PROBLEM TO BE SOLVED: To provide a break system capable of suppressing deficiency in controlling force by parking brake.SOLUTION: A parking brake controlling apparatus 21 set a target electric current value Amax previously stored for driving an electric actuator 43 or a corrected target electric current value A1 in which the target electric current value Amax is corrected based on fluid pressure information supplied to a disk brake 31 as an electric current threshold IM so as to be shifted to control holding mode as a response to parking brake request signal, and drives the electric actuator 43 until the electric current value flowing to the electric actuator 43 reaches the electric current threshold IM. The parking brake controlling apparatus 21 sets the target electric current value Amax as the electric current threshold IM and drives electric actuator 43 in a case where road gradient G of a gradient sensor 19 detecting gradient of road where a vehicle is parked is larger than a corrected working road gradient Gmin with which vehicular control may be maintained at a corrected target electric current value A1 (=Amin) to be a minimum value for correction based on the fluid pressure.SELECTED DRAWING: Figure 4

    【課題】駐車ブレーキによる制動力の不足を抑制することができるブレーキシステムを提供する。【解決手段】駐車ブレーキ制御装置21は、駐車ブレーキ要求信号に応じて制動保持状態となるように電動アクチュエータ43を駆動するために予め記憶された目標電流値Amax、または、ディスクブレーキ31に供給される液圧情報に応じて目標電流値Amaxを補正して補正目標電流値A1を電流閾値IMとして設定し、電動アクチュエータ43に流れる電流値が電流閾値IMとなるまで電動アクチュエータ43を駆動する。駐車ブレーキ制御装置21は、車両が停車している路面の勾配を検出する勾配センサ19の路面勾配Gが、液圧に応じて補正の最小値となる補正目標電流値A1(=Amin)で車両の制動を保持できる補正実施路面勾配Gminよりも大きいときに、目標電流値Amaxを電流閾値IMに設定して電動アクチュエータ43を駆動する。【選択図】図4
