Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle communication systems face challenges in balancing the reliability and cost of data communication, with wired communication providing higher reliability but at a higher cost and wireless communication compromising on reliability.
Innovation Solution
A wired-wireless hybrid communication system that uses a combination of wired and wireless interfaces to prioritize and segregate communication data based on priority, using a data priority information storage unit to determine whether communication data is transmitted via wired or wireless interfaces, optimizing data volume and reducing the need for expensive communication lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication is used for all communication devices, then reliability of data communication is improved, but cost increases due to expensive communication lines
Solution Approach 1:
The communication data is segmented into high-priority and low-priority categories based on importance. High-priority data is transmitted through wired communication channels for reliability, while low-priority data uses wireless channels for cost efficiency. This segmentation allows the system to achieve overall reliability for critical communications while reducing infrastructure costs through selective wireless usage.
2Ease of manufacture
If wireless communication is used to reduce costs, then cost decreases, but reliability of data communication deteriorates
Solution Approach 1:
Different communication channels are assigned different quality characteristics based on local requirements. Critical communication paths use high-reliability wired connections, while non-critical paths use cost-effective wireless connections. The system dynamically selects the appropriate communication mode for each data type, ensuring that reliability is maintained where needed while achieving cost savings where possible.
3Reliability
If all communication devices are connected through expensive communication lines, then reliability is improved, but device complexity and infrastructure cost increase
Solution Approach 1:
Communication devices are equipped with multi-functionality, capable of both wired and wireless communication modes. This universal capability allows each device to adapt its communication method based on data priority and channel availability, reducing the need for dedicated expensive wired infrastructure for all devices while maintaining reliability for critical communications.

AI summary
A wired-wireless hybrid communication system and a wired-wireless hybrid communication method perform control such that, of the types of communication data transmitted and received between communication devices provided in a vehicle, wired communication is used for high-priority communication data and wireless communication is used for low-priority communication data. Specifically, wired communication data and wireless communication data divided based on the priority defined for each type of the communication data are separately transmitted via wired communication and wireless communication, and the wired communication data and the wireless communication data separately received at the received side are combined to reconstruct the communication data.
