Vehicle Software Update Approval Sync via Direct Device Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face difficulties in synchronizing operation results for software update approval requests between vehicles and mobile devices, leading to inconsistent responses.
Innovation Solution
Implementing direct communication between vehicles and mobile devices to exchange operation results for software update approval requests without server intervention, allowing for synchronized responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the server transmits approval requests to both the vehicle and the mobile device, then the user can receive the approval request through multiple channels, but it becomes difficult to synchronize the operation results between the vehicle and the mobile device
Solution Approach 1:
The patent introduces a direct communication channel between the vehicle and mobile device as an intermediary mechanism. When the vehicle receives an operation result, it directly transmits this result to the mobile device without server intervention. This intermediary direct link ensures that both devices have consistent operation results, resolving the synchronization issue while maintaining the ability to deliver approval requests through multiple channels.
2Ease of operation
If the vehicle and mobile device independently process approval requests through the server, then each device can operate autonomously, but the response time increases due to multiple server round trips
Solution Approach 1:
The patent segments the communication process into two parts: approval request transmission (through the server to both devices) and operation result notification (directly from vehicle to mobile device). This segmentation allows each device to maintain autonomy in receiving and processing approval requests while eliminating redundant server round trips for result synchronization, thereby reducing overall response time.
3Extent of automation
If the vehicle notifies the mobile device of operation results through the server, then the server maintains centralized control, but the notification process becomes slower and less reliable
Solution Approach 1:
The patent establishes a preliminary direct communication pathway between the vehicle and mobile device for operation result notifications. This preliminary action creates a dedicated notification channel that bypasses the server for this specific function, enabling faster and more reliable notifications while the server retains centralized control over approval request distribution and overall system coordination.

AI summary
A vehicle equipped with an electronic control unit includes: one or more communication devices configured to receive from a server an approval request to a user regarding update of software used in the electronic control unit; and one or more processors configured to receive a predetermined vehicle-side operation for the approval request, perform control for notifying, to an information processing device of the user, a vehicle-side operation result of the predetermined vehicle-side operation without going through the server when the predetermined vehicle-side operation is received, and perform control for withdrawing the approval request received by the one or more communication devices when the vehicle receives from the information processing device a device-side operation result of a predetermined device-side operation. The predetermined device-side operation is an operation received in the information processing device and is an operation for the approval request transmitted from the server to the information processing device.
