In-Vehicle Display Layout for Lane-Change Distance Indicator Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle display devices cause discomfort to occupants when displaying a set vehicle-to-vehicle distance indicator during lane changes, as the indicator moves across lane markings, disrupting the visual experience.
Innovation Solution
An in-vehicle display device that adjusts the display of the vehicle-to-vehicle distance indicator and lane markings relative to the host vehicle icon during lane changes, ensuring the indicator is not shown until the lane change is completed, and displays a change-unavailable indicator during the operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the set vehicle-to-vehicle distance indicator is displayed in front of the host vehicle icon during lane change, then the driver can understand the set distance, but the occupant feels discomfort due to the indicator crossing lane markings
Solution Approach 1:
The display controller determines whether a lane change operation is being performed before displaying the distance indicator. When lane change is detected, the indicator is suppressed in advance, preventing the harmful visual effect of crossing lane markings while maintaining distance information availability through alternative means
2Duration of action of stationary object
If the set vehicle-to-vehicle distance indicator is continuously displayed during lane change, then the distance information remains visible, but the display creates visual disruption and discomfort
Solution Approach 1:
The display controller dynamically adjusts the visibility of the distance indicator based on the lane change operation state. The indicator is displayed when lane change is not being performed and suppressed when lane change is detected, creating an adaptive display behavior that eliminates visual disruption while maintaining information availability when appropriate
3Measurement precision
If the host vehicle icon moves across lane markings during lane change, then the lane change operation is accurately represented, but the distance indicator also crosses lane markings causing discomfort
Solution Approach 1:
The display controller extracts the distance indicator from the host vehicle icon during lane change operations. By separating the indicator display from the moving icon, the system maintains accurate representation of lane change through the icon's movement while eliminating the harmful effect of the indicator crossing lane markings

AI summary
An in-vehicle display device displays, on a display, a set vehicle-to-vehicle distance indicator indicating a set vehicle-to-vehicle distance of vehicle-to-vehicle distance control between a preceding vehicle and a host vehicle. The in-vehicle display device includes an operation determination unit configured to determine whether or not a lane change operation of the host vehicle is being performed, and a display controller configured to display, on the display, a host vehicle icon, a set vehicle-to-vehicle distance indicator displayed in front of the host vehicle icon, and a lane marking. The display controller is configured not to display the set vehicle-to-vehicle distance indicator until the lane change is completed when it is determined that the lane change operation of the host vehicle is being performed.
