Zusammenfassung:To provide a steering control device for a vehicle so as to make it easy for a driver to detect road surface information and shift to an avoidance operation when entering a low-μ-road.MEANS FOR SOLVING THE PROBLEM: A steering control device controls steering in a vehicle (1) having: a front wheel steering device (12) and a rear wheel steering device (13) each of which is capable of generating turning torque; and a reaction force device (14) attached to a handle (15) and capable of generating reaction force torque relative to the turning torque. The steering control device includes: a determination unit (10) that determines whether a friction coefficient μf of a road surface of a front wheel (2f) is smaller than a friction coefficient μr of a road surface of a rear wheel (2r); and a control unit (11) that, if it is determined that the friction coefficient μf is smaller than the friction coefficient μr, executes control so that the reaction force torque of the front wheel increases, the reaction force torque being distributed to the front wheel and the rear wheel.SELECTED DRAWING: Figure 1 【課題】車両の操舵制御装置において、低μ路に進入した際に、運転者が路面情報を感知して回避操作に移行することを容易ならしめる。【課題を解決するための手段】操舵制御装置は、転舵トルクを夫々発生可能な前輪転舵装置(12)及び後輪転舵装置(13)並びにハンドル(15)に付帯しており転舵トルクに対する反力トルクを発生可能な反力装置(14)を有する車両(1)において操舵を制御する。操舵制御装置は、前輪(2f)の路面の摩擦係数μfが後輪(2r)の路面の摩擦係数μrよりも小さいか否かを判定する判定部(10)と、小さいと判定された場合に、反力トルクにおける前輪及び後輪間の配分のうち前輪分を増加させるように制御する制御部(11)とを備える。【選択図】図1
