Vehicle OTA Update Progress Control for Lower Communication Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During software updates in vehicles using over-the-air technology, unnecessary communication and increased power consumption occur when both the vehicle's display device and the user's terminal display progress notifications simultaneously.
Innovation Solution
The vehicle's control device transmits information on the progress of the software update process selectively to the user's terminal only upon request, reducing unnecessary communication and power consumption by distinguishing between first progress (e.g., update completion) and second progress (e.g., installation progress) and transmitting only when requested.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If progress notification is transmitted to both the vehicle's display device and the user's terminal simultaneously, then the user is kept informed about the software update progress, but unnecessary communication and power consumption occur
Solution Approach 1:
The patent applies local quality by differentiating the notification behavior between two different devices (vehicle display and user terminal). The vehicle's display device receives and displays all progress notifications locally, while the user terminal receives notifications selectively based on user presence detection. This localized differentiation resolves the contradiction by maintaining complete information availability in the vehicle while reducing unnecessary notifications to the user terminal when the user is absent.
2Loss of information
If progress notification is transmitted to both the vehicle's display device and the user's terminal simultaneously, then the user is kept informed about the software update progress, but unnecessary communication occurs
Solution Approach 1:
The patent implements local quality by making the notification transmission to the user terminal conditional on user presence detection. When the user is detected as present, full progress notifications are transmitted to both the vehicle display and user terminal. When the user is absent, notifications are transmitted only to the vehicle display, eliminating redundant communication data to the user terminal while preserving information availability through the vehicle display.
3Loss of information
If the user terminal receives progress updates continuously, then the user has real-time awareness of the update process, but power consumption and communication overhead increase
Solution Approach 1:
The patent applies dynamics by making the notification transmission to the user terminal dynamic and adaptive based on real-time user presence detection. The system continuously monitors whether the user is present and adjusts the notification behavior accordingly - enabling full notifications when the user is present and disabling them when absent. This dynamic adaptation optimizes communication efficiency while maintaining information availability when needed.

AI summary
A vehicle includes a communication device configured to execute communication between the vehicle and a communication instrument different from an instrument mounted on the vehicle, and a control device configured to control the vehicle. The control device is configured to acquire a plurality of types of progress in a process of updating software of the control device. The control device is configured to transmit information on first progress among the plurality of types of progress to the communication instrument by using the communication device. The control device is configured to transmit information on second progress different from the first progress among the plurality of types of progress to the communication instrument by using the communication device in response to a transmission request from the communication instrument.
