<P>PROBLEM TO BE SOLVED: To provide a power steering device to certainly control a necessary flow rate even when a pump assembly PA has an individual I-Q characteristic. <P>SOLUTION: A controller C is furnished with a correction commanding part 22 to correct a logical value computed by a computing part 21. This correction commanding part 22 memorizes a correction table 23 formed in accordance with a relative relation of a logical electric current command value TI and a logical control flow rate QP' and a relative relation of a control flow rate QP and a corrected electric current command value SI specified for each of real machines, and the correction commanding part 22 also specifies the corrected electric current command value SI from the logical electric current command value TI in accordance with the correction table 23, and controls an exciting electric current of a solenoid SOL of a variable orifice (a) in accordance with this corrected electric current command value SI. <P>COPYRIGHT: (C)2007,JPO&INPIT |
