Innovation Solution
A system and method that enables the development of third-party applications by generating APIs based on vehicle signals and specifications, allowing developers to create vehicle-specific functions through a vehicle communication network, using a protocol analysis mode and API packaging module within a software development kit SDK.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a third-party application development system is introduced to enable custom applications on mobile devices, then application functionality and user customization are improved, but system complexity and security management become worsened
Solution Approach 1:
The patent introduces a portal server as an intermediary between the mobile terminal and the application ecosystem. The portal server manages application distribution, authentication, and execution environments, isolating the complexity from the mobile device while enabling rich application functionality. This mediator handles security policies, application installation, and runtime management, resolving the contradiction between versatility and system complexity.
2Adaptability or versatility
If third-party applications are allowed on mobile devices, then application diversity is improved, but security risks and unauthorized access become worsened
Solution Approach 1:
The portal server acts as a security intermediary that authenticates third-party applications before deployment to mobile terminals. It verifies application credentials, manages digital signatures, and controls application execution permissions. This intermediary layer enables application diversity while maintaining security by filtering and managing all third-party applications centrally.
Solution Approach 2:
The system implements feedback mechanisms where the portal server continuously monitors application behavior, user authentication status, and security events. When security policies are violated or unauthorized access attempts occur, the portal server can revoke application permissions, update security policies, or notify users, creating a dynamic feedback loop that maintains security while allowing application diversity.
3Speed
If application installation and execution are managed locally on mobile devices, then installation speed is improved, but network dependency and centralized control become worsened
Solution Approach 1:
The portal server performs preliminary actions by pre-processing applications, verifying their security credentials, and preparing installation packages before transmission to mobile terminals. This preliminary authentication and preparation work reduces the computational burden on mobile devices during installation and execution, enabling faster local deployment while maintaining centralized security control through pre-validated application packages.

AI summary
The present disclosure discloses a system and a method for developing a third-party application. The system includes: a vehicle-mounted device and a developer platform communicating with each other. The vehicle-mounted device generates a corresponding API according to a protocol analysis mode of a vehicle signal and API specifications, adds the API to a software development kit SDK, and sends the API to the developer platform. The developer platform publishes the SDK so that a developer can develop a third-party application according to the API in the SDK.
