In-Vehicle Content Display Restriction for Cut-In Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles equipped with automatic driving functions, drivers may experience anxiety during traffic congestion due to the potential for cut-in by adjacent vehicles, which existing systems fail to adequately address.
Innovation Solution
A presentation control device is implemented in vehicles with automatic driving functions, featuring a traffic congestion determination unit, a cut-in prediction unit, and a provision restricting unit. This device determines traffic congestion and predicts cut-in attempts by adjacent vehicles, thereby restricting the display of content during such conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is displayed during automatic travel period, then driver comfort and entertainment are improved, but driver anxiety increases when cut-in occurs
Solution Approach 1:
The system performs preliminary detection of cut-in signs (adjacent vehicle acceleration, lane change intentions) before the actual cut-in occurs. When signs are detected, the system proactively restricts content display to prevent driver anxiety, rather than waiting for the cut-in to happen. This anticipatory approach maintains driver comfort while preventing harmful anxiety.
Solution Approach 2:
The system continuously monitors traffic congestion conditions, adjacent vehicle behaviors, and driver state, then provides feedback by adjusting content display restrictions. When cut-in signs are detected or traffic congestion is identified, the system feedback-loop restricts content display, and when conditions normalize, it restores content provision, dynamically balancing comfort and safety.
2Object-affected harmful factors
If content display is restricted during traffic congestion, then driver anxiety is reduced, but driver entertainment and comfort deteriorate
Solution Approach 1:
The system dynamically adjusts content display restrictions based on real-time traffic conditions, adjacent vehicle behaviors, and detected cut-in signs. Rather than applying static restrictions, the system modulates content provision according to the current driving situation, restricting content only when necessary (during detected cut-in signs or traffic congestion) and allowing it during safe periods, thus minimizing impact on driver comfort.
3Productivity
If automatic driving function is activated during traffic congestion, then driving efficiency is improved, but safety monitoring by driver decreases
Solution Approach 1:
The system performs preliminary detection of cut-in signs and traffic congestion conditions before they become critical threats. By detecting adjacent vehicle acceleration, lane change intentions, or congestion patterns in advance, the system can alert the driver or restrict content display proactively, ensuring safety monitoring is maintained even when the driver is engaged with content during automatic driving.

AI summary
A traffic congestion determination unit is configured to determine whether a traffic congestion occurs in an automatic travel period in which the vehicle travels by an automatic driving function. A cut-in prediction unit is configured to detect a sign of cut-in of an adjacent vehicle, which is adjacent to a subject vehicle as the vehicle, on determination by the traffic congestion determination unit that a traffic congestion occurs. A provision restricting unit is configured to restrict display of content provided in the automatic travel period on detection of a sign of cut-in of the adjacent vehicle by the cut-in prediction unit.
