Vehicle Display Controller for Early Lane Change Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers cannot appropriately check road conditions when a vehicle is not approaching a point where road conditions change, leading to inadequate timing for assessing road shapes.
Innovation Solution
A display system that includes a recognizer to identify the vehicle's surroundings, a display to show road shapes, and a display controller to display images of added lanes when they are in the same direction as the vehicle's travel, along with guidance for lane changes based on route recommendations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display only shows road shapes when the vehicle approaches a point where road conditions change, then the display system maintains simple operation, but the driver cannot check road conditions at an appropriate timing
Solution Approach 1:
The display controller displays an image about the added lane (including marking information) before displaying the image representing the shape of the added lane. This preliminary display of lane information allows the driver to be aware of upcoming road conditions and lane changes in advance, enabling better timing for checking road conditions without waiting until the vehicle approaches the exact change point
2Loss of information
If the display shows all road markings continuously, then the driver can always check road conditions, but the display system becomes complex and information overload occurs
Solution Approach 1:
The display controller selectively displays information about added lanes (lanes in the same direction as vehicle travel) rather than all road markings. This localized approach focuses display resources on providing relevant road condition information about upcoming lane changes while maintaining simple display control logic
Solution Approach 2:
The system displays marking information about added lanes before displaying the actual shape of the lanes. This preliminary display of essential information allows drivers to understand upcoming road conditions without continuously displaying all possible road marking details, balancing information provision with display simplicity

AI summary
A display system includes a recognizer configured to recognize a surrounding situation of a vehicle, a display configured to display images, and a display controller configured to cause the display to display an image representing a road shape around the vehicle recognized by the recognizer, wherein, when a lane in which the vehicle can travel in the same direction as a travel direction of the vehicle is added, the display controller causes the display to display an image about the added lane outside the image representing the road shape on the side on which the lane is added before the display is caused to display an image representing a shape of the added lane.
