Abstract:
A method for controlling a hybrid powertrain includes the following steps: receiving a torque request; determining a plurality of possible motor torques for the first and second electric machines capable of achieving the torque requested; determining system power losses of the powertrain for all the possible motor torques for the first and second electric machines capable of achieving the torque requested; determining a lowest power loss of the system power losses determined for the plurality of possible motor torques for the first and second electric machines; determining a first operating torque for the first electric machine and a second operating torque for the second electric machine that correspond with the lowest power loss; and commanding the first electric machine to generate the first operating torque and the second electric machine to generate the second operating torque in order to achieve the torque requested while minimizing the system power losses.
