摘要： A method and apparatus for controlling brakes using a reciprocating cut valve actuated by an expander piston that is moved via a crank pin on a crank shaft. The cut valve cuts off caliper pressure and adjusts the volume and pressure of an output hydraulic chamber to effectuate antilock braking. When changing from antilock braking to normal braking, the movement of the expander piston is controlled by repeatedly changing a crank angle of the crank pin during specified time intervals. The rate of increase in caliper pressure can be set according to (1) detected brake operation which is detected from a present crank angle and a target crank angle and (2) the frictional state of the road surface which is estimated from vehicle acceleration/deceleration.

摘要： An electrically controlled fluid displacement piston positioned in a bore modulates braking pressure at a wheel brake for antilock controlled braking by modulating the position of the piston in the bore. At a fully extended home position, a check valve is unseated by the piston to hydraulically couple the brake system master cylinder to the wheel brake. To minimize the occurrences of the condition where the check valve is opened during ABS controlled braking, the piston is initialized prior to entry into antilock controlled braking at a position away from the check valve resulting in a greater volume of fluid being trapped upon entry into antilock controlled braking when a hydraulic passage in parallel with the check valve is closed in response to a detected incipient wheel lock condition. This permits the antilock brake system to apply a controlled brake pressure greater than the pressure initially trapped in the closed system. The position of the displacement piston is monitored and when the piston approaches the position at which the check valve will be opened thereby opening the fluid communication between the master cylinder and wheel brake, the antilock brake system control parameters are adjusted to increase the system sensitivity to wheel slip.
摘要翻译：定位在孔中的电控流体置换活塞通过调节活塞在孔中的位置来调节车轮制动器处的制动压力以防止锁定制动。在完全伸出的起始位置，止回阀被活塞释放，以将制动系统主缸液压耦合到车轮制动器。为了最小化在ABS控制制动期间止回阀打开的状况的发生，在离开止回阀的位置进入防抱死控制制动之前，活塞被初始化，导致在进入防抱死时被捕获的更大体积的流体当与止回阀平行的液压通道响应于检测到的初始轮锁定状态而关闭时，控制制动。这允许防抱死制动系统施加大于最初被封闭在封闭系统中的压力的受控制动压力。监测位移活塞的位置，当活塞接近止回阀打开的位置，从而打开主缸和车轮制动器之间的流体连通时，调整防抱死系统控制参数以提高系统的灵敏度轮滑。

摘要： A solenoid-operated fluid-flow control valve comprising a single solenoid coil, the energization of which controls the movement of first and second armatures which in turn control first and second respective valve members. The armatures are biased away from the solenoid by respective springs, one of which is weaker than the other. When the solenoid is energized by a constant current the armature with the weaker spring is attracted to the end of the solenoid and forms part of a magnetic circuit. This increases the magnetic flux at the other end of the solenoid, allowing the second armature to be drawn to the solenoid sequentially after, and subsequent to, the drawing-in the of the first armature. Particular anti-lock brake systems incorporating the valve are disclosed.

摘要： The hydraulic braking circuit between the master cylinder and the wheel cylinder is provided with a valve for interrupting fluid communication therebetween and a movable member for selectively increasing and decreasing the effective volume of a portion of the hydraulic circuit. A sensor is provided for sensing the rotation of at least one of the wheels of the vehicle and delivering an instruction signal when the wheel is subjected to an excess braking beyond a predetermined deceleration of the wheel. The signal from the sensor operates a change-over valve which increases the effective volume of the portion of the hydraulic circuit by actuating the movable member. A detector is provided for detecting maximum deceleration of the wheel during braking and the maximum value of the detected wheel deceleration is preserved in a memory. The detected maximum wheel deceleration and the rate of change of the effective volume of the hydraulic circuit are converted into effective electric signals. An orifice valve controls the rate of effective volume reduction in the hydraulic circuit in response to a comparison of the electric signals.

摘要： In vibrating a spool of a spool-valve type electromagnetic proportional pressure control valve by applying a dither current so that no static friction acts on the spool, the dither effect tends to weaken in a region where the current is small and in a region where the current is so large as to cause magnetic saturation. An alternating dither current is superimposed on the current supplied to an electromagnet to vibrate the spool with an amplitude small enough not to affect the liquid pressure, and in a control region where the ratio of the solenoid force Fsol to the current I is small, the dither current is controlled so that its amplitude is larger or its frequency is lower than in other regions.

摘要： An antilock liquid-pressure control apparatus includes a first liquid-pressure control mechanism and a second liquid-pressure control mechanism. A second liquid chamber in the first liquid-pressure control mechanism is communicatively connected to a wheel cylinder, and through a check valve to a pressure chamber of a master cylinder. A first liquid chamber in the first liquid-pressure control mechanism is communicatively connected to a discharge port of a liquid pressure pump and a liquid chamber in the second liquid-pressure control mechanism, through a flow control valve, and further to a reservoir through a decay valve. A spring container in the second liquid-pressure control mechanism communicates with the pressure chamber of the master cylinder. In a pressure reduction mode of the antilock control, the brake liquid is sucked from the first liquid chamber by the liquid pressure pump, and the sucked brake liquid is accumulatively pressurized in the liquid chamber of the record control mechanism, and the brake liquid is returned from the spring container to the master cylinder. In a pressure reapplication mode of the antilock control, the brake liquid is supplied from the liquid chamber of the record control mechanism to the first liquid chamber, through the flow control valve.

摘要： A system for feedback-free ABS control in hydraulic brakes for mobile units, motor vehicles, motorcycles, and the like, equipped with a pedal-actuated master brake cylinder with a hydraulic brake booster and at least one isolation or shutoff valve in the form of a 3/2-way magnetic valve, which in normal operation is supplied with pressure by the master brake cylinder booster and is also assigned a plunger-piston for performing an ABS control. A check valve is disposed in the connecting line between the isolation valve, the ABS magnetic valve and the plunger-piston, or in a common supply line from the dynamic circuit of the master brake cylinder to these three actuating elements, as additional protection for the isolation valve and to assure the required brake pressure, even in the case of a failure, to keep the chambers of the hydraulic isolation valve and the rear chamber of the plunger-piston under pressure and in this way arrest the pistons so that they cannot move during normal braking operation. A pressure control valve can be disposed parallel to the check valve to limit the pressure in case of expansion of the fluid in the chambers, for example, by heating.
