摘要： In a hydraulic brake system including a cylinder device that includes a front chamber and a rear chamber located on front and rear sides of a pressurizing piston, respectively, presence or absence of liquid leakage from a brake line is detected based on a hydraulic pressure in the rear chamber. Where a state in which a subtraction value obtained by subtracting an actual rear hydraulic pressure from a target rear hydraulic pressure is larger than a first malfunction determination threshold value has continued for a time not shorter than a first malfunction determination time, and then an increase of the actual rear hydraulic pressure at a rate not lower than a set rate has caused the subtraction value to become smaller than a return determination threshold value, it is determined that the pressurizing piston has been bottomed due to liquid leakage from the front chamber.

摘要： When a brake ECU is started up rapidly by a brake pedal operation, the brake ECU executes a depression force fluid pressure mode. When the control pressure detected by a control pressure sensor becomes smaller than a switching determination threshold value, the brake ECU determines that an operation of returning a brake pedal is being performed, and switches the braking mode from the depression force fluid pressure mode to a normal control mode. Accordingly, even when the operation of a stroke simulator has been started, no uncomfortable feeling is given to a driver. Further, even when the operation of returning the brake pedal is not being performed, the braking mode is switched from the depression force fluid pressure mode to a simulator non-operation control fluid pressure mode when a vehicle starts to travel. Consequently, desired braking force can be rapidly generated.
摘要翻译：当通过制动踏板操作快速起动制动ECU时，制动ECU执行抑制力流体压力模式。当由控制压力传感器检测到的控制压力变得小于切换判定阈值时，制动ECU判断为正在执行返回制动踏板的动作，并且将制动模式从抑制力流体压力模式切换到正常控制模式。因此，即使在开始了行程模拟器的动作的情况下，也不会给驾驶员带来不舒服的感觉。此外，即使当没有执行返回制动踏板的操作时，当车辆开始行驶时，制动模式从踏力流体压力模式切换到模拟器非操作控制流体压力模式。因此，可以快速产生期望的制动力。

摘要： In a brake controlling device (20), a separating valve (60) is provided in a main flow path (45) for interconnecting a first liquid pressure circuit and a second liquid pressure circuit. When an abnormality detecting section detects an abnormality relating to brake fluid pressure, a controlling section sets the separating valve (60) to a closed state. A leakage suppressing section performs leakage suppressing processing for suppressing entry of a brake fluid, which is in the first liquid pressure circuit, into the second liquid pressure circuit after the separating valve (60) is set to the closed state. A leakage suppressing section sets a master cut valve (64) to a closed state to perform the leakage suppressing processing.

摘要： In a brake apparatus, an activation current for opening a simulator cut valve from a closed state is applied, whereupon a steady-state current is applied continuously to maintain the open state. A brake control apparatus and a brake control method are employed to perform control in which a valve opening current, which is higher than the steady-state current, is applied to the simulator cut valve every time a brake pedal is depressed. Thus, in a brake apparatus including a switch valve that is driven steadily by applying the steady-state current thereto, favorable control responsiveness can be maintained in the switch valve at all times while achieving a reduction in power consumption.

摘要： A brake control apparatus obtains a required braking force using a hydraulic braking force in combination with a regenerative braking force. The brake control apparatus includes a hydraulic brake unit that controls the hydraulic braking force. When the deviation of an actual hydraulic pressure from a target pressure falls outside a permissible range (d), the hydraulic brake unit controls the actual hydraulic pressure in such a manner that the deviation falls within the permissible range. On the other hand, when the deviation is within the permissible range (d), the hydraulic brake unit maintains the actual hydraulic pressure. The hydraulic brake unit includes a control unit that detects timing (Ta) at which usage of the hydraulic braking force needs to be started to compensate for a deficiency from the required braking force, and that raises (r) the target pressure at the detected timing (ta).

摘要： In a brake control apparatus that controls braking forces which are applied to wheels based on the pressure of the hydraulic fluid, when the pressure detected by a control pressure sensor (73) is equal to or higher than a predetermined value while a partition valve (60) is closed, a master cut valve (64) is closed to suppress an increase in the pressure in a first passage (45) in a first hydraulic circuit (37), to which the control pressure sensor (73) is connected. Alternatively, the control pressure sensor (73) is protected against overpressure by opening the outlet valve (56,57) or the pressure-decreasing valve (67).
