Narrow-Road Driving Assistance Control for Oncoming Vehicle Passing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle traveling control systems fail to effectively handle situations where a host vehicle and an oncoming vehicle attempt to pass each other on a narrow road, leading to potential contact and inability to navigate narrow roads safely.
Innovation Solution
A traveling control device that includes a driving assistance ECU to announce alerts to occupants of vehicles when a narrow road is detected, adjusting the alert content based on vehicle positions and surroundings, and determining priority based on estimated entry times to avoid narrow-road passes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the host vehicle autonomously drives to pass the oncoming vehicle on a narrow road, then the host vehicle can pass the oncoming vehicle without driver intervention, but the likelihood of contact between the host vehicle and the oncoming vehicle increases
Solution Approach 1:
The system applies preliminary anti-action by announcing alerts to occupants before the vehicles reach the narrow road section. The alert notification is sent in advance to both the host vehicle and the other vehicle, prompting occupants to take preventive actions (such as slowing down or stopping) before entering the narrow road, thereby avoiding the harmful situation of contact
Solution Approach 2:
The system introduces an intermediary alert notification mechanism that mediates between the autonomous driving control system and the vehicle occupants. This intermediary alert system communicates the potential conflict situation to the occupants, allowing them to manually intervene or adjust their behavior to prevent contact, thus bridging the gap between automated control and human decision-making
2Extent of automation
If the host vehicle autonomously drives on a narrow road, then the host vehicle can pass the oncoming vehicle without driver intervention, but the system cannot handle situations where both vehicles attempt to enter the narrow road simultaneously
Solution Approach 1:
The system implements feedback by continuously monitoring the positions and speeds of both the host vehicle and the other vehicle, and by sending alert notifications to occupants based on the detected situation. This feedback loop allows the system to adapt its behavior based on the real-time state of the narrow road situation, improving its ability to handle various scenarios including simultaneous entry attempts

AI summary
A traveling control device for a vehicle includes a driving assistance ECU configured to, when a determination is made that there is a possibility that a host vehicle will enter a narrow road with a road width less than a reference value and that the host vehicle will attempt to pass a second vehicle on the narrow road, announce, to at least one of an occupant of the host vehicle and an occupant of the second vehicle, an alert for avoiding a situation in which the host vehicle and the second vehicle pass each other on the narrow road.
