To provide a control device that secures real time performance of a control of an internal combustion engine.
An engine control device 1 includes: an AD conversion unit 31 which performs a first conversion processing for carrying out an AD conversion of a detected value by a water temperature sensor 41 or the like with a predetermined time period, and a second conversion processing for carrying out the AD conversion of a detected value by an in-cylinder pressure sensor 15 with a predetermined crank-angle period; an in-cylinder pressure estimation unit 32 which estimates the detected value by the in-cylinder pressure sensor 15 to obtain an estimated value of an in-cylinder pressure; and a control processing unit 34 which performs control based on the detected value by the water temperature sensor 41 or the like after the first conversion processing, and a control based on the detected value of the in-cylinder pressure or the estimated value of the in-cylinder pressure. When the timing of performing the first and second conversion processing overlaps, the AD conversion unit 31 does not perform the second conversion processing, and then the control processing unit 34 performs the control on the basis of the estimated value of the in-cylinder pressure.
