    • A brake control system for effectively properly performing a braking hydraulic pressure distribution between a front wheel and a rear wheel or a left wheel and a right wheel of a motor vehicle including a master cylinder for generating a hydraulic pressure in response to depression of a brake pedal thereof and applying the hydraulic pressure through first and second braking passages to first and second wheel braking cylinders. This brake control system has first and second pressure control devices respectively coupled to a braking pressure source for allowing the output hydraulic pressures to be regulated independently of each other under control of a control unit. The output of the first pressure control device is coupled through the first braking passage to the first wheel braking cylinder and the output of the second pressure control device is coupled through the second braking passage to the second wheel braking cylinder. The control unit determines first and second target braking pressures to the first and second wheel braking cylinders on the basis of the hydraulic pressure in the master cylinder. The determined first and second target braking pressures are respectively corrected on the basis of the vehicle acceleration and wheel slip ratios.
    • 一种制动控制系统,用于有效地正确地执行机动车辆的前轮与后轮或后轮或左轮和右轮之间的制动液压分布,所述制动液压分配包括用于响应于制动踏板的下压产生液压的主缸 并且通过第一和第二制动通道将液压施加到第一和第二轮制动缸。 该制动控制系统具有分别联接到制动压力源的第一和第二压力控制装置,用于允许在控制单元的控制下彼此独立地调节输出液压。 第一压力控制装置的输出通过第一制动通道联接到第一车轮制动缸,并且第二压力控制装置的输出通过第二制动通道联接到第二车轮制动缸。 控制单元基于主缸中的液压确定第一和第二车轮制动缸的第一和第二目标制动压力。 基于车辆加速度和车轮滑移率,分别校正所确定的第一和第二目标制动压力。

    • Wheel cylinders supplied with oil pressure from a master cylinder are respectively provided in brake mechanism provided in wheels of a vehicle. The wheel cylinder has a brake piston provided to form a first fluid chamber to supply oil pressure from the master cylinder, and a brake piston driven by the oil pressure of the first fluid chamber. The wheel cylinder has a piston mechanism formed by laminating thin plate shaped piezoelectric elements, and the piston mechanism is controlled to be expanded or contracted by controlling the voltage applied to the piezoelectric elements to vary the volume of the first fluid chamber. Cut-off valves are provided in passages for supplying the oil pressure from the master cylinder to the wheel cylinders, a check valve for allowing only the work oil to flow from the master cylinder to the wheel cylinder in parallel with the cut-off valve to control to expand the piston in the state the oil pressure is generated from the master cylinder and the cut-off valve is closed to control to further strengthen the oil pressure in the first fluid chamber.
    • 提供有来自主缸的油压的轮缸分别设置在设置在车辆的车轮中的制动机构中。 轮缸具有制动活塞,该制动活塞设置成形成第一流体室,以从主缸提供油压,以及由第一流体室的油压驱动的制动活塞。 轮缸具有通过层叠薄板状压电元件而形成的活塞机构,并且通过控制施加到压电元件的电压来改变第一流体室的体积来控制活塞机构的膨胀或收缩。 截止阀设置在用于将主缸的油压供给到轮缸的通道中,止回阀仅允许工作油从截止阀平行地从主缸流到轮缸, 控制在从主缸产生油压的状态下膨胀活塞,并且截止阀被关闭以控制以进一步增强第一流体室中的油压。
