摘要: For an energy-saving type control, a value of a control low rate QP controlled by a flow control valve V is closer to a value of a flow rate required by an output side such as a power cylinder 8, a steering valve 9 or the like, to suppress a driving torque of a pump P. An excitation current I of a solenoid SOL is specified on the basis of a solenoid current instruction value IT based on a steering torque and a solenoid current instruction value IS defining a standby flow rate.

摘要: Provision of a power steering system which is capable of preventing a delay in response for outputting a solenoid current instruction value SI. A controller C stores a table of basic current instruction values I1 corresponding to combinations of steering angles and steering angular velocities. The controller C obtains a basic current instruction value I1 from the table, and multiplies the obtained basic current instruction value I1 by a current instruction value I2 determined on the basis of a vehicle speed, and then determines the multiplied value as a solenoid current instruction value SI.
