摘要： PROBLEM TO BE SOLVED: To provide a braking system for precisely controlling braking force. SOLUTION: The braking system controls hydraulic pressure passages between a master cylinder and each wheel cylinder so that the transmission coefficient of hydraulic pressure from the master cylinder to the wheel cylinders provided on wheels on a high μ load side becomes smaller as master cylinder pressure has a higher increasing speed when there are different friction coefficients between each of right and left wheels and a road surface. Even when the master cylinder pressure increases at a high speed, the transmission coefficient becomes smaller and so the wheel cylinder pressure dose not increase at a high speed, and even when the master cylinder pressure increases at a low speed, the transmission coefficient becomes larger and so the wheel cylinder pressure does not increase at a low speed. As a result, the increasing speed dependability of the wheel cylinder pressure on the master cylinder pressure is suppressed and the wheel cylinder pressure provided on the wheels on the high μ road side to be subjected to yaw control during travel on a crossover road, namely, braking force is more precisely controlled.

摘要翻译：要解决的问题：提供一种用于精确控制制动力的制动系统。
解决方案：制动系统控制主缸和每个车轮缸之间的液压通道，使得在主负载侧的车轮上设置的从主缸到轮缸的液压传动系数随着主缸当左右两轮和路面之间存在不同的摩擦系数时，压力具有较高的增加速度。即使主缸压力高速增加，传动系数变小，轮缸压力也不会以高速增加，即使主缸压力以低速度增加，传动系数变大，所以轮缸压力不会以低速增加。结果，抑制了轮缸压力对主缸压力的增加的速度可靠性，并且设置在高μ路侧的车轮上的轮缸压力在跨越道路行驶期间进行偏航控制，即，制动力更精确地控制。版权所有（C）2004，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an anti skid control device for a vehicle, capable of properly differential pressure between master cylinder pressure (M/C pressure) during ABS controlling and wheel cylinder pressure (W/C pressure). SOLUTION: This device adopts a normally open linear solenoid valve as a boosting valve, ABS control which is one set of decompressing control and linear boosting control is repeatedly executed. The device decides an initial value Pw0 of a W/C pressure estimating value Pw by considering vehicle body speed reducing speed at the time of starting first ABS control (namely, lock pressure) and brake operation time Tstp before ABS control starting. The W/C pressure estimating value Pw during ABS control is estimated on the basis of the value Pw0 and decompressing characteristics of a decompressing valve. The device uses an estimated value Pdiff of the differential pressure between the M/C pressure and the W/C pressure estimated by an expression Pdiff=(Pw0-Pw)+Pup1+Pup2, thereby deciding a command current value to the boosting valve during linear boosting control. Differential pressure additional values Pup1, Pup2 are set according to the time Tstp and increase of brake stepping during ABS control. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a vehicular brake fluid pressure control device for effectively restricting a pressure-increase delay when increasing wheel cylinder pressure in ABS control for performing linear pressure increase control by using a linear solenoid valve as a pressure increase valve. SOLUTION: This device using the normally opened linear solenoid valve as a pressure increase valve carries out the ABS control composed of one group of pressure reduction control, pressure holding control and special linear pressure increase control. In the special linear pressure increase control, quick pressure increase control is performed for a time T1, and succeedingly, gradual pressure increase control is performed. An instruction current value Id of the pressure increase valve is basically set at a value equal to a basic current value Idbase, and on the other hand, reduced by a value Ipr in relation to the Idbase during the quick pressure increase control. Furthermore, in the case that a change grade of the instruction current value Id in the quick pressure increase control is larger than a threshold value, the instruction current value Id is further reduced by a value Idown during a time from a starting point of the quick pressure increase control to a time TA. In this case, the instruction current control value Id is increased by a value Iup in relation to the value Idbase during a time from a starting point of the gradual pressure increase control to a time TB.

摘要翻译：解决问题的方案：提供一种车辆制动液压控制装置，用于在通过使用线性电磁阀作为增压阀进行线性增压控制的ABS控制中增加轮缸压力时有效地限制增压延迟。
解决方案：本装置采用常开线性电磁阀作为增压阀，执行由一组减压控制，压力控制和特殊线性增压控制组成的ABS控制。在特殊的线性增压控制中，对时间T1进行快速增压控制，接着进行逐渐增压控制。增压阀的指令电流值Id基本上设定为等于基本电流值Idbase的值，另一方面，在快速增压控制期间相对于Idbase减小Ipr值。此外，在快速增压控制中的指示电流值Id的变化等级大于阈值的情况下，指令电流值Id进一步减少从快速启动的起始点起的时间内的值Idown 压力增加控制到时间TA。在这种情况下，指令电流控制值Id在从逐渐增压控制的起始点到时间TB的时间内相对于值Idbase增加值Iup。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To properly estimate a differential pressure between a master cylinder pressure and a wheel cylinder pressure in ABS control of a high μ-side front wheel in an braking operation during traveling on a split road. SOLUTION: This device adopts a normally-opened linear electromagnetic valve as a boost valve, and repeats ABS control with a set of decompressive control/linear boost control. ABS control is executed to a first front wheel 1o by a brake operation on a "split road", and yaw-moment control is executed to a second front wheel hi. Under this condition, when brake fluid pressure control of the second front wheel hi is shifted to ABS control, this device calculates/updates a differential pressure estimated value Pdiffhi of the second front wheel hi used for deciding a command current value of the normally-open linear electromagnetic valve corresponding to the second front wheel hi using a relationship, "differential pressure of the second front wheel = differential pressure of the first front wheel - (wheel cylinder pressure of the second front wheel - wheel cylinder pressure of the first front wheel)".
