Driving Assistance Notification Inhibition at Stop Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems frequently alert drivers when a leading vehicle starts moving, causing annoyance in situations where vehicles are queuing up prior to a stop point, leading to frequent notifications as the leading vehicle stops and starts until the own vehicle passes through.
Innovation Solution
A driving assistance apparatus with a detector to identify when the leading vehicle has started moving and a notifier that inhibits notifications when the own vehicle approaches a stop point, using a combination of imaging, millimeter wave sensors, and navigation to determine the presence of queuing vehicles and adjust notification thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the notifier provides a notification whenever the leading vehicle starts moving, then the driver is informed of leading vehicle movements, but the driver experiences annoyance due to frequent notifications in stop-point queuing situations
Solution Approach 1:
The notification system applies different notification behaviors to different spatial locations. When the own vehicle is approaching a stop point (detected via GPS coordinates matching pre-stored stop point data), the notifier is inhibited from providing notifications even if the leading vehicle starts moving. This local differentiation resolves the contradiction by providing accurate notifications in normal situations while suppressing annoying notifications in stop-point queuing situations.
2Speed
If the notification system monitors leading vehicle movements continuously, then the driver receives timely information, but the system complexity increases due to stop point detection and inhibition logic
Solution Approach 1:
The system performs preliminary action by pre-storing stop point location data in advance. During actual operation, the notifier simply compares current GPS coordinates with the pre-stored stop point data to determine whether to inhibit notifications. This approach maintains fast notification response while minimizing system complexity by avoiding complex real-time analysis of traffic patterns or vehicle queuing behaviors.

AI summary
In a driving assistance apparatus, a detector is configured to detect whether or not a leading vehicle has started moving, where the leading vehicle is a vehicle just in front of an own vehicle and the own vehicle is a vehicle carrying the apparatus. A notifier is configured to, if it is detected by the detector that the leading vehicle has started moving, provide a notification that the leading vehicle has started moving. An inhibitor is configured to, when the own vehicle has approached a stop point along a road, at which every vehicle must stop before passing therethrough, inhibit the notifier from providing the notification that the leading vehicle has started moving.
