Vehicle Display Radar Map Overlay for Weather Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle navigation systems struggle to provide integrated and simultaneous displays of navigation information and weather data, requiring users to switch between different programs and devices, which can be unsafe and inconvenient, especially in bad weather.
Innovation Solution
A method for controlling a vehicle display screen that overlays weather information onto navigation map data, allowing both to be visible simultaneously, with adjustable scale and transparency to match the map data, and providing time-sensitive weather forecasts relevant to the vehicle's path of travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If weather information is displayed on a separate device or program, then weather data visibility is improved, but device complexity and ease of operation deteriorate due to requiring multiple devices and program switching
Solution Approach 1:
The patent combines weather information display with navigation map display on the same screen by overlaying weather data (radar images, forecasts, alerts) onto the map interface. This integration eliminates the need for separate devices or programs, allowing drivers to access both navigation and weather information simultaneously through a single unified display system.
Solution Approach 2:
The navigation display system is enhanced to perform multiple functions: it simultaneously provides navigation guidance, displays current weather conditions, shows weather forecasts, presents severe weather alerts, and maintains radar imagery - all within a single interface. This multi-functionality replaces the need for separate dedicated weather display devices.
2Loss of information
If weather information is displayed on a separate device, then weather data completeness is improved, but ease of operation worsens due to requiring program switching and separate device operation
Solution Approach 1:
The patent merges weather information completeness with navigation display by integrating multiple weather data types (radar, forecasts, alerts) directly onto the navigation screen. This allows users to obtain complete weather information without switching programs or devices, maintaining operational convenience while ensuring information completeness.
3Loss of information
If both weather information and map data are displayed simultaneously, then information integration is improved, but display clarity may deteriorate due to potential overlay conflicts
Solution Approach 1:
The patent applies local quality by making the weather information overlay semi-transparent rather than完全不透明. This allows the underlying map data to remain visible through the weather information layer, ensuring that both weather data and map features can be perceived simultaneously without one completely obscuring the other, thus maintaining display clarity while achieving information integration.
Data Source
AI summary
A method of controlling a display screen in a vehicle, includes obtaining and displaying map data and weather information on a display screen. The map data obtained from a navigation source and may include a path of travel and at least part of a geographic region adjacent to the path of travel. The weather information may be obtained from a weather source, may be displayed as a function of the geographic region. The display of weather information may be adjusted as a function of the part of the map data on the display screen so that the weather information is overlayed on the map data and both the weather information and the map data are visible simultaneously.
