Solution Overview

Problem

Existing display control systems for vehicles fail to clearly indicate whether a lane change to an adjacent lane is permissible, leading to ambiguity for occupants.

Innovation Solution

A display control system that uses color changes in lane partition lines to indicate lane change permission, restricting display of adjacent lane partition lines when a lane change is not allowed, and allowing full display when it is permissible, based on route deviation and specific regulations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the display shows all adjacent lane partition lines, then the display provides complete lane information, but the occupant cannot understand whether lane change is permitted

Engineering Contradiction:
Improvelane change permission informationVSAvoiddisplay control logic
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies color changes to partition lines to indicate lane change permission status. When lane change is permitted, the partition line is displayed in a first color (e.g., white); when lane change is prohibited, the partition line is displayed in a second color (e.g., red). This visual color coding allows occupants to immediately understand whether lane change is permitted without complex text or icons, directly resolving the information loss problem while maintaining simple control logic.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent segments the display information by treating each partition line independently with its own color state. Instead of displaying a single unified lane view, each adjacent lane's partition line is individually colored based on lane change permission status. This segmentation allows the system to convey multiple pieces of information (which lanes exist, which allow lane changes) simultaneously without increasing overall display complexity.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the display shows partition lines for all adjacent lanes, then the display provides comprehensive lane information, but it creates ambiguity about lane change permission

Engineering Contradiction:
Improvelane change guidance accuracyVSAvoidoccupant understanding
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses color changes to eliminate ambiguity about lane change permission. Partition lines are displayed in a first color when lane change is permitted and in a second color when prohibited. This creates an intuitive visual language where occupants can immediately understand which lanes are safe to change into, significantly improving ease of operation and understanding while maintaining reliable lane change guidance.

Inventive Principle:
Principle #32Color changes

3Loss of information

If the display always shows adjacent lane partition lines, then the display maintains consistent information presentation, but it fails to convey lane change permission status

Engineering Contradiction:
Improvelane change permission statusVSAvoiddisplay structure
Core Design Contradiction:
Loss of informationVSStability of the object's composition

Solution Approach 1:

The patent maintains the stable display structure of always showing partition lines for consistency, while overlaying color changes to convey lane change permission status. The partition lines remain visually present and structurally stable, but their color dynamically changes to indicate permission status. This approach preserves display structure stability while effectively communicating lane change permission information without losing any critical data.

Inventive Principle:
Principle #32Color changes

AI summary

A display control device includes a display that is configured to display information and a display controller that is configured to cause the display to display a plurality of partition lines for partitioning a host lane in which a vehicle is present and an adjacent lane adjacent to the host lane, and the display controller is configured to cause the display to display a partition line of the adjacent lane in a case where the adjacent lane is a lane in which a lane change from the host lane is possible, and restrict causing the display to display the partition line of the adjacent lane in a case where the adjacent lane is not a lane in which a lane change from the host lane is possible.
