Abstract
Techniques are disclosed herein that provide for controlling torque in a vehicle. In some embodiments, desired torque values are generated and are compared to an amount of torque currently being generated by an engine. If a different amount of torque is desired, an engine speed target is altered in a linear fashion, and then converted back to a torque request to be provided to an engine ECU for implementation. Techniques disclosed herein may cause changes in torque demand to be limited in such a way to cause predictable and smooth changes in engine speed, even when engine speed and torque do not have a linear relationship to each other.
