Vehicle Software Update via V2V File Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for updating software in vehicle telematics units or navigation devices are cumbersome, requiring the use of external storage media and PC-access environments, leading to infrequent software updates due to inconvenience.
Innovation Solution
A method that allows for wireless software updates by determining if a vehicle terminal is outdated, selecting a neighboring vehicle with updated software, receiving a shared update file, and storing and applying it, thereby eliminating the need for external storage media and minimizing data costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software update is performed using PC and external storage media, then software can be updated, but the operation process becomes cumbersome and inconvenient
Solution Approach 1:
The vehicle terminal performs software updates autonomously by automatically detecting neighboring vehicles with updated software, initiating the update process, and completing the installation without requiring driver intervention or PC connection. The system serves itself by utilizing V2V communication to obtain and install update files automatically.
Solution Approach 2:
A neighboring vehicle with updated software acts as an intermediary, providing the update file to the vehicle terminal through wireless communication. This intermediary vehicle enables the update process without requiring external PC or storage media, facilitating direct peer-to-peer software distribution.
2Reliability
If software update is performed using PC connection and storage media, then software can be updated, but the process requires multiple steps and external devices
Solution Approach 1:
The patent extracts the update file transfer process from the traditional PC-based workflow by utilizing direct wireless communication between vehicles. This eliminates the need for external storage media and PC involvement, reducing the number of devices and steps required for the update process.
Solution Approach 2:
The patent combines the software update function with the existing V2V communication system, merging multiple functions (software distribution, wireless communication, and automatic installation) into a single integrated process. This reduces device complexity by eliminating separate update mechanisms.
3Reliability
If driver manually updates software using PC and storage media, then software can be updated, but driver time and effort are consumed
Solution Approach 1:
The system performs preliminary actions by automatically detecting the need for software updates, locating neighboring vehicles with updated software, and initiating the download and installation process before the driver would need to manually intervene. This automated preliminary action eliminates driver time consumption for the update process.
Solution Approach 2:
The vehicle terminal autonomously manages the entire update process including detection, communication, file reception, and installation without requiring driver time or effort. The system serves itself by utilizing V2V communication to obtain and install update files automatically.

AI summary
Disclosed is a method of updating software for a vehicle. The method includes determining whether a vehicle terminal of the vehicle is running out-of-date software; selecting a target vehicle among neighboring vehicles via wireless communication, wherein the target vehicle is running updated software; receiving a shared update file from the target vehicle via wireless communication, the shared update file based on the updated software; storing the shared update file; and updating the out-of-date software using the shared updated file.
