<p><P>PROBLEM TO BE SOLVED: To efficiently distribute cores according to an arithmetic operation load of an internal combustion engine, in the internal combustion engine using a multi-core processor having a plurality of cores for arithmetic operation. <P>SOLUTION: This control device of the internal combustion engine 2 arithmetically operates a control target value of an actuator by using the control device 4 with a plurality of cores 6 mounted thereon. The control device 4 includes a core 6A associated with a first crank angle for every 30°CA, and a core 6B associated with a second crank angle equally dividing a part between the adjacent first crank angles by 10°CA. An arithmetic operation program for arithmetically operating the control target value by using a state quantity of the internal combustion engine in the associated crank angle, is allocated to the core 6A and the core 6B. The core 6B arithmetically operates the control target value by the arithmetic operation program when an engine rotating speed is abruptly changed, and is programmed to suspend an arithmetic operation of the control target value except in the sudden change. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
