Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting systems lack the ability to dynamically adjust light patterns based on navigation information and driving assistance data, limiting their effectiveness in enhancing navigation accuracy and safety, particularly in autonomous driving scenarios.
Innovation Solution
A vehicle light control method that obtains driving information, such as navigation and driving assistance data, to determine a target light pattern that corresponds to the vehicle's path, allowing for dynamic adjustments in shape, size, and intensity to improve navigation and safety by projecting specific light patterns on the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing indicator lamps implement only single indication functions, then the device structure remains simple, but the navigation accuracy and driving safety are insufficient
Solution Approach 1:
The patent applies multi-functionality by enabling vehicle lights to perform both traditional indication functions and navigation path projection functions. The lighting system projects light patterns corresponding to navigation information and driving assistance data, allowing a single lighting component to serve multiple purposes: indicating vehicle status and displaying the intended driving path on the road surface.
Solution Approach 2:
The patent merges navigation information display and driving indication functions into a unified lighting system. By combining the projection of path information with traditional indicator lamp functions, the system integrates multiple information channels into a single visual output mechanism, improving safety without proportionally increasing system complexity.
2Measurement precision
If vehicle lights project detailed light patterns on the path, then navigation accuracy improves, but energy consumption increases
Solution Approach 1:
The patent applies local quality by projecting light patterns only in the specific regions where navigation information needs to be displayed, rather than illuminating the entire driving path uniformly. The system concentrates light energy on critical path segments and key turning points, providing sufficient navigation accuracy while minimizing overall energy consumption.
3Loss of information
If the light pattern dynamically adjusts to match driving information, then the information transmission effectiveness improves, but the control system complexity increases
Solution Approach 1:
The patent implements feedback control by continuously monitoring driving information from navigation systems and driving assistance systems, then dynamically adjusting the projected light patterns in real-time. The lighting system receives feedback signals about the vehicle's intended path and current state, automatically modifying the light projection to maintain accurate and up-to-date navigation information display.
