Abstract
A method for operating a vehicle including a hybrid powertrain system includes enabling a commanded electric vehicle (EV) launch when a high-voltage battery state-of-charge (SOC) is greater than an SOC threshold, a transmission output speed is less than a low speed threshold, a transmission output torque is less than a speed-based torque threshold, and an operator torque request is achievable in the EV traction mode. An EV traction mode is employed to execute the commanded EV launch in response to the operator torque request including a launch maneuver.
