Solution Overview

Problem

Existing motor vehicle locking systems remotely controlled by a central server device face issues with ensuring the vehicle remains locked if communication connections are interrupted, leading to potential theft risks when users cannot manually lock the vehicle.

Innovation Solution

The method links remote-controlled unlocking to a condition where the motor vehicle's central server device monitors the communication connection, adding a conditional locking instruction that automatically locks the vehicle after a predetermined duration if the connection is lost, ensuring the vehicle remains secured even if the connection is interrupted.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If remote-controlled unlocking is implemented via central server device, then user convenience is improved, but theft protection deteriorates when communication connection is lost

Engineering Contradiction:
Improveremote-controlled unlockingVSAvoidtheft protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary actions by establishing communication connection monitoring and setting conditional locking instructions before the unlocking operation is completed. The central server device monitors the communication connection status and prepares conditional locking instructions that will be executed if the connection is lost during or after unlocking, thus preventing theft risk before it can occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring the communication connection status between the central server device and the motor vehicle. The monitoring result feeds back to determine whether to execute the conditional locking instruction, ensuring that the locking state is adjusted based on real-time connection status to maintain theft protection.

Inventive Principle:
Principle #23Feedback

2Reliability

If conditional locking instruction is added to monitor communication connection, then theft protection is improved, but device complexity increases

Engineering Contradiction:
Improvetheft protectionVSAvoidlocking system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The central server device performs multiple functions: it not only sends unlocking instructions but also monitors communication connection status and determines conditional locking execution. The control device similarly handles both unlocking and conditional locking operations. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while maintaining improved theft protection.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If communication connection monitoring is implemented, then theft protection is improved, but use of energy increases

Engineering Contradiction:
Improvetheft protectionVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic action by monitoring the communication connection status at specific intervals or at critical moments (before unlocking, during unlocking, and after unlocking) rather than continuously. The conditional locking instruction is evaluated periodically based on connection status changes, reducing energy consumption compared to continuous monitoring while maintaining adequate theft protection.

Inventive Principle:
Principle #19Periodic action

AI summary

A method for operating a motor vehicle locking system for a motor vehicle. A central server device receives an unlocking signal having an unlocking instruction about unlocking of at least one closing device of the motor vehicle. The central server device adds a conditional locking instruction to the unlocking signal, which includes after at least one predetermined duration T after unlocking of the at least one closing device of the motor vehicle, checking for a connection criterion and, in the case of an infringed connection criterion, locking the at least one closing device again. The unlocking signal having the unlocking instruction and the added conditional locking instruction is transmitted via a communication connection to a motor-vehicle-internal control device of the motor vehicle.
