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： When a vehicle stops, a brake control unit maintains a braking force applied on a wheel by a braking-force application unit for maintaining a halted state. In this state, if a driver depresses the accelerator pedal to execute starting of the vehicle, the braking force is gradually decreased, and the vehicle starts at a speed that accords with a degree of accelerator opening and a gradient of a road on which the vehicle is stopped. When a movement direction at this time is the same as a movement direction intended by the driver, the braking force is decreased to zero for smooth starting. When the movement direction is opposite to the intended movement direction, the braking force is increased to control the movement in the opposite direction, such that the movement changes from the opposite direction to the same direction, and finally, smooth starting in the desired direction is executed.
摘要翻译：当车辆停止时，制动控制单元通过用于维持停止状态的制动力施加单元保持施加在车轮上的制动力。在该状态下，如果驾驶员按下加速器踏板来执行车辆的起动，则制动力逐渐减小，车辆以与加速器开度的程度和车辆的坡度一致的速度起动，被停止当此时的运动方向与驾驶员的运动方向相同时，为了顺利起动，制动力降低到零。当移动方向与预期的移动方向相反时，增加制动力以控制相反方向的移动，使得移动从相反方向向同一方向变化，最后在期望的方向上平滑地开始执行。

摘要： A brake system has wheel cylinders for producing a braking force in wheels using pressurized brake fluid transmitted through a main conduit from a master cylinder, a reservoir for storing brake fluid, a sideslip preventing device for when a sideslip state of the vehicle is detected supplying brake fluid to the wheel cylinder corresponding to a sideslip controlled wheel and producing a braking force in the sideslip controlled wheel, a first conduit used for supplying brake fluid from the reservoir to the wheel cylinders by the pump and a first valve for switching this first conduit between an open state and a closed state. The sideslip preventing device, when the sideslip state is detected during non-braking of the vehicle, makes the first valve open-state and thereby conducts supply of brake fluid through the first conduit from the reservoir to the wheel cylinder by a pump. When the sideslip state is detected during braking of the vehicle, the sideslip preventing device makes the first valve device closed-state and thereby prohibits supply of brake fluid from the reservoir to the wheel cylinder.

摘要： When oil flows from within a seat valve along an oil path in a valve, structure is such that a negative pressure is generated to draw a ball in the direction of the seat valve. That is, the force in the direction of valve closure is actively utilized, the valve does not perform a full stroke in a certain differential pressure range, and increases in a pulsed manner in a minute-stroke state, i.e., in a state where the passage cross-sectional area of the valve is small. Therefore, effective control becomes possible without a large pressure increase.

摘要： A brake control system for effectively properly performing a braking hydraulic pressure distribution between a front wheel and a rear wheel or a left wheel and a right wheel of a motor vehicle including a master cylinder for generating a hydraulic pressure in response to depression of a brake pedal thereof and applying the hydraulic pressure through first and second braking passages to first and second wheel braking cylinders. This brake control system has first and second pressure control devices respectively coupled to a braking pressure source for allowing the output hydraulic pressures to be regulated independently of each other under control of a control unit. The output of the first pressure control device is coupled through the first braking passage to the first wheel braking cylinder and the output of the second pressure control device is coupled through the second braking passage to the second wheel braking cylinder. The control unit determines first and second target braking pressures to the first and second wheel braking cylinders on the basis of the hydraulic pressure in the master cylinder. The determined first and second target braking pressures are respectively corrected on the basis of the vehicle acceleration and wheel slip ratios.

摘要： A floating plate is provided in a cylinder chamber and slides freely like a piston. A first group of laminated, ring-shaped, thin-plate piezoelectric elements is provided between a fixed support member provided on part of a wall portion of this cylinder chamber and the floating plate. A second group of laminated, cylindrical, thin-plate piezoelectric elements is provided in the center of the first group and a working member is provided on the free end of the second group of elements that is not attached to the floating plate. A hydraulic chamber is formed in the cylinder chamber on the side of the floating plate opposite to the side on which the first and second groups of elements are provided, and the pressure in this hydraulic chamber pushes the floating plate in the direction of the fixed support member. Voltage is applied to the first and second groups of elements to expand and contract them thereby varying the distance between the floating plate and the fixed support member and varying the distance between the floating plate and the working member.
