<p>A controller of an internal combustion engine, including an operation state monitoring unit (1-13, 50, 72) for outputting an operation state value representing the operation state of the internal combustion engine, and a control unit (71). The control unit includes an input circuit (116, 113, 119) that receives the operation state value from the operation state monitoring unit and outputs it as an operation state monitoring value, a reference power source circuit (70) for generating a reference voltage (Vcc) for operating a controller (Fig. 2) on the basis of a battery voltage from a battery (50), and a unit (CPU 100) for controlling the internal combustion engine on the basis of the operation state monitoring value from the input circuit. Correction data for correcting the error based on at least one of the error of the output of the input circuit and the error of the reference voltage from the reference power source circuit is determined in advance for each controller and is stored in a memory (112) in the control unit. The operation state monitoring value from the input circuit is corrected by the correction data to obtain a correct operation state monitoring value, and the internal combustion engine is controlled on the basis of the correct operation state monitoring value so obtained (CPU 100, Figs. 3 and 8, steps 508 to 514).</p> |
