摘要： A hydraulic brake system for braking a vehicle, including a master cylinder device having a fluid-flow permission mechanism that permits a flow of a working fluid between an inter-piston chamber and a low-pressure source, wherein, when a pressure of the working fluid to be supplied to a brake device exceeds a set pressure upon advancing in association with an advancing movement of a brake operation member, a closing and opening mechanism for hermetically closing the inter-piston chamber and opening an opposing chamber to the low-pressure source is controlled so as to hermetically close the inter-piston chamber, while, when the pressure of the working fluid becomes lower than a set pressure upon retracting in association with a retracting movement of the brake operation member, the fluid-flow permission mechanism is controlled so as to permit the flow of the working fluid between the inter-piston chamber and the low-pressure source.

摘要： First hydraulic-pressure supply piping extended from an accumulator is connected to a first supply port (that is, to a second pressure chamber) of a cylinder, and to second hydraulic-pressure delivery piping of an ABS via third hydraulic-pressure supply piping having a third linear valve. When the braking hydraulic pressure Pf is reduced in the ABS, the degree and the period of time that the third linear valve is opened are set according to the amount of fluid discharged from the second hydraulic-pressure delivery piping to a reservoir tank through a pressure-reducing valve so that a certain amount of fluid is returned from the first hydraulic-pressure supply piping to the second hydraulic-pressure delivery piping via the third hydraulic-pressure supply piping.

摘要： In a brake control device and a brake control method, when a shift to a brake mode for backup involving separation of a supply path of working fluid is performed at the time of detection of an abnormality during braking, a differential pressure acting between an outlet opening and an inlet opening of an open-close valve which is provided between a hydraulic pressure source that is used during the backup brake mode and wheel cylinders and which needs to be opened during the backup brake mode is lessened prior to the separation of the supply path of working fluid so that the open-close valve is opened in accordance with a valve-opening command. Therefore, at the time of switch of the control mode, the confinement of wheel cylinder pressure is avoided.

摘要： In a vehicle brake control device, it is determined whether a first starting condition, that a master cylinder pressure and a rate of change of the master cylinder pressure are equal to or more than respective first reference values, is satisfied. Furthermore, it is determined whether a second starting condition is satisfied based on a determination as to whether the master cylinder pressure is equal to or more than a second reference value at a time when a predetermined time has elapsed since a time when the first starting condition was satisfied. In a case where the second starting condition is determined as being satisfied, a brake assist control is executed until a termination condition of the brake assist control is satisfied.

摘要： When the increasing gradient of the operating power is larger than a predetermined gradient, if a master pressure PM2 corresponding to a second predetermined operating power F2 is larger than a second predetermined fluid pressure Pth2, a servo function failure in the brake operation is determined; if it is smaller than the second predetermined fluid pressure Pth2, fluid leakage failure (S23, S26, S27) is determined. Furthermore, if the master pressure PM0 corresponding to the first predetermined operating power F0 is larger than a first predetermined fluid pressure Pth1, small amount fluid leakage failure is determined; if it is smaller than the first predetermined fluid pressure Pth1, large amount fluid leakage failure (S28, S29, S30) is determined. On the other hand, when the increasing gradient of the operating power is smaller than a predetermined gradient, if the master pressure PM0 is smaller than the first predetermined fluid pressure Pth1, servo function failure is determined; if it is larger than the first predetermined fluid pressure Pth1, the normal condition (S32, S33) is determined. Therefore, the type of the failure can be detected based on both the operating power and the master pressure.
摘要翻译：当操作功率的增加梯度大于预定梯度时，如果对应于第二预定操作功率F2的主压力PM2大于第二预定流体压力Pth2，则确定制动操作中的伺服功能故障; 如果小于第二预定流体压力Pth2，则确定流体泄漏故障（S23，S26，S27）。此外，如果对应于第一预定运行功率F0的主压力PM0大于第一预定流体压力Pth1，则确定少量的流体泄漏故障; 如果小于第一预定流体压力Pth1，则确定大量的流体泄漏故障（S28，S29，S30）。另一方面，当操作功率的增加梯度小于预定梯度时，如果主压力PM0小于第一预定流体压力Pth1，则确定伺服功能故障; 如果大于第一预定流体压力Pth1，则确定正常状态（S32，S33）。因此，可以基于操作功率和主压力来检测故障的类型。
