Vehicle Lane Data Broadcast via Dedicated Safety Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle communication systems relying on GPS data for safety applications, such as Intersection Movement Assist and Forward Collision Warning, face challenges due to low accuracy, which can lead to incorrect determination of lane and road information, potentially causing unnecessary alarms or failures in safety alerts.
Innovation Solution
A method for broadcasting dedicated vehicular safety information, including lane, road, and layer information, using a dedicated channel allocated according to regional standards, where electronic devices on vehicles obtain and broadcast this information using a combination of GPS, cameras for image processing, and sensors, ensuring accurate data transmission through standardized messages in specific frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS data is used for vehicle communication, then the system complexity is reduced and ease of operation is improved, but the measurement precision of lane and road information deteriorates
Solution Approach 1:
The patent segments the positioning system into multiple independent components: GPS module for coarse positioning, camera module for visual lane detection, and sensor modules for vehicle state monitoring. Each component operates independently and contributes specific data to the overall lane determination, thereby improving measurement precision without excessively increasing system complexity through modular architecture
Solution Approach 2:
The patent introduces an intermediary processing system that fuses data from GPS, cameras, and sensors. This intermediary layer processes and integrates information from multiple sources to determine accurate lane and road information, resolving the contradiction by adding intelligence rather than raw hardware complexity
2Reliability
If GPS data with low accuracy is used for safety applications, then the ease of operation is improved, but the reliability of safety alerts deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors lane position using multiple sensors and adjusts its determination based on discrepancies between GPS data and camera/sensor data. This feedback loop ensures high reliability of safety alerts by validating information through multiple independent verification channels
Solution Approach 2:
The system performs preliminary actions by pre-processing and validating data from multiple sources before making safety determinations. Lane information is pre-verified through camera recognition and sensor correlation before being used for safety applications, ensuring reliability while maintaining operational simplicity through automated preprocessing
3Loss of information
If only GPS broadcasting is used for vehicle communication, then the device complexity is reduced, but the loss of information increases due to insufficient lane and road detail
Solution Approach 1:
The patent merges multiple information sources (GPS coordinates, camera-derived lane markings, sensor data) into a unified communication message structure. By combining these diverse data types into standardized safety messages, the system reduces information loss about lane and road conditions without proportionally increasing communication system complexity through standardization
