Vehicle Interface Access Control via Server-Based Application Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a centralized and intelligent mechanism to manage and control the extension of mobile phone applications onto vehicle head units, failing to ensure safe and appropriate access to vehicle interfaces based on vehicle conditions and user preferences.
Innovation Solution
A network device maps application operation modes to vehicle conditions and compares application identifiers to determine authorized access to specific vehicle interface components, using remote server software to control and prioritize access, ensuring safe and intelligent utilization of vehicle interfaces.

Engineering Contradiction Analysis
1Illumination intensity
If mobile phone applications are extended to the vehicle head unit, then user interface quality is improved, but vehicle safety is compromised due to unrestricted access to interface components
Solution Approach 1:
The patent implements selective access control where different applications are granted permission to access specific subsets of vehicle interface components based on their functionality and safety requirements. For example, navigation applications may access display and audio components while gaming applications are restricted during driving. This localized permission system allows high-quality interface usage where safe while preventing harmful access where risky.
Solution Approach 2:
The patent introduces a server-based intermediary system that acts as a mediator between mobile applications and vehicle interface components. The server receives application requests, evaluates them against safety criteria and vehicle conditions, and grants or denies access permissions. This intermediary layer enables comprehensive interface access when appropriate while blocking potentially harmful access, thus resolving the contradiction between interface quality and safety.
2Object-affected harmful factors
If centralized server control is implemented to manage application access, then vehicle safety is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-establishing safety policies, application profiles, and interface component mappings on the server before runtime operations. Applications are pre-evaluated and assigned permission sets based on their intended functionality. During actual operation, the system only needs to enforce these pre-determined policies rather than making complex safety decisions in real-time, thus improving safety while minimizing runtime complexity.
3Object-affected harmful factors
If application access to vehicle interface is restricted based on vehicle conditions, then safety is improved, but user experience deteriorates
Solution Approach 1:
The patent implements dynamic access control where application permissions are not fixed but change based on real-time vehicle conditions. For example, when the vehicle is stationary, applications may access all interface components freely. When the vehicle transitions to moving mode, the system dynamically adjusts permissions to restrict access to safety-critical components while maintaining access to non-distracting functions. This dynamic adaptation preserves safety while optimizing user experience for each operational context.

AI summary
In one example, a network device (322) signals control software (330) on a vehicle to permit a particular application to access only an identified portion of the vehicle interface (321). The network device (322) probes the control software (330) or the vehicle interface (321) to correlate the vehicle interface (321) to a particular one of a plurality of vehicle interface configurations (369A, 369B). The network device causes the vehicle interface (321) to display a particular one (381) of a plurality of graphical user interfaces based on a result of said probing.
