Vehicle Software Update Approval Using Multi-Granularity Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Software updates on vehicle control devices (ECUs) often require user approval, but existing methods do not effectively ensure user convenience, especially when updates occur outside the user's home, as they lack a systematic approach to presenting approval information across different devices.
Innovation Solution
A server system that sends distinct levels of data for user approval via wireless communication, with higher information granularity on user equipment compared to in-vehicle displays, allowing seamless continuation of approval processes across devices without re-viewing previously seen content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same approval data is displayed on both in-vehicle display and user equipment, then information consistency is maintained, but user convenience deteriorates when updates occur outside home requiring re-viewing of content
Solution Approach 1:
The patent segments approval information into two distinct data sets: first data for in-vehicle display and second data for user equipment. This segmentation allows each device to receive optimized information appropriate to its context, eliminating the need for users to re-view content when switching between devices during the approval process.
Solution Approach 2:
The patent applies local quality by providing different information granularities to different devices based on their specific use contexts. The second data for user equipment includes higher information granularity (more detailed character information and video content) compared to the first data for in-vehicle display, optimizing the user experience for each device's operational context.
2Loss of information
If higher information granularity is provided on user equipment, then user understanding is improved, but data transmission complexity increases
Solution Approach 1:
The server segments approval information into two distinct data sets with different granularities. The second data for user equipment contains higher information granularity including more character information and video content, while the first data for in-vehicle display contains condensed information. This segmentation enables optimized information delivery to each device type.
Solution Approach 2:
The patent implements local quality by tailoring the information granularity to match the specific device and context. User equipment receives comprehensive second data with video and detailed text for thorough understanding, while in-vehicle displays receive streamlined first data suitable for quick review during driving, optimizing information delivery for each location.
3Ease of operation
If approval information is displayed only in the in-vehicle display, then device simplicity is maintained, but user convenience deteriorates when outside home
Solution Approach 1:
The patent implements multi-functionality by enabling the software update approval system to operate effectively across multiple device types (in-vehicle display and user equipment). The server is configured to provide appropriate approval data to whichever device the user accesses, making the approval process universally accessible regardless of location or device availability.
Solution Approach 2:
The server acts as an intermediary that manages and distributes approval information to both in-vehicle displays and user equipment. It coordinates the approval process across devices, tracking which data has been viewed and ensuring seamless continuation of the approval flow whether the user starts on one device and continues on another.
Data Source
AI summary
A server configured to send data for updating software on a vehicle control device though wireless communication includes: one or more memories configured to store a program; and one or more processors. The one or more processors are configured to execute the program. The one or more processors are configured to set first data and second data. The first data is data to be displayed on an in-vehicle display in order to obtain user's approval to the software update. The second data is data to be displayed on user equipment in order to obtain the user's approval to the software update. The second data has higher information granularity than the first data.
