Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used for remote vehicle control, then accessibility and convenience are improved, but data latency increases
Solution Approach 1:
The system performs preliminary actions by predicting the vehicle's future trajectory and state based on current sensor data and vehicle dynamics models. This allows the remote operator to receive anticipatory information about vehicle conditions before they actually occur, compensating for communication latency. The predictive trajectory adjustment pre-calculates control commands based on predicted future states, ensuring timely and accurate remote control despite time delays in data transmission.
2Speed
If high-speed wireless networks are used, then data transmission speed is improved, but reliability in remote areas without cellular networks deteriorates
Solution Approach 1:
The communication system is designed with multi-functionality to operate across different network environments. It can automatically switch between high-speed wireless networks (5G mmWave) when available and alternative communication methods when operating in remote areas without cellular coverage. This universal communication capability ensures both high data transmission speed in urban areas and reliable operation in remote locations, making the system adaptable to various deployment scenarios.
3Ease of operation
If remote vehicle operation is enabled, then driver accessibility is improved, but control precision deteriorates due to latency
Solution Approach 1:
The system implements comprehensive feedback mechanisms that continuously monitor vehicle sensor data, environment sensor data, and control command execution. This real-time feedback loop allows the remote operator to accurately perceive vehicle state and make precise control adjustments. The feedback is enhanced with predictive information about future vehicle states, enabling the operator to compensate for latency and maintain high control precision despite the physical distance from the vehicle.
