OTA Update Installation Control in Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems lack an efficient method for managing over-the-air (OTA) updates, particularly in ensuring timely and user-interactive installation of software and firmware updates while preventing unintended disruptions to vehicle operations.
Innovation Solution
A system that includes a communication module for downloading OTA update packages, a display control module for user input solicitation, an immobilization module for restricting vehicle functions during updates, and timer modules for automating the update process based on predetermined periods, allowing users to choose installation timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle is immobilized during OTA update installation to ensure safety and prevent disruptions, then update reliability is improved, but vehicle usability and user convenience deteriorate
Solution Approach 1:
The system performs preliminary actions by notifying the user in advance of the scheduled update time and obtaining user consent before the actual update installation begins. The notification is displayed at a predetermined time before the update starts, allowing users to prepare and ensure the vehicle is in a suitable state for updates.
Solution Approach 2:
The system dynamically adjusts the update installation process based on user input. Users can cancel or reschedule updates by providing input through the user interface before the update begins, making the system flexible and adaptive to changing user needs while maintaining safety through controlled immobilization.
2Productivity
If automatic update installation is implemented without user intervention to improve productivity, then update installation efficiency is improved, but user control and safety monitoring deteriorate
Solution Approach 1:
The system provides self-service functionality by automatically installing updates once user consent is obtained and the predetermined time has elapsed. The control module autonomously executes the update installation process without requiring continuous user intervention, improving efficiency while maintaining user control through initial consent and cancellation options.
Solution Approach 2:
The system incorporates feedback mechanisms by displaying notifications to users before updates begin and allowing users to provide input to cancel or reschedule updates. This feedback loop ensures users remain informed and in control of the update process while benefiting from automated installation execution.
3Ease of operation
If a predetermined period is set before update installation to allow user notification, then user awareness and control are improved, but update installation time is extended
Solution Approach 1:
The system uses periodic action by setting a predetermined time interval between notification and actual update installation. This allows the system to notify users in advance at regular intervals before the update begins, providing adequate warning while maintaining a structured and predictable update schedule.

AI summary
An updating system of a vehicle includes a communication module configured to wirelessly download an over the air (OTA) update package. The OTA update package includes: a predetermined period for beginning installation of the OTA update package; an indicator of a module and code to be updated; and replacement code. A display control module is configured to, when a transmission of the vehicle is in park and the predetermined period has not yet passed after the downloading of the OTA update package, display a message on a display within a passenger cabin of the vehicle. The message solicits user input regarding whether to: (i) begin installation of the OTA update package; or (ii) install the OTA update package at a later time.
