Abstract
An automatic steering center setting apparatus provided in a power steering system for a vehicle comprises a static steering motion detecting circuit for detecting a static steering motion state in response to a steering angle position signal which is obtained through a steering angle sensor and then a steering angle detecting circuit and for outputting a static steering center instruction signal; a dynamic steering motion detecting circuit for detecting a dynamic steering motion state and for outputting a dynamic steering center instruction signal; and a steering center setting circuit for setting a steering center and starting the function of a steering angle responsive characteristic when a current steering angle position signal coincides with the static or dynamic steering center instruction signal.
