  • Patent number: 7243011
    Abstract: A launch system for a hybrid vehicle includes a pump, an electronic throttle, a sensor, and a hybrid control module. The pump is driven by an internal combustion engine and provides pressurized fluid to a transmission. The electronic throttle selectively adjusts airflow to the internal combustion engine and current to an electric motor. The sensor detects when a brake pedal has been released. The hybrid control module increases pressure of the pressurized fluid and limits torque transfer from at least one of the internal combustion engine and the electric motor when the sensor detects that the brake pedal has been released until a predetermined condition has been met. The hybrid control module increases pressure of the pressurized fluid with the pump by increasing the revolutions of the internal combustion engine and limits torque to the transmission by retarding the responsiveness of the electronic throttle.
