Methods and systems are provided for rapidly charging a battery in a hybrid vehicle. In one example, a method includes charging a battery at a first rate via an engine transferring torque to a plurality of motor/generators while a vehicle speed is controlled based on a driver demand, and charging the battery at a second rate greater than the first rate via the plurality of motor/generators while the vehicle is autonomously controlled via a cruise control system. In this way, by charging the battery at the second rate while the vehicle speed is being controlled by the cruise control system, drivability issues related to engine torque production and/or motor/generator torque production may be minimized.

A method includes automatically operating an electrified vehicle in a noise reduction mode, via a control system of the electrified vehicle, if, based at least on noise restriction information and driver history information received by the control system, a current time and a current location of the electrified vehicle are appropriate for invoking the noise reduction mode.

A traction motor of a hybrid electric vehicle drives a primary pump to provide pressurized hydraulic fluid to engage a power flow path of a multi-ratio transmission. To reduce fuel consumption, the motor is maintained at zero speed until a shift lever is moved into a drive position. After a power flow path is established, the motor speed is again reduced to zero until a driver demands torque by pressing an accelerator pedal. While the traction motor is stationary, an auxiliary pump maintains the fluid pressure to keep the transmission power flow path engaged.

Method of engaging transmission system of a hybrid vehicle

Systems and methods for cranking an engine of a hybrid vehicle that includes an electric machine to crank the engine and propel the vehicle are disclosed. In one example, engine cranking speed and engine cranking source are selected in response to vehicle operating conditions that may affect whether or not an electrical power source has sufficient energy to crank the engine.
