PROBLEM TO BE SOLVED: To provide a steering control device capable of controlling a rear wheel steering angle according to an actual operation of a steering wheel during emergency avoidance.SOLUTION: A steering control device 3 includes: an emergency avoidance state determination section 35 which determines whether a state is an emergency avoidance state for requiring emergency avoidance steering to avoid an obstacle on a route of a vehicle 100; and a rear wheel steering control section 36 which controls a rear wheel steering angle of the vehicle 100 on the basis of a steering operation of a driver and the determination result of the emergency avoidance state determination section 35. In the emergency avoidance state, the rear wheel steering control section 36 controls a rear wheel steering angle δr in either the same phase direction or the reverse phase direction according to quickness of the steering operation with respect to a front wheel steering angle δf of the vehicle 100 to be steered by the steering operation.SELECTED DRAWING: Figure 1
【課題】緊急回避時における実際のステアリングホイールの操作に応じた後輪舵角の制御が可能な操舵制御装置を提供すること。【解決手段】操舵制御装置3は、車両100の進路上における障害物を回避するための緊急回避操舵を必要とする緊急回避状態であるか否かを判定する緊急回避状態判定部35と、運転者のステアリング操舵及び緊急回避状態判定部35の判定結果に基づき、車両100の後輪舵角の制御を行う後輪操舵制御部36と、を備える。後輪操舵制御部36は、緊急回避状態であるとき、ステアリング操舵により操舵される車両100の前輪舵角δfに対して、ステアリング操舵の緩急に応じて、後輪舵角δrを同相方向あるいは逆相方向のいずれか一方に制御する。【選択図】図1
