Vehicle Cluster Data Restoration via Diagnosis System Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When replacing a vehicle's cluster or electronic control unit (ECU), existing systems fail to restore stored driving information efficiently, leading to inconvenience and potential random operation of the information.
Innovation Solution
A driving information restoration system that uses an authorized diagnosis system to compare and synchronize data between the cluster and ECU, employing a receiving standby mode and hot key information to accurately restore driving information without operational errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cluster or ECU is replaced, then the vehicle can use a new or functioning component, but all stored driving information is lost
Solution Approach 1:
The patent implements a copying mechanism where driving information is extracted from the original cluster or ECU and transferred to the replacement component. The diagnosis system reads stored driving information (such as vehicle speed, RPM, fuel consumption data) from the original component and copies it to the new component, preserving all driving information without requiring manual re-entry or recalibration.
Solution Approach 2:
The system performs preliminary actions by automatically detecting when a cluster or ECU replacement has occurred through component identification signals. Upon detection, the system proactively initiates the information restoration process before the user can operate the vehicle, ensuring driving information is restored seamlessly without requiring user intervention or causing operational delays.
2Loss of information
If manual restoration methods are used, then some driving information can be recovered, but the process is time-consuming and prone to random operations
Solution Approach 1:
The patent implements a self-service mechanism where the diagnosis system automatically performs the entire information restoration process without requiring manual user input. The system autonomously detects the replacement condition, identifies the appropriate information to restore, executes the transfer process, and verifies successful restoration. This eliminates time-consuming manual operations and prevents random user actions that could cause errors.
Solution Approach 2:
The system incorporates feedback mechanisms to monitor the restoration process in real-time. The diagnosis system continuously checks whether the replacement component is ready to receive information, tracks the transfer progress, and verifies successful restoration by comparing data integrity. This automated feedback loop ensures accurate restoration while minimizing the time required, as the system only performs necessary operations based on actual system state.
3Productivity
If no verification system is in place, then restoration can be performed quickly, but random operation of driving information may occur
Solution Approach 1:
The patent implements a verification feedback system where the diagnosis system checks multiple conditions before and during the restoration process. It verifies that the replacement component is properly installed and ready to receive information, confirms the data being transferred is complete and valid, and checks that the restoration was successful. This automated verification ensures high reliability while maintaining fast restoration speeds, as the system only performs validated operations without requiring slow manual verification steps.

AI summary
A driving information restoration system of a vehicle includes: a cluster configured to be operated in a receiving standby mode or transmit driving information stored therein to a diagnosis system depending on a comparison result of the driving information stored therein and driving information stored in controller, display hot key information received from the diagnosis system, transmit information input by a driver to the diagnosis system, and store the driving information received from the diagnosis system.
