Vehicle Communication Tool Padding Retry for Reliable Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent padding values between external devices and vehicle electronic systems can lead to communication malfunctions, disrupting function updates and malfunction diagnoses, reducing user convenience.
Innovation Solution
A communication system with a communication tool and target units that manage padding values by matching preset values, adjusting padding values if inconsistencies are detected, and using a priority order to systematically find the correct padding value, thereby ensuring consistent communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If padding values are transmitted in communication data blocks, then data transmission is enabled, but communication malfunctions occur when padding values are inconsistent between external devices and vehicle electronic systems
Solution Approach 1:
The target unit provides feedback by transmitting abnormality information when a padding value mismatch is detected. The communication tool receives this feedback and automatically adjusts the padding value in subsequent transmissions, creating a closed-loop system that resolves inconsistencies without manual intervention.
Solution Approach 2:
The communication tool autonomously detects padding value inconsistencies through the abnormality information feedback and self-corrects by adjusting the padding value in retry transmissions. This self-service mechanism eliminates the need for external intervention to resolve communication malfunctions.
2Measurement precision
If communication malfunctions are detected due to padding value inconsistencies, then communication errors are identified, but function updates and malfunction diagnoses are disrupted
Solution Approach 1:
The system performs preliminary error detection by checking padding values before proceeding with function updates or malfunction diagnoses. When an inconsistency is detected, the communication tool adjusts the padding value in advance, preventing communication failures during critical operations and maintaining productivity.
Solution Approach 2:
The abnormality information feedback mechanism enables real-time detection of padding value errors, allowing the communication tool to correct issues before they disrupt function updates or diagnoses, thus maintaining operational efficiency.
3Reliability
If padding value discrepancies are not resolved, then communication interruptions occur, but user convenience is reduced
Solution Approach 1:
The communication tool automatically detects and resolves padding value discrepancies without requiring user intervention. This self-service capability maintains communication continuity and preserves user convenience by eliminating manual troubleshooting and reconfiguration needs.
Solution Approach 2:
The feedback loop involving abnormality information transmission enables automatic resolution of padding value issues, ensuring communication continuity while maintaining ease of operation by removing the burden of manual error correction from the user.

AI summary
A communication system includes a target unit provided in a vehicle and including at least one target unit processor and at least one target unit memory coupled to each other; and a communication tool coupled to the target unit for bidirectional communication and including at least one communication tool processor and at least one communication tool memory coupled to each other. The communication tool processor transmits certain information including first certain data and a first padding value to the target unit. The target unit processor determines whether the first padding value matches a preset specific padding value, and transmits abnormality information to the communication tool when the first padding value does not match the specific padding value. Upon receiving the abnormality information, the communication tool processor transmits the certain information including the first certain data and a second padding value different from the first padding value to the target unit.
