Solution Overview

Problem

Current vehicle gateway systems require high-capacity recording media for software updates, leading to complex information management, especially due to frequent updates in vehicle control and multimedia systems.

Innovation Solution

A vehicle gateway device that determines whether incoming information is for vehicle control or multimedia systems, recording and managing vehicle system updates while transmitting multimedia updates to a separate processing unit, thereby reducing the amount of data stored and simplifying management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the in-vehicle gateway stores all update information for both vehicle control systems and information systems, then all information can be updated, but the recording medium requires high capacity and management becomes complicated

Engineering Contradiction:
Improveinformation update capabilityVSAvoidmemory capacity
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent segments information into two categories: vehicle control information (stored locally in the gateway) and information system information (transmitted to external servers). This segmentation allows the gateway to maintain only essential data, reducing memory capacity requirements while preserving comprehensive update capabilities through collaborative processing between the gateway and external servers.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the in-vehicle gateway stores all update information for both vehicle control systems and information systems, then all information can be updated, but information update management becomes complicated

Engineering Contradiction:
Improveinformation update capabilityVSAvoidinformation update management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts information system update management from the gateway's responsibilities and transfers it to external servers. The gateway retains only vehicle control information management, which is critical for safety. This extraction simplifies the gateway's management complexity while maintaining comprehensive update capabilities through the external server infrastructure.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the recording medium capacity is increased to handle all information updates, then all systems can be updated, but the gateway device becomes more complex and costly

Engineering Contradiction:
Improveinformation update capabilityVSAvoidgateway structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces external servers as intermediaries to handle information system update storage and management. The gateway acts as a mediator that routes different types of information to appropriate destinations: vehicle control information goes to local storage, while information system updates are forwarded to external servers. This intermediary approach reduces gateway complexity and cost while maintaining comprehensive update capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A vehicle gateway device is provided in a vehicle and can update information acquired by communication with outside the vehicle. The vehicle gateway device determines whether the update information acquired by communication with outside the vehicle is information for a vehicle system related to vehicle control, records and manages the update information when it is determined that the update information is information for the vehicle system, and transmits the update information to an information processing unit when it is determined that the update information is not information for the vehicle system. In this way, a recording medium with low memory capacity can be used to update information and information update management can be simplified.
