Claim Text:
1. A method of controlling a hybrid vehicle having a hybrid powertrain with an engine, a motor/generator, and an energy storage device that provides electrical energy to the motor/generator; the method comprising: receiving data indicative of anticipated future vehicle operating conditions, including an expected acceleration or deceleration event; calculating acceleration or deceleration associated with the expected acceleration or deceleration event for a given vehicle speed; calculating power demanded for the calculated acceleration or deceleration; calculating expected energy losses or expected regenerative power for each one of different functional operating modes of the powertrain for which motor/generator torque and power of the energy storage device would remain within predetermined limits for the power demanded; wherein said calculating is based at least partially on the data; updating a stored database of energy loss values and regenerative power values with said calculated expected energy losses or expected regenerative power; determining via a controller optimal operating parameters for the engine and for the motor/generator based at least partially on the data; wherein said determining optimal operating parameters based on the data is based at least partially on the calculated expected energy losses or expected regenerative power in the stored database; and commanding a powertrain operating strategy for the engine and the motor/generator based on the determined optimal operating parameters.
