Abstract
A torque management system and method is described by which the torque provided by an engine can be controlled based on a mass of the vehicle and, if available, instantaneous and/or predictive slope information. Also, in some modes of operation, torque can be controlled based on speed limit information for upcoming road segments to be traveled by a vehicle. In addition to controlling the maximum allowable torque, optionally the minimum allowable torque can also be controlled to prevent inadvertent decelerations of the vehicle. A driver/operator can optionally override the torque control and the history of override requests can optionally be used to adjust overrides of the system. A plurality of torque control approach sub-methods can be made available with the appropriate sub-mode being selected depending, for example, upon the extent of the available information.
