PROBLEM TO BE SOLVED: To provide a vehicular brake system capable of improving power economy and fuel economy of a vehicle, when reduction of regenerative brake force is started when vehicle speed becomes low and then the regenerative brake force is finally stopped.SOLUTION: A regenerative brake reduction control part of a controller starts gradual reduction of regenerative brake force, so that, when a vehicle speed is reduced to first vehicle speed S1 during execution of a regenerative brake, the regenerative brake force is reduced compared to that before the reduction of the vehicle speed. The reduction of the regenerative braking force is performed by gradually reducing an upper limit value CM (upper limit value CMb) of the regenerative brake force, during a period until the vehicle speed becomes second vehicle speed S2 from the first vehicle speed S1.SELECTED DRAWING: Figure 3
【課題】車速が低くなると回生制動力の低減を開始して最終的に停止する場合に、車両の電費や燃費を向上させることができる車両の制動システムを提供する。【解決手段】制御装置の回生制動低減制御部は、回生制動の実行中に、車速が第1車速S1まで低下したときには、当該低下前より回生制動力が低下するように当該回生制動力の漸次の低減を開始する。これは、車速が第1車速S1から第2車速S2になるまでの間、回生制動力の上限値CMを漸次低減(上限値CMb)させることにより行う。【選択図】図3
