Vehicle Open API Gateway for Secondary Function Development
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles lack the ability for secondary development of functions after leaving the factory, limiting their adaptability and customization capabilities for users.
Innovation Solution
Incorporating an intelligent driving control module with an open API, connected through a security gateway, allowing third-party developers to perform secondary development without redeveloping the bottom layer, enabling intelligent control of vehicle systems and functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicles have fixed functions after leaving the factory, then the vehicle structure and control systems remain simple and stable, but the adaptability and customization capabilities are limited
Solution Approach 1:
The control system is segmented into multiple independent ECUs (Electronic Control Units), each responsible for specific vehicle functions. The open API gateway is segmented as a separate service that mediates between third-party applications and underlying ECU systems, allowing secondary development without complicating individual ECU architectures.
Solution Approach 2:
An open API gateway service is introduced as an intermediary layer between third-party developers and the vehicle's underlying control systems. This gateway provides standardized interfaces and protocols, enabling developers to access vehicle functions without directly interacting with complex bottom-layer systems, thus maintaining system stability while enabling customization.
2Ease of manufacture
If third-party developers perform secondary development without open APIs, then they can access vehicle functions, but they must redevelop the bottom layer increasing development cost and time
Solution Approach 1:
The vehicle manufacturer pre-establishes a standardized open API gateway service and unified communication protocols before third-party development begins. Common access paths, authentication mechanisms, and data formats are predetermined and documented, allowing developers to start secondary development immediately without investing time in bottom-layer protocol development or system integration.
Data Source
AI summary
A vehicle including an intelligent driving control module is provided. The intelligent driving control module is connected to each system in the vehicle through a security gateway of the vehicle, and the intelligent driving control module has an open application programming interface (API). The open API is a data interface for a third-party developer to perform secondary development. After the third-party developer performs secondary development on the vehicle by using the open API, the intelligent driving control module obtains state data of the vehicle through the security gateway and intelligently controls the vehicle according to the state data.
