Abstract: A control-module implemented method for controlling a powertrain system comprising an internal combustion engine, at least one electric machine, a high-voltage battery and an electro-mechanical transmission operative to transmit torque to a driveline includes monitoring a state of charge (SOC) of a high-voltage battery configured to provide stored electrical power to a first electric machine, a second electric machine and at least one auxiliary load. A trickle-charging event is enabled only when the SOC of the high-voltage battery is less than a first SOC threshold. The trickle-charging event activates the first clutch coupled to a first planetary gear set. The trickle-charging event further coordinates a torque capacity of the activated first clutch and a charging set of torque commands between the engine, the first electric machine and the second electric machine to establish a net zero output torque condition.

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.
