A method is provided for creating custom control software for a particular propulsion system configuration. Generic control software is provided that is configurable for use with a plurality of different propulsion system configurations. The generic control software is generically designed to control each of the different propulsion systems regardless of their different propulsion system configurations. The generic control software comprises a plurality of programmable arrays (or configuration tables). Information that characterizes a particular propulsion system configuration of the plurality of different propulsion system configurations is input into the programmable arrays to configure the generic control software into custom control software that is customized for use and designed to operate with the particular propulsion system configuration. The generic control software is configured into the custom control software that is applicable to and customized for use with the particular propulsion system configuration only after being programmed with the information that characterizes the particular propulsion system configuration.

An exemplary method for controlling torque at one or more wheels of a vehicle, including controlling both positive torque (acceleration) and negative torque (braking) with a single torque command. According to one embodiment, the method interprets the acceleration and braking intent of the driver, takes into consideration certain special conditions (e.g., vehicle dynamic conditions like wheel slip, over- and under-steer, etc.), and generates one or more individual torque commands that are sent to individual wheels or corners of the vehicle. The individual torque commands may address certain chassis and powertrain functions like acceleration and braking, and may provide full-feature torque control (i.e., acceleration, braking, vehicle dynamics, etc.) on an individual wheel basis. It is also possible for the method to be used in a system where a number of the common chassis, powertrain and/or vehicle dynamic modules have been integrated into a single torque control module or the like.
