PROBLEM TO BE SOLVED: To provide a steering control system capable of reducing a possibility that an oscillation may occur.SOLUTION: A command current selection unit 60 includes: a correction coefficient designation block 60A that designated a correction coefficient K3 on the basis of a reaction force command current (normal reaction force T0) fed from an SBW reaction force command current arithmetic unit 54, an edge knock reaction force current (edge knock reaction force T4) fed from an edge knock reaction force current arithmetic unit, and an actual turning angle &thetas;t; a multiplier 60B that multiplies the normal reaction force T0 by the correction coefficient K3 so as to correct the normal reaction force T0; and a high selector 60C that compares the corrected normal reaction force T0 with the edge knock reaction force T4, and selects a larger reaction force as a final steering reaction force. The correction coefficient designation block 60A compares the orientation of the normal reaction force T0 with the orientation of the edge knock reaction force T4. If the orientation of the normal reaction force T0 is reverse to the orientation of the edge knock reaction force T4, the correction coefficient designation block 60A designates the correction coefficient K3, which is used to decrease or correct the normal reaction force T0, on the basis of the actual turning angle &thetas;t at that time. |
