SENSOR OUTPUT VALUE ESTIMATION DEVICE

摘要

The present invention pertains to a sensor output value estimation device that effectively estimates sensor output values reflecting a response delay of a temperature sensor. The sensor output value estimation device includes an estimated gas temperature calculation unit (43) for calculating an estimated gas temperature of an engine (10) on the basis of at least a running condition of the engine (10) and a state quantity of the gas in the engine (10). The sensor output value estimation device also includes an estimated sensor output value calculation unit (44) for calculating an estimated sensor output value reflecting the response delay of the temperature sensor (31) on the basis of the calculated estimated gas temperature and a pre-stored first model formula specifying the relation among the temperature change time constant of the temperature sensor (31), the gas flow rate, and the gas temperature.
