Abstract
A system and method are provided for controlling an air handling system for an internal combustion engine including a turbocharger having a variable geometry turbine fluidly coupled to an exhaust manifold of the engine and a compressor fluidly coupled to an intake manifold of the engine, and an electric motor coupled to a rotatable shaft connected between the compressor and the variable geometry turbine. A target torque required to drive the compressor to achieve target compressor operating parameters is determined, a maximum available torque that can be supplied by the variable geometry turbine in response to a target exhaust gas flow through the variable geometry turbine is determined, and the electric motor is enabled to supply supplemental torque to the rotatable shaft if the target torque is greater than the maximum available torque.
