Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
V2X technology applied to portable electronic devices often experiences inaccurate location estimation, leading to false or unnecessary safety warnings due to unreliable location information.
Innovation Solution
An electronic device and method are provided to enhance the reliability of V2X messages by incorporating a processor that determines the accuracy of location information and adjusts the display and output of traffic guide events based on this accuracy, using V2X communication modules to correct and verify location data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle executes all received V2X messages, then communication reliability is improved, but processing time increases and real-time responsiveness deteriorates
Solution Approach 1:
The patent segments V2X messages into different types (e.g., safety-related, information-related) and applies different processing strategies to each type. Safety-related messages are executed immediately while information-related messages are processed asynchronously, allowing the system to maintain reliability for critical messages while reducing overall processing time through selective execution.
Solution Approach 2:
The patent implements dynamic message processing where the vehicle adjusts its processing behavior based on current driving conditions and message urgency. The system can prioritize certain message types during high-risk situations while deferring less critical messages, enabling flexible time management that maintains reliability when needed without excessive processing delays.
2Loss of information
If the vehicle processes all received V2X messages, then message completeness is improved, but computational resource consumption increases
Solution Approach 1:
The patent extracts and separates critical message content from less critical message data. By identifying and processing only the essential information from V2X messages (such as safety-critical parameters) while deferring or skipping less important data processing, the system maintains message completeness for critical functions while significantly reducing computational resource consumption.
Solution Approach 2:
The patent applies different processing quality levels to different message components. Critical message parameters receive full processing and execution, while non-critical parameters receive reduced processing or are handled asynchronously. This local quality differentiation ensures that computational resources are allocated efficiently based on the importance of individual message elements.
3Productivity
If the vehicle delays execution of V2X messages, then real-time responsiveness is improved, but message timeliness deteriorates
Solution Approach 1:
The patent segments message execution into immediate and deferred processing streams. Critical safety-related messages are executed immediately to maintain timeliness, while information-related messages are processed in batches or asynchronously to preserve real-time responsiveness for critical functions without compromising the timeliness of essential safety information.

AI summary
An electronic device and method are disclosed. The electronic device includes a display device, a wireless communication circuit supporting vehicle-to-everything (V2X) communication, and at least one processor operatively connected to the display device and the wireless communication circuit. The processor may implement the method, including receiving a first V2X message from an external electronic device through the wireless communication circuit, determining, based on a location of the external electronic device included in the received first V2X message, and a present location of the electronic device, whether a traffic guide event has occurred, in response to determining that the traffic guide event has occurred, estimating a reliability of the traffic guide event, based on at least one of an accuracy of the location of the external electronic device, and an accuracy of the present location of the electronic device, and controlling the display device to display a guidance message based on the traffic guide event including an indication of the estimated reliability of the traffic guide event.
