  • Efficiency optimization of multi-motor electric vehicles
    Patent number: 11639114
    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.

  • Controlling the powertrain of a vehicle
    Patent number: 10538231
    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.
