Abstract
A propulsion system controller for a vehicle that includes a prime mover operable for generating an input torque on an input shaft, and a transmission connected to the prime mover that is configured to receive the input torque from the input shaft and produce an output torque on an output shaft. The controller is programmed to generate a torque phase ratio, rationalize the generated torque phase ratio, and submit a torque request to the prime mover that is based upon a desired output torque divided by the rationalized torque phase ratio.
