Vehicle Software Update System via Wireless Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle computing and infotainment systems require customers to physically visit a dealer for software and firmware updates, leading to delays and potential neglect in keeping software up to date, which can affect vehicle performance.
Innovation Solution
A system that uses a processor to receive notifications of available updates, assemble lists of installed software versions, and transmit them to a remote server for downloading and installation, allowing for over-the-air updates without dealer intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical connection to dealer is required for updates, then update reliability and compatibility can be ensured, but customer convenience and update speed deteriorate
Solution Approach 1:
The vehicle computing system performs self-diagnosis and self-update by automatically detecting available updates, verifying compatibility with installed software versions, and installing updates without requiring physical connection to a dealer or external programming system. The system uses its own processor and communication module to autonomously manage the update process.
Solution Approach 2:
The patent replaces the mechanical/physical connection system (requiring physical connection to dealer equipment) with a wireless communication-based system. The processor communicates with remote servers via wireless network to receive update information and install updates remotely, eliminating the need for physical connection while maintaining update reliability through automated verification processes.
2Reliability
If physical connection to dealer is required, then update installation can be controlled and verified, but update time and productivity deteriorate
Solution Approach 1:
The system continuously monitors for available updates and can install them at convenient times without interrupting vehicle operation. The processor automatically detects updates, verifies compatibility, and installs them in the background, allowing update operations to continue without requiring dedicated time for physical connection and manual installation procedures.
Solution Approach 2:
The patent replaces the time-consuming physical connection process with rapid wireless communication. The processor can quickly communicate with remote servers, retrieve update information, and install updates much faster than manual dealer processes, while maintaining verification through automated compatibility checking against installed software versions.
3Measurement precision
If dealer visits are required for updates, then comprehensive system scanning can be performed, but time loss and inconvenience increase
Solution Approach 1:
The vehicle computing system performs self-diagnosis by automatically detecting its own software versions and comparing them against available updates. The processor autonomously manages the entire update process including version detection, compatibility verification, and installation, eliminating the need for dealer time investment while maintaining accurate system assessment.
Solution Approach 2:
The system performs preliminary actions by continuously monitoring for updates and pre-verifying compatibility with installed software versions before installation is needed. This allows the system to be ready for updates at any time without requiring advance dealer scheduling or physical connection setup, reducing overall time loss.

AI summary
A system includes a processor configured to, in response to a notification received from a remote network that an update to vehicle software is available, assemble a list of installed vehicle software versions. The processor is also configured to transmit the list of installed versions to a remote update server. The processor is further configured to receive a list of available updates compatible with the installed vehicle software versions in response to the transmission. Additionally, the processor is configured to download at least one of the available updates and install the downloaded updates.
