1. A method, comprising:

  • controlling a power source output power of a vehicle using a controller, wherein the vehicle has a drive train and a power source, and wherein the controller controls the power source and the drive train;

    determining a target drive train output power using the controller, wherein the target drive train output power is determined using a command input; and

    determining the power source output power using the controller, wherein the target drive train output power is derived from the power source output power; and

    wherein the controller determines the power source output power using one or more loss parameters and the target drive train output power;

    wherein the loss parameters include a kinetic power loss, and wherein the kinetic power loss is calculated as a function of rotational inertia loss parameters within the drive train; and

    wherein the loss parameters include a clutch power loss for a clutch, wherein the drive train has at least one clutch, wherein the clutch has a plurality of clutch plates, and wherein the clutch power loss is calculated as a function of clutch loss parameters.
