Abstract
A torque request generation system for use with a coordinated torque control system of a vehicle includes an input receiving a vehicle speed and an axle torque command. A datastore records a three-dimensional torque surface defined in terms of a coordinate system having a first axis related to the axle torque command, a second axis related to the vehicle speed, and a third axis related to an axle torque request. A torque request generation module accesses the datastore and generates a torque request based on a correlation between the axle torque command and the vehicle speed respective of the three-dimensional torque surface.
