Engineering Contradiction Analysis
1Reliability
If actual vehicle tests are conducted with automatic driving functions, then tire performance data can be obtained under realistic driving conditions, but tire wear increases leading to frequent replacements and decreased testing efficiency
Solution Approach 1:
The controller dynamically adjusts driving parameters (speed, acceleration, steering angle) based on tire wear state and test progress. By changing these operational parameters in real-time, the system maintains reliable tire performance evaluation while reducing excessive wear that would otherwise require frequent tire replacements.
Solution Approach 2:
The system continuously monitors tire state and test conditions, then feeds this information back to the controller which adjusts driving commands accordingly. This closed-loop feedback mechanism ensures that tire wear is optimized to extend tire life while maintaining the reliability of performance data collection under realistic driving conditions.
2Productivity
If vehicle speed and steering are controlled to reduce tire load, then tire wear is reduced and testing efficiency improves, but the complexity of the control system increases
Solution Approach 1:
The controller performs multiple functions: it manages automatic driving navigation, monitors tire state, adjusts speed and steering commands, and optimizes tire load. By consolidating these diverse functions into a single control unit, the system reduces tire wear to improve testing efficiency without proportionally increasing overall system complexity.
Solution Approach 2:
The control system automatically adjusts driving parameters based on real-time tire state information without requiring external intervention. This self-service capability allows the system to optimize tire load and extend tire life while maintaining simple operational procedures for testers.
