RANGE MAXIMIZATION OF A HYBRID VEHICLE OPERATING IN AN ELECTRIC VEHICLE OPERATING STATE
First Claim
1. A method for maximizing range capability of a vehicle while operating in an electric vehicle operating state, said vehicle including a powertrain including an engine and at least one electric machine, the method comprising:
- determining an incipient electric vehicle operating state of the powertrain;
setting a preferred charge/discharge rate of an electric energy storage device to a maximum charging rate; and
controlling the powertrain to an operating state including an engine state that is ON to effect charging the electrical energy storage device based on the maximum charging rate.

Abstract
A vehicle has a powertrain including an engine and at least one electric machine. A method for maximizing range capability of the vehicle while operating in an electric vehicle operating state includes determining an incipient electric vehicle operating state of the powertrain, setting a preferred charge/discharge rate of an electric energy storage device to a maximum charging rate, and controlling the powertrain to an operating state including an engine state that is ON to effect charging the electrical energy storage device based on the maximum charging rate.
