Solution Overview

Problem

Existing vehicle software update processes often fail without providing clear reasons for failure, leading to unnecessary re-attempts without resolving the underlying issues.

Innovation Solution

A vehicle information processing device and storage medium that receive, install, and activate update software for electronic control devices, and provide notifications on the specific stage of failure during the update process, facilitating the identification of the cause of failure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the update process is automated without detailed failure notifications, then the ease of operation is improved, but the loss of information about failure causes increases

Engineering Contradiction:
Improveease of operationVSAvoidloss of information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system implements feedback by notifying users of the specific stage where the update process failed (download, installation, or activation). This feedback mechanism provides crucial information about failure causes while maintaining automated operation, allowing users to understand what went wrong without manual intervention in the update process itself.

Inventive Principle:
Principle #23Feedback

2Loss of information

If detailed failure stage information is provided, then the loss of information is reduced, but the device complexity increases

Engineering Contradiction:
Improveloss of informationVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The update process is segmented into three distinct stages: download, installation, and activation. By dividing the overall update process into these separate segments, the system can identify and report failures at specific stages without requiring complex overall system redesign. Each stage can be monitored and reported independently.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If the update process monitors each stage individually, then the measurement precision of failure detection is improved, but the device complexity increases

Engineering Contradiction:
Improvemeasurement precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The monitoring system is segmented to track each update stage (download, installation, activation) separately. This segmentation enables precise identification of where failures occur without requiring a completely complex monitoring infrastructure, as each stage can be monitored with relatively simple checks.

Inventive Principle:
Principle #1Segmentation

AI summary

A vehicle information processing device includes a processor. The processor performs download by receiving update software for an electronic control device mounted on a vehicle. The processor performs installation by causing the electronic control device to store the downloaded update software. The processor performs activation by validating the installed update software. The processor makes a notification of which stage among the download, the installation, and the activation a trouble has occurred in when update to the update software is not successfully completed. The update to the update software is completed when all of the download, the installation, and the activation are completed.
