Vehicle Light Pattern Projection With Priority-Based Road Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle light systems project multiple types of information onto the road surface, making it difficult for drivers and pedestrians to obtain relevant information in real time and intuitively due to cluttered and complex projections.
Innovation Solution
A method for vehicle lights that prioritizes and projects patterns based on their importance, using vehicle state and environment information to determine which patterns to project, and a vehicle light system that includes a controller to manage these patterns.

Engineering Contradiction Analysis
1Quantity of substance
If multiple types of information are projected onto the road surface, then the quantity of information provided to drivers and pedestrians increases, but the clarity and intuitiveness of the projected information decreases due to cluttered projections
Solution Approach 1:
The patent segments the projection area into multiple distinct regions (first projection area, second projection area, third projection area) and assigns different types of information to different regions. This spatial segmentation allows multiple information types to coexist without cluttering each other, maintaining both quantity and clarity simultaneously
Solution Approach 2:
Different regions of the projection area are assigned different functional qualities - the first projection area displays vehicle state information, the second displays surrounding environment information, and the third displays priority-based information. This local differentiation ensures each region serves its specific purpose clearly while contributing to the overall information richness
2Quantity of substance
If multiple patterns are projected simultaneously without priority management, then the completeness of information display increases, but the real-time responsiveness to critical information decreases
Solution Approach 1:
The control unit continuously monitors the states of multiple patterns and dynamically adjusts projection based on real-time conditions. When a high-priority pattern condition is met, the system immediately responds by projecting that pattern with higher brightness or in a prominent position, ensuring real-time responsiveness while maintaining complete information display through lower-priority patterns
Solution Approach 2:
The projection system dynamically adjusts the display characteristics of different patterns based on their priority levels and current conditions. The brightness, position, and visibility of projected patterns are not static but change dynamically according to the urgency and importance of the information being conveyed

AI summary
The present invention relates to a method for using a vehicle light to project a pattern. The method comprises: receiving information about a pattern to be projected, in which the information about the pattern comprises a pattern to be projected and a projection priority; determining a projection position of the pattern according to the information about the pattern; and projecting the pattern at the projection position, wherein when multiple patterns to be protected exist, a pattern having the highest priority is protected. In embodiments of the present invention, projection information is effectively classified according to respective priorities, and the positions of various projection information in a projection region are planned, thereby ensuring that information having a highest priority is presented to a driver of a vehicle, drivers of other vehicles and pedestrians in a timely manner. A vehicle status and surrounding environment information are easily and clearly acquired, thereby greatly improving driving safety. The present invention further relates to a vehicle system and a vehicle.
