Autonomous Driving Handover Control Based on Driver State Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic driving systems lack a mechanism to safely transition from autonomous driving to manual driving, as they do not effectively assess a driver's recovery ability, leading to potential accidents and traffic disruptions when drivers are fatigued or unable to manually intervene.
Innovation Solution
An automatic driving control device and method that determines a driver's state using various sensors and monitors, allowing safe switching between autonomous and manual driving modes by assessing the driver's ability to recover to manual control, preventing unsafe transitions through warnings and automatic interventions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic driving mode is activated to reduce driver burden, then driver fatigue is reduced, but driver recovery ability deteriorates
Solution Approach 1:
The system performs preliminary assessment of the driver's state before allowing mode switching. The determination unit evaluates whether the driver has sufficient recovery ability before transitioning from automatic driving to manual driving, preventing unsafe transitions before they occur
Solution Approach 2:
The system continuously monitors driver state and provides feedback through the notification unit. When the driver's state is assessed as insufficient for manual driving, the system notifies the driver and prevents mode switching, creating a closed-loop safety mechanism
2Speed
If mode switching is allowed without assessment to improve responsiveness, then switching speed increases, but safety decreases
Solution Approach 1:
The determination unit continuously assesses driver state in advance, so when mode switching is requested, the assessment is already complete or can be quickly finalized, minimizing delay while ensuring safety
Solution Approach 2:
The system automatically performs the safety assessment and mode switching decision without requiring manual intervention from the driver, maintaining rapid response while ensuring safety criteria are met

AI summary
A method for switching modes for operating a vehicle, a non-transitory computer-readable medium for performing the method, and information processing apparatuses. The method includes determining, by circuitry of an information processing apparatus, whether a mode for operating the vehicle is to be switched from one of autonomous and manual driving modes to the other of the autonomous and manual driving modes. A state of a driver of the vehicle is obtained when the mode for operating the vehicle is determined to be switched. The method further includes switching, by the circuitry, the mode for operating the vehicle from the one of the autonomous and manual driving modes to the other of the autonomous manual driving modes based on the obtained state of the driver.
