<p><P>PROBLEM TO BE SOLVED: To stabilize the operation of an adjustable valve timing mechanism. <P>SOLUTION: The basic manipulated variable of the adjustable valve timing mechanism is calculated from the target angle and actual angle of the adjustable valve timing mechanism on the side of an intake valve, calculated in accordance with an engine speed and a load. An operation correcting amount is calculated corresponding to cam driving torque calculated in accordance with the lifting amount of the intake valve, changed by an adjustable valve lifting mechanism, and the engine speed. By correcting the basic manipulated variable with the operation correcting amount, the final manipulated variable of the adjustable valve timing mechanism is calculated to be output. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
