Vehicle Shadow Area Guidance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers entering communications shadow areas face challenges in identifying the range of the shadow area and determining when their vehicle will regain signal reception, which can hinder response in emergency situations due to the lack of clear remaining distance information.
Innovation Solution
An apparatus and method that utilize a position identifier, shadow area information analyzer, distance calculator, and display controller to provide remaining distance information within predetermined sections of a communications shadow area by analyzing road information, identifying interpolation points, and calculating distances to the shadow area's termination point, outputting this information through a display or notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the vehicle enters a communications shadow area, then the signal receiving state is disabled, but the driver cannot identify the range of the shadow area or when signal reception will resume
Solution Approach 1:
The shadow area information is segmented into discrete distance intervals (e.g., 0-1km, 1-2km, 2-3km). The display controller divides the remaining distance into multiple sections and provides guidance for each section separately, making the continuous shadow area information manageable and comprehensible for the driver.
Solution Approach 2:
The system calculates and displays the remaining distance to the shadow area termination point in advance, before the vehicle actually exits the shadow area. This allows the driver to know ahead of time when signal reception will resume, enabling better planning and response to emergency situations.
2Ease of operation
If the system displays signal receiving state only, then the system complexity is low, but the driver cannot recognize the shadow area range or exit timing
Solution Approach 1:
The display controller serves multiple functions: it displays the current signal receiving state, shows the remaining distance to shadow area termination, divides the distance into manageable sections, and provides sequential guidance updates. This multi-functionality is achieved within the existing vehicle display system without adding separate dedicated components.
Solution Approach 2:
The shadow area information analyzer acts as an intermediary component that processes raw shadow area data and converts it into meaningful distance information. It calculates the remaining distance, divides it into sections, and prepares the data for display, serving as a bridge between the shadow area detection system and the user interface.
3Measurement precision
If the system provides continuous distance updates, then the information accuracy is high, but the information processing load increases
Solution Approach 1:
The system updates the distance information periodically based on predefined section intervals rather than continuously. The display controller provides guidance updates at specific distance milestones (e.g., when entering each 1km section), reducing the frequency of updates while maintaining useful precision for driver decision-making.
Data Source
AI summary
An apparatus and method for guiding a shadow area is provided. The method includes identifying a vehicle position on a driving path based on map information and global positioning system (GPS) information from a navigation system and analyzing road information in the shadow area by receiving position information for the shadow area on the driving path from a database in which information of the shadow area is stored. A remaining distance of the shadow area is calculated based on the vehicle position in the shadow area on the driving path and the remaining distance information of the shadow area is output.
