ABSTRACT:
A system is provided for controlling the operation of powertrain, including an engine and a torque converter having a torque converter clutch. The system may include a torque governor for controlling a torque output of the engine and a speed governor for controlling a rotational speed of the engine. The system may further include a powertrain controller operable to receive a command selecting between first and second modes of operation. If the command indicates the first mode of operation, the powertrain controller may enable the torque governor and control the torque converter clutch to operate in accordance with a first clutch profile. If the command indicates the second mode of operation, the powertrain controller may enable the speed governor and control the torque converter clutch to operate in accordance with a second clutch profile that is different from the first clutch profile.
