Driving Assistance Control for Autonomous Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to assist drivers in making appropriate decisions about switching between autonomous driving and driver-operated driving based on the surrounding vehicle conditions, as existing systems lack effective methods to determine when it is safer to switch between these modes.
Innovation Solution
A driving assistance device and system that acquires autonomous driving information from nearby vehicles, calculates the autonomous driving ratio, and provides notifications to the driver on whether to switch to autonomous driving or maintain driver-operated control, using a combination of GPS, communication units, and display/voice output systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous driving is performed, then productivity is improved, but reliability deteriorates when surrounding vehicles are manually operated
Solution Approach 1:
The notification device provides feedback to the driver about the autonomous driving ratio of surrounding vehicles, enabling the driver to make informed decisions about switching between autonomous and manual driving modes based on the operational environment
Solution Approach 2:
The system dynamically adjusts the recommended driving mode based on real-time conditions by calculating the autonomous driving ratio of surrounding vehicles and providing context-aware notifications to the driver
2Ease of operation
If the driver switches to autonomous driving, then ease of operation is improved, but reliability deteriorates in environments with manually operated vehicles
Solution Approach 1:
The notification device provides advance information to the driver about the autonomous driving ratio before the driver decides to switch modes, allowing the driver to anticipate potential safety issues and make proactive decisions
Solution Approach 2:
The system continuously monitors and notifies the driver about the operational status of surrounding vehicles, providing real-time feedback that influences the driver's mode selection decisions
3Reliability
If the driver performs manual driving, then reliability is improved through direct control, but productivity deteriorates due to increased driver workload
Solution Approach 1:
The notification device provides feedback that helps the driver determine when manual driving is necessary, reducing unnecessary manual intervention while maintaining safety when needed
Solution Approach 2:
The system changes the operational parameters by providing information about the autonomous driving ratio, which influences the driver's decision-making process and optimizes the balance between manual and autonomous driving
4Ease of operation
If autonomous driving is performed in environments with low autonomous driving ratio, then ease of operation is improved, but reliability deteriorates due to lack of synchronization
Solution Approach 1:
The notification device warns the driver in advance about low autonomous driving ratio environments before the driver switches to autonomous mode, allowing the driver to prevent potential synchronization issues by staying in manual mode
Solution Approach 2:
The system takes preliminary action by notifying the driver of potential hazards (low autonomous driving ratio) before the actual problem occurs, enabling the driver to take preventive measures

AI summary
A driving assistance device is the driving assistance device used in a vehicle capable of switching between autonomous driving and driving that requires operation by the driver, and includes a different vehicle information acquisition unit that acquires autonomous driving information on different vehicles on a traveling road of the vehicle, an autonomous driving ratio acquisition unit that acquires a ratio of autonomous driving in the different vehicles from the autonomous driving information on the different vehicles acquired by the different vehicle information acquisition unit, and a notification control unit that provides information for supporting determination on switching between autonomous driving and driving that requires operation by a driver if the ratio of autonomous driving in the different vehicles is equal to or larger than a predetermined ratio.
