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.

Disclosed are a hybrid vehicle torque adjusting method and device. The method includes: acquiring a requested torque of a front-axle engine and a requested torque of a rear-axle motor, determining a first compensation torque according to the filtered requested torque of the front-axle engine and an actual output torque of a front-axle transmission, and determining a target torque of the rear-axle motor according to the first compensation torque and the requested torque of the rear-axle motor. In the method, since a difference exists between the filtered requested torque of the front-axle engine and the actual output torque of the front-axle transmission during shifting of the front-axle transmission, after the difference is compensated by the rear-axle motor, a working condition that affects a dynamic performance of an entire vehicle can be eliminated, torques can be coordinated, and the dynamic performance of the entire vehicle can be improved.

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 military vehicle includes a chassis, a front end accessory drive (FEAD), and circuitry. The chassis includes an engine and an integrated motor generator (IMG). The FEAD includes multiple accessories and an electric motor-generator. The circuitry is configured to operate the military vehicle according to different modes. The circuitry is configured to receive a user input indicating a selected mode of the modes, and operate the chassis and the FEAD of the military vehicle according to the selected mode. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and the 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 system for adjusting performance of an electric motor in a hybrid vehicle during a combustion event. The system includes a combustion engine including a cylinder, an electric motor including an electric motor shaft and connected to the combustion engine via a drive shaft, and an inverter controller connected to the electric motor.
