Driving Assistance Visibility Check for Safe Overtaking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems fail to consider visibility when a driver attempts to pass a preceding vehicle, leading to a risk of collision with oncoming vehicles due to poor visibility conditions such as curves, fog, or snow, as they do not adequately detect or prevent entering the opposite lane.
Innovation Solution
A driving assistance device equipped with a processor that determines if visual recognition within a predetermined distance is possible, using sensors and map information, and warns or controls the vehicle to avoid entering the opposite lane when visibility is poor, thereby preventing collisions with oncoming vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle enters the opposite lane to pass a preceding vehicle, then the passing maneuver is completed, but the risk of collision with oncoming vehicles increases when visibility is poor
Solution Approach 1:
The system performs preliminary visibility assessment before allowing lane change by determining whether visual recognition within a predetermined distance can be achieved. This preliminary check prevents entering the opposite lane when visibility is poor, thereby reducing collision risk before the passing maneuver begins
Solution Approach 2:
The driving assistance device acts as an intermediary between the driver's passing intention and the actual lane change execution. It detects operations causing the vehicle to enter the opposite lane and intervenes by warning or controlling the vehicle to prevent entry when visibility is insufficient, thus mediating between passing efficiency and collision risk
2Ease of operation
If the driver operates the vehicle to enter the opposite lane without visibility consideration, then the passing maneuver can be initiated, but undetected oncoming vehicles may cause collision
Solution Approach 1:
The system provides feedback to the driver about visibility conditions before and during the passing maneuver. By determining whether visual recognition is possible and providing warnings when visibility is poor, the system creates a feedback loop that informs the driver of undetected oncoming vehicle risks without completely restricting passing operations
Solution Approach 2:
The system applies preliminary anti-action by detecting operations to enter the opposite lane and preemptively warning or preventing the maneuver when visibility is poor. This counteracts the driver's passing intention before it leads to dangerous lane entry, addressing the harmful factor of undetected oncoming vehicles

AI summary
A driving assistance device includes a visibility determination unit that determines whether visual recognition within a predetermined distance from a vehicle can be achieved in a traveling direction of the vehicle, an operation detection unit that detects an operation of causing the vehicle to enter a space in which an oncoming vehicle travels, based on information representing an operation of the vehicle by a driver, and a control warning unit that warns the driver or controls the vehicle in such a way that the vehicle does not enter the space when the visibility determination unit determines that visual recognition within the predetermined distance cannot be achieved, and the operation detection unit detects the operation of causing the vehicle to enter the space.
