Vehicle Deceleration Support Point Exclusion Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deceleration support systems unintentionally perform deceleration support when road changes reduce the necessity for deceleration at registered deceleration points, leading to unnecessary support execution.
Innovation Solution
A support point management system that acquires and excludes deceleration support points based on vehicle travel data, determining if a new road has been constructed by analyzing travel patterns and road shape changes, and adjusting support flags accordingly to prevent unnecessary deceleration support.

Engineering Contradiction Analysis
1Reliability
If deceleration support is performed at frequently visited deceleration points, then deceleration support can be learned and provided at common locations, but unnecessary deceleration support is unintentionally performed when road changes reduce the necessity for deceleration
Solution Approach 1:
The system monitors whether the vehicle actually decelerates at registered deceleration points and uses this feedback to determine if the point should remain registered. When the vehicle passes through a registered deceleration point without decelerating, this negative feedback triggers exclusion of the point from future deceleration support, allowing the system to adapt to changing road conditions and driver preferences.
Solution Approach 2:
The deceleration point registration is made dynamic rather than static. The system continuously updates the status of deceleration points based on recent travel behavior, excluding points where the vehicle has recently passed without deceleration. This dynamic adjustment allows the system to respond to road changes and maintain high accuracy in providing necessary deceleration support while avoiding unnecessary interventions.
2Adaptability or versatility
If deceleration points are registered based on frequent deceleration operations, then the system can learn common deceleration locations, but the system cannot adapt when road shape changes make deceleration unnecessary
Solution Approach 1:
The system uses feedback from actual vehicle behavior (whether deceleration occurs at registered points) to continuously update the deceleration point database. This feedback mechanism ensures that outdated information is automatically removed when road conditions change, maintaining high adaptability without requiring manual updates or complex road map change detection.
Solution Approach 2:
The system performs self-updating by automatically detecting when registered deceleration points are no longer necessary based on vehicle travel patterns. Instead of requiring external input about road changes, the system uses its own operational data to identify and exclude obsolete deceleration points, achieving continuous adaptation through self-service.

AI summary
Support point management systems, methods, and programs acquire a support point registered as a subject of deceleration support and exclude the support point as the subject of deceleration support in a case a vehicle travels on a new road after having traveled through the support point without deceleration at the support point.
