AVDS User Terminal Data Prioritization for Critical Driving Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for automated valet driving lack an efficient method to prioritize and manage data transmission and processing between an Automated Valet Driving System (AVDS) and a user terminal, leading to potential delays and inefficiencies in responding to critical driving situations.
Innovation Solution
An apparatus and method for transmitting, receiving, and processing automated driving-related information between an AVDS and a user terminal based on priority settings, ensuring high-priority information is preferentially transmitted and processed to effectively handle emergency or critical situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission between AVDS and user terminal is performed without priority classification, then all data types can be transmitted, but response time to critical driving situations is delayed
Solution Approach 1:
The patent segments automated driving data into multiple priority levels (first priority for safety-critical data like MRM execution, second priority for operational data like MRC arrival, third priority for configuration data). This segmentation enables the system to process and transmit critical data immediately while managing less urgent data subsequently, thereby improving response speed to critical situations without overwhelming the data management system.
Solution Approach 2:
The patent introduces a priority parameter classification system that assigns different priority levels to different types of automated driving data. By changing the parameter of data identification from uniform to prioritized, the system can dynamically adjust transmission and processing order, ensuring critical data receives immediate attention while maintaining organized data management through structured priority handling.
2Reliability
If all automated driving data is processed equally, then comprehensive data handling is achieved, but critical safety information may be delayed
Solution Approach 1:
The patent establishes preliminary priority classification for different data types before transmission and processing occurs. By pre-defining which data types (such as MRM execution notifications) receive highest priority, the system is prepared in advance to immediately process safety-critical information when it arrives, ensuring reliable safety responses without time loss. This preliminary structuring prevents critical data from being delayed by less important processing tasks.
3Productivity
If priority-based data transmission is implemented, then critical information is transmitted promptly, but data management system becomes more complex
Solution Approach 1:
The patent implements a parameter-based priority classification system where data is tagged with priority levels (first, second, third priority) based on its type and importance. This parameter change enables efficient data transmission by allowing the system to quickly identify and process high-priority data without complex real-time analysis. The structured priority parameters simplify management compared to unclassified data handling, as they provide clear transmission rules for each data type.

AI summary
An apparatus to transmit and/or receive and process automated driving related information includes a transceiver and a processor to transmit and/or receive the automated driving related information with a user terminal through the transceiver and process the automated driving related information. The processor obtains information on a priority of the automated driving related information to be transmitted to the user terminal and, in a case in which the processor transmits a plurality of different types of automated driving related information, the processor transmits the plurality of the different types of the automated driving related information to the user terminal according to the obtained information on the priority.
