Driving Assistance Sign Notification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving assistance systems fail to accurately notify drivers of traffic signs when the road changes due to turns, leading to potential misinformation and unsafe driving conditions.
Innovation Solution
A driving assistance apparatus that includes a sign recognizing unit and a notification executing unit, which stops notifying drivers of sign information when the vehicle slows down and a turn indicator is operated, ensuring that only current traffic sign information is displayed, preventing uncertain information from being presented to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the recognition result of traffic signs is continuously displayed on the monitor, then the driver can always see sign information, but the driver may receive inaccurate or outdated sign information when the road changes due to turns
Solution Approach 1:
The notification execution unit dynamically adjusts the display of sign information based on real-time vehicle state (turn indicator operation and vehicle speed). When a turn is detected, the system transitions from continuous display to selective display, stopping notification of signs that may no longer be relevant to the current road section, thereby maintaining information accuracy during dynamic driving conditions
Solution Approach 2:
The system uses feedback from the turn indicator operation and vehicle speed sensors to determine whether to continue displaying sign information. This closed-loop control ensures that the monitor only displays sign information when the vehicle is traveling straight at appropriate speeds, preventing display of outdated information while maintaining continuous display during normal conditions
2Adaptability or versatility
If the system displays all recognized traffic signs, then comprehensive sign information is provided, but uncertain or outdated information may be presented when the vehicle is turning
Solution Approach 1:
The system adaptively adjusts the comprehensiveness of displayed sign information based on vehicle dynamics. During straight-line travel, all recognized signs are displayed comprehensively. During turns (detected via turn indicator and speed), the system selectively stops displaying signs that may no longer apply, maintaining adaptability to current driving conditions while ensuring reliability of presented information

AI summary
A driving assistance apparatus includes a sign recognizing unit and a notification executing unit. The sign recognizing unit recognizes a traffic sign from an image captured by an on-board imaging apparatus. The notification executing unit notifies a driver of sign information that is information indicated by the traffic sign recognized by the sign recognizing unit. Based on a vehicle speed of the own vehicle and operating information of a turn indicator of the own vehicle under a condition that the driver is being notified of the sign information, the notification executing unit stops notifying the driver of the sign information.
