Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The conventional AUTOSAR (CP) protocol is inadequate for modern vehicles with intelligent networking and autonomous driving technologies, as it cannot communicate with AP devices using DDS, requiring manual code modifications and lacking service-oriented communication capabilities.

Innovation Solution

A system architecture integrating DDS into the CP software architecture through a first integrated module that manages message publishers and subscribers, enabling automatic discovery and data management without modifying underlying software components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If DDS is implemented in CDD in CP software architecture, then service-oriented communication capability is improved, but device complexity and manual code modification increase

Engineering Contradiction:

Improveservice-oriented communication capabilityVSAvoidmanual code modification

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The DDS communication middleware is nested within the BSW layer of the CP software architecture, allowing DDS functionality to be integrated into the existing AUTOSAR structure without requiring separate implementation layers. This nesting enables service-oriented communication while maintaining the standard development workflow

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The BSW layer is enhanced to provide both traditional AUTOSAR communication services and DDS service-oriented communication capabilities through a unified architecture. This multi-functionality allows the same software layer to support multiple communication paradigms without increasing overall system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If CP device uses only SOME/IP for communication, then compatibility with conventional architecture is maintained, but communication capability with AP devices using DDS is lost

Engineering Contradiction:

Improvecompatibility with conventional architectureVSAvoidcommunication capability with AP devices

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The BSW layer acts as an intermediary between the SWC layer and the communication network, supporting both SOME/IP and DDS protocols. This mediator approach allows CP devices to maintain compatibility with conventional SOME/IP-based systems while simultaneously enabling communication with AP devices using DDS, without requiring changes to the SWC layer

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If DDS interfaces are manually added and modified, then DDS communication functionality is achieved, but development efficiency decreases

Engineering Contradiction:

ImproveDDS communication functionalityVSAvoiddevelopment efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system enables automatic code generation for DDS communication functionality through the BSW layer. Configuration files and parameters can be automatically processed to generate the necessary DDS interface code, eliminating the need for manual code addition and modification. This self-service approach maintains DDS communication functionality while significantly improving development efficiency

Inventive Principle:

Principle #25Self-service
