Vehicle Road Surface Image Rendering Dynamic Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing road surface image rendering technologies from vehicles can impair the rearward visibility of preceding vehicles due to reflected light, as they do not effectively adjust the position of the rendered images based on vehicle-to-vehicle distance.
Innovation Solution
A vehicle equipped with a light projection member and a detection device that adjusts the position of the road surface image rendered on the road surface to be closer to the vehicle than the rear end of the preceding vehicle, using a controller to select between normal and simplified light projection patterns based on detected vehicle-to-vehicle distance, thereby reducing the impact of reflected light on the preceding vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If road surface image rendering is performed with fixed position, then information can be provided to driver and others, but rearward visibility of preceding vehicle is impaired by reflected light
Solution Approach 1:
The patent applies dynamics by making the light projection position adjustable rather than fixed. The control unit dynamically changes the projection position on the road surface based on the detected distance to the preceding vehicle, allowing the system to adapt to different driving conditions and avoid impairing the preceding vehicle's rearward visibility while maintaining information transmission functionality
Solution Approach 2:
The patent changes the spatial parameter (projection position) of the light projection based on the detected distance to the preceding vehicle. By adjusting this parameter, the system resolves the contradiction between providing information and avoiding visibility impairment
2Object-affected harmful factors
If light projection position is adjusted to avoid preceding vehicle, then rearward visibility is improved, but information delivery effectiveness may be reduced
Solution Approach 1:
The patent applies local quality by selectively projecting light patterns in different positions based on the preceding vehicle's distance. When the vehicle is close, the projection is positioned away from the preceding vehicle to avoid visibility impairment. When the vehicle is far, the projection can be positioned optimally for information delivery, thus applying different projection qualities to different spatial locations

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution improves road surface image rendering by minimizing the impairment of rearward visibility for preceding vehicles through dynamic adjustment of the image position and intensity based on vehicle-to-vehicle distance, ensuring safer driving conditions.
Implementation Method 1
The light projection member is configured to perform light projection for road surface image rendering toward a road surface in front of the vehicle and render a road surface image on the road surface

AI summary
A vehicle with road surface image rendering functionality includes a light projection member, a controller, and a detection device. The light projection member is configured to perform light projection for road surface image rendering toward a road surface in front of the vehicle and render a road surface image on the road surface. The controller is configured to control the light projection for the road surface image rendering by the light projection member. The detection device is configured to detect a vehicle-to-vehicle distance to a preceding vehicle in front of the vehicle. The controller is configured to, in accordance with the vehicle-to-vehicle distance detected by the detection device, change a position of the road surface image rendered on the road surface by the light projection member and so that the position of the road surface image is closer to the vehicle than a rear end of the preceding vehicle.
