摘要： Vibration observed in a tire wheel portion exhibits a resonant vibration phenomenon in which vibration fluctuates between a wheel and a surface of a tire. This phenomenon shows different characteristics depending upon how the surface of the tire is in contact with a road surface. Here, a detector derives a parameter corresponding to a gradient of a coefficient of friction based on these characteristics and detects a brake condition. Also, a controller executes ABS control based on such parameter.

摘要： To provide optimal braking force control using braking operation data, an ECU in a brake force control system detects a braking operation according to fluctuation components of wheel rotation. That is, the ECU calculates the wheel acceleration and sets a reference load level for the braking operation according to a road surface coefficient of friction at the wheel tire. When the amplitude of the wheel acceleration increases and exceeds the reference load level, the braking load is determined to be heavy. If the braking load is heavy, the ECU decreases the brake oil pressure of the wheel being detected. In this way, the slip ratio can be controlled around a peak road surface coefficient of friction.
摘要翻译：为了使用制动操作数据提供最佳制动力控制，制动力控制系统中的ECU根据车轮旋转的波动分量来检测制动操作。也就是说，ECU计算车轮加速度，并根据车轮轮胎的路面摩擦系数设定制动操作的基准负载水平。当车轮加速度的振幅增加并超过参考负载水平时，制动负载被确定为很重。如果制动负载较重，ECU会降低被检测车轮的制动油压。以这种方式，可以围绕峰值路面摩擦系数控制滑移率。

摘要： A pressure control valve for use in an automobile braking system includes a spool slidably movable for providing selective fluid communication between a pressure fluid source, a wheel cylinder, and a reservoir. The spool has, or is associated with, a pressure-bearing member responsive to a fluid pressure from the wheel cylinder, for applying a first biasing force to the slidable member to urge the slidable member to a position in which the wheel cylinder and the reservoir communicates with each other. An electromagnetic coil responds to an electric signal for generating an electromagnetic force to urge the slidable member to the above position. The slidable member is normally biased by a spring under a second biasing force, greater than the first biasing force, to urge the slidable member to a position in which the pressure fluid source and the wheel cylinder communicate with each other. The fluid pressure in the wheel cylinder is regulated to cause the sum of the fluid pressure in the wheel cylinder and the electromagnetic force from the electromagnetic coil to counterbalance the second biasing force.

摘要： A vehicle brake device A is provided with a master cylinder 10, a reservoir tank 12, solenoid valves 46 and 48 for adjustably draining brake oil from outlet ports 10a, 10b of the master cylinder 10 to the reservoir tank 12, a collision detection sensor 68 for detecting a collision of the vehicle, a fluid pressure meter 61 for detecting the master cylinder pressure, and an ECU 70. The ECU 70 detects the pushing-up of the brake pedal 11 based on the occurrence of a collision and the master cylinder pressure, and upon detection of the pushing-up, controls the solenoid valves 46 and 48 to adjust the draining of the brake oil so that the brake pedal 11 is withdrawn. Thus, a time point when the brake pedal 11 begins to be pushed up by the cause of the vehicle collision can be detected accurately and reliably, and the brake pedal 11 can be withdrawn accurately in dependence on the pushing-up. This reliably secures an anchorage upon which the driver keeps his body balance and reliably prevents an excess load from being exerted on the driver.

摘要： If a pressure sensor is increased in size and therefore the inside diameter of a yoke is increased, a stopper is provided with a large-diameter portion. The large-diameter portion makes it possible to reduce the air gap between the stopper and the yoke and therefore suppress an increase in magnetic resistance. Besides, a magnetic circuit member is provided at an outer peripheral side of a sleeve. The magnetic circuit member makes it possible to reduce the air gap between the yoke and an armature and therefore suppress an increase in magnetic resistance.

摘要： There is a case where first and second pressurizing units press different portions of friction members to a brake disc so as to press the friction members to the brake disc with predetermined pressing force, thereby generating braking force. When the brake noise is generated, a distribution ratio of the pressing force is changed by changing at least one of the pressing force generated by the first pressurizing unit and the pressing force generated by the second pressurizing unit. Accordingly, when the friction member contacts the brake disc, it is possible to change pressure distributions between first portions and second portions, whereby the brake noise is reduced or suppressed.

摘要： An output signal that accords with a rotation speed of a brake rotor of a respective wheel is output by a vehicle wheel speed sensor. A noise frequency identification portion identifies a frequency component that corresponds to brake noise from this output signal. It is possible, for example, to identify a frequency component that corresponds to brake squeal by performing fast Fourier transform (FFT) calculation for the vehicle wheel speed. Further, a noise detection portion determines that brake noise is being generated when the frequency component identified by the noise frequency identification portion is equal to or more than a predetermined value.

摘要： A brake system includes first brake assist means arranged in a first brake circuit to increase a first wheel cylinder pressure to a level higher than a master cylinder pressure. The brake system further includes second brake assist means arranged in a second brake circuit to increase a second wheel cylinder pressure to a level higher than the master cylinder pressure. The second brake assist means includes a brake regulator mechanism that uses the increased first wheel cylinder pressure as a pilot pressure and adjusts the increased second wheel cylinder pressure to a pressure falling within a predetermined range from the increased first wheel cylinder pressure when the first brake assist means is activated.

摘要： The electromagnetic valve is comprised of first communication path and second communication path with a throttle connected in parallel to each other, a first plunger having a first valve for interrupting/communicating the first communication path and having a penetration hole extending to the second communication path, a second plunger having a second valve movable in or through the penetration hole for interrupting/communicating the second communication path, a spring member for generating spring biasing force and a coil member for generating an electromagnetic attracting force, when energized, to have the first and second plungers come close to each other against the spring biasing force. The electromagnetic valve may be controlled in a manner that the first communication path is interrupted and the second communication path is communicated at a pressure-increase timing during an anti-skid control.
