The present invention addresses the problem of providing a braking force control device for a vehicle, which is capable of achieving both steering performance and quietness during low-speed steering of the vehicle. A behavior stabilization device (21) for a vehicle braking force control device (1) is provided with: a plurality of first valves (22a-22d) for controlling the movement of an operating fluid to each of a plurality of friction brakes (20a-20d); second valves (23a-23d) for controlling the movement of the working fluid to the reservoirs (25a-25b); and a drive motor (27) that drives the pumps (26a-26b), and the pumps (26a-26b) inject to a path leading from the reservoirs (25a-25b) to the hydraulic pressure generating device (12). A control device (50) that, when the vehicle (100) is in a turning state at a vehicle speed equal to or less than a prescribed vehicle speed, executes turning control for generating hydraulic pressure by means of the hydraulic pressure generation device (12) by controlling the operation of the electric actuator (33), and for applying a braking force to the plurality of wheels (110a-110d) by controlling the opening/closing state of the first valves (22a-22d) and the second valves (23a-23d); in the turning control, the drive of the drive motor 27 is stopped.
本发明要解决的问题是提供可以兼顾车辆的低速转弯时的转弯性能与安静性的车辆用制动力控制装置。本发明的车辆用制动力控制装置1的行为稳定化装置21具有:多个第一阀22a~22d,控制工作液向多个摩擦制动器20a~20d各者的移动;第二阀23a~23d,控制工作液向储液器25a~25b的移动;及驱动马达27,驱动泵26a~26b,泵26a~26b向从储液器25a~25b通往液压产生装置12的路径进行喷射。控制装置50,在车辆100以规定车速以下的车速处于转弯状态的情况下,执行转弯控制,转弯控制是控制电动致动器33的动作而利用液压产生装置12产生液压,并控制第一阀22a~22d及第二阀23a~23d的开闭状态从而对多个车轮110a~110d施加制动力;在转弯控制中,使驱动马达27的驱动处于停止状态。
