<P>PROBLEM TO BE SOLVED: To provide a power steering device restraining energy loss to the minimum by controlling a control flow rate QP in accordance with a travelling condition and a steering state of a vehicle. <P>SOLUTION: A controller computes or memorizes a solenoid electric current command value Iθ in accordance with a steering angle from a steering angle sensor and a solenoid electric current command value It in accordance with steering torque, respectively multiplies the solenoid electric current command value Iθ of a steering angle system and the solenoid electric current command value It of a steering torque system with solenoid electric current command values IV1, IV2 set based on velocity, compares these solenoid electric current command value of the steering angle system and solenoid electric current command value of the steering torque system with each other in size and makes the selected larger value of them a solenoid electric current command value I. <P>COPYRIGHT: (C)2004,JPO |
