<P>PROBLEM TO BE SOLVED: To provide an inductive load drive control device and an inductive load drive control method capable of matching a start position of a dither control target current value after changing a target current value. <P>SOLUTION: An inductive load drive control device has: drive control means 12 that carries out the drive control of an inductive load 15 by PWM(Pulse-Width Modulation) control so that a current flowing in the inductive load 15 approaches to a target current value; target value control means 11 that adds a current control amount with a predetermined amplitude that has a cycle longer than that of the PWM control to a set current value to generate the target current value; and current control amount addition control means 37 that starts the addition of the current control amount from a specific phase state of the current control amount when the set current value changes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
