Platooning Control Adjusting Vehicle Spacing for Weather Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current platooning control methods do not effectively account for weather or road conditions, making it difficult to manage urgent situations during emergent braking, which increases the risk of accidents.
Innovation Solution
An apparatus and method that determine a platooning level and control longitudinal and transverse vehicle-to-vehicle distances based on weather information, including road conditions, using a processor to assess weather states and adjust platooning sequences and vehicle spacing to enhance safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If platooning control is performed without considering weather or road conditions, then the control system is simple and easy to operate, but the safety of driving deteriorates during adverse weather
Solution Approach 1:
The system performs preliminary determination of weather environment states and road conditions before executing platooning control. The processor determines weather forecast information and measured road conditions in advance, then pre-determines appropriate platooning levels and vehicle spacing based on these conditions, ensuring safety measures are prepared before adverse weather impacts the platoon
Solution Approach 2:
The platooning control system dynamically adjusts the level of platooning and vehicle-to-vehicle spacing based on real-time weather conditions and road states. The processor modifies control parameters such as longitudinal and transverse distances according to the determined weather environment state, transitioning between different control modes (e.g., from tight formation to increased spacing) as conditions change
2Productivity
If vehicle-to-vehicle distance is reduced for efficient platooning, then productivity increases, but the risk of accident increases during emergent braking in bad weather
Solution Approach 1:
The system changes the parameter of vehicle-to-vehicle distance based on weather conditions. In normal conditions, the processor maintains smaller longitudinal and transverse distances for efficient platooning. When adverse weather is detected, the processor increases these distances to provide larger safety margins for emergent braking and maneuvering, thus adapting the spacing parameter to balance efficiency and safety
3Reliability
If platooning sequence is determined without considering braking force in bad weather, then the control process is simple, but the ability to cope with emergent braking deteriorates
Solution Approach 1:
The system applies local quality by determining platooning sequences based on specific local conditions - particularly the braking force characteristics of individual vehicles. The processor evaluates the braking capability of each vehicle in the platoon and assigns positions in the sequence accordingly, placing vehicles with stronger braking force in positions that require more aggressive deceleration responses to bad weather conditions

AI summary
An apparatus for controlling platooning based on weather information includes a processor configured to determine a weather environment state on a platooning path based on weather forecast information received from a control center or weather information measured by a vehicle sensor, determine a sequence of platooning based on the weather environment state, determine a level of the platooning based on the weather environment state, and perform control of a transverse vehicle-to-vehicle distance or control of a longitudinal vehicle-to-vehicle distance of a vehicle based on the measured weather information and the determined level of the platooning.
