Abstract: A method of controlling an engine system, having both an electric driven compressor and an exhaust driven turbocharger for compressing a flow of combustion air for an internal combustion engine, includes defining a total pressure ratio target for the flow of combustion air, and defining a distribution factor to calculate a first portion of the total pressure ratio target and a second portion of the total pressure ratio target. The sum of the first portion of the total pressure ratio target and the second portion of the total pressure ratio target is equal to the total pressure ratio target. The electric driven compressor is controlled to provide the first portion of the total pressure ratio target, and the exhaust driven turbocharger is controlled to provide the second portion of the total pressure ratio target.
