PURPOSE: To improve comfortableness when a vehicle is tuned by making compensation for every steering handwheel speed and every steering angle error, and changing a fluid flow according to the steering handwheel speed and steering angle error. CONSTITUTION: This full hydraulic steering system 1 force-feeds an operating fluid to a steering control device 4 from a tank 3 through a pump junction P with a pump 2 then returns it to the tank 3 through a tank junction T. The steering control device 4 is connected to a handle 5 and is connected to two operating chambers 9, 10 of a steering motor 8 via two operating lines R, L. A processing device 13 makes compensation for a steering angle error, i. e., inconsistency between the position of the steering motor 8 and the position of the handle 5, together with a valve device 14. Compensation is made for every steering handwheel speed and every steering angle error, and a fluid flow is changed according to the steering handwheel speed and steering angle error. |
