Autonomous Driving Automation Level Switching Under Real-Time Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous driving systems are unable to adaptively control automation levels in real-time, requiring drivers to wait until specific conditions are met before resuming autonomous driving, which can lead to inconvenience and safety issues.
Innovation Solution
A method and device that collect state recognition information during travel, determine the currently applicable maximum automation level, and adjust it downward or upward based on driver requests and environmental conditions, allowing for continuous autonomous driving without deactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous driving system waits for operation conditions to be satisfied before performing autonomous driving, then the safety and reliability of autonomous driving is improved, but the productivity and driver convenience deteriorates due to waiting time
Solution Approach 1:
The automation level is made dynamic and adjustable rather than fixed. The system can switch between different automation levels (e.g., level 2 to level 3) based on real-time assessment of operation conditions, allowing the degree of automation to adapt to current environmental and system states.
Solution Approach 2:
The system changes the parameter of automation level to resolve the contradiction. By adjusting the automation level parameter based on whether operation conditions are met, the system can provide higher automation when conditions allow and lower automation when conditions are not favorable, thus balancing safety and convenience.
2Productivity
If the automation level is adjusted downward to currently applicable maximum level when conditions are not met, then the productivity and continuous operation is improved, but the extent of automation deteriorates
Solution Approach 1:
The automation level is dynamically adjusted based on real-time conditions. When operation conditions are not fully met, the system automatically transitions to a lower automation level that can still operate safely under current conditions, enabling continuous operation without complete deactivation.
Solution Approach 2:
Instead of requiring full satisfaction of all operation conditions for autonomous driving, the system performs partial automation at a reduced level. This allows the vehicle to operate with diminished automation capabilities rather than stopping entirely, thus maintaining productivity.
3Reliability
If the system performs manual travel until operation conditions are satisfied, then the reliability is improved by ensuring conditions are met, but the loss of time increases
Solution Approach 1:
The system dynamically transitions between different operation modes (manual travel, partial automation, full automation) based on the satisfaction of operation conditions. When conditions are not met, it operates at a lower automation level rather than waiting, thus reducing time loss while maintaining reliability through appropriate mode selection.
Solution Approach 2:
The system performs preliminary assessment of operation conditions and proactively adjusts the automation level accordingly. Rather than waiting for conditions to become favorable, it prepares and executes operation at an appropriate automation level based on current conditions, reducing unnecessary waiting time.

AI summary
A method and a device for controlling autonomous driving in an autonomous driving vehicle are provided. The method may include collecting state recognition information during travel, receiving information on a driver-requested automation level, determining a currently applicable maximum automation level based on the collected state recognition information, comparing the driver-requested automation level with the currently applicable maximum automation level to determine whether automation level downward adjustment is required, and adjusting an automation level downward to perform the autonomous driving when it is determined that the automation level downward adjustment is required.
