Navigation System Predicting Travel Direction for Focused Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems overwhelm drivers with excessive information, distracting them from the road and reducing safety by not effectively presenting relevant driving auxiliary information in a user-friendly manner.
Innovation Solution
A navigation system with a display interface that predicts the vehicle's traveling direction based on vehicle and road information, highlighting relevant road information such as traffic signs and signals through size, color, or contrast adjustments, and providing a pop-up window with suggested vehicle speed ranges and warnings, to assist drivers without diverting attention from the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple road information are provided to drivers in the same display way, then drivers can obtain comprehensive navigation information, but drivers are distracted from driving to look for information they needed
Solution Approach 1:
The patent applies local quality by differentiating the display treatment of different road information elements. Instead of uniform display, the system highlights specific road information (such as traffic signs and signals) that are relevant to the vehicle's current traveling direction with enhanced visual properties (color, size, contrast), while other information is displayed in a standard manner. This selective enhancement ensures drivers obtain comprehensive navigation information while minimizing distraction by making only the most relevant information stand out.
2Reliability
If real-time road condition and current route planning are shown to drivers, then drivers can make informed driving decisions, but the display complexity increases and may overwhelm drivers
Solution Approach 1:
The patent applies the extraction principle by selectively presenting only the most relevant road information elements to drivers at any given moment. The system extracts and highlights specific information such as traffic signs, signals, and road conditions that are directly related to the vehicle's current traveling direction, while omitting or de-emphasizing less relevant information. This extraction approach maintains reliability for driving decisions by ensuring critical information is available, while reducing display complexity by avoiding information overload.
3Measurement precision
If comprehensive road information is displayed, then navigation accuracy is improved, but the cognitive load on drivers increases
Solution Approach 1:
The patent applies local quality by enhancing the visual properties of specific road information elements that are most relevant to the vehicle's current traveling direction. By applying different visual weights (highlighting through color, size, or contrast adjustments) to different information elements, the system maintains high navigation accuracy by ensuring critical information is prominently displayed, while reducing cognitive load by making the information hierarchy clear and easy to process at a glance.
Data Source
AI summary
A navigation system for a motor vehicle is provided. A display interface is located in a vehicle. A is processor in communication with a vehicle sensor and a server. The processor is configured to receive vehicle information and road information, predict a traveling direction of the vehicle based on the vehicle information, and highlight the road information associated with the traveling direction on the display interface. A corresponding vehicle and method is also provided. A user of a navigation map can obtain auxiliary information to drive on the current route from a navigation interface more conveniently during the process of using the navigation map, thus providing the user an improved driving experience.
