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.

Methods and systems are provided for operating a driveline of a hybrid vehicle during conditions when a temperature of a motor/generator is increasing. In one example, a method is provided that adjusts engine speed as a function of motor/generator temperature while maintaining engine power output when driver demand wheel power is constant.

A vehicle powertrain includes a battery, an electric machine, an electrical circuit, an electrical outlet, and a controller. The electric machine is configured to receive electrical power from the battery to propel the vehicle and to deliver electrical power to the battery to recharge the battery. The electrical circuit is configured to transfer electrical power between the battery and the electric machine. The electrical outlet is configured to deliver power from the electrical circuit to an external device that is connected to the outlet. The controller is programmed to, in response to a first set of conditions that is indicative of the vehicle powertrain overheating or a second set of conditions that is indicative of an inability to charge the battery to a requested charge value, issue a warning of an impending shutdown of the electrical outlet.

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.

A military vehicle includes a chassis, a front axle, a rear axle, an energy storage system, a first driver, a transmission, and a second driver. The chassis includes a passenger capsule, a front module coupled to the passenger capsule, and a rear module coupled to the passenger capsule. The passenger capsule defines a tunnel extending longitudinally along a bottom thereof. The front axle is coupled to the front module. The rear axle is coupled to the rear module. The first driver is supported by the front module. The transmission is positioned within the tunnel and coupled to the front axle and/or the rear axle. The second driver is at least partially positioned within the tunnel and positioned between the first driver and the transmission. The second driver includes a motor/generator coupled to the transmission and a clutch positioned to selectively couple the first driver to the motor/generator.

A driveline for a military vehicle includes a driver. The driver includes a housing, a motor/generator, and a clutch. The housing includes an engine mount configured to couple to an engine and a backing plate configured to couple to a transmission. The motor/generator is disposed within the housing and configured to couple to an input of the transmission. The clutch is disposed within the housing and coupled to the motor/generator. The clutch is configured to selectively couple an output of the engine to the motor/generator. The clutch is spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto.

An example method includes making a first determination that a load of a cooling system of a vehicle is expected to increase and become greater than a capacity of the cooling system; operating, in response to making the first determination, the vehicle in a first mode where a combustion engine and an electric motor operate such that a charge level of a power supply of the vehicle increases or is maintained above a threshold charge level; making, after operating the vehicle in the first mode, a second determination that the load of the cooling system has become greater than the capacity of the cooling system; and operating, in response to making the second determination, the vehicle in a second mode where the combustion engine and the electric motor operate such that the charge level of the power supply decreases or is maintained below the threshold charge level.

A cooling system includes a circulation channel, a first switching valve, a second switching valve, and a controller. The circulation channel allows a cooling medium to circulate in order of a radiator, a battery, an inverter, a motor, and the radiator. The first switching valve allows the cooling medium to bypass the radiator in the circulation channel. The second switching valve allows the cooling medium to bypass the motor in the circulation channel. The controller controls the first switching valve and the second switching valve on the basis of a battery temperature of the battery, an inverter temperature of the inverter, and a motor temperature of the motor.

A vehicle includes a gear mechanism connected to a driving wheel; a traveling electric motor configured to exchange heat with a heat exchange medium shared by the gear mechanism and output motive power to the driving wheel via the gear mechanism; and a controller configured to change an operating point of the traveling electric motor to a stronger field side rather than a maximum efficiency point in a case that a temperature of the heat exchange medium is less than a predetermined temperature.

Methods and systems are provided for providing thermal management for components of a vehicle. In one example, a method may include exchanging heat between different coolant systems via a heat exchanger using predicted data indicating estimated coolant temperatures for a vehicle trip and measured data indicating dynamic conditions for the vehicle trip.
