Autonomous Vehicle Manual Mode Switching Under Traffic Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicles lack the ability to safely switch to manual driving mode without interfering with nearby vehicles, particularly in unpredictable driving environments, leading to potential collision risks.
Innovation Solution
An autonomous driving controller determines whether a driver requests switching to manual driving mode while driving or after stopping, and safely navigates the vehicle to a designated lane or place based on surrounding conditions, ensuring a safe transition by communicating with a control center to identify optimal lanes or places for switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If switching to manual driving mode is performed unconditionally regardless of surrounding driving environment, then ease of operation is improved, but safety deteriorates due to potential collision risks
Solution Approach 1:
The system performs preliminary safety verification by evaluating surrounding driving environment (vehicles in adjacent lanes, distance to front/rear vehicles) before allowing mode transition. This preliminary check ensures that switching to manual driving mode only occurs when it is safe to do so, preventing collisions while maintaining ease of operation.
2Reliability
If mode switching is restricted based on surrounding driving environment, then safety is improved, but ease of operation deteriorates due to additional constraints
Solution Approach 1:
The autonomous driving controller automatically performs safety verification and determines whether mode transition is permitted based on surrounding environment. This self-service approach eliminates the need for drivers to manually assess safety conditions, maintaining ease of operation while ensuring safety through automated environmental evaluation.
3Reliability
If the system verifies surrounding driving environment before mode switching, then safety is improved, but device complexity increases
Solution Approach 1:
The safety verification function is merged into the existing autonomous driving controller that already manages vehicle operation. By integrating environmental sensing and safety evaluation into the existing control architecture rather than adding separate systems, the patent improves safety while minimizing increases in device complexity.

AI summary
A method of controlling switching to a manual driving mode of an autonomous vehicle, enables switching to the manual driving mode to be safely performed without interfering with a nearby vehicle in a safe lane or a safe place according to a surrounding driving environment by allowing a driver to select between switching to the manual driving mode while driving or switching to the manual driving mode after stopping to switch to the manual driving mode while the autonomous vehicle is driven in an autonomous driving mode.
