摘要：压力增大和降低的范围随因刹车流体温度的变化而导致的刹车流体粘度的变化的变化和因刹车流体粘度变化而导致的压力增大和降低的延迟降低至最小。使用具有零点温度漂移功能和无此功能的压力传感器,根据两个传感器输出差估算刹车流体的温度。流体压力可以相应于根据估算的流体温度的流体粘度的控制方式进行控制。改变了电磁阀开启的周期,或在采用电磁控制压力比例阀的装置中,根据刹车流体温度改变电磁铁的电流。

摘要： An antiskid control device (K1-K5) which calculates an estimated fluid pressure (PT i ) of each of wheel cylinders (2A-2D) under antiskid control in each control cycle so as to adjust a fluid pressure of each of the wheel cylinders (2A-2D) on the basis of the estimated fluid pressure (PT i ) and behaviors of wheels, comprising: a differential pressure detecting member
which detects a difference between a fluid pressure of a master cylinder (1) and the fluid pressure of each of the wheel cylinders (2A-2D) so as to produce an output signal indicative of the difference between the fluid pressure of the master cylinder (1) and the fluid pressure of each of the wheel cylinders (2A-2D); wherein when on the basis of the output signal of the differential pressure detecting member (SS, SSW, PSW i , SPS i ), the difference between the fluid pressure of the master cylinder (1) and the fluid pressure of each of the wheel cylinders (2A-2D) is found to be in the vicinity of zero, the estimated fluid pressure (PT i ) of each of the wheel cylinders (2A-2D) is set to a predetermined value (PTmax) by stopping addition in calculation of the estimated fluid pressure (PT i ).

摘要： At vehicle startup and vehicle shutdown, the driver modulates the brake pressure directly by depressing the brake pedal and the driver feels pedal resistance. During normal conditions of vehicle operation after vehicle startup, pressure boosted actuation of the vehicle brakes is provided by the modulation of boosted pressure from an accumulator via a boost valve operable in response to brake pedal depression, while an isolation valve isolates the pedal from direct influence by the brake pressure and the driver feels pedal resistance provided by a pedal simulator. Upon shutdown of boosted actuation, the boost valve reduces the brake pressure gradually over a calibrated period of time until the brake pressure substantially equals the pedal resistance then felt by the driver. Then the isolation valve reestablishes driver's feel of the brake pressure without an abrupt change in pedal resistance upon the reversion from boosted actuation to hydraulic unboosted actuation.
摘要翻译：在车辆启动和车辆关闭时，驾驶员通过按下制动踏板直接调节制动压力，驾驶员感觉踏板阻力。在车辆启动后的车辆操作的正常状态期间，通过经由可响应于制动踏板下压的可操作的升压阀从蓄能器调节增压压力来提供车辆制动器的增压致动，而隔离阀将踏板与直接影响隔离通过制动压力和驾驶员感觉踏板模拟器提供的踏板阻力。在关闭升压致动时，升压阀在校准的时间段内逐渐降低制动压力，直到制动压力基本上等于驾驶员感觉到的踏板阻力。然后隔离阀重新建立驾驶员的制动压力感觉，而在从升压致动向液压未启动致动反转时，踏板阻力突然改变。

摘要： An upper limit of a target value of a wheel cylinder pressure generated by a wheel cylinder is set. Specifically, the upper limit of the target value is predetermined and increases with elapsed time from the beginning of the control. Accordingly, the actual application pressure generated can be set to be equal to or less than the upper limit. Thus, it is possible to prevent the application pressure from being dramatically increased when the automatic brake control is switched to a manual brake control from automatic brake control. Accordingly, it is less likely that the driver will be caused to feel a sense of unease by a change from automatic to manual brake control.
摘要翻译：设定由轮缸产生的轮缸压力的目标值的上限。具体地，目标值的上限是预定的，并且随着从控制开始的经过时间而增加。因此，生成的实际施加压力可以设定为等于或小于上限。因此，当自动制动控制从自动制动控制切换到手动制动控制时，可以防止施加压力急剧增加。因此，由于从自动到手动制动控制的变化，驾驶员不太可能感到不安感。

摘要： A vehicle brake actuator has a piston (23) within a cylinder (22) for urging friction pad assemblies (19, 20) into braking engagement with a brake disc (21). The actuator incorporates a pressure accumulator (3) and an electrical valve (9) operable to supply pressure from the accumulator to the cylinder in response to the action of a brake pedal or other control means. The actuator may also incorporate a pump (1) for charging the accumulator, together with other equipment such as skid control means. A braking system incorporates one or more of the actuators and means for producing an electrical output in response to displacement of the brake control means for supply to the valve.

摘要： A lower limit of a target value of a wheel cylinder pressure generated by a wheel cylinder is set as a first value PT1. Specifically, the first value PT1 is determined based on the application pressure generated by the wheel cylinder during an automatic brake control. Accordingly, the actual application pressure generated can be set to be equal to or more than the first value PT1. Thus, it is possible to prevent the application pressure from being decreased unintentionally when the automatic brake control is switched to a manual brake control, and thus, it is possible to maintain a deceleration speed of a vehicle at the level of a vehicle body deceleration generated during the automatic brake control. Accordingly, it is less likely that the driver will be caused to feel a sense of unease by weakening of the braking force.
摘要翻译：由轮缸产生的轮缸压力的目标值的下限被设定为第一值PT 1。具体地说，第一值PT 1是基于在自动制动控制期间由轮缸产生的施加压力来确定的。因此，可以将生成的实际施加压力设定为等于或大于第一值PT 1。因此，当自动制动控制切换到手动制动控制时，可以防止施加压力的无意降低，从而可以将车辆的减速度保持在车体减速度的水平上在自动制动控制期间。因此，通过削弱制动力，驾驶员不太可能感到不安感。
