Platooning Control System for Independent Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional platooning systems, following vehicles are unable to independently respond to dangerous situations, as they are solely controlled by the leading vehicle, which can lead to shared risk in collision scenarios.
Innovation Solution
A system where the leading vehicle predicts collisions and transmits information to following vehicles, allowing them to independently control braking, lane changes, or withdrawal from the platooning group based on their ability to avoid collisions, enabling each vehicle to establish its own avoidance strategy.

Engineering Contradiction Analysis
1Reliability
If the leading vehicle controls all vehicles in the platooning group, then the control structure is simple and centralized, but the following vehicles cannot independently respond to dangerous situations, increasing collision risk
Solution Approach 1:
The patent divides the centralized control function into segments: the leading vehicle retains control authority for normal operations, but following vehicles are empowered with independent emergency response capability. This segmentation allows the following vehicle to autonomously execute collision avoidance maneuvers (braking, lane changing) when danger is detected, while the leading vehicle maintains overall platooning coordination. The control system is thus split between centralized (normal operation) and decentralized (emergency response) modes.
Solution Approach 2:
The following vehicle is pre-equipped with collision avoidance algorithms and decision-making capabilities that are activated only when necessary. The system performs preliminary preparation by pre-calculating emergency response strategies (braking distance, lane change feasibility) and storing them ready for immediate execution. This allows the following vehicle to respond instantly to dangerous situations without waiting for leading vehicle commands, while maintaining simple centralized control during normal operations.
2Reliability
If the following vehicle independently responds to dangerous situations, then collision avoidance capability is improved, but communication coordination between vehicles becomes more complex
Solution Approach 1:
The patent implements a feedback mechanism where the following vehicle communicates its emergency response status and detected dangers back to the leading vehicle. After the following vehicle independently executes collision avoidance maneuvers, it sends feedback information (e.g., emergency braking activated, lane change performed) to the leading vehicle. This feedback loop allows the leading vehicle to maintain situational awareness and update the platooning group's state information, preventing communication loss while enabling independent response.
Solution Approach 2:
The patent uses V2V communication as an intermediary channel to coordinate between the leading and following vehicles during emergency situations. The communication system transmits critical information (danger detection, emergency response status, collision avoidance outcomes) between vehicles, ensuring that independent following vehicle actions do not create information loss. The intermediary communication layer maintains coordination without requiring complex centralized control during emergencies.

AI summary
A system for controlling platooning includes a leading vehicle and a following vehicle. The leading vehicle predicts a collision with an external object located in front of a driving lane of the leading vehicle, determines a possibility that the leading vehicle will avoid the collision based on a situation of a neighboring lane adjacent to the driving lane, and transmits information associated with the collision to the following vehicle based on the possibility that the leading vehicle will avoid the collision. The leading vehicle determines a possibility that the following vehicle will avoid its collision based on a situation of the neighboring lane and controls at least a portion of braking of the following vehicle, a lane change of the following vehicle, a change of a vehicle the following vehicle will follow, or withdrawal of the following vehicle from a platooning group.
