Abstract:
A method for controlling a vehicle powertrain during launch includes controlling slip across a first clutch that transmits engine torque through the first clutch and the current gear while a transmission operates in a current gear other than a launch gear, disengaging the first clutch, engaging the launch gear, and controlling slip across a second clutch that transmits engine torque through the second clutch and the launch gear.
