A computer includes a processor and a memory storing processor-executable instructions. The processor is programmed to prevent a traction battery from providing power to a vehicle powertrain below a charge threshold, and then, upon one of (a) receiving an acceleration demand above an acceleration threshold and (b) predicting that a planned maneuver classified as high acceleration will occur within a time threshold, permit the traction battery to provide power to the vehicle powertrain below the charge threshold.

A transmission unit for a hybrid motor vehicle, has a planetary gearing. The planetary gearing is fitted with a first planetary wheel set and a second planetary wheel set. The transmission unit also includes an electric machine, which is coupled with a component part of the planetary gearing, and a plurality of switching devices, each of which forming a brake or a clutch, and each being movable between an activated position and a deactivated position. The switching devices are operatively installed for switching various transmission ratios between an input, which can be coupled with an internal combustion engine, and an output, and/or between the electric machine and the output. No more than four switching devices are present for implementing at least two different transmission ratios in a drive state of the internal combustion engine, at least one transmission ratio in a drive state of the electric machine, and at least one transmission ratio in a recuperation state of the electric machine, as a result of their activated and deactivated positions.

A hybrid electric vehicle comprises a set of wheels, a mechanical transmission adapted to provide torque to the set of wheels, an electric motor coupled to and providing motive force to the mechanical transmission, battery storage coupled to and supplying electrical power to the electric motor, and a gasoline compression ignition (GCI) engine coupled to at least one of the mechanical transmission and the electric motor so as to provide mechanical energy to the mechanical transmission and energy for operating the electric motor.

A controller and a control method for a hybrid electric vehicle are provided. An internal combustion engine and a first rotating electric machine are capable of applying power to a driven wheel via a power split device. A deactivating process deactivates combustion control in a deactivated cylinder that corresponds to one or more of cylinders of the internal combustion engine. A first compensation process sets, when the deactivating process is executed, torque of the first rotating electric machine to be larger than torque of the first rotating electric machine obtained prior to starting the deactivating process so as to compensate for at least some of a decrease amount of torque of the internal combustion engine resulting from the deactivating process.

A waste heat recovery (WHR) hybrid power system can be utilized in vehicles to convert heat energy into mechanical energy. The WHR system can include a WHR power unit structured to convert thermal energy into rotation of a WHR drive shaft. A motor/generator having a motor/generator shaft can selectively operate as a motor or a generator. A mechanical linkage can be structured to selectively link a output shaft to one of the WHR drive shaft and the motor/generator drive shaft independently of the other of the WHR drive shaft and the motor/generator drive shaft.

A transmission assembly for a work vehicle having an engine includes a variator operably connected to the engine, a gear arrangement configured to provide a selective gear reduction for transmission of output power from the variator to an output shaft, and an electrical machine unit. The electrical machine unit further includes a main shaft operably connected to the variator, a first rotor configured to rotatably drive a first shaft, a second rotor configured to rotatably drive a second shaft, and a clutch configured to selectively couple the first shaft or the second shaft, or both the first shaft and the second shaft, to the main shaft. The clutch, the first rotor, and the second rotor are operable to control a speed and rotational direction of the main shaft in providing rotational power to the variator.

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.
