<P>PROBLEM TO BE SOLVED: To provide an electric power steering control device which reduces time to update of a duty command value while reducing A/D starting interruption. <P>SOLUTION: A duty ratio is computed in accordance with an A/D converted analog signal by starting A/D conversion every plural cycle of a triangle wave and the duty command value is reflected to a motor driving electric current every cycle of the triangle wave. A time difference until the update of the duty command value is restrained to the minimum while reducing the A/D starting interruption, and stable motor control is made. <P>COPYRIGHT: (C)2007,JPO&INPIT |
