Akira Eiraku, Sunto-Gun JP

Patent application numberDescriptionPublished
20080201034INTERNAL COMBUSTION ENGINE CONTROL APPARATUS AND METHOD - An internal combustion engine control apparatus includes: a fuel injector; a cooling fan of a radiator that radiates the heat of coolant in a coolant passage in the internal combustion engine; a flow rate control mechanism that variably controls the flow rate of the coolant; an abnormality detector that detects an abnormality of the cooling fan; and a controller that controls the amount of fuel injected from the fuel injector to the internal combustion engine and the operation of the flow rate control mechanism in accordance with the result of the abnormality detector.08-21-2008
20090259386Apparatus for and Method of Controlling Internal Combustion Engine Equipped With Turbocharger - A compressor flow rate is calculated using a compressor model, which is the physical model of a compressor. A plurality of the compressor models are provided, and the compressor model used for calculating the compressor flow rate is changed in accordance with an operational condition of an internal combustion engine.10-15-2009

Patent application numberDescriptionPublished
20090250037Control system and control method for internal combustion engine - A control system for an internal combustion engine calculates a provisional target value of the throttle opening in accordance with an accelerator pedal travel, upon detection of a sudden operation of the accelerator pedal. The system also calculates a target pressure change in the surge tank according to the provisional target value, on the basis of the actual surge tank pressure and the cylinder intake mass airflow, using a virtual intake system model. The control system sets a target throttle opening in accordance with the surge tank pressure and the cylinder intake mass airflow, so as to provide the target pressure change under a condition of the actual surge tank volume.10-08-2009
