intervention, improving user convenience while the server manages the complexity of coordination.
3Reliability
If there is no authentication mechanism for function access, then the system is simple to operate, but there is no way to ensure only paying users can utilize additional features
Solution Approach 1:
The server acts as an intermediary authentication authority that verifies user payment status and function access rights before allowing function utilization. This centralized authentication mechanism ensures only paying users can access additional features while the server manages the complexity of authentication logic, keeping the vehicle systems relatively simple.
Solution Approach 2:
The system performs preliminary authentication of user payment status and function permissions before allowing access to paid features. The server pre-verifies user credentials and function rights in advance, ensuring secure access control without adding complex authentication steps at the point of function usage in the vehicle.

AI summary
A vehicle is communicatively connected to a server via a network, and includes: a first acquirer that acquires user information for identifying a user; a storage that stores vehicle information for identifying the vehicle; a transmitter that transmits the user information acquired and the vehicle information stored in the storage to the server; a second acquirer that acquires, from the server, function information indicating one or more functions that are identified based on the user information and the vehicle information, are performable by the vehicle, and are permitted to be utilized by the user; and a controller that enables the one or more functions indicated by the function information.
