Abstract
A control system and method for controlling a hybrid electric vehicle powertrain with mechanical and electro-mechanical power sources that use an intelligent controller adapted to reduce driveline oscillations while minimizing hybrid vehicle battery limit violations. Damping of driveline torque oscillations is accomplished and violations of battery power limits are avoided by filtering estimated engine power.
