An engine system control apparatus includes a parameter reception unit that receives parameters necessary for acquiring a pressure ratio of the low-pressure compressor and a pressure ratio of the high-pressure compressor, a pressure ratio acquisition unit that acquires the pressure ratio of the low-pressure compressor and the pressure ratio of the high-pressure compressor based on the parameters, an inter-compressor pressure ratio acquisition unit that acquires an inter-compressor pressure ratio obtainable by dividing the pressure ratio of the high-pressure compressor by the pressure ratio of the low-pressure compressor, and a control unit that controls the exhaust gas flowrate adjustment unit such that the inter-compressor pressure ratio becomes a predetermined pressure ratio for optimizing an operation efficiency of the engine system.

Engine system control apparatus and engine system

A vehicle includes: a power source; a first drive device configured to be driven by an output of the power source; a second drive device configured to be driven by the output of the power source; a non-stage transmission device capable of continuously changing a rotation speed which is transmitted to an input shaft of the second drive device; a power distribution device coupled to an output shaft of the power source, coupled to an input shaft of the first drive device and an input shaft of the non-stage transmission device, and configured to be capable of distributing the output of the power source to the first drive device and the second drive device in a state where the output shaft of the power source is coupled to the input shaft of the first drive device and the input shaft of the non-stage transmission device at respective predetermined fixed reduction ratios; a first instruction device configured to output a first instruction value related to a rotation speed of the input shaft of the first drive device; a second instruction device configured to output a second instruction value related to a torque of the input shaft of the second drive device; and a control device configured to be capable of controlling the output of the power source and a transmission ratio of the non-stage transmission device. The control device includes: an output control part configured to control an output of the power source in accordance with the first instruction value outputted from the first instruction device; and a transmission control part configured to control the transmission ratio of the non-stage transmission device in accordance with the second instruction value outputted from the second instruction device.
