A control system for operating a military vehicle according to different modes includes processing circuitry that receives a user input indicating a selected mode of the different modes, and operates a driveline and a front end accessory drive (FEAD) of the military vehicle according to the selected mode. The driveline of the military vehicle includes an engine and an integrated motor generator (IMG) and the FEAD includes multiple accessories and an electric motor-generator. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and drives tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.

A vehicle gear-shifting control apparatus is equipped with an engine, a motor, an automatic transmission, a friction brake system, and a controller which executes, during deceleration of a vehicle during which the friction brake system is distributing a braking force to front and rear wheels, a regeneration control of imparting a regenerative braking torque to the rear wheels by causing the motor to perform a regeneration operation and a gear-shifting control of changing a shift stage of the automatic transmission by outputting a gear-shifting signal in accordance with the rotation speed of an input shaft to the automatic transmission. When the controller determines an oversteered state of the vehicle during the regeneration control, the controller increases an input torque of the input shaft so that the regenerative braking torque decreases while maintaining the regeneration operation of the motor and, at the same time, limits the gear-shifting control.

A hybrid electric vehicle includes an engine, a first motor directly connected to the engine, an engine clutch, a second motor selectively connected to the first motor through the engine clutch, a transmission directly connected to the second motor, a transmission controller configured to determine whether the transmission needs to be shifted, and a hybrid controller configured to compare a target torque reduction with intervention limits of the first and second motors when the engine clutch is in a locked-up state, to set torque reduction amounts of the engine, the first motor, and the second motor, respectively, and to output a torque command for controlling the torques of the engine, the first motor, and the second motor, respectively.

A military vehicle includes a cab having a rear wall, a bed positioned behind the cab, and an energy storage system. The energy storage system includes a lower support coupled to the bed, a battery supported by the lower support, a bracket coupled to the batter, and an isolator mount coupling the bracket to the rear wall. The isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the rear wall.

A military vehicle includes a chassis, a front axle, a rear axle, an energy storage system, an engine, a transmission, and a motor. The chassis includes a passenger capsule, a front module coupled to a front end of the passenger capsule, and a rear module coupled to a rear end of the passenger capsule. The passenger capsule defines a tunnel extending longitudinally along a bottom thereof. The front module includes a front subframe assembly. The rear module includes a rear subframe assembly. The front axle is coupled to the front subframe assembly. The rear axle is coupled to the rear subframe assembly. The engine is supported by the front subframe assembly. The transmission is positioned within the tunnel and coupled to the front axle and/or the rear axle. The motor is at least partially positioned within the tunnel and positioned between the engine and the transmission.

A military vehicle includes an engine, an energy storage system, an accessory drive coupled to the engine and including an air compressor and a first motor, a second motor coupled to an axle, and a clutch positioned between the engine and the second motor. 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. In an engine mode, (i) the clutch does not receive the air supply such that the engine is coupled to the second motor and (ii) the engine drives (a) the accessory drive and (b) the axle through the second motor. In the electric mode, (i) the first motor drives the air compressor to compress air to facilitate supplying the air supply to the clutch to disengage the clutch and decouple the engine from the second motor and (ii) the second motor drives the axle.

A military vehicle includes a cab having a rear wall, a bed positioned behind the cab, and an energy storage system. The energy storage system includes a lower support coupled to the bed, a battery supported by the lower support, a bracket coupled to the batter, and an isolator mount coupling the bracket to the rear wall. The isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the rear wall.

A driveline including a motor/generator configured to receive power from an engine and output power to a tractive element, an accessory drive configured to receive power from the engine and output power to an accessory, and an energy storage system including a battery, the energy storage system electrically coupled to the motor/generator and the accessory drive. The driveline is operable in a charge mode with the motor/generator and the accessory drive providing electrical power to the energy storage system. The driveline is operable in a silent mobility mode with the energy storage system providing electrical power to the motor/generator and the accessory drive to operate the military vehicle.

A driveline includes an engine, a transmission configured to couple to an axle of the electrified military vehicle, a tractive motor coupled to the transmission, an engine clutch positioned between the engine and the tractive motor, and an accessory drive. The accessory drive includes an accessory motor, an accessory clutch including a first portion and a second portion, an accessory coupled to the first portion, a first belt coupling the first portion to the accessory motor, and a second belt coupling the second portion to the engine.

A military vehicle including a chassis, an engine, a motor/generator, and an energy storage system. The chassis including a passenger capsule including a rear wall, and a rear module coupled to the passenger capsule. The rear module including a rear subframe assembly, a left rear wheel well, a right rear wheel well, and a bed. The engine coupled to the chassis for providing mechanical power to the military vehicle and the motor/generator coupled to the engine. The energy storage system including a lower support coupled to the bed, a lower isolator mount coupled to the lower support, a battery electrically coupled to the motor/generator and coupled to the isolation mounts such that the weight of the battery is supported via the lower isolator mount and the lower support, a bracket coupled to the battery, and an upper isolator mount coupling the bracket to the rear wall of the passenger capsule.
