Solution Overview

Problem

Existing vehicle control systems lack efficient mechanisms for notifying users of function limitations during over-the-air (OTA) updates of Electronic Control Units (ECUs), which can lead to unexpected vehicle behavior and user dissatisfaction.

Innovation Solution

The proposed system includes an information processing apparatus that embeds identification information within update programs, generating user notifications about function limitations before updates are performed. This system ensures that users are explicitly informed of impending function limitations, reducing the risk of unexpected vehicle behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If OTA update of ECU is performed, then system functionality is improved, but user awareness of function limitations deteriorates

Engineering Contradiction:
Improvesystem functionalityVSAvoiduser awareness
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary actions by notifying users of upcoming function limitations before the ECU update is executed. The notification is displayed in advance, allowing users to be aware of the temporary loss of certain vehicle functions during the update process, thus preventing information loss while maintaining system reliability.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If manual notification to users is used, then user awareness is improved, but operation complexity deteriorates

Engineering Contradiction:
Improveuser awarenessVSAvoidoperation complexity
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system implements self-service by automatically generating and displaying notifications to users about function limitations during ECU updates. The notification system operates autonomously, extracting necessary information from update data and presenting it to users without requiring manual intervention from technicians or complex operational procedures, thus improving user awareness while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service
