Vehicle Environment Visualization Head Position Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for visualizing a motor vehicle's environment rely on fixed reference points, such as the driver's sitting position, which are inadequate as they do not account for changes in head position or the varying field of vision, leading to suboptimal intuitive depiction of the surroundings.
Innovation Solution
A method utilizing cameras and display units that adapt to the detected head position of vehicle passengers, allowing the depiction of the environment as if the display unit were a transparent window, ensuring an intuitive and dynamic representation of the surroundings by using transformation matrices and internal sensors to align the display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display apparatus uses a fixed reference point (driver's sitting position) for environmental visualization, then the system structure is simple, but the visualization accuracy deteriorates when head position changes
Solution Approach 1:
The patent implements dynamic adaptation by detecting the driver's actual head position and dynamically adjusting the reference point for environmental visualization. Instead of using a fixed sitting position reference, the system continuously updates the reference based on detected head position, transforming the static visualization system into a dynamic one that adapts to changing viewing conditions.
Solution Approach 2:
The system employs feedback mechanisms by using detection apparatus (cameras or sensors) to monitor the driver's head position and feeding this information back to the control unit. The control unit then adjusts the visualization reference point accordingly, creating a closed-loop system that continuously optimizes visualization accuracy based on actual viewing conditions.
2Ease of operation
If the display apparatus adapts to head position changes, then the visualization intuitiveness is improved, but the device complexity increases
Solution Approach 1:
The system achieves self-service by automatically detecting head position and adjusting the visualization reference point without requiring manual intervention from the driver. The detection apparatus and control unit work autonomously to maintain optimal visualization, eliminating the need for manual calibration or adjustment by the user.
Solution Approach 2:
The detection apparatus serves multiple functions: it detects both the driver's head position and the environmental information. By combining these functions, the system reduces overall complexity while improving intuitiveness, as the same hardware infrastructure supports both detection tasks.
3Adaptability or versatility
If the reference point is fixed at the driver's sitting position, then the system is simple to implement, but it fails to account for varying fields of vision
Solution Approach 1:
The system transforms the static reference point into a dynamic one that adapts to varying fields of vision. By continuously detecting head position and adjusting the reference point accordingly, the system maintains adaptability to different viewing angles and distances without requiring multiple fixed reference points or complex manual configuration.
