Innovation Solution
A system and method for autonomous vehicles to perform performance checks on detection systems, map data, and vehicle components by navigating along a test route, collecting data, and comparing it with stored values to select an operation mode based on check results, allowing for timely preparation and efficient fleet management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive performance checks are conducted on detection systems and vehicle components, then safety and reliability are improved, but time consumption and operational delays increase
Solution Approach 1:
The system performs performance checks on detection systems and vehicle components before the vehicle begins its operational route. By conducting these checks preliminarily at designated locations along the planned route, the system ensures safety and reliability are verified in advance, preventing delays during actual operation while maintaining comprehensive inspection coverage.
Solution Approach 2:
The autonomous vehicle autonomously performs its own performance checks without requiring external human intervention. The vehicle navigates to designated check locations, executes self-diagnosis of detection systems and components, and determines its own operational status, thereby reducing time consumption while maintaining thorough safety verification.
2Measurement precision
If multiple performance checks are performed on detection systems, map data, and vehicle components, then measurement precision and safety are improved, but device complexity and operational complexity increase
Solution Approach 1:
The performance check system is divided into multiple independent check modules, each dedicated to specific detection systems or vehicle components. This segmentation allows each module to perform specialized measurements with high precision while keeping individual module complexity manageable. The system executes relevant check modules based on the vehicle's operational status and environmental conditions.
Solution Approach 2:
The system dynamically adjusts which performance checks are executed based on changing parameters such as environmental conditions, vehicle operational status, and location. By selectively activating only the necessary checks rather than performing all possible checks uniformly, the system maintains high measurement precision for critical parameters while reducing overall system complexity and computational burden.
