A vehicle propulsion system configured to generate wheel torque includes an engine arranged to output a first propulsion torque to a transmission and an electric motor arranged to output a second propulsion torque downstream of the transmission. The vehicle propulsion system also includes a controller programmed to, in response to detecting a lash crossing associated with one of the electric motor and the transmission, set a torque slew rate of the other one of the electric motor and transmission such that each of the electric motor and transmission undergoes lash crossings at different points in time.
