Abstract
The present invention broadly comprises a method for controlling engine speed, engine torque, and torque converter output including the steps of applying engine torque to a torque converter and modulating the transferring of the torque to a pump for the torque converter. In some aspects, the torque converter further comprises a pump clutch and the method applies torque to the pump clutch and controllably slips the pump clutch. In some aspects, the method supplies engine torque from an engine with a turbocharger and controllably slips the pump clutch to increase speed and torque for the engine during a launch event for the vehicle or determines a parameter regarding operation of the vehicle and controllably slips the pump clutch responsive to the parameter. The present invention also comprises a method for controlling torque converter output by connecting a clutch between an engine and a torque converter and controllably slipping the clutch.
