    • In a brake booster of the present invention, by depression of a brake pedal 3, an input shaft 4 travels to the left, a pedal input converter generates thrust, and a valve element 5a moves to the left. A valve passage 5a1 is shut off from a valve passage 5b1 and a valve passage 5a2 is connected to a valve passage 5b2 so as to develop output pressure Pr at an output port 5c of a control valve 5 because of the pressure of a pressure source. The output pressure Pr is supplied to a wheel cylinder 7, thereby actuating the brake. At this point, since the displacement of the input shaft 4 required for operating the control valve 5 is defined only by the converter 6, the input side is not affected by the brake rigidity of a circuit from the control valve 5 to the wheel cylinder 7. The output pressure Pr of the control valve 5 acts on the valve element 5a through a first reaction receiving portion 8 and is regulated to pressure proportional to the thrust of the converter 6. The second reaction force is transmitted to a driver through a second reaction receiving portion 9. The control of the output can be conducted during the operation regardless of the input of the input side and the respective characteristics can be varied without being affected by the output side.
    • 在本发明的制动助力器中,通过按压制动踏板3,输入轴4向左行驶,踏板输入转换器产生推力,阀元件5a向左移动。 阀通道5a1从阀通道5b1截止,阀通道5a2连接到阀通道5b2,以便由于压力源的压力而在控制阀5的输出端口5c处产生输出压力Pr。 输出压力Pr被提供给轮缸7,从而致动制动器。 此时,由于仅通过转换器6来限定操作控制阀5所需的输入轴4的位移,所以输入侧不受从控制阀5到轮缸7的回路的制动刚度的影响 控制阀5的输出压力Pr通过第一反应接收部8作用在阀体5a上,并被调节成与转换器6的推力成正比的压力。第二反作用力通过第二反应传递给驾驶员 输出的控制可以在操作期间进行,而与输入侧的输入无关,并且可以改变各个特性而不受输出侧的影响。

    • The invention relates to a brake system including a brake booster. A pneumatic pressure operated brake booster VBB or a liquid pressure operated brake booster includes a valve mechanism which is urged by a force of depression applied to a brake pedal BP to switch a flow path to cause the brake booster to develop an output which depends on the magnitude of the force of depression. A solenoid SOL urges the valve mechanism in the same direction as or in the opposite direction from the force of depression. A controller ECU is responsive to a braking effort increase/decrease demand signal to increase or decrease the urging force which is applied by the solenoid to the valve mechanism, thus increasing or decreasing the output from the brake booster. An output from the brake booster can be freely controlled independently from the force of depression applied to the brake pedal in response to a braking effort increase/decrease demand. The arrangement is applicable to a wide variety of brake systems onboard a vehicle such as a regenerative brake unit, an engine brake or an exhaust gas brake unit or a brake assisting apparatus.

    • In a braking pressure intensifying master cylinder, as an input shaft (53) travels forwards in a braking maneuver, a control valve (54) is actuated to develop fluid pressure according to the input in a reaction chamber (38) and a pressurized chamber (35). A stepped spool (45) as a part of the control valve 54 travels such that force produced by the fluid pressure and spring force of a spring (51) are balanced, whereby the stepped spool (45) can function as a travel simulator. By changing the pressure receiving areas of the stepped spool and/or changing the spring force of the spring (51), the travel characteristic of the input shaft (53) as the input side can be freely changed independently from the output side, without influence on a master cylinder pressure as the output side of the braking pressure intensifying a master cylinder (1). In addition, the master cylinder pressure can be intensified when necessary with a simple structure.

    • A fluid pressure boosting device of the present invention performs jumping action at a higher servo ratio until fluid pressure in a power chamber (25) reaches a first predetermined value and a rear end (20e) of a reaction piston (20)comes in contact with a step of an input shaft (18). Since a switching valve is set in a first position I until the fluid pressure in the power chamber (25) reaches a second predetermined pressure, a reaction chamber (41) is connected to the reservoir (33) so as to be at atmospheric pressure. In this state, the normal brake control at a lower servo ratio is performed. As the fluid pressure in the power chamber (25) reaches a second predetermined value, the switching valve is set in a second position II by the fluid pressure so that the pressurized fluid in the power chamber is introduced into the reaction chamber (41). The fluid pressure in the reaction chamber 41 acts on the step between the reaction piston (20) and the input shaft (18) so that the servo ratio becomes higher. Then, the servo control at a higher servo ratio is performed. The fluid pressure boosting device can be provided with the reversed two-stage servo characteristic, so with simple structure, output larger than the normal output can be obtained when input exceeds a predetermined value.
    • 本发明的流体增压装置以更高的伺服比执行跳动,直到动力室25中的流体压力达到第一预定值,并且反作用活塞(20)的后端(20e)与 输入轴(18)的台阶。 由于在动力室25内的流体压力达到第二预定压力之前将切换阀设定在第一位置I,所以将反应室41与储存器33连接成大气压。 在该状态下,执行较低伺服比的正常制动控制。 当功率室25中的流体压力达到第二预定值时,通过流体压力将切换阀设定在第二位置II,使得动力室中的加压流体被引入到反应室41中。 反应室41中的流体压力作用在反应活塞(20)和输入轴(18)之间的台阶上,使得伺服比变高。 然后,执行伺服控制以较高的伺服比。 流体增压装置可以设置反向两级伺服特性,结构简单,当输入超过预定值时,可以获得大于正常输出的输出。

    • A field delay circuit aligns the phases of two field signals. An average value calculation circuit generates an average value signal of the two field signals. This average value signal can be regarded as a signal that has undergone a one-dimensional low-pass filter process in the row direction in which the number of taps for a progressive signal is 2 and the filter coefficient for each tap is 0.5 and that has then been thinned to one-half the data. A two-dimensional LPF circuit subjects this average value signal to a low-pass filter process and eliminates the high-frequency components (edge components). A subtraction circuit subtracts the average value signal that has undergone the LPF process from each field signal and thus extracts the edge components of each field signal. An amplification circuit multiplies the edge components of each field signal by a prescribed factor. An addition circuit adds the resulting amplified edge components to each field signal.
