Vehicle Cluster USB Update Path Switching Without Panel Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for updating vehicle cluster software are cumbersome and require disassembly of the cluster panel, making it difficult for ordinary users to perform updates, leading to delayed software upgrades and missed opportunities for improved functions.
Innovation Solution
A USB-based software update apparatus and method that uses a USB terminal with a HUB IC for data transmission path switching, allowing the head unit to connect with the cluster via CAN communication to transmit and update cluster software without disassembly, enabling remote and easy updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cluster panel is disassembled and the storage device is updated using a separate update apparatus, then the software update can be performed, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent merges the update apparatus functionality directly into the cluster device by integrating a USB terminal and control unit within the cluster panel itself. This allows the cluster to perform self-updating without requiring external update apparatus or panel disassembly, resolving the contradiction between reliable software updates and ease of operation.
Solution Approach 2:
The cluster device is designed to perform software updates autonomously by itself. The control unit detects update files from the USB terminal and executes the update process automatically, eliminating the need for external update apparatus and complex manual operations while maintaining reliable update capability.
2Reliability
If the storage device is updated frequently at the car center, then the software can be kept up-to-date, but time and expenses are unnecessarily consumed
Solution Approach 1:
The cluster device performs self-updating by detecting and installing update files from a USB terminal without requiring trips to the car center. This autonomous update capability keeps software current while eliminating unnecessary time consumption and expenses associated with frequent professional updates.
Solution Approach 2:
The system allows update files to be prepared in advance on a USB terminal and then automatically installed by the cluster's control unit. This preliminary preparation of update files enables convenient, on-demand updates without requiring scheduled visits to service centers.
3Reliability
If the cluster panel is disassembled for storage device update, then the software can be updated, but the operation becomes difficult for ordinary people
Solution Approach 1:
The update functionality is merged into the cluster panel through integrated USB terminal and control unit. This eliminates the need for panel disassembly and external update apparatus, making the update process accessible to ordinary users through simple USB file operations.
Solution Approach 2:
The cluster automatically detects and executes updates from USB files without requiring user disassembly or complex manual intervention. This self-service capability makes software updates accessible to ordinary people who lack technical expertise in panel disassembly and storage device manipulation.
Data Source
AI summary
An apparatus and a method of updating cluster software use a universal serial bus (USB) terminal. The method includes connecting a USB memory to a USB socket of the USB terminal, determining whether a cluster software update file is present in the USB memory, by a head unit, when there is the cluster software update file, changing a USB host to a cluster, and receiving data for update from the USB memory and updating the software of the cluster, by the cluster.
