As the United States Army strives for electrification and hybridization of tactical and combat vehicles in alignment with its Climate Strategy, it is necessary to capture all aspects of the drive cycle. One key area for consideration is the amount of time that the vehicles spend idling. Indeed, military vehicles can idle for a considerable amount of time, especially given that soldiers must keep their vehicles running to power critical electronic subsystems. Current, standardized drive cycles do not fully capture the degree that military vehicles idle. This study begins to address this gap by analyzing geo-location data collected from the National Training Center (NTC) for several different tactical vehicles including the High Mobility Multipurpose Wheeled Vehicle (HMMWV), the Bradley Fighting Vehicle, and the Abrams Main Battle Tank. This paper details the extraction, cleaning, and analysis of the geo-location data.

As the global automotive market shifts towards electric vehicles, the United States Army must naturally consider this alternative for its combat vehicles. Indeed, electric vehicles offer numerous tactical advantages over traditional diesel engines, including higher torque at lower speeds and lower signature. Unfortunately, full electrification of most military vehicles is not feasible due to the weight of the requisite battery pack. However, the Army can take advantage of electric vehicles through hybrid power trains. Hybrid options allow for quiet, resilient, and powerful vehicles that are less constrained by battery technology. This study looks at the feasibility of hybrid power systems for military vehicles including the Infantry Squad Vehicle, the High Mobility Multipurpose Wheeled Vehicle, and the Joint Light Tactical Vehicle.
