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 a brake system capable of suppressing decrease in braking force during ABS control.
SOLUTION: During an ABS control mode, the brake system corrects the target slip rate in accordance with the turning, and determines whether the vehicle is running on a poor surface road. If the vehicle is running on a poor surface road, the system sets a target slip rate that provides a greater longitudinal force than the aforementioned target slip rate.

摘要： PROBLEM TO BE SOLVED: To provide a brake control device capable of performing proper brake control for drive wheels connected to each other through a differential gear.
SOLUTION: This brake control device performs the brake control to a plurality of wheels to which a drive force is distributedly transmitted through the differential gear by decreasing, holding, or increasing brake fluid pressure according to the accelerations of the wheels. The device comprises a mis-decompression suppressing means to lower a decompression reference value for reducing braking force when the wheel accelerations of the wheels exceed prescribed values. When the circulation of torque by the other wheels connected to each other through the differential gear are above prescribed limits, the lowering of the decompression reference value by the mis-decompression suppressing means is prohibited (S200, S204).

摘要： PROBLEM TO BE SOLVED: To provide a braking system capable of quickly discriminating a road condition, when a vehicle moves from crossroads to a constant road.
SOLUTION: In an ABS control mode, a period, from when a liquid pressure in each wheel starts to decrease, then turns to increase until when the liquid pressure restarts to decrease, is made to be one control cycle. ECU10 resets the integrated value of pressure increase/decrease hour of the liquid pressure of one wheel cylinder H

FR at every control cycle in the ABS mode. When the integrated value of the liquid pressure of either the left or right wheel cylinder H
FL , H
FR is reset, incorrect decision is restrained, even when a vehicle moves from a crossroads to a constant road, enabling rapid determination of the road condition, since the integrated value in a plurality of control cycles are not accumulated.

摘要： PROBLEM TO BE SOLVED: To provide a braking system capable of improving vehicle turning performance during ABS control.
SOLUTION: When a difference not lower than a predetermined value occurs between a target yaw rate and a real yaw rate, controlling a target slip ratio to be always within a μ peak region does not provide a sufficient lateral force or sufficient turning performance. When the target slip ratio in the normal ABS control mode is changed to the lateral force emphasizing side, namely when a μ peak holding control state having the target slip ratio within the μ peak region is changed in the decreasing direction of the target slip ratio, the sufficient lateral force is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a braking force control system capable of suppressing a detection error of a vehicle velocity.SOLUTION: A control unit that controls a braking force on the basis of a vehicle velocity calculated from a wheel speed is included. When a wheel speed of a predetermined driving wheel that is a driving wheel whose wheel speed is the highest tends to increase and a wheel speed of three wheels other than the predetermined driving wheel tends to decrease (S10-Y), the vehicle velocity is calculated with the wheel speed of the predetermined driving wheel excluded (S40). When the vehicle velocity is calculated with the wheel speed of the predetermined wheel excluded (S10-Y and S20-Y), a maximum value of a wheel speed of a rolling wheel may be adopted as the vehicle velocity.
