Adaptable Vehicle Communication Logic for Component Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in vehicles struggle to adapt to new components integrated during operation, as the logic for information exchange is rigid and cannot be easily changed, leading to difficulties in controlling data access and content, especially with aftermarket components like cell phones and infotainment devices.
Innovation Solution
A communication system where the logic is designed to be adaptable based on the state and context of the system, using decentralized component filters and a set of rules that allow changing filter entries and prioritization, enabling flexible information exchange and content control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If logic is defined at component manufacturing time to control information exchange, then communication security is improved, but adaptability to new components deteriorates
Solution Approach 1:
The logic is transformed from a static configuration fixed at manufacturing time to a dynamic structure that can be modified during system operation. The logic now adapts to new components by allowing runtime additions and modifications, enabling the system to maintain security while accommodating aftermarket components and system state changes.
Solution Approach 2:
The logic is divided into modular components that can be independently managed. This segmentation allows specific logic rules to be added, modified, or removed without affecting the entire logic structure, facilitating easy adaptation to new components while preserving existing security constraints.
2Adaptability or versatility
If logic is changed via software updates to adapt to new components, then adaptability is improved, but maintenance time deteriorates
Solution Approach 1:
The logic modification capability is enabled during system operation rather than requiring external software updates. This dynamic approach allows logic to be adapted to new components in real-time, significantly reducing maintenance time while maintaining adaptability.
3Ease of manufacture
If logic checks only message routing information, then ease of implementation is improved, but content control capability deteriorates
Solution Approach 1:
The logic checking process is segmented into multiple independent evaluation stages. This segmentation allows the system to first check routing information for efficiency, then progressively evaluate content-specific constraints, thereby achieving both ease of implementation and comprehensive content control.
Solution Approach 2:
The logic performs partial content control by evaluating only the necessary portions of message content based on the communication context. This selective approach maintains ease of implementation while providing adequate content control for security-relevant scenarios.

AI summary
The system (40) has multiple components including a source component (42) and a destination component (43) that exchange information among each other. The exchanging of the information is limited by a logic that is changed depending on the condition of the system. The logic is designed in the form of a filter (51) and has a control equipment (48), where filter entries of the filter are changed based on the equipment. Independent claims are also included for the following: (1) a communication method for exchanging information between components that are connected with each other (2) components of a communication system for exchanging information with other components.
