Vehicle Interface Device Switching Data Transmission Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle data transmission modes (VDTM) face challenges in maintaining optimal data transfer rates due to interference, increased distance, and changes in communication channels, leading to suboptimal performance in displaying vehicle data.
Innovation Solution
A device, such as a vehicle interface device (VID), is configured to detect triggers and switch between multiple VDTM based on conditions, determining the appropriate mode to ensure maximum data transfer rates by adjusting data transmission parameters and prioritizing data messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the communication link operates at maximum data transfer rate, then data transmission efficiency is improved, but the system becomes more vulnerable to interference and channel changes
Solution Approach 1:
The system dynamically switches between two vehicle data transmission modes (VDTM1 and VDTM2) based on real-time communication conditions. The processor monitors triggers such as interference levels, distance changes, and channel variations, then selectively activates the appropriate transmission mode to maintain optimal data transfer while ensuring reliable communication
Solution Approach 2:
The system changes transmission parameters by switching between different VDTM configurations. Each mode has distinct data transmission characteristics, and the processor modifies the active mode based on detected conditions, thereby adjusting transmission behavior to match current communication environment requirements
2Adaptability or versatility
If the device switches transmission modes frequently to adapt to changing conditions, then adaptability is improved, but system complexity increases
Solution Approach 1:
The communication system is segmented into two distinct transmission modes (VDTM1 and VDTM2), each optimized for specific communication conditions. This segmentation allows the system to handle different scenarios with predefined modes rather than implementing complex continuous adjustment logic, thereby improving adaptability while controlling system complexity
Solution Approach 2:
The processor continuously monitors communication conditions and uses this feedback to determine when to switch between VDTM1 and VDTM2. The feedback mechanism triggers mode switching only when specific conditions are met, providing adaptive behavior with relatively simple control logic based on predefined trigger conditions

AI summary
A vehicle interface device (VID) switches to a first vehicle data transmission mode (VDTM) from a prior VDTM based on a trigger for transmitting vehicle data messages (VDMs) and which VDMs have been requested at a vehicle data receptor (VDR). A decreased data transfer rate may result from selecting the first VDTM such that some portions of VDMs received while the VID is operating in the other VDTM are transmitted to the VDR from the VID and other portions of those VDMs are not transmitted to the VDR from the VID. An increased data transfer rate may result from selecting the first VDTM such that some portions of VDMs received while the VID is operating in the first VDTM are transmitted to the VDR from the VID whereas those same portions would not have been transmitted to the VDR from the VID if the VID was still operating in the prior VDTM.
