Lane Change Guide Indication for Automatic Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During automatic lane changes in vehicles, drivers and passengers often experience awkwardness due to unclear guidance about the vehicle's intended direction, leading to discomfort and uncertainty.
Innovation Solution
A travel control device that includes a lane change control unit and a display control unit, which automatically guides the vehicle and provides visual indications on a display unit, showing the starting and finishing positions of the lane change, as well as lane keeping guide indications, to enhance clarity and reduce awkwardness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic lane change control is performed without guide indication, then the lane change operation is simple and fast, but the driver or passenger experiences awkwardness due to unclear vehicle heading information
Solution Approach 1:
A display unit is introduced as an intermediary between the automatic lane change control system and the driver/passenger. The display unit visually presents lane change information including the vehicle's current lane, destination lane, starting position, and finishing position, thereby compensating for the lack of direct sensory feedback during automated operation.
Solution Approach 2:
The system performs preliminary display of lane change information before the actual lane change execution. The guide indication is shown in advance to inform the driver or passenger about the intended vehicle movement, reducing awkwardness by providing foresight into the automated action.
2Loss of information
If guide indication is provided during automatic lane change, then driver or passenger awkwardness is reduced, but the device complexity increases due to additional display control unit
Solution Approach 1:
The display control unit is designed to perform multiple functions: displaying current lane information, destination lane information, starting position, and finishing position. This multi-functionality reduces the need for separate dedicated components for each type of information presentation, thereby mitigating the increase in device complexity.
3Loss of information
If detailed lane change information is displayed, then clarity and understanding are improved, but the information processing and display time increase
Solution Approach 1:
The lane change information is segmented into distinct visual elements: current lane indication, destination lane indication, starting position marker, and finishing position marker. This segmentation allows the display control unit to present comprehensive information in an organized, easily processable format that reduces cognitive load and processing time.

AI summary
In a case where automatic lane change control is performed, a traveling lane and another lane as a lane change destination are displayed on a display unit based on lane change information, and a guide indication of a lane change starting position or a lane change finishing position is displayed on the displayed traveling lane or the displayed another lane.
