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, and submit a torque request to the prime mover that is based upon a desired output torque divided by the torque phase ratio.
Claims20
A vehicle comprising:
- a prime mover operable for generating an input torque on an input shaft;
- 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;
- and
- a controller in communication with the transmission and the prime mover, wherein the controller is programmed to:
- generate a torque phase ratio;
- and
- submit a torque request to the prime mover that is based upon a desired output torque divided by the torque phase ratio.
