PROBLEM TO BE SOLVED: To provide a brake force control device which can suppress a variation of a regeneration brake force even in a situation that a brake pedal is operated at deceleration at which the regeneration brake force corresponding to an operation amount of an accelerator pedal is generated, and a brake force control method.SOLUTION: A first requirement brake force calculation part 34 calculates an operation amount of an accelerator pedal AP within a brake range, and a first regeneration brake force corresponding to a traveling speed of a vehicle, a second requirement brake force calculation part 42 calculates an operation amount of a brake pedal BP, and a second regeneration brake force corresponding to the travel speed of the vehicle, and when the operation amount of the accelerator pedal AP is within the brake range, and the brake pedal BP is operated, a regeneration brake force control part 36 makes a drive motor DM generate a larger regeneration brake force out of the first regeneration brake force and the second regeneration brake force.SELECTED DRAWING: Figure 1
【課題】アクセルペダルの操作量に応じた回生制動力が発生している減速時にブレーキペダルが操作された状況であっても、回生制動力の変動を抑制することが可能な、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】第一要求制動力算出部34が、制動範囲内のアクセルペダルAPの操作量と車両の走行速度に対応した第一の回生制動力を算出し、第二要求制動力算出部42が、ブレーキペダルBPの操作量と車両の走行速度に対応した第二の回生制動力を算出し、回生制動力制御部36が、アクセルペダルAPの操作量が制動範囲内であり、且つブレーキペダルBPが操作されている場合、第一の回生制動力と第二の回生制動力のうち大きい回生制動力を、駆動用モータDMに発生させる。【選択図】図1
