摘要： When a brake switch is switched from OFF to ON, current is applied to a brake ECU, and a command to switch a master cylinder from a second state to a first state is issued after a lapse of preparation time, so that switching-time change suppression control is performed. A reservoir shutoff valve is closed, and duty control is performed on a communication control valve. The duty ratio is set to 1 when a switching-time control duration expires, and the communication control valve is placed in an open position, to establish the first state. Thus, since the communication control valve is duty-controlled during switching from the second state to the first state, change in the hydraulic pressure of an input chamber is suppressed, and change of the operating feeling is suppressed.
摘要翻译：当制动开关从OFF切换到ON时，电流被施加到制动ECU，并且在准备时间过去之后发出将主缸从第二状态切换到第一状态的命令，从而切换时间改变进行抑制控制。关闭一个油藏截止阀，在通讯控制阀上执行占空比控制。当切换时间控制持续时间到期时，将占空比设定为1，并且将通信控制阀置于打开位置，以建立第一状态。因此，由于在从第二状态切换到第一状态时对通信控制阀进行占空比控制，所以抑制了输入室的液压的变化，抑制了操作感的变化。

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： A hydraulic brake system is configured such that a pressure of a working fluid from a high-pressure-source device is adjusted by electromagnetic pressure-increase and pressure-decrease linear valves and such that a brake device generates a braking force having a magnitude that depends on the pressure adjusted by the linear valves, wherein the following controls are selectively executable, as a control of the energizing currents supplied to the linear valves, a feedback control based on a difference between an actual braking-force index and a target braking-force index; and a feedforward control based on the target braking-force index executed by placing each valve in a valve equilibrium state, wherein, in the feedforward control, an energizing current is supplied to at least one of the two linear valves, the energizing current being larger than that according to a preset relationship between a braking-force index and an energizing current in the valve equilibrium state.
