Solution Overview

Problem

Existing vehicle control systems using mobile terminals lack secure identification mechanisms, allowing unauthorized users to potentially operate vehicles remotely, leading to risks of theft and unauthorized access.

Innovation Solution

A vehicle controller system that includes a communicator and a control unit to verify identification information specific to the vehicle, ensuring that only authorized users can control vehicle operations by matching stored and updated identification data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mobile phone and in-vehicle apparatus are associated for remote operation, then user can control vehicle operations remotely, but stranger can operate vehicle when their in-vehicle apparatus is insidiously installed

Engineering Contradiction:

Improveremote operation capabilityVSAvoidauthorization security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary association between the mobile terminal and in-vehicle apparatus before remote operation begins. The control permission is granted only after the mobile terminal is properly associated with the authorized in-vehicle apparatus, preventing unauthorized strangers from operating the vehicle remotely.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback by notifying the user when an unknown in-vehicle apparatus is detected or when association status changes. This feedback mechanism allows users to verify whether their mobile terminal is properly associated with the correct in-vehicle apparatus, enhancing security awareness and enabling timely intervention against unauthorized access.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If in-vehicle apparatus is insidiously installed in proper user's vehicle, then stranger gains control capability, but vehicle and items are in danger of being stolen

Engineering Contradiction:

Improvecontrol accessVSAvoidtheft risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system applies preliminary anti-action by detecting and notifying users of unknown in-vehicle apparatus before they can be used for unauthorized control. By alerting users to potential insidious installations, the system prevents strangers from exploiting these devices to steal vehicles or items.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The notification system acts as an intermediary between the mobile terminal and the user, providing an additional layer of security verification. Before control permission is granted, the system mediates by confirming the legitimacy of the in-vehicle apparatus through user notification and verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A vehicle controller installed in and controlling a vehicle includes an obtaining part that obtains identification information specific to the vehicle, a communicator that communicates with an information processor located outside the vehicle by transmitting and receiving information, a match judging part that makes a matching judgment on whether a plurality of the identification information obtained at different times are identical, and a judging part that judges whether to permit the control of the vehicle based on the matching judgment. The information processor also can make the matching judgment and only transmit a control command to the vehicle controller when there is a match.
