Abstract
A control method and system for a hybrid electric vehicle powertrain is disclosed. A filtered, profiled battery power modifier is used in calculating a final desired wheel power. Unstable battery power oscillations are avoided when a change in driver power demand is made. The effect of engine torque disturbances also is avoided during steady state operation when desired battery power is between limiting charge or discharge values.
