Vehicle Navigation Cues Using HUD and Ground Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle navigation systems provide limited flexibility and clarity in route guidance, making it difficult for drivers to accurately determine navigation directions, especially in varying environmental conditions.
Innovation Solution
A navigation method that utilizes multiple apparatuses, such as a head-up display (HUD) and vehicle lights, to display navigation identifiers both on the vehicle's windshield and ground, providing multi-dimensional navigation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If navigation information is displayed through a single apparatus, then the system complexity is low, but the navigation flexibility and clarity are limited
Solution Approach 1:
The patent combines multiple display apparatuses (HUD, vehicle lights, ground projection devices) to present navigation information simultaneously. This merging of multiple devices enables flexible adaptation to different driving scenarios and environmental conditions, resolving the contradiction by accepting increased system complexity in exchange for significantly improved navigation versatility and clarity
Solution Approach 2:
The navigation system is designed to work with multiple types of apparatuses that can serve different functions - HUD for windshield display, vehicle lights for peripheral illumination, and ground projection for route marking. This multi-functional approach allows the system to adapt to various navigation needs while maintaining a unified control architecture
2Loss of information
If navigation information is displayed in multiple dimensions and locations, then the navigation clarity and intuitiveness are improved, but the device complexity increases
Solution Approach 1:
The patent extends navigation display from traditional two-dimensional windshield HUD to three-dimensional space by projecting navigation identifiers onto the ground and using vehicle lights for spatial illumination. This dimensional expansion provides drivers with intuitive spatial awareness of navigation routes while maintaining coordinated control through a unified system
3Reliability
If multiple apparatuses are used to display navigation identifiers, then the navigation effect is improved, but the ease of operation decreases
Solution Approach 1:
The navigation system automatically selects and activates appropriate display apparatuses based on real-time driving conditions, environmental factors, and navigation requirements. This self-service capability allows the system to optimize navigation presentation without requiring manual intervention from the driver, maintaining operational simplicity while ensuring reliable navigation effects across diverse scenarios

AI summary
A navigation method, a navigation apparatus, a navigation system, a computer-readable storage medium, and a vehicle are provided. The navigation method includes: obtaining navigation information of a vehicle (S410); displaying a first navigation identifier in front of the vehicle through a first apparatus (S420); and displaying a second navigation identifier in front of the vehicle through a second apparatus (S430). The first navigation identifier and the second navigation identifier are used to jointly display the navigation information. According to the method, multi-dimensional navigation information can be provided for a driver, so that navigation flexibility and a navigation effect can be improved, and navigation experience can be improved.
