Abstract:
1. A steering control apparatus for a vehicle having steering means for controlling steering torque applied to a steering wheel of said vehicle, braking means for controlling longitudinal force applied to each wheel of said vehicle, individually, and control means for performing at least one of an anti-skid control and a traction control by said braking means, comprising: longitudinal force difference calculation means for calculating a difference of the longitudinal force applied to right and left wheels of said vehicle in the lateral direction thereof; turning state amount detection means for detecting a turning state amount of said vehicle; desired state amount calculation means for calculating a desired amount of turning state of said vehicle; and deviation calculation means for calculating a turning state amount deviation between the turning state amount detected by said turning state amount detection means and the desired amount of turning state calculated by said desired state amount calculation means, wherein said steering means controls the steering torque on the basis of the difference of the longitudinal force calculated by said longitudinal force difference calculation means, and the turning state amount deviation calculated by said deviation calculation means, and wherein said desired state amount calculation means observes whether said control means is performing the control on a split road surface with different coefficients of friction being provided at the right and left side of said vehicle, and wherein said desired state amount calculation means calculates the desired amount of turning state, on the basis of the turning state of said vehicle obtained when one of the anti-skid control and the traction control is performed on the split road surface.
