Solution Overview

Problem

Existing platooning systems fail to prevent accidents due to operational errors in vehicles during autonomous driving, as they do not initially check the functional state of vehicles before forming a platoon, leading to potential accidents from unverified vehicle functions.

Innovation Solution

A platooning control apparatus and method that includes a communication device and controller to check the synchronization of functional operations, such as lamp, deceleration, acceleration, and steering, of following vehicles after a platoon is formed, determining whether these operations are within normal ranges and releasing the platoon if abnormalities are detected, using V2X communication to ensure safe vehicle-to-vehicle communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If platoon is formed immediately after communication link is established between vehicles, then platoon formation speed is improved, but safety is worsened due to unverified vehicle functions

Engineering Contradiction:
Improveplatoon formation timeVSAvoidvehicle function reliability
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system performs preliminary function verification of all vehicles (lamps, deceleration, acceleration, steering, automatic platooning releasing function) before finalizing platoon formation. This preliminary action ensures that all vehicles are operationally ready and synchronized, preventing safety issues while maintaining efficient formation through automated pre-checks.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If function verification is performed for all vehicles before platoon formation, then safety is improved, but platoon formation time is worsened

Engineering Contradiction:
Improveplatoon operation safetyVSAvoidplatoon formation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Each vehicle autonomously performs self-verification of its own functions (lamps, deceleration, acceleration, steering, automatic platooning releasing function) and reports status to the leading vehicle. This self-service approach distributes the verification burden, enabling comprehensive safety checks without significantly increasing overall formation time.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements real-time feedback mechanisms where vehicles report their functional status and synchronization information to the leading vehicle. This continuous feedback allows the platoon controller to monitor and verify all functions efficiently, ensuring safety while maintaining formation speed through information sharing.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If driver concentration is reduced during platooning, then ease of operation is improved, but response to functional errors is worsened

Engineering Contradiction:
Improvedriver workloadVSAvoiderror response capability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system replaces mechanical driver response with automated electronic monitoring and control systems. The automatic platooning releasing function and controller continuously monitor vehicle functions and communicate with the leading vehicle, providing automated error detection and response that compensates for reduced driver attention while maintaining safety.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A platooning control apparatus includes: a communication device configured to perform communication between a leading vehicle and following vehicles, which follow the leading vehicle, in a platoon; and a controller configured to control platooning by requesting checking of functions of the following vehicles through the communication device after the platoon is formed, by identifying whether a specific function among checked functions of the following vehicles operates, and by determining whether the platoon is maintained according to an identification result.
