Vehicle Remote Cancellation Authorization via Portable Unit Record Matching

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing remote operation systems for vehicles allow unauthorized cancellation of local operations by remote operators, leading to unintended disruptions and potential legal violations, as the remote operator cannot determine the local operator's intention.

Innovation Solution

A system where local operation records are stored in both a vehicle and a portable unit, with authorization for cancellation given only when the records from both match, ensuring that only the local operator can cancel local operations through a remote operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If remote operation is allowed to cancel local operations without limitation, then remote operation convenience is improved, but unauthorized cancellation and unintended disruptions occur

Engineering Contradiction:

Improveremote operation convenienceVSAvoidauthorization accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary actions by storing operation records in advance in both the vehicle and portable unit before remote cancellation is requested. When a remote cancellation request is received, the system compares the stored records to verify authorization, ensuring that only the local operator can authorize cancellations while maintaining remote operation convenience.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If remote cancellation is permitted, then remote control capability is improved, but local operator intention cannot be determined leading to unintended disruptions

Engineering Contradiction:

Improveremote control capabilityVSAvoidlocal operator intention

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system implements feedback by storing operation records in both the vehicle and portable unit, then comparing these records when a remote cancellation is requested. This feedback mechanism verifies whether the remote operator is the local operator, thereby determining the local operator's intention and preventing unintended disruptions while maintaining remote control capability.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If remote operation can cancel local operations, then operational flexibility is improved, but legal violations may occur when hazard lights are involved

Engineering Contradiction:

Improveoperational flexibilityVSAvoidlegal violation risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary verification by storing and comparing operation records before allowing remote cancellation. This ensures that only the local operator can authorize cancellations, preventing unauthorized cancellation of hazard lights and avoiding legal violations while maintaining operational flexibility for other vehicle functions.

Inventive Principle:

Principle #10Preliminary action

AI summary

When a local operation is carried out on a vehicle, a local operation record is stored in a storage section of a remote operation control master unit and a storage section of a smart entry key. When a remote operation of canceling the local operation is carried out, the local operation record stored in the smart entry key is transmitted to the vehicle through a cellular phone. The local operation record received by an in-vehicle communication device is compared with the local operation record stored in the storage section of the remote operation control master. When the comparison result indicates the agreement between the local operation records, the authority for canceling the local operation is given.
