Inter-vehicle platoon distance management is provided. Parameters relating to external conditions are used together with vehicle physical characteristics, performance information, and other factors to select 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, and used 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 overall fuel 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 external conditions increase, the platooning distance is extended to improve safety while preserving as much fuel economy benefit of the platoon as possible.
