Abstract
Methods and systems are provided for a vehicle. In one example, a method for the vehicle includes adjusting an output torque of an electric machine to produce a desired vehicle speed and direction of propulsion while operating an auxiliary load powered via the transmission. The output torque may be adjusted while disengaging clutches of a transmission or a service brake to mechanically unlock an output shaft of the transmission. The first electric machine may be operated in a speed control to learn an amount to torque to hold the vehicle speed at zero and the amount of learned torque may be superimposed with an amount of requested torque upon vehicle launch.
