Abstract
A powertrain includes an engine, a transmission, and one or more accessories, such as an alternator or an air conditioning compressor, all operating based on commands from a controller. The controller is programmed to coordinate commands to the transmission with commands to the accessories to mitigate the impacts of transmission state changes. The accessory drive torque may be adjusted to compensate for the torque required to change the speed of a transmission internal shaft. The accessory effective inertia may be adjusted to maintain a powertrain natural frequency so that active damping can be maintained throughout a transmission state change event.
