VIN-Based Control Unit Configuration Update for Vehicle Fault Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control units face issues with permanent information maintenance, leading to incorrect error detection and unnecessary fault codes due to lack of updates, especially during vehicle assembly or service changes, necessitating a method to update control unit information via a remote server based on vehicle identification number (VIN) information.
Innovation Solution
A vehicle control apparatus and method that includes a processor configured to receive and compare vehicle identification information, establish a communication link with an external server to update configuration information for control units, and monitor their states, determining abnormal states and output fault codes as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If control unit information is permanently maintained without updates, then information stability is preserved, but incorrect error detection and unnecessary fault codes occur when vehicle assembly or service changes
Solution Approach 1:
The control unit information is transformed from a static permanent state to a dynamic state that can be updated. The system periodically checks for updates from an external server and refreshes configuration information when changes are detected, allowing the information to adapt to vehicle assembly or service changes while maintaining stability during normal operation
Solution Approach 2:
The system establishes a feedback mechanism where the control unit continuously monitors for configuration information updates from an external server based on VIN matching. When updates are available, the system retrieves and applies new configuration information, ensuring error detection accuracy is maintained while preserving information stability when no changes occur
2Reliability
If control unit information is updated via external server linkage, then error detection accuracy is improved, but system complexity and communication requirements increase
Solution Approach 1:
The control unit is designed with multi-functionality, serving both as the original control device and as a client capable of communicating with external servers. By integrating server communication capabilities directly into the control unit, the system avoids adding separate dedicated update devices, thereby improving error detection accuracy while minimizing the increase in overall system complexity
Solution Approach 2:
The control unit performs self-updates by autonomously communicating with the external server to retrieve and apply configuration information updates. This self-service capability eliminates the need for manual intervention or complex external update mechanisms, improving error detection accuracy while keeping the system relatively simple
Data Source
AI summary
A vehicle control apparatus includes a memory and a processor. The processor receives first identification information of a vehicle from a vehicle identification number (VIN) management control unit for managing identification information of the vehicle, compares second identification information of the vehicle with the first identification information, based on that the second identification information is identified in the memory, transmits the first identification information to an external server to request configuration information of a plurality of control units associated with the vehicle, based on that the first identification information and the second identification information are different from each other, and monitors the plurality of control units, based on receiving the configuration information from the external server.
