In-Vehicle Display Control for Lane Change Line Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle display systems intermittently block the display of adjacent lane dividing lines due to vehicles obstructing the view, causing driver annoyance.
Innovation Solution
An in-vehicle display system that includes a camera and an electronic control unit (ECU) to recognize lane dividing lines and control display timing, displaying an icon for the outer dividing line only during lane changes and not when the vehicle is not changing lanes, thereby reducing driver annoyance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dividing line of the adjacent lane is displayed continuously on the display screen, then the driver can always see the lane information, but the display becomes intermittent and annoying when the dividing line is blocked by a vehicle
Solution Approach 1:
The display system dynamically adjusts the display behavior based on the host vehicle's lane change state. When a lane change is detected, the system displays the outer dividing line icon continuously; when no lane change is occurring, the icon is not displayed. This dynamic adaptation resolves the contradiction by showing information only when necessary for the current driving maneuver.
Solution Approach 2:
The system performs preliminary detection of the lane change state before displaying the dividing line icon. The lane change state detection unit identifies when the host vehicle is executing a lane change maneuver, and only then does the display control unit show the outer dividing line icon. This preliminary action ensures the icon is displayed proactively before potential blocking occurs.
2Loss of information
If the system displays the outer dividing line icon during lane changes, then lane change visibility is improved, but the display complexity increases
Solution Approach 1:
The display system is segmented into distinct functional units: a lane change state detection unit that monitors lane change conditions, and a display control unit that manages icon display based on detection results. This segmentation allows each unit to perform its specific function independently, reducing overall system complexity while improving lane information visibility during lane changes.

AI summary
An in-vehicle display system includes a dividing line recognition unit configured to recognize dividing lines of an adjacent lane adjacent to a host vehicle lane, on which a host vehicle is traveling, on the basis of a detection result of a camera of the host vehicle and a display control unit configured to control display on a display on the basis of a recognition result of the dividing line recognition unit. The display control unit displays, on the display, an icon corresponding to a dividing line away from the host vehicle lane among the dividing lines of the adjacent lane when the host vehicle starts a lane change from the host vehicle lane to the adjacent lane and does not display the icon corresponding to the dividing line on the display when the host vehicle does not start the lane change.
