摘要： The present invention reduces lowering in control accuracy for a hydraulic pressure in a brake cylinder, which lowering is caused by vibrations of a hydraulic pressure in an upstream portion due to operations of a slip control device during anti-lock control.
The vibrations of the hydraulic pressure in the upstream portion are transmitted to a control pressure chamber via a pressurizing piston of a master cylinder and a control piston of a regulator. During anti-lock control, in contrast, a pressure-increase linear valve and a pressure-reduction linear valve are opened, allowing change in volume of the control pressure chamber, resulting in reduction in stiffness. This reduction suppresses vibrations of a hydraulic pressure in the control pressure chamber, resulting in suppression of vibrations of a hydraulic pressure in a front pressure chamber. As a result, it is possible to reduce the lowering in control accuracy for the hydraulic pressure in the brake cylinder in anti-lock control using the hydraulic pressure in the front pressure chamber, which can well avoid a long braking distance.
摘要翻译：本发明降低了制动液压缸中的液压的控制精度降低，这是由于在防抱死控制期间由于滑动控制装置的操作而导致的上游部分的液压振动引起的。上游部分的液压振动通过主缸的加压活塞和调节器的控制活塞传递到控制压力室。相反，在防抱死控制期间，打开增压线性阀和减压直线阀，允许控制压力室的体积变化，从而降低刚度。该减小抑制了控制压力室中的液压的振动，从而抑制了前压力室中的液压的振动。其结果是，能够利用前压力室内的液压降低防抱死控制中的液压的控制精度，能够避免长的制动距离。
