Abstract
A powertrain comprising an engine, a motor, a disconnect clutch connected between the engine and the motor, and a transmission. The transmission is connected to the motor by a launch clutch and selectively and indirectly connected to the engine by the disconnect clutch. A controller receives an engine torque output signal and limits the torque output of the engine to the clutch capacity limit value. A system and a method are also provided for controlling a powertrain for a hybrid vehicle.
