Vehicle Communication Device Adaptive Rule Base Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods between vehicles and remote servers fail to adapt to temporary changes in network coverage, such as outages, and are often costly due to data volume-based billing.
Innovation Solution
A communication device for vehicles equipped with multiple communication means and a rule base that regularly updates to select the most suitable communication method based on surroundings, including checking for updates, downloading and installing new rules, and transmitting data to a remote server for geolocation and operational feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3G or 4G connection is used to transfer data from vehicle to server, then data transmission is enabled, but cost increases due to volume-based billing
Solution Approach 1:
The system dynamically changes communication parameters by selecting different communication means (Wi-Fi, 3G, 4G, 5G) based on network conditions, data priority, and cost considerations. The rule base evaluates multiple parameters including network availability, data volume, and billing models to optimize the selection of communication means, thereby reducing costs while maintaining transmission capability.
Solution Approach 2:
The communication system is designed to be dynamic by continuously monitoring network conditions and adapting the selection of communication means in real-time. The rule base can be updated remotely to reflect changing network environments, allowing the system to respond dynamically to cost variations and network availability changes.
2Device complexity
If static communication selection method is used, then device complexity is reduced, but adaptability to network changes deteriorates
Solution Approach 1:
The system implements feedback mechanisms by transmitting data about communication performance and network conditions back to the server. The server uses this feedback to update the rule base, which is then downloaded to the vehicle terminal. This closed-loop feedback system enables continuous improvement of communication selection without requiring complex local decision-making logic.
Solution Approach 2:
The server acts as an intermediary that centralizes the complexity of communication selection logic. Instead of embedding complex adaptive algorithms in each vehicle terminal, the server maintains and distributes the rule base, simplifying the onboard device while maintaining high adaptability through centralized intelligence.
3Device complexity
If rule base is not updated regularly, then device complexity is reduced, but communication effectiveness deteriorates due to outdated selection criteria
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing optimal communication selections in the rule base before they are needed. The server proactively updates the rule base based on accumulated network data and environmental information, so that when the vehicle terminal needs to select a communication means, optimized rules are already available, eliminating the need for complex real-time calculations.
