Powertrain Torque Management

Powertrain Torque Management is a control scheme to optimize engine torque and speed within the design contraints of the transmission and driveline. The strategy allows usage of high performance engines in today's vehicles without a corresponding increase in transmission/drivetrain size and torque capacity combined with potential improvements in durability, pleaseability, and performance. The purpose of this paper is to outline the development and implementation of such a strategy in conjunction with a family of V-6 engines being designed by the Buick, Oldsmobile, Cadillac Group (BOC) of General Motors Corporation.
