Abstract: A system according to the principles of the present disclosure includes a desired capacity module, an anticipated torque request module, and an engine actuator module. The desired capacity module generates a desired torque capacity of an engine at a future time based on a present torque request and a maximum torque output of the engine. The anticipated torque request module generates an anticipated torque request based on the desired torque capacity. The engine actuator module controls an actuator of the engine at a present time based on the anticipated torque request.

Abstract: A method for operating a multi-mode powertrain system includes monitoring an operator request for tractive power, and arbitrating the operator request for tractive power with axle torque constraints and crankshaft torque constraints. An immediate tractive torque request and a predicted tractive torque request are determined based upon the arbitrated operator request for tractive power. The predicted tractive torque request is shaped based upon driveability torque constraints. Operation of torque-generative devices of the multi-mode powertrain system are controlled based upon the predicted tractive torque request and the driveability-shaped predicted tractive torque request.
