  • Method and apparatus for controlling a hybrid powertrain system
    Patent number: 10099683
    Abstract: A method for controlling a hybrid powertrain system includes determining an operator-selected mode and a charging mode for the energy storage device. A first speed/load region at which the internal combustion engine is in an OFF state is determined for the operator-selected mode and the charging mode for the energy storage device, wherein the first speed/load region is defined by output torque and vehicle speed. A second speed/load region includes a preferred speed that is selected for operating the internal combustion engine is determined for the operator-selected mode and the charging mode for the energy storage device. The preferred engine speed is substantially imperceptible in a passenger compartment of the vehicle. The internal combustion engine is operated at the preferred engine speed that is imperceptible in the passenger compartment when the output torque request and the present vehicle speed are within the second operating region.
