<p>PROBLEM TO BE SOLVED: To provide the optimum steering feeling corresponding to the road surface state by generating the weighting function, and providing a control means setting the target current signal for driving a motor in a feedback loop from the reaction torque output to a generalized plant. SOLUTION: This power steering device 1 is provided with a generalized plant 2 incorporating the control specification to be realized into the control object of a steering system for the desired modeling and weighting function generating means 4, 5, 6 independently weighting in separate systems respectively between the rack shaft input FR or handle input FH forming the input of the generalized plant 2 and the reaction torque TR output forming the output. A control means 7 setting the target current signal IMS driving a motor is provided in a feedback loop from the reaction torque TR output to the target current input of the generalized plant 2, the road surface information is accurately transferred to a driver, and the accurate assisting force corresponding to the handle input is generated.</p> |
