<p>PROBLEM TO BE SOLVED: To provide the steering-device which prevents the occurrence of vibration when an operator lets go his hold of a steering wheel. SOLUTION: This invention is concerned with the steering system for an automobile, which is equipped with at least one wheel capable of being steered, an actuator 13, and with a duplicate mechanism, in which the super imposition of a steering actionδL by an operator and an action by the actuator thereby allows a steering actionδM by the wheel capable of being steered to be obtained, the actuator is driven at least by manipulated variable lid related with steering actions on the part of the operator, in that case, the aforesaid way is applied to the steering device the manipulated variable of which is restricted. A finite difference between restricted manipulated variable and manipulated variable is introduced through an integral block 58, so that the definite difference is thereby superimposed to the manipulated variable. As a result, the inclination of vibration is effectively reduced when the operator lets go his grip on to the steering wheel.</p> |
