To provide a brake drive force control device which can perform exact control capable of coping with a change of a characteristic of a drive unit while stabilizing the control.SOLUTION: A brake drive force control device comprises a target brake drive force calculation part for calculating a target brake drive force on the basis of an acceleration requirement value, and a brake drive force distribution part for making the drive unit generate a brake drive force, and making a drive unit generate a brake drive force on the basis of the target brake drive force and availability indicating a range of the brake drive force which can be currently generated by the drive unit. The brake drive force distribution part makes the drive unit generate the target brake drive force when the target brake drive force is within the availability, makes the drive unit generate the brake drive force equivalent to a lower limit value of the availability when the target brake drive force is smaller than the lower limit value of the availability, then, performs calculation processing for suppressing a temporal change to the lower limit value of the availability, and makes the brake device generate the brake force equivalent to a difference between the lower limit value of the availability and the target brake drive force after the execution of the calculation processing.SELECTED DRAWING: Figure 1

    【課題】制御の安定化を図りつつ、駆動装置の特性変化に対応でき正確な制御を実現できる、制駆動力制御装置を提供する。【解決手段】制駆動力制御装置は、加速度の要求値に基づいて目標制駆動力を算出する目標制駆動力算出部と、目標制駆動力と駆動装置が現在発生可能な制駆動力の範囲を表すアベイラビリティとに基づいて、駆動装置に制駆動力を発生させ、制動装置に制動力を発生させる制駆動力配分部とを備え、制駆動力配分部は、目標制駆動力がアベイラビリティ以内である場合は、駆動装置に、目標制駆動力を発生させ、目標制駆動力がアベイラビリティの下限値未満である場合は、駆動装置に、アベイラビリティの下限値に相当する制駆動力を発生させ、アベイラビリティの下限値に時間変動を抑制する演算処理を行い、制動装置に、演算処理後のアベイラビリティの下限値と目標制駆動力との差分に相当する制動力を発生させる。【選択図】図1
