To make both increase in regenerative energy and avoidance of quick locking of a wheel compatible, in executing DAC using a regenerative cooperation brake system in which a four-wheel isobaric hydraulic brake is combined with a front wheel regenerative brake.SOLUTION: A brake ECU calculates regenerative allowable braking force Freglim on the basis of an equal deceleration line Lgmax that can generate maximum deceleration, an ideal allocation line Lriso2 of a descendent slope road and an actual braking force allocation line Loil. The brake ECU generates only regenerative braking force if descendent slope-required braking force F* is equal to or below the regenerative allowable braking force Freglim, and generates the regenerative allowable braking force Freglim using a regenerative brake and causes a hydraulic brake device to generate braking force corresponding to shortages (F*-Freglim) of the regenerative allowable braking force Freglim with respect to the descendent slope-required braking force F*, if the descendent slope-required braking force F* exceeds the regenerative allowable braking force Freglim.SELECTED DRAWING: Figure 9

    【課題】 4輪等圧油圧ブレーキと、前輪回生ブレーキとを併用した回生協調ブレーキシステムにてDACを実施する場合に、回生エネルギーの増大と、車輪の早期ロックの回避とを両立させる。【解決手段】 ブレーキECUは、最大減速度を発生させることができる等減速度線Lgmaxと、降坂路の理想配分線Lriso2と、実制動力配分線Loilとに基づいて回生許容制動力Freglimを演算する。ブレーキECUは、降坂必要制動力F*が回生許容制動力Freglim以下である場合、回生制動力のみを発生させ、降坂必要制動力F*が回生許容制動力Freglimを超える場合には、回生ブレーキによって回生許容制動力Freglimを発生させるとともに、降坂必要制動力F*に対して回生許容制動力Freglimだけでは不足する分(F*−Freglim)の制動力を油圧ブレーキ装置で発生させる。【選択図】 図9
