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;
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.

Abstract
A hybrid system includes a transmission control module, a power source, a transmission, and a drive train. The transmission control module partially operates the hybrid system and receives operating information from various components of the system, calculates power losses in the drive train, and calculates the driving torque needed to reach a target power profile determined from a driver'"'"'s input.
