Abstract: The vehicle includes a powertrain having an axle having a first drive wheel and a second drive wheel. A first gearbox may couple a first power source to the first drive wheel, and a second gearbox may independently couple a second power source to the second drive wheel. And, a controller may be configured to initiate a gear shift in the first gearbox and the second gearbox at different times.

Abstract: The power train of an electric vehicle includes an electric motor and a gearbox coupling the electric motor to a drive wheel. A controller may be configured to initiate a gear shift in the gearbox, and activate one or both of (a) a torque jog in electric motor, or (b) a burst of a pressurized fluid in an actuator to assist with the gear shift.

Abstract: A method of operating an electric vehicle having multiple electric traction motors include receiving a signal indicative of a driver requested torque, and determining portions of the torque request to produce from each traction motor based on efficiency maps of the motors. The method may also include producing the determined portions of torque from each motor.
