A hybrid vehicle includes an engine, an electric machine, a disconnect clutch configured to selectively couple the engine to the electric machine, a transmission having an input shaft operably coupled to the electric machine and an output shaft operably coupled to a driveline, and a controller programmed to, in response to (i) the disconnect clutch being disengaged and (ii) a speed difference between the input and output shafts being less than a threshold, limit torque commanded to the electric machine to a value that is less than a rated torque of the electric machine regardless of driver-demand torque, and further programmed to, in response to (i) the disconnect clutch being disengaged, (ii) a request to start the engine, and (iii) the speed difference exceeding the threshold, permit a torque command to the electric machine that exceeds the value to reduce the speed difference between the input and output shafts.
