Engineering Contradiction Analysis
1Speed
If advanced wireless network technology is adopted to increase connection speed and device capacity, then network speed and device connectivity are improved, but network range is reduced and individual device performance deteriorates due to limited resources
Solution Approach 1:
The routing system dynamically adjusts vehicle routes based on real-time wireless network performance data. The route composition is not static but adapts continuously as network conditions change, allowing the system to optimize for both speed and range by selecting paths with adequate signal coverage while maintaining high connectivity speeds where available.
Solution Approach 2:
The system changes routing parameters (path selection, sequence of locations) based on varying network performance parameters. By monitoring metrics like signal strength, data throughput, and connection stability, the system adjusts the route parameters to maintain optimal balance between network speed and coverage area.
2Quantity of substance
If more mobile devices connect to a single wireless access point to increase network capacity, then device connectivity is improved, but network performance for each device decreases due to bandwidth sharing
Solution Approach 1:
The routing system segments the overall journey into multiple path segments, each evaluated for its network performance characteristics. By dividing the route and assigning different segments to different wireless networks based on their capacity and current load, the system ensures that no single access point becomes overloaded, maintaining adequate bandwidth for each vehicle.
Solution Approach 2:
The routing system acts as an intermediary between vehicles and wireless networks, mediating resource allocation by selecting optimal networks and time windows for connections. This intermediary function prevents direct contention for bandwidth by distributing vehicles across multiple networks and time slots, ensuring sufficient performance for each connected device.
3Productivity
If wireless network resources are allocated to support high-speed applications, then application functionality is improved, but network performance for other devices is reduced
Solution Approach 1:
The system performs preliminary evaluation of wireless network performance data before finalizing the route. By assessing network capabilities, signal coverage, and expected performance in advance, the system can plan routes that guarantee adequate network resources for driving assistance applications, preventing performance degradation by avoiding congested or inadequate networks from the outset.
Solution Approach 2:
The routing system incorporates feedback mechanisms that continuously monitor actual network performance during vehicle operation. This feedback loop allows the system to detect when network performance drops below required thresholds and dynamically adjust the route or switch to alternative networks, ensuring sustained functionality of driving assistance applications while maintaining fairness to other network users.

AI summary
Systems and methods for vehicle routing may be based on wireless network performance data. A vehicle route includes one or more path segments included in the route based on the wireless performance data. The vehicle route may be updated based on updated wireless performance data. Driving assistance features of a vehicle may be enabled by the wireless performance data, and different driving assistance features may be enabled or disabled on the vehicle route according to changes in wireless performance data. As the vehicle traverses the route, the driving assistance features may be enabled or disabled based on the wireless performance data for the path segment. The vehicle route may be updated to continue to enable a set of the driving assistance features.
