Platooning Filter Regeneration Control

Solution Overview

Problem

During vehicle platooning, the regeneration of filters such as diesel particulate filters (DPF) can cause high-temperature exhaust gases and increased RPM, potentially damaging following vehicles and reducing the accuracy of RPM-based control.

Innovation Solution

An apparatus and method for regenerating filters in vehicle platooning, which includes a communication circuit, a filter, and a controller that determines the need for filter regeneration based on soot amount and vehicle position, allowing for controlled regeneration after reaching a destination or by adjusting vehicle position to prevent heat damage to neighboring vehicles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If filter regeneration is performed during vehicle platooning, then the filter is cleaned and PM emissions are reduced, but high-temperature exhaust gases may damage following vehicles and increased RPM reduces control accuracy

Engineering Contradiction:

Improvefilter performanceVSAvoidheat damage to following vehicles

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts vehicle behavior and regeneration timing based on real-time platooning conditions. The controller monitors vehicle position, distance to following vehicles, and platooning status to determine optimal regeneration moments, making the system adaptable rather than static

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs preliminary checks of platooning conditions before initiating filter regeneration. It evaluates distance to following vehicles, vehicle order in platoon, and remaining distance to destination beforehand to prevent harmful effects, ensuring safe regeneration conditions are met before activation

Solution Approach 1:

The system dynamically adjusts vehicle behavior and regeneration timing based on real-time platooning conditions. The controller monitors vehicle position, distance to following vehicles, and platooning status to determine optimal regeneration moments, making the system adaptable rather than static

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system extracts the regeneration operation from the normal platooning flow by delaying it until safe conditions are met. It separates the filter regeneration function from the continuous platooning operation, allowing regeneration to occur only when it won't harm following vehicles

AI summary

The present disclosure provides an apparatus and method for maneuver platooning of a vehicle. The apparatus may include a communication circuit that communicates with one or more external vehicles included in a vehicle platooning group together with the vehicle, a filter that filters particulate matter generated by the vehicle, and a controller electrically connected with the communication circuit. The controller is configured to control at least one of a behavior of the vehicle or a regeneration of the filter based on information about an order of the vehicle in the vehicle platooning group, when the controller determines that regenerating the filter is required.
