Solution Overview

Problem

Existing in-vehicle management technologies are limited in their ability to improve sleep control functions, particularly for devices that do not support specific messages within the in-vehicle network.

Innovation Solution

An in-vehicle management device equipped with a detection unit to identify target devices that do not support a predetermined message, and a control unit that initiates a sleep state for these devices when a predetermined message cessation is detected for a specified period.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing in-vehicle management technologies are used, then communication control is maintained, but sleep control functions cannot be improved for devices that do not support specific messages

Engineering Contradiction:

Improvesleep control functionVSAvoidmanagement system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The in-vehicle management device acts as an intermediary between standard-compliant devices and non-compliant devices. It translates and manages communication for devices that do not support the predetermined sleep control messages, enabling them to enter sleep states indirectly through the management device's control actions.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The management device provides universal sleep control functionality across all device types in the network. It handles both standard-compliant devices that can process sleep control messages directly and non-compliant devices that require indirect management, making the sleep control system universally applicable throughout the entire in-vehicle network.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Use of energy by moving object

If non-compliant devices remain in active state, then communication compatibility is maintained, but power consumption increases

Engineering Contradiction:

Improvepower consumptionVSAvoidmessage protocol compatibility

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The management device serves as a mediator that enables power-saving for non-compliant devices without requiring them to understand or support the standard sleep control messages. It translates management actions into appropriate control signals for these devices, achieving energy savings while maintaining protocol compatibility.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces the need for non-compliant devices to have native support for complex sleep control message protocols with a simpler management-based control mechanism. The management device handles the protocol complexity centrally, allowing individual devices to use simpler communication methods while still achieving sleep control functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The in-vehicle management device includes: a detection unit configured to detect the presence of a target device that is an in-vehicle device that does not support a predetermined message among in-vehicle devices included in an in-vehicle network; and a control unit configured to perform control for causing the target device detected by the detection unit to transition to a sleep state when a state where the predetermined message from the in-vehicle devices does not arrive at the in-vehicle management device has continued for a predetermined period.
