Vehicle Display Scale Control for Speed-Adaptive Surrounding Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display systems struggle to provide detailed information about the traveling environment when vehicle speed is low, leading to quick movement of the display and insufficient forward display distance at high speeds, causing driver irritation and inadequate situational awareness.
Innovation Solution
A vehicle display control device that adjusts the display scale based on vehicle speed, switching between telescopic and wide-angle views, and modifies the display mode to emphasize landmarks, ensuring clear and natural presentation of the surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display scale is set to telescopic to show detailed information, then the detail information about traveling environment is improved, but the display moves quickly and forward display distance becomes short at high speeds
Solution Approach 1:
The patent applies dynamics by making the display scale adjustable based on vehicle speed. The system dynamically switches between telescopic scale (for detailed information at low speeds) and wide-angle scale (for stable overview at high speeds), resolving the contradiction between showing detail information and preventing excessive display movement.
Solution Approach 2:
The patent changes the display scale parameter according to vehicle speed conditions. When vehicle speed is low, the display uses telescopic scale to show detailed information; when vehicle speed is high, it switches to wide-angle scale to reduce display movement and maintain forward display distance.
2Length of stationary object
If the display scale is set to wide angle to show forward distance, then the forward display distance is improved, but the detail information about traveling environment is reduced
Solution Approach 1:
The system dynamically adjusts the display scale based on real-time vehicle speed data. At high speeds, wide-angle scale is used to extend forward display distance; at low speeds, telescopic scale is applied to provide detailed information, thus resolving the contradiction between forward distance and detail information.
Solution Approach 2:
The display scale parameter is changed according to vehicle speed conditions. The system switches between wide-angle scale (for long forward display distance at high speeds) and telescopic scale (for detailed information at low speeds), optimizing both parameters under different operating conditions.
3Loss of information
If the display shows detailed surrounding information at low speed, then the situational awareness is improved, but the display becomes unstable and irritating at high speeds
Solution Approach 1:
The display scale parameter is adjusted based on vehicle speed to optimize situational awareness while minimizing driver irritation. At low speeds, telescopic scale provides detailed situational awareness; at high speeds, wide-angle scale reduces display instability and driver irritation.
Solution Approach 2:
The system dynamically adapts the display characteristics to vehicle speed conditions, providing detailed information when the vehicle is stationary or moving slowly, and switching to a more stable wide-angle view at high speeds to prevent driver irritation while maintaining essential situational awareness.
