Vehicle Control System Rolling Border Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems face challenges in cross-border operations due to complex and costly software reconfigurations, which can disrupt essential vehicle functions and require multiple approvals, leading to risks of conflicting software implementations.
Innovation Solution
A system with a non-resettable first vehicle bus for maintaining stable control devices and a resettable second vehicle bus for reconfigurable control devices, allowing for seamless functionality changes during rolling transitions between regions, ensuring continuous operation and simplified software management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If reconfiguration of control software is performed during rolling border crossing, then cost savings in vehicle registration are achieved, but essential vehicle functions may become unavailable during the transition period
Solution Approach 1:
The control devices are divided into two distinct groups: first control devices that maintain stable operation throughout the border crossing, and second control devices that are reconfigured during the transition. This segmentation allows software updates in one region without affecting the stability of critical functions in another region, resolving the contradiction between cost savings through reconfiguration and reliability during transition.
Solution Approach 2:
The system dynamically adjusts the operational state of different control device groups based on the vehicle's location. During normal operation, all control devices function normally. During a rolling border crossing, the system transitions the first control devices to a stable maintenance mode while allowing the second control devices to be reconfigured, enabling continuous operation with updated software without compromising essential functions.
2Adaptability or versatility
If dedicated hardware for each destination country is used, then vehicle functionality can be adapted to different countries, but device complexity increases
Solution Approach 1:
Instead of using dedicated hardware for each country, the patent employs universal control devices that can operate in multiple countries. The control devices are designed to maintain stable operation across different regions, with software reconfiguration handled through the two-group architecture rather than hardware changes. This universal approach provides country-specific adaptability without increasing hardware complexity.
3Adaptability or versatility
If monolithic software containing all functions for all countries is used, then vehicle operation in multiple countries is enabled, but software complexity and approval difficulty increase
Solution Approach 1:
The software is segmented into two functional groups corresponding to the two groups of control devices. The first group maintains stable, approved software throughout the transition, while the second group undergoes reconfiguration for different countries. This segmentation reduces software complexity by separating stability-critical functions from region-specific functions, making the approval process more manageable while maintaining multi-country operation capability.
