Zusammenfassung:A powertrain assembly includes a transmission, an engine, first and second motor/generators and a controller. The controller includes a processor and memory on which is recorded instructions for executing a method for controlling engine pulse torque cancellation commands. The controller is programmed to determine an engine pulse torque (TP). The controller is programmed to calculate a first motor torque pulse command (TA) for the first motor/generator as a product of a first gear factor (G1), the engine pulse torque (TP) and a first ratio (IA/IE) of a predetermined first moment of inertia (IA) for the first motor/generator and a predetermined engine moment of inertia (IE). Similarly, the controller is programmed to calculate a second motor torque pulse command (TB) for the second motor/generator. The controller is programmed to control the first and second motor/generators in response to the first and second motor torque pulse commands, respectively.
