Automated Platooning Control with Dynamic Leader Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated driving systems, particularly at Level 3 and Level 4, are limited in operational design domains and require human intervention when conditions change, such as lane reduction or inclement weather, leading to inefficiencies and reduced riding comfort in cargo-type vehicles.
Innovation Solution
An automated platooning system that dynamically switches between leader vehicles using Vehicle-to-Everything (V2X) communication, allowing for autonomous driving by selecting a new leader vehicle when conditions become unfavorable, ensuring continuous operation without human intervention and maintaining riding comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated driving operates at Level 3-4 with fixed ODD, then system reliability is improved, but adaptability deteriorates when conditions change
Solution Approach 1:
The patent implements dynamic switching between multiple leader vehicles based on real-time operational conditions. When the current leader vehicle can no longer maintain safe operating conditions (e.g., lane reduction, heavy rain), the automated vehicle dynamically switches to a new leader vehicle, enabling continuous adaptive operation without human intervention and resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The system changes operational parameters by transitioning between different driving modes (platooning mode with leader vehicle association and autonomous mode without association) based on environmental conditions. This parameter change allows the system to maintain reliability across varying conditions by adjusting its operational state.
2Reliability
If control is handed over to driver or stopped via MRM, then safety is improved, but productivity deteriorates due to human intervention requirements
Solution Approach 1:
The automated vehicle performs self-service by automatically switching between leader vehicles when operational conditions change. Instead of requiring human driver intervention or stopping via MRM, the system autonomously manages its own operation continuity by selecting new leader vehicles, thereby maintaining both safety and productivity without human involvement.
Solution Approach 2:
The patent ensures continuous useful action by implementing seamless transitions between leader vehicles. When the current leader becomes unsuitable, the system continuously maintains automated driving operation by switching to an alternative leader vehicle, eliminating interruptions and maintaining productivity while preserving safety through automated decision-making.
3Adaptability or versatility
If Level 5 autonomous driving is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the complex Level 5 autonomous driving function into manageable components: platooning mode with leader association, autonomous mode without association, and dynamic switching logic. By dividing the overall system into these functional segments, the implementation complexity is reduced while maintaining full operational flexibility across different conditions.
