Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous driving control is continuously maintained when passing through consecutive intersections, then automation level is improved, but safety and reliability deteriorate due to exceeding system capabilities
Solution Approach 1:
The patent implements dynamic adjustment of automation level based on real-time driving conditions. The control device monitors whether the vehicle is passing through consecutive intersections and automatically switches between autonomous driving control (higher automation) and manual driving control (lower automation) accordingly. This dynamic adaptation allows the system to maintain high automation levels when conditions permit while switching to manual control when reliability concerns arise, thus resolving the contradiction between automation extent and system reliability.
2Reliability
If autonomous driving control is switched to manual driving at consecutive intersections, then safety is improved, but ease of operation deteriorates due to frequent mode switching
Solution Approach 1:
The patent segments the driving route into distinct zones based on intersection patterns. When consecutive intersections are detected, the system identifies this as a specific scenario and applies targeted control adjustments. By segmenting the problem space (identifying consecutive intersection scenarios) and applying specific control logic to these segments, the system maintains safety in critical areas while preserving ease of operation in normal driving conditions, thus resolving the contradiction between safety and ease of operation.
3Device complexity
If a single threshold value is used for autonomous driving control switching, then device complexity is reduced, but adaptability deteriorates due to inability to handle different intersection scenarios
Solution Approach 1:
The patent applies local quality by implementing different control parameters and threshold values for different driving scenarios. Instead of a single universal threshold, the system adjusts control parameters specifically for consecutive intersection scenarios versus normal driving scenarios. This localized adaptation allows the system to maintain simplicity in normal conditions while enhancing adaptability for specific challenging scenarios, thus resolving the contradiction between device complexity and adaptability.
