METHOD TO REDUCE POWERTRAIN NOISE AND VIBRATION DURING ENGINE START IN HYBRID VEHICLE
A method of controlling a powertrain system of a hybrid vehicle includes detecting a request to start an engine, incrementally applying torque to the powertrain system, and biasing the torque against a static member of the powertrain system, such as a parking pawl of a transmission when the transmis...

Summary: | A method of controlling a powertrain system of a hybrid vehicle includes detecting a request to start an engine, incrementally applying torque to the powertrain system, and biasing the torque against a static member of the powertrain system, such as a parking pawl of a transmission when the transmission is disposed in a parking position, to remove lash from the powertrain system prior to starting the engine. |
