Abstract:
1. A control architecture for a vehicle comprising a multi-mode powertrain system including an internal combustion engine mechanically coupled to a single input member of a passive transmission having a single output member, the architecture comprising: a primary drive wheel, exclusively driven via a mechanical coupling to the single output member; a first non-combustion torque machine mechanically coupled to one of the internal combustion engine, the single input member, and the single output member; a secondary drive wheel exclusively driven via a mechanical coupling to a second non-combustion torque machine; an engine controller operatively connected to the internal combustion engine, including a control routine for determining and executing engine torque commands responsive to a hybrid engine torque command, and a control routine for determining a propulsion axle torque command responsive to an output torque request; a transmission controller operatively connected to the passive transmission, including a control routine for selecting and effecting operation of the passive transmission in a preferred gear responsive to the output torque request; and a hybrid controller operatively connected to the non-combustion torque machines, including
