Abstract:
A steering control apparatus comprising:a steering shaft on which a steering effort is exerted through a steering wheel;steering angle detecting means for detecting a steering angle which is an angle of rotation of said steering shaft;steering shaft driving means for rotating said steering shaft;steering effort detecting means for detecting the steering effort exerted on said steering shaft through said steering wheel;turning means for turning a steered wheel, based on said steering angle, said turning means being mechanically separated from said steering shaft;turning reaction force detecting means for detecting a turning reaction force exerted on said steered wheel;turning amount detecting means for detecting a turning amount of said steered wheel; andcontrol means for determining a steering control signal indicative of a steering shaft rotation control amount at least based on a first value equal to a deviation between a force proportional to the steering effort and the turning reaction force and a second value equal to a deviation between a target control amount based on the steering angle and the turning amount and for applying the steering control signal to the steering shaft driving means to rotate the steering wheel with a steering reaction force.
