The autonomous vehicle utilizes feedback from a passenger mobile device to determine network indicators such as signal strength, bandwidth, and latency, allowing it to switch to a more favorable network operator, thereby optimizing connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the autonomous vehicle switches between mobile network operators without prior knowledge of network conditions, then the vehicle can potentially access different networks, but the switching process becomes time-consuming and results in suboptimal connections
Solution Approach 1:
The system performs preliminary network condition assessments by utilizing feedback from passenger mobile devices before the autonomous vehicle commits to a network switch. Mobile devices provide advance information about signal strength, bandwidth, and latency of available networks, allowing the vehicle to make informed switching decisions without time-consuming trial-and-error approaches
Solution Approach 2:
The system implements a feedback mechanism where passenger mobile devices continuously report network conditions (signal strength, bandwidth, latency) to the autonomous vehicle's network selector. This real-time feedback enables the vehicle to identify optimal networks before switching, reducing unnecessary downtime and ensuring connectivity quality
2Reliability
If the autonomous vehicle switches networks frequently to seek better connectivity, then the vehicle can potentially maintain optimal connection quality, but the frequent switching causes additional downtime and instability
Solution Approach 1:
Before initiating a network switch, the system uses mobile device feedback to pre-assess target network conditions. This preliminary evaluation ensures that switches are only performed when the target network demonstrably offers superior connectivity, preventing unnecessary switching that would disrupt connection stability
Solution Approach 2:
The continuous feedback loop from mobile devices provides real-time network condition data, enabling the system to make stable, informed decisions about when to switch networks. The system only switches when feedback indicates a significant improvement is available, maintaining connection stability while ensuring quality
3Productivity
If the autonomous vehicle uses passenger mobile device feedback for network selection, then the vehicle can optimize connectivity by switching to better networks, but the system requires additional communication infrastructure with passenger devices
Solution Approach 1:
Passenger mobile devices automatically provide network condition feedback to the autonomous vehicle without requiring additional manual configuration or complex communication protocols. The system leverages the existing capabilities of mobile devices to serve the network selection function, reducing the need for specialized hardware or complex software infrastructure
Solution Approach 2:
The system utilizes the existing multi-functional capabilities of passenger mobile devices (which already communicate with the vehicle for other purposes) to also provide network condition feedback. This approach avoids adding dedicated communication infrastructure by making existing devices serve multiple functions

AI summary
Systems and techniques are provided for an autonomous vehicle (AV) to select a mobile network. An example method can include establishing a connection between the AV and a mobile device associated with a passenger of the AV; identifying, using the connection, a first mobile network associated with the mobile device; determining that the first mobile network associated with the mobile device is different than a second mobile network associated with the AV; determining, based on a first network indicator associated with the first mobile network and a second network indicator associated with the second mobile network, that the first mobile network is preferable to the second mobile network; and initiating a mobile connection between the AV and the first mobile network.
