To provide a brake force control device capable of realizing suitable riding comfort and operation feeling in a coasting state of a vehicle.SOLUTION: A brake force control device generates negative target driving force by using a plurality of actuators in a coasting state. The brake force control device detects a disabled state in which a part of the actuators temporarily cannot generate negative driving force, and an estimation state when the disabled state in near future is estimated. The drive force control device gradually increases the negative driving force generated by the actuator every time when the coasting state occurs before the disabled state is established when the estimation state is established, so that the actuator does not generate driving force even when the coasting state occurs in the disabled state, and the negative driving force generated by the actuator is gradually decreased to the target driving force every time when the coasting state occurs after the disabled state.SELECTED DRAWING: Figure 2

    【課題】車両の惰行状態において好適な乗り心地や操作感を実現できる制動力制御装置を提供する。【解決手段】制動力制御装置は、惰行状態において、複数のアクチュエータを用いて負の目標駆動力を発生させる。制動力制御装置は、一部のアクチュエータが負の駆動力を一時的に発生させることができなくなる不可状態と、近い将来に不可状態となることが予測される予測状態を検出する。制動力制御装置は、予測状態が成立すると不可状態が成立する前において、惰行状態が発生するたび、そのアクチュエータに発生させる負の駆動力を徐々に大きくし、不可状態において、惰行状態が発生しても、そのアクチュエータに駆動力を発生させず、不可状態の後において、惰行状態が発生するたび、そのアクチュエータに発生させる負の駆動力を目標駆動力まで徐々に小さくする。【選択図】図2
