Abstract

A driveline for a military vehicle includes an engine, an energy storage system, an accessory drive coupled to the engine, a transmission configured to couple to at least one of a front axle or a rear axle of the military vehicle, a second motor coupled to the transmission and electrically coupled to the energy storage system, and a clutch positioned between the engine and the second motor. The accessory drive includes an air compressor and a first motor. The first motor is electrically coupled to the energy storage system. The clutch is spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto based on operation of the air compressor. The driveline is operable in a plurality of modes including an engine-only mode and an electric-only mode.
