Patent ID: 8195370

Claim:
A powertrain control system for a vehicle, comprising: 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; an axle-to-propulsion torque conversion module that converts the net axle torque request into a first propulsion torque request based on an axle gear ratio, a tire diameter, a transmission gear ratio, and a torque converter gain; a plurality of propulsion torque request modules that generate respective propulsion torque requests based on respective performance criteria of an engine of the vehicle; a propulsion torque arbitration module that determines a net engine torque request based on the first propulsion 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.
