Abstract

Inter-vehicle platoon distance management is provided. Parameters relating to external conditions are used together with vehicle physical characteristics, performance information, and other factors toselect an optimized distance between vehicle pairs traveling as a platoon. The parameters relating to the external conditions are aggregated by the following vehicle of the platoon vehicle pair, andused to adjust or otherwise modify a predetermined minimum following distance parameter. This allows flexibility in the platooning control to follow at different distances while maintaining an overallfuel economy benefit of the platoon. When no external condition restrictions exist, the platoon vehicles follow at the shortest distance to maximize fuel economy. However, as the aggregated externalconditions increase, the platooning distance is extended to improve safety while preserving as much fuel economy benefit of the platoon as possible.

Description

technical field [0001] Embodiments herein relate generally to highway vehicle fleet management. More specifically, certain embodiments relate to platoon-to-vehicle distance management, wherein parameters related to ambient platoon conditions are aggregated by the vehicles of the platoon and used to adjust or otherwise modify predetermined minimum following distance or spacing parameters in order to maximize safety performance while still providing improved fuel savings and other efficiency benefits provided by queue participation. Although the invention will be described with reference to these specific example embodiments, it should be understood that the claimed invention is applicable to other applications as well. [0002] Cross References to Related Applications [0003] This application is related to the following U.S. Patent Application: U.S. Patent Application Serial No. 15 / 395,219, filed December 30, 2016, and entitled "Self-Sequencing of Fleet Vehicles in Queue" (A...
