PROBLEM TO BE SOLVED: To improve fuel economy by performing regeneration efficiently, without causing interruption of deceleration of a vehicle due to intervention of ABS control and making braking force unstable.SOLUTION: The vehicle braking force control device has a function of an ABS of controlling braking force during braking to prevent wheels respectively from being locked; calculates ABS intervention allowable degrees PABS existing before the respective ABSs are operated, on the basis of motion states of wheels to be controlled by the respective ABSs; compares the ABS intervention allowable degrees PABS existing before the respective ABSs are operated; decreases regeneration braking force acting on the wheels at slower speed as the wheels have larger ABS intervention allowable degrees PABS and increases hydraulic braking force, so as to switch a regeneration brake to a hydraulic brake.SELECTED DRAWING: Figure 2
【課題】ABSの介入で車両の減速度抜けが生じたり制動力が不安定になることなく、また、効率良く回生が行われ燃費を向上させる。【解決手段】制動中の制動力を制御して各輪毎に車輪のロック状態を防止するABSの機能を有し、各ABSが制御対象とする車輪の運動状態に基づいて各々のABSが作動するまでのABS介入余裕度PABSを算出し、各々のABSが作動するまでのABS介入余裕度PABSを比較して、ABS介入余裕度PABSが大きな車輪ほど緩やかな速度で該車輪に作用している回生ブレーキを低下させ、液圧ブレーキを増加させて回生ブレーキを液圧ブレーキにすり替える。【選択図】図2
