PROBLEM TO BE SOLVED: To provide a braking-driving force control apparatus and a braking-driving force control method, which enable a driver to facilitate an operation for deceleration actively, the driver who has predicted the occurrence of an unstable behavior of a vehicle due to an increase in deceleration in the state of the grip performance of a wheel being undermined.SOLUTION: An apparatus or method performs: detecting an operation amount of a braking-driving force operator; decreasing a braking-force instruction value from a pre-set initial braking-force instruction value in response to an increase in a detected operation amount in a braking zone where the detected operation value is between an un-operated state and less than a given operation amount, or setting a driving-force instruction value in accordance with a difference between the given operation amount and the detected operation amount in a driving zone where the detected operation amount is equal to or more than the given operation amount; detecting a wheel grip value that is a value in accordance with grip performance of the wheel; and correcting, if the detected wheel grip value is less than a pre-set wheel grip threshold, the initial braking-force instruction value to be smaller in the braking zone as a difference between the wheel grip value and the wheel grip threshold increases.

    【課題】車輪のグリップ性能が低下した状態で減速度の増加により不安定な挙動が発生すると予測した運転者に対し、減速度の操作を能動的に行いやすくさせることが可能な、制駆動力制御装置及び制駆動力制御方法を提供する。【解決手段】制駆動力操作子の操作量を検出し、検出した操作量が未操作の状態から所定操作量未満である制動範囲では、検出した操作量の増加に応じて制動力指令値を予め設定した初期制動力指令値から減少させ、検出した操作量が所定操作量以上である駆動範囲では、所定操作量と検出した操作量との偏差に応じた駆動力指令値を設定し、車輪のグリップ性能に応じた値である車輪グリップ値を検出し、検出した車輪グリップ値が予め設定した車輪グリップ閾値未満となると、車輪グリップ値と車輪グリップ閾値との偏差が大きいほど、制動範囲で初期制動力指令値を小さく補正する。【選択図】図15
