METHOD OF CONTROLLING A HYBRID POWERTRAIN WITH MULTIPLE ELECTRIC MOTORS TO REDUCE ELECTRICAL POWER LOSSES AND HYBRID POWERTRAIN CONFIGURED FOR SAME

摘要

A method includes determining a first electrical power loss value of operating first and second electric machines with power inverters of both electric machines in an active mode. The method includes determining at least one of a second and a third electrical power loss value. The second electrical power loss value is with operating with the power inverter of the first electric machine in the active mode and the power inverter of the second electric machine in a standby mode. The third electrical power loss value is with operating with the power inverter of the second electric machine in the active mode and the power inverter of the first electric machine in the standby mode. A controller sets the power inverters in the respective modes corresponding with a lowest of the electrical power loss values.
