Association of torque requesting modules in a coordinated torque architecture

Abstract

The invention relates to an association of torque requesting modules in a coordinated torque architecture. The powertrain control system for a vehicle includes a plurality of axle torque request modules that generate respective axle torque requests based on respective performance criteria of a vehicle, an axle torque arbitration module that generates a net axle torque request based on the plurality of axle torque requests, a plurality of propulsion torque request modules that generate respective propulsion torque requests based on respective performance criteria of an engine of the vehicle, apropulsion torque arbitration module that determines a net engine torque request based on the net axle torque request and the plurality of propulsion torque requests, and a propulsion torque control module that controls a plurality of actuators based on the net engine torque request such that the engine produces an output torque in accordance with the net engine torque request.
