A system and method for power management of hybrid electric vehicles is provided. In some implementations, a plug-in series hybrid electric vehicle may include an engine, a motor/generator (MG), a traction motor, an energy storage device, and a controller. The controller is coupled to the engine and the MG to control operation of the engine and the MG such that a state-of-charge (SOC) of the energy storage device tracks a dynamic reference SOC profile during a trip and an average engine power (AEP) is maintained above a threshold. In some instances, maintaining AEP above a threshold supports emission control of the vehicle.

An embodiment method for controlling a hybrid vehicle includes driving a motor that starts an engine of the hybrid vehicle and controlling the motor to generate an engine starting torque to prevent a vibration of the engine, wherein the engine starting torque is generated by a feedforward control method. An embodiment device for controlling a hybrid vehicle includes a motor configured to start an engine of the hybrid vehicle, and a controller configured to drive the motor and control the motor to generate an engine starting torque to prevent a vibration of the engine, wherein the engine starting torque is generated by a feedforward control method.

A system and method for operating a hybrid vehicle that shuts down an internal combustion engine during idle and slow speed operations and instead drives a power transmission with an electric traction motor. A vehicle operating at higher speeds, under increased operating demands, or other operating conditions automatically switches from electric propulsion to internal combustion engine propulsion. This operational mode is configurable and at all times seamless to the driver and vehicle operations. By designating the low speed, low demand operation of the vehicle to the more efficient electric mode, fuel consumption can be reduced, and overall vehicle efficiency can be maximized.

A military vehicle including an engine coupled to the chassis for providing mechanical power to the military vehicle, a motor/generator coupled to the engine, and an energy storage system including a battery electrically coupled to the motor/generator. The military vehicle is operable in a silent mobility mode with the engine inactive and the energy storage system providing power to the motor/generator to operate the military vehicle. The motor/generator and the battery are sized such that electrical power generation through engine drive of the motor/generator is greater than the power depletion through operation of the military vehicle in the silent mobility mode. The motor/generator can charge the energy storage system while the military vehicle is driving or stationary.

A controller for a vehicle is configured to execute, when a state of charge of a battery is less than or equal to a threshold, a charging control to charge the battery with power that is generated by a motor generator using driving force of an internal combustion engine. The controller is also configured to obtain a temperature of the battery, set the threshold to a first threshold during a warm-up period, which is a period from a start of the internal combustion engine until the warm-up of the internal combustion engine is completed, set the threshold to a second threshold, which is greater than the first threshold, when the warm-up period ends, and set the second threshold to be greater when the temperature of the battery is a first temperature than when the temperature of the battery is a second temperature, which is higher than the first temperature.

When a vehicle is in a traveling state having a low necessity to quickly increase required traveling torque, high-rotational-speed engine starting unit that reduces an emission amount of particulate matter emitted during engine starting starts the engine. Since quick torque response is not required when the vehicle is in the traveling state having the low necessity to quickly increase the required traveling torque, the high-rotational-speed engine starting unit starts the engine, so that increase of the emission amount of particulate matter emitted during engine starting can be curbed.
