Platooning Vehicle Control with Dynamic Sensing Range Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In platooning scenarios, following vehicles often face difficulties in receiving driving information from the leader vehicle, leading to inefficient communication resource usage and potential disruptions in the formation of the platooning group, as the leader vehicle expends many communication resources sensing and sharing data with multiple followers.
Innovation Solution
A vehicle control device that dynamically recalculates and allocates sensing ranges for each vehicle based on the arrangement pattern, ensuring non-overlapping sensing areas and considering factors like driving direction and sensing performance, allowing each vehicle to focus on a specific area and conserve communication resources.

1Reliability
If the leader vehicle senses and shares data with multiple following vehicles through V2V communication, then the platooning formation can be maintained, but the communication resources are excessively consumed
Solution Approach 1:
The sensing area is divided and allocated to different vehicles within the platooning group. Each vehicle is assigned a specific sensing range (first sensing area for leading vehicle, second sensing area for following vehicles) to monitor. This segmentation eliminates redundant sensing by the leader vehicle and distributes the sensing burden across multiple vehicles, thereby reducing communication resource consumption while maintaining formation stability.
Solution Approach 2:
Different vehicles are assigned different sensing responsibilities based on their positions in the platooning formation. The leading vehicle focuses on front sensing while following vehicles monitor their respective rear or side areas. This local quality approach ensures that each vehicle optimizes its sensing resources for its specific role, reducing overall system communication overhead.
2Loss of information
If the leader vehicle monitors the entire surrounding area, then complete situational awareness is achieved, but the communication load increases significantly
Solution Approach 1:
The complete sensing area around the platooning group is segmented into multiple zones, with each zone assigned to a specific vehicle for monitoring. The leading vehicle monitors the front zone, while following vehicles monitor their respective zones. This segmentation ensures complete situational awareness is maintained across the entire platooning formation while distributing the communication load to prevent any single vehicle from being overwhelmed.
3Productivity
If following vehicles receive driving information from the leader vehicle, then platooning coordination is achieved, but vehicles with poor sensing performance cannot effectively contribute to the platooning group
Solution Approach 1:
Vehicles are assigned sensing responsibilities based on their individual sensing capabilities and positions within the platooning formation. Vehicles with better sensing performance are assigned larger or more critical sensing areas, while vehicles with poorer sensing performance are assigned smaller or less critical areas. This local quality approach allows all vehicles to contribute effectively according to their capabilities, improving overall platooning coordination efficiency without excluding any vehicle.
