  • Patent number: 11186181
    Abstract: A drive system with one or more electrically driven axles, a transmission subsystem, which is drivingly coupled to the drive gearbox of each of the electrically driven axles, synchronous and asynchronous motors, which are each drivingly coupled to the transmission subsystem, and a controller. Each of the axles has a drive gearbox that transmits rotary power to an associated set of vehicle wheels. The controller controls the synchronous motor and/or the asynchronous motor responsive to at least a torque request and a shaft speed of the synchronous motor and/or the shaft speed of the asynchronous motor. Over a significant portion of the operating range of the drive system, the controller is configured to vary the respective magnitudes of the rotary power provided by the motors to satisfy the torque request in a manner that maximizes a combined efficiency of the motors in a predetermined manner.
