Abstract:
A steering control apparatus, comprising:a steering shaft to which a steering wheel is mounted and on which the steering wheel exerts a steering effort;steering angle detecting means for detecting an angle of rotation of said steering shaft;turning means for turning a steered wheel, said turning means being mechanically separated from said steering shaft;target control amount calculating means for calculating a target control amount as a target of turning control, based on a detection result of said steering angle detection means;turning control means for outputting a turning control signal according to said target control amount to said turning means and controlling drive of said turning means so that a turning amount of said steered wheel becomes said target control amount; andcorrection means for correcting said turning control signal outputted, based on a running status of a vehicle;wherein said turning control means calculates a control displacement amount Ms defined by the following equation:Ms=Gs.times.(.theta.-bX)where .theta. is said target control amount, bX is said turning amount, and Gs is a turning gain coefficient, and said turning control means outputs information including this control displacement amount Ms as the turning control signal, and said turning means turns the steered wheel according to said control displacement amount Ms obtained from said turning control means.
