摘要： A method of controlling the brake pressure in an anti-lock vehicle braking system provides for determining the deviation of a control magnitude, such as the slip or retardation of a wheel, from a given rated value Sw in the course of a control cycle. A threshold value which is decisive for the pressure decrease at a wheel subject to the risk of becoming locked is changed for the next successive control cycle in response to the amount of the deviation of the control magnitude from the rated value.

摘要： An anti-skid control apparatus for a vehicle includes fluid pressure control valve devices arranged between a tandem master cylinder and the front wheels of the vehicle, and a control unit receiving outputs of wheel speed sensors to assess skid conditions of the wheels and to control the valve devices. The apparatus discriminates between "low side" and "high side" of the road by assessing skid conditions of either the rear wheels or the front wheels. The braking pressure of the rear or front wheel that is on the low side and that of the wheel connected diagonally to it are controlled in either a "select-high" or a "select-low" manner, and the pressures of the other diagonally opposite wheels are controlled in the opposite manner. In the alternative, the apparatus may assess the skid condition of the one rear wheel based on the larger of the braking frictional coefficients of the sides of the road, on the basis of the acceleration and slip conditions of the one rear wheel, while it judges the skid condition of the other rear wheel on the smaller one of the braking frictional coefficients of the sides of the road only on the basis of the acceleration condition of the other rear wheel, and the braking pressures of the respective conduit systems are controlled in the select-low manner.

摘要： In an anti-lock vehicle braking system the brake pressure acting at the controlled wheel is controlled in such a manner that the threshold value with respect to the rotational retardation of the wheel at the beginning of a lowering or raising of pressure is increased briefly, during a control cycle, by a constant amount (S.sub.H -S.sub.G) with respect to a threshold base value (S.sub.G) in order to avoid any undesired control operations caused especially by axle vibrations, pot holes, and the like. The threshold value is then decreased in response to the period of time of the pressure reduction in the preceding control cycle. The decreasing of the threshold value is carried on to values S.sub.T below the threshold base value and maintained for a given time interval (t.sub.x -t.sub.y).

摘要： An anti-skid brake control system detects braking condition on at least two wheels for detecting synchronous braking condition in the wheels. Increasing of braking fluid pressure in one wheel cylinder associated with one of the wheels is delayed with respect to the brake fluid pressure increasing timing of the other wheel cylinder associated with the other wheel. By delaying increasing of the braking pressure, the braking fluid pressure in one of the wheel cylinder is maintained lower than that in the other. Therefore, when one of the wheel, for which higher braking pressure is applied through the associated wheel cylinder, the other wheel is maintained at non-locking state. Therefore, the wheel speed closely reflects the actual vehicle speed. This assures acurate brake control in the anti-skid brake control for the automotive vehicle utilizing the vehicle speed representing value derived based on the rotation speed of non-locking wheel.

摘要： An anti-skid control system for motor vehicles is provided wherein when the time period from when the wheel velocity being decreased reaches a second reference velocity to a low peak of the wheel velocity at which the reduction of the brake pressure is to be stopped, is longer than a predetermined time period, the reduction of the brake pressure is continued until the wheel velocity is increased up to a first reference velocity which is higher than the second reference velocity. In this way, even if the wheel velocity drops sharply because the coefficient of friction of the road surface suddenly changes from high to low, the wheel velocity recovers so that the wheels of the motor vehicle are prevented from locking early.

摘要： Wheel speed (V.sub.R) and braking pressure (P.sub.B) applied to a wheel are continuously measured and utilized to estimated values from a mathematical system model, to obtain the physical values: coefficient of friction (.mu.), vehicle speed (V.sub.F), slope of a slip curve (d.mu./dS), slip (S), and coefficient of friction of a stationary-rotary brake couple structure. At least one of the physical values so obtained, and preferably the coefficient of friction (.mu.), vehicle speed, and slope of wheel slip curve are used to control braking pressure being applied to the wheel. Braking pressure can be controlled for example for braking in accordance with coefficient of friction and slope of the friction-slip curve, for example to operate the wheel just before the coefficient of friction drops as the wheel begins to slip. Spinning of a wheel can be avoided by controlling the braking pressure to be below slippage value.
