Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle uses high-definition map navigation mode, then precise navigation and route planning are achieved, but the driver's control rights and driving freedom are reduced
Solution Approach 1:
The patent implements dynamic lane switching that adapts to driver intentions in real-time. The system transitions from static navigation routing to dynamic route adjustment by detecting driver operations (lever shifts, steering inputs) and automatically adjusting the navigation route to match driver intent, thereby maintaining precise navigation while restoring driver control freedom
Solution Approach 2:
The system incorporates feedback mechanisms by continuously monitoring driver operations and vehicle state, then adjusting the navigation route based on this feedback. When the driver performs operations indicating lane switching or route deviation, the system processes this feedback and automatically updates the navigation plan, creating a closed-loop control that balances automated precision with driver intent
2Reliability
If the vehicle follows fixed navigation routes, then accurate route guidance is provided, but the ability to handle complex scenarios like intersections is limited
Solution Approach 1:
The patent transforms fixed navigation routes into dynamic, adaptable paths. The system continuously evaluates the current navigation route against actual driver operations and environmental context, automatically adjusting the route when intersections or complex scenarios are detected, enabling the vehicle to handle diverse driving conditions while maintaining route guidance accuracy
Solution Approach 2:
The navigation system is segmented into multiple decision points, particularly at intersections. Instead of treating the route as a single fixed path, the system divides navigation into segments that can be independently adjusted based on local conditions such as intersection geometry, traffic patterns, and driver intent, enhancing adaptability to complex scenarios
3Measurement precision
If lane switching is restricted during navigation, then navigation accuracy is maintained, but driving flexibility and driver intent are compromised
Solution Approach 1:
The system uses feedback from driver operations to dynamically control lane switching permissions. When the driver performs operations indicating desired lane changes, the system processes this feedback and adjusts lane switching restrictions accordingly, allowing lane changes that align with driver intent while maintaining navigation accuracy for routes not driven by the driver
Solution Approach 2:
Lane switching restrictions are transformed from static constraints to dynamic controls. The system continuously adjusts lane switching permissions based on real-time detection of driver operations, enabling flexible lane changes when the driver initiates them while maintaining navigation accuracy for system-controlled segments

AI summary
An intelligent driving method causes a vehicle to perform roaming based on a high-definition map, where the roaming can include lane switching, driving direction changing, or partial navigation strategy changing. The vehicle may perform the lane switching, the driving direction changing, or the partial navigation strategy changing based on an operation of a driver.
