  • Publication number: 20240109432
    Abstract: Methods and systems are provided for an electric drive train of a vehicle. In one example, a four-node planetary gear set is included in the electric drive train with a first motor coupled to a first input node and a second motor coupled to a second input node of the four-node planetary gear set. The drive train may be operated at a first mechanical point when the first electric machine is operated at a substantially zero speed, and the drive train may be operated at a second mechanical point when the second electric machine is operated at a substantially zero speed, in one or more examples. Operation at either the first mechanical point or the second mechanical point may be achieved without clutches or hydro-mechanical devices.

  • Patent number: 11884161
    Abstract: Methods and systems are provided for an electric drive train of a vehicle. In one example, a method may include operating a first motor of a set of motors in a torque control mode at a first speed while operating a second motor of the set of motors in a speed control mode at a second speed. The second speed may be determined based on the first speed and torque may be summed at an output node of a planetary gear set coupled to each of the set of motors.
