Curved-Road Surface Projection Control for Driver Focus Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road surface rendering technologies do not effectively enhance driving safety for vehicles, particularly when traveling along curved roads, as the projected images can distract drivers by being rendered away from the point ahead on the curve.
Innovation Solution
A vehicle system that adjusts the projected road surface images to move from a reference position in front of the vehicle to an inside position on a curve by controlling light projection using a projection member and circuitry, ensuring the images remain relevant to the driver's focus on the road ahead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If road surface rendering is performed at a reference position in front of the vehicle, then the rendering function can provide driving information to the driver, but when traveling along a curved road the rendered image is positioned away from the driver's focus point causing distraction
Solution Approach 1:
The patent applies dynamics by making the rendering position adjustable rather than fixed. The control unit dynamically changes the rendering position on the road surface based on the vehicle's steering angle and curvature detection, allowing the rendered image to move with the driver's focus point during curved road traversal, thereby maintaining both safety and ease of operation
Solution Approach 2:
The patent implements feedback by using a curvature detection unit to continuously monitor road curvature and a steering angle detection unit to track driver input. This feedback information is fed to the control unit, which adjusts the rendering position in real-time to keep the rendered image aligned with the driver's focus point, resolving the contradiction between providing driving information and avoiding distraction
2Productivity
If the projected image is positioned away from the driver's focus point on a curved road, then the rendering can be displayed on the road surface, but it creates distraction and reduces effectiveness
Solution Approach 1:
The system dynamically adjusts the rendering position based on real-time detection of road curvature and steering angle. By making the rendering position adaptive rather than static, the system ensures the rendered image remains positioned at the driver's focus point during curved road traversal, thereby maintaining high rendering effectiveness while eliminating driver distraction
Solution Approach 2:
The patent changes the positional parameters of the rendered image based on detected road conditions. The control unit modifies the rendering position coordinates according to steering angle and curvature data, ensuring the image remains optimally positioned for driver visibility and relevance, thus improving productivity while reducing harmful distraction effects

Function Achieved in This Case
Improves driving safety by ensuring projected images are rendered closer to the driver's focus point on a curved road, reducing distraction and enhancing the effectiveness of road surface rendering.
Implementation Method 1
a projection member configured to perform light projection for road surface rendering to a road surface at least forward from the vehicle
Data Source
AI summary
A vehicle with a road surface rendering function includes a projection member and a controller. The projection member is configured to perform light projection for road surface rendering to a road surface at least forward from the vehicle. The controller is configured to control the light projection for the road surface rendering by the projection member. The controller is configured to, when the vehicle is traveling along a curved road, adjust a road surface rendering image to be rendered on the road surface by projecting light from the projection member to move the road surface rendering image from a reference rendering position in front of the vehicle when the vehicle is traveling along a straight road toward an inside of a curve of the curved road.
