A system and method for controlling a hybrid vehicle having an engine and a traction motor include operating the engine at an operating point selected based on system efficiency, operating the electric machine to provide an electric machine torque responsive to a difference between a driver demand torque and the engine torque associated with the operating point, and limiting a rate of change of the electric machine torque in response to a rate of change of the driver demand torque. The electric machine torque rate limit may vary continuously responsive to the rate of change of driver demand torque and whether the driver demand torque is increasing or decreasing.
