1. An internal combustion engine control device comprising a control unit that controls an operating condition of an internal combustion engine of a vehicle equipped with the internal combustion engine and a temperature sensor that detects temperature information of the internal combustion engine, by using a temperature of the internal combustion engine calculated based on the temperature information,wherein the control unit controls the operating condition of the internal combustion engine based on a first temperature and a second temperature,wherein the first temperature is calculated based on temperature information detected by a first temperature sensor element attached to the internal combustion engine so as to be exposed to a combustion chamber, via a recess that is depressed from an inner wall surface of a wall defining the combustion chamber of the internal combustion engine, and opens to the inner wall surface, with the first temperature sensor being accommodated in a case of the temperature sensor, as a structural element of the temperature sensor,and wherein the second temperature is calculated based on temperature information detected by a second temperature sensor element disposed on a side of an outer wall surface of the wall than the first sensor element in a hole axial direction of a through hole penetrating the wall into which the case is inserted toward the recess, with the second temperature sensor being accommodated in the case to be shared by the first temperature sensor and the second temperature sensor, as a structural element of the temperature sensor.
