Vehicle Terminal Timing Control to Prevent VIN Request Collisions

Solution Overview

Problem

Communication collisions occur between telematics and eCall terminals in vehicles due to simultaneous requests for vehicle identification information, leading to erroneous determinations and prevention of telematics services.

Innovation Solution

Implementing a staggered timing system for request messages from telematics and eCall terminals, with different preset periods for requesting vehicle identification information, and determining the receiving object of diagnostic success messages to avoid collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If both telematics terminal and eCall terminal request vehicle identification information simultaneously, then both terminals can obtain the information, but communication collision occurs preventing service provision

Engineering Contradiction:

Improveservice provision reliabilityVSAvoidcommunication collision

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system performs preliminary actions by having the eCall terminal request vehicle identification information before the telematics terminal. This staged approach prevents communication collisions by ensuring the eCall terminal receives necessary information first, allowing subsequent telematics requests to be properly differentiated and handled without conflict.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments the request timing for different terminals. The eCall terminal operates in an earlier time window (first preset period) while the telematics terminal operates in a later time window (second preset period). This temporal segmentation eliminates communication collisions by ensuring requests are processed in distinct phases.

Inventive Principle:

Principle #1Segmentation

2Productivity

If telematics terminal requests vehicle identification information early, then service can be provided promptly, but communication collision with eCall terminal increases

Engineering Contradiction:

Improveservice provision speedVSAvoidcommunication collision

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The system performs preliminary actions by having the eCall terminal request vehicle identification information before the telematics terminal. This staged approach prevents communication collisions by ensuring the eCall terminal receives necessary information first, allowing subsequent telematics requests to be properly differentiated and handled without conflict.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements periodic action through structured time windows. The eCall terminal requests information during the first preset period, while the telematics terminal requests during the second preset period. This periodic, time-separated approach maintains productivity while eliminating communication collisions.

Inventive Principle:

Principle #19Periodic action

3Productivity

If telematics terminal determines diagnostic communication without proper timing differentiation, then communication efficiency improves, but erroneous determination of diagnostic success occurs

AI summary

A vehicle includes a first communication terminal; a second communication terminal; and a controller configured to transmit vehicle identification information of the vehicle to the first communication terminal or the second communication terminal according to a request from the first communication terminal or the second communication terminal. The first communication terminal is configured to transmit, to the controller, a first request message for requesting the vehicle identification information at a first point in time that a first preset period of time has elapsed from a point in time that an ignition of the vehicle was turned on. The second communication terminal is configured to transmit, to the controller, a second request message for requesting the vehicle identification information at a second point in time that a shorter second preset period of time has elapsed from the point in time that the vehicle's ignition was turned on.
