摘要： The similarity groups of the pressure differential—current characteristics of solenoid valves are measured in advance, and the measurement results are used to select the solenoid valves to be used for first to fourth pressure increase control valves. Only solenoid valves in the same region in terms of their similarity group of the pressure differential—current characteristics are used for the first to fourth pressure increase control valves. A board on which the first to fourth control valves are mounted is provided with a mark unit that indicates the similarity group of the pressure differential—current characteristics of the first to forth pressure increase control valves. The mark unit includes a resistor. A brake ECU uses the resistance value of the resistor to identify the similarity group of the pressure differential—current characteristics of the first to fourth pressure increase control valves.

摘要： Control system for controlling an anti-lock braking system having a brake for a wheel of a motor vehicle, wherein a skidding or locking condition of the wheel is detected by a detector based on a running condition of the vehicle and a rotating condition of the wheel, and a slip ratio of the vehicle is maintained within an optimum range by a pressure-regulating device, by increasing, decreasing and holding a brake fluid pressure applied to the brake, in response to the detected locking condition of the wheel. A predetermined pressure-decrease time during which the fluid pressure is decreased is measured by a measuring device, and a deceleration rate of a rotating speed of the wheel when the pressure-decrease time has elapsed is detected by a detecting device. A device is provided for determining an extension time during which the fluid pressure is further decreased, such that the extension time increases with the detected deceleration rate of the wheel. The pressure-regulating device is activated to further decrease the fluid pressure for the determined extension time.

摘要： The invention is directed to an arrangement for controlling a braking force applied to each of road wheels of a vehicle depending upon a braking condition, with a hydraulic braking pressure supplied to each of the wheel brake cylinders through an actuator. The actuator is controlled by a braking force controller into which output signals of wheel speed sensors are fed. The hydraulic braking pressure applied to each of the wheel brake cylinders is controlled by the braking force controller in accordance with each wheel speed. And, it is determined whether the vehicle is turning or not. If the vehicle is turning, the hydraulic braking pressure in a wheel brake cylinder operatively connected to one of the rear road wheels positioned at the outer side is controlled such that a decreasing operation of the pressure is restrained for at least a predetermined time period.

摘要： The invention is directed to an arrangement for controlling a braking force applied to each of driven wheels and non-driven wheels depending upon a braking condition, with a hydraulic braking pressure supplied to each of wheel brake cylinders through an actuator. The actuator is controlled by the braking force controller into which output signals of wheel speed sensors are fed. The braking force controller is arranged to control the hydraulic braking pressure supplied to each of the wheel brake cylinders. When one driven wheel is under the anti-skid control, it is determined whether a difference speed between the driven wheels is greater than a predetermined value. If it is determined that the difference speed is greater than the predetermined value, the actuator is actuated to restrain the hydraulic braking pressure from being supplied to the wheel brake cylinder operatively connected to the other driven wheel, e.g., to hold the hydraulic braking pressure supplied to the wheel brake cylinder, or to reduce a rate of increase of the hydraulic braking pressure.

摘要： A braking control device for a vehicle executes braking force distribution (BFD) biased to the front wheels, taking into account auxiliary braking control such as braking assist control (BAS) executed when an abrupt or full braking action is performed by the driver. In BFD control a braking force on the rear wheels is held at a holding braking force and a braking force on the front wheels is incremented beyond a braking force requested by a braking action of the driver. After the starting of BFD control, further increase in the braking action is reflected in the braking force of the front wheels. When auxiliary braking control is executed, the holding braking force on the rear wheels and the increment of the braking force on the front wheels are determined based upon a demand of the auxiliary braking action as well as the braking action amount by the driver.

摘要： A braking control device for a vehicle executes braking force distribution (BFD) biased to front wheel in a manner compatible with Anti-skid control. In BFD control, braking force on rear wheels is held at a holding braking force and braking force on the front wheels is incremented beyond braking force requested by a braking action of a driver. After the starting of BFD control, further increase in the braking action is reflected in the front wheel braking force. Upon starting anti-skid control for either of the wheels during the execution of BFD control, an increment of the front wheel braking forces to be requested by BFD control is gradually decreased. Simultaneously, the holding of the rear braking force is released so as to compensate for the shortage of braking force on the front wheel. The gradual decrease of the braking force increment prevents a conflict of BFD and Anti-skid control.

摘要： A braking apparatus includes a braking mechanism that increases operating force to a brake operating member by a brake servo, generates braking force exerted on wheels corresponding to the increased operating force, and is capable of holding the braking force when a vehicle stops, and a controller that executes braking force holding control to hold the braking force when an operation amount of the brake operating member corresponding to the operating force becomes larger than a control start judgment value, and sets the control start judgment value to be smaller than the control start judgment value in a normal state of the brake servo when the brake servo fails. The braking force can be appropriately held.

摘要： A braking control device of a vehicle starts executing braking force distribution (BFD) biased to front wheels for avoiding the locking of rear wheels prior to the front wheel at appropriate time by reducing errors of a judgment of the starting of the control. Usually, the BFD control is started in response to the increase of a master cylinder pressure, assuming that the rear wheel braking pressure is equally increased. When a fast braking action occurs, the delay of the pressure variation of the rear wheel braking pressure relative to the master cylinder is conspicuous because the responsibility of a master cylinder pressure to the braking action is too fast. Thus, Upon a fast braking action, a judgment of starting of BFD control is made based upon a value involved with rear wheel braking force, such as an estimation value of the rear wheel braking pressure, having a slower responsibility to the braking action than the master cylinder pressure, and thereby preventing a premature start of the BFD control due to the delay of the rear wheel braking pressure. When a deceleration signal is used for the judgment of starting of BFD control, the signal is passed through a low-pass filter having a rather higher cut-off frequency on a fast braking action, in order to improve the responsibility of the signal to the braking action.
摘要翻译： 车辆的制动控制装置开始执行偏向前轮的制动力分配（BFD），以通过减少控制开始判断的错误来避免在适当的时刻在前轮之前锁定后轮。 通常，假设后轮制动压力相等地增加，响应于主缸压力的增加而启动BFD控制。 当发生快速制动作用时，后轮制动压力相对于主缸的压力变化的延迟是显着的，因为主缸压力对制动作用的负担太快。 因此，在快速制动动作时，基于与后轮制动力相关的值（例如后轮制动压力的估计值），对制动动作的责任比对比，进行BFD控制的判断为 主缸压力，从而防止由于后轮制动压力的延迟引起的BFD控制的过早启动。 当使用减速信号进行BFD控制启动判断时，信号通过具有较高截止频率的低通滤波器进行快速制动动作，以便将信号的责任提高到 制动动作。
