The simultaneous demand for improvements to performance, drivability, emissions, and fuel economy are driving increasingly complex automotive powertrain solutions. New controls strategies are required to effectively manage and fully utilize the opportunities presented by these new powertrains. This paper outlines the advance powertrain controls development work underway within DaimlerChrysler Corporation, in support of these requirements. A powertrain coordination strategy that translates the driver demand into the most effective combination of all powertrain elements is described. A common interface to the powertrain elements is proposed.
