HD Map Driving Control for Lane Switching and Roaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intelligent vehicles lack the ability to roam freely based on high-definition maps, limiting driver control and navigation flexibility, especially in complex scenarios like intersections, and fail to allow lane switching or real-time adjustment of navigation strategies.
Innovation Solution
An intelligent driving method and apparatus that utilizes high-definition maps for precise navigation, enabling lane switching, intersection passing, and real-time partial navigation strategy changes, incorporating iterative forward search and driver habit costs to enhance vehicle autonomy and user control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle uses high-definition map navigation mode, then navigation precision is improved, but driving freedom and lane switching capability deteriorate
Solution Approach 1:
The patent implements dynamic lane switching capability within high-definition map navigation by allowing the vehicle to switch between navigation mode and roaming mode. The system dynamically adjusts the degree of automation and lane switching permission based on driver input (lever position) and road conditions, enabling the vehicle to transition from strict navigation following to more flexible roaming with lane switching capabilities while maintaining overall navigation guidance.
2Measurement precision
If the vehicle implements strict navigation route following, then route accuracy is improved, but driver control and real-time adjustment capability deteriorate
Solution Approach 1:
The patent applies partial automation by implementing a hybrid mode where navigation guidance is maintained for overall route accuracy, but lane switching and local maneuvering capabilities are partially restored through driver input. The system provides navigation assistance rather than full automation, allowing drivers to make real-time adjustments while the system maintains route accuracy through high-definition map guidance and corrective steering assistance.
3Reliability
If the vehicle operates in automated driving mode, then driving safety is improved, but driver intervention and emergency response capability deteriorate
Solution Approach 1:
The patent implements continuous feedback mechanisms where the system monitors driver input (lever position, steering angle) and vehicle state, then adjusts the level of automation and lane switching permission accordingly. The feedback loop allows the system to maintain safety through automated monitoring while preserving driver intervention capability by detecting driver intent and appropriately adjusting automation levels, enabling smooth transitions between fully automated and driver-controlled modes.

AI summary
An embodiment of this application provides an intelligent driving method. According to the intelligent driving method, a vehicle may perform roaming based on a high-definition map, where the roaming includes: lane switching, driving direction changing, or partial navigation strategy changing. The vehicle performs the lane switching, the driving direction changing, or the partial navigation strategy changing based on an operation of a driver, where the operation of the driver includes at least one of the following: lever shifting, voice control, button control, or gesture control.
