PROBLEM TO BE SOLVED: To provide a vehicular steering control apparatus capable of limiting a driver from feeling discomfort in steering when suppressing vibration in a longitudinal direction of vehicle.SOLUTION: A vehicular steering control apparatus, incorporated in a vehicle that has motors disposed in left and right steering wheels for providing the left and right steering wheels with respective drive force, includes: detection means for detecting a vibration state of a vehicle in its longitudinal direction; drive force computation means for computing drive force of the motors for suppressing a vibration state of the vehicle in its longitudinal direction detected by the detection means; estimation means for estimating steering system torque generated in steering the steering wheels with the drive force computed by the drive force computation means; steering assist torque computation means for computing, as steering assist torque, torque required to cancel the steering system torque computed by the estimation means; and steering force assist means for assist with steering force on the basis of basic steering assist torque and the steering assist torque computed by the steering assist torque computation means.SELECTED DRAWING: Figure 1

    【課題】車両前後方向の振動を抑制する際に操舵に対して運転者が違和感を持つことを抑制可能な車両用操舵制御装置を提供すること。【解決手段】車両用操舵制御装置は、左右の転舵輪に設けられ、左右の転舵輪に対して独立して駆動力を付与可能な電動機を備える車両に設けられる車両用操舵制御装置であって、車両の前後方向の振動状態を検出する検出手段と、検出手段によって検出された車両の前後方向の振動状態を抑制するための電動機の駆動力を演算する駆動力演算手段と、駆動力演算手段によって演算された駆動力により転舵輪を駆動した際に生じる操舵系トルクを推定する推定手段と、推定手段によって推定された操舵系トルクを打ち消すために必要なトルクを操舵補助トルクとして演算する操舵補助トルク演算手段と、基本操舵補助トルクと操舵補助トルク演算手段によって演算された操舵補助トルクとに基づいて操舵力を補助する操舵力補助手段と、を備える。【選択図】図1
