Solution Overview
Problem
Existing communication systems for vehicles struggle to dynamically determine and adjust communication priority levels based on the vehicle's location and network availability, leading to inefficient data transmission and potential disruptions during vehicle control operations.
Innovation Solution
A communication device and system that dynamically determines communication priority levels by switching between cellular and Wi-Fi networks based on the vehicle's location, using on-board instruments to acquire status information and adjust communication protocols accordingly, ensuring continuous high-speed and low-delay data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication priority level is determined statically or not dynamically adjusted, then device complexity is reduced, but communication reliability deteriorates during network switching
Solution Approach 1:
The patent implements dynamic determination of communication priority levels based on real-time network conditions and vehicle status. The determination unit dynamically adjusts priority levels when switching between first communication system (e.g., cellular) and second communication system (e.g., Wi-Fi), ensuring optimal communication reliability adapted to changing environments rather than using static priority assignments.
Solution Approach 2:
The patent employs feedback mechanisms where the determination unit continuously monitors network switching events and communication status, then adjusts priority levels accordingly. The communication control unit receives feedback about network conditions and vehicle status, enabling closed-loop control that maintains reliability while managing complexity through intelligent decision-making.
2Reliability
If communication priority level is dynamically adjusted based on network conditions, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent divides the communication device into distinct functional units: a determination unit responsible for priority level determination and a communication control unit responsible for executing communication based on those priorities. This segmentation allows complex determination logic to be isolated from communication execution, managing overall system complexity while maintaining high reliability through specialized function blocks.
Solution Approach 2:
The determination unit serves multiple functions: it determines priority levels for both first and second communication systems, handles network switching decisions, and adapts to various vehicle statuses. This multi-functionality reduces the need for separate specialized components, managing complexity while achieving reliable communication across diverse scenarios.
3Loss of information
If communication switches between different access points without priority level adjustment, then ease of operation is maintained, but loss of information occurs during switching
Solution Approach 1:
The determination unit determines the appropriate communication priority level in advance before network switching occurs. By pre-determining priority levels based on anticipated network conditions and vehicle status, the system ensures seamless transitions between access points without information loss, while the automated nature of this preliminary action maintains ease of operation.
Solution Approach 2:
The determination unit acts as an intermediary between network switching events and communication execution. It mediates the transition by determining appropriate priority levels that ensure continuous, loss-free data transmission during switching between first and second communication systems, while the communication control unit executes the switched communication based on these determined priorities.
