Abstract: A system and method for controlling a fraction motor in a hybrid vehicle includes varying a traction motor torque in response to an engine cylinder misfire. The traction motor torque is varied to compensate for an engine torque shortfall due to the engine cylinder misfire, reducing a torque imbalance caused by the misfire.

Abstract: A hybrid electric vehicle includes an engine and an electric machine, both capable of providing torque to transmission gearing. A clutch is disposed between the engine and the electric machine and is configured to selectively couple the engine to the electric machine. At times in which control of the amount of engine torque transmitted to the gearing is desirable, a controller is programmed to slip the clutch. If the controller is able to determine the amount of torque transmitted through the slipping clutch, the controller alters an output of the electric machine based upon the torque through the clutch. If, however, the controller is unable to determine the amount of torque transmitted through the slipping clutch, the controller alters the output of the electric machine based upon an acceleration of the electric machine.
