Abstract
A method for controlling a powertrain for a hybrid electric vehicle having an engine and a motor and gearing for establishing power flow paths from the engine and the motor with common gear elements to vehicle traction wheels. An engine power bias is applied to an engine power command and a bias to a motor torque command to avoid an operating mode in which motor torque is at or near zero, whereby gear rattle due to torque disturbances is avoided.
