Autonomous Driving Message Relay for Non-V2X Object Hazards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving technologies face challenges in effectively communicating with and responding to objects in the driving environment that lack V2X communication capabilities, such as pedestrians or vehicles without advanced communication systems, which can lead to unsafe driving scenarios due to inadequate information exchange.
Innovation Solution
An electronic device equipped with sensors and a processor that obtains object data, determines the object's situation, and transmits appropriate messages through various communication channels based on the danger level, generating emergency messages for hazardous situations and default messages for non-hazardous ones, ensuring safe autonomous driving by informing vehicles capable of V2X communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous driving systems rely on V2X communication for information exchange, then communication efficiency is improved, but objects incapable of V2X communication (pedestrians, vehicles without advanced systems) cannot be effectively detected and responded to
Solution Approach 1:
The electronic device acts as an intermediary between V2X-capable vehicles and non-V2X objects. It receives object data from sensors or external servers, determines danger levels, and transmits standardized messages to vehicles. This mediator approach enables vehicles to communicate with pedestrians and non-V2X objects indirectly, resolving the contradiction between relying on V2X communication and needing to adapt to non-V2X objects.
2Loss of information
If the system transmits detailed object data and situation information continuously, then information completeness is improved, but communication bandwidth and processing load increase
Solution Approach 1:
The system applies local quality by transmitting different types of information based on danger level. For non-dangerous situations, only essential object data is transmitted. For dangerous situations, comprehensive object situation information is transmitted. This selective information transmission based on local conditions (danger level) reduces overall data quantity while maintaining information completeness when needed.
Solution Approach 2:
The system uses partial action by transmitting only the necessary portion of information based on the situation. Instead of continuously transmitting all available object data, it transmits partial information (basic object data) when safe, and excessive information (detailed situation analysis) only when dangerous, optimizing the balance between information completeness and data quantity.

AI summary
An electronic device and a method for assisting autonomous driving of a vehicle are provided. The electronic device includes: a communicator; a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory to: obtain object data of an object located in a driving environment of the vehicle; based on determining that the object incapable of communicating with the vehicle, obtain an object situation of the object, the object situation being determined based on the object data; determine whether the object situation is a dangerous situation; based on determining the object situation, determine a message type for notifying at least one of the object data and the object situation to the vehicle; and transmit a message generated according to the determined message type through the communicator.
