Classification: CPC F  G | IPC F

Claim 0:
1. An internal-combustion-engine control apparatus comprising:
an intake-air physical quantity measurement apparatus having
a hot-film mass flow sensor that detects a flow rate of intake air to be sucked into an internal combustion engine and then outputs an intake-air flow rate detection signal, and
a thin-film temperature sensor that detects a temperature of the intake air and then outputs an intake-air temperature detection signal; and
a first-order advance compensator that applies advance compensation to the intake-air temperature detection signal by use of the intake-air temperature detection signal,

an intake-air-temperature correction control apparatus having
a memory storing instructions; and
at least one hardware processor configured to execute the instructions to implement:
calculating a time constant for performing the advance compensation and then inputting the time constant to the first-order advance compensator,
applying delay compensation to a calculation value of the first-order advance compensator, and outputting an output as a corrected intake-air temperature detection signal,
setting a first time constant, based on the intake-air flow rate detection signal,
setting a second time constant, based on the intake-air flow rate detection signal, and
selecting any one of the first time constant and the second time constant, and

wherein the first-order advance compensator applies advance compensation to the intake-air temperature detection signal, based on said selected time constant, and controls the internal combustion engine by use of the corrected intake-air temperature detection signal.
