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.
