Driver-Set Warning Timing in Driving Assistance Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems do not adequately consider a driver's intention when providing warnings, leading to varying levels of acceptance among drivers, with some finding warnings annoying and others wanting proactive assistance.
Innovation Solution
A driving assistance system that includes an assistance information acquisition unit, a setting information acquisition unit, and a driving assistance unit, which provides assistance based on assistance information generated by an assistance information generation device, considering the assistance timing set by the driver, and only provides assistance when the timing is within a predetermined range, thereby respecting the driver's intention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving assistance warnings are provided proactively to all drivers, then safety assistance is improved, but driver acceptance deteriorates due to annoyance
Solution Approach 1:
The system divides drivers into different groups based on their warning acceptance characteristics. By acquiring driver information and determining acceptance levels, the system applies different warning strategies to different drivers - providing proactive warnings to those who accept them while suppressing warnings for those who find them annoying, thus tailoring the assistance quality to each driver's preferences
Solution Approach 2:
The system changes the parameter of warning output timing based on driver acceptance characteristics. For drivers with high acceptance, warnings are provided earlier (proactively), while for drivers with low acceptance, warnings are suppressed or delayed, thereby optimizing the balance between safety assistance and driver comfort
2Reliability
If driving assistance is provided based on assistance information, then assistance effectiveness is improved, but driver intention consideration deteriorates when timing does not match driver preferences
Solution Approach 1:
The system acquires driver information that reflects driver intentions and preferences regarding warning timing. This feedback is used to adjust the warning output strategy, creating a closed-loop system where the assistance adapts to driver responses and preferences, thereby maintaining both effectiveness and adaptability
Solution Approach 2:
The system dynamically adjusts the warning output timing based on acquired driver information. Rather than using a fixed timing strategy, the system modifies its behavior according to individual driver characteristics, making the assistance adaptive and versatile while maintaining effectiveness

AI summary
A driving assistance system includes an assistance information acquisition unit configured to acquire assistance information from an information processing server, a setting information acquisition unit configured to acquire an assistance timing of an in-vehicle driving assistance unit set by a driver of a target vehicle, and an assistance information providing unit configured to execute driving assistance for the target vehicle based on the acquired assistance information. The assistance information providing unit provides the driving assistance based on the assistance information when the assistance timing is within a first timing range and does not execute the driving assistance based on the assistance information when the assistance timing is within a second timing range later than the first timing range.
