摘要： The invention is directed to an anti-skid control system for controlling braking forces applied to road wheels with hydraulic braking pressure supplied from a master cylinder to wheel brake cylinders and controlled in response to braking condition of the road wheels. A wheel speed of at least one of the road wheels is detected to provide an output signal corresponding to the wheel speed. A hydraulic braking pressure supplied to each of the wheel brake cylinders is increased, held or decreased in response to a variation of the wheel speed. The hydraulic braking pressure supplied to each of the wheel brake cylinders is increased in response to a proportion between an increasing time for increasing the pressure and a holding time for holding the pressure. The increasing time provided for one of at least two wheel brake cylinders is prohibited from being coincident with the increasing time provided for the other. Thus, the timing for increasing the hydraulic braking pressure in one of the wheel brake cylinders will not coincide with that in the other.

摘要： An anti-skid controlling apparatus which establishes the time allocation for the pressure decreasing time and decreased pressure holding time, as well as the time allocation for the pressure increasing time and increased pressure holding time, in accordance with the correlation between wheel acceleration and wheel lock level. The brake fluid pressure in the wheel cylinder is increased, held constant or decreased as needed. This makes it possible to establish optimal time allocation settings allowing for the pressure increasing and decreasing characteristics of the pressure controlling device. In turn, brake fluid pressure control is kept optimally provided independent of various factors that would affect the brake fluid pressure in the wheel cylinder. Thus the apparatus is suitable for use on board diverse kinds of vehicle with diverse characteristics.

摘要： The invention is directed to an anti-skid control system for controlling a braking force applied to each of the road wheels with a hydraulic braking pressure supplied to a wheel brake cylinder through pressure control means. A wheel speed of each of the road wheels is detected. Then, an estimated vehicle speed for each of the road wheels is calculated on the basis of the wheel speed and a decreasing rate of estimated vehicle speed for at least one of the road wheels other than the road wheel for which the estimated vehicle speed is being calculated. The estimated vehicle speed is, therefore, prevented from being set largely below the actual speed of the vehicle. The pressure control means is provided for increasing, holding or decreasing the hydraulic braking pressure in response to a result of comparison between the estimated vehicle speed and the wheel speed for each of the road wheels.

摘要： The invention is directed to an arrangement for controlling a braking force applied to each of right and left road wheels individually depending upon a braking condition, with a hydraulic braking pressure supplied to each of wheel brake cylinders through actuators respectively. The actuators are controlled by the braking force control system wherein output signals of wheel speed detectors are fed into first and second detecting circuits respectively by which the braking conditions of the road wheels are detected. Then, the detected signals are fed into a first driving circuit which produces driving signals fed to the actuators on the basis of an output signal fed from either of the detectors for one road wheel having a tendency to be locked first. One of the actuators provided for the road wheel on the road surface of the lower coefficient of friction is driven by a driving signal fed from the first driving circuit, whereas the other actuator is driven by a driving signal which is fed from the first driving circuit and modified thereafter by the second driving circuit in response to a value representing a vehicle speed so as to increase the hydraulic braking pressure rapidly when the vehicle is driven at low speed, consequently shortening the stopping distance.

摘要： An anti-skid control system for an automotive vehicle is provided with an actuator which is disposed in a hydraulic circuit between a pressure generator and a wheel brake cylinder. The actuator is arranged to control the hydraulic braking pressure applied to the wheel brake cylinder. In response to a wheel speed detected by a wheel speed detector, it is determined in an electronic control unit whether a condition for decreasing the braking pressure is effected. When this condition is effected, the decrease mode is provided in the control unit. When a predetermined period of time lapses after the decrease mode is initiated, the decrease mode is turned to a pressure control mode for applying the braking pressure to prevent the road wheel from being locked. When the condition is not effected during the predetermined period of time after the decrease mode is initiated, the decrease mode is turned to a direct supply mode for directly communicating the pressure generator with the wheel brake cylinder. Consequently, the lack of braking force caused by the delay of timing for decreasing the hydraulic braking pressure due to an erroneous detection of a locking condition of the road wheel on a rough road is effectively prevented.

摘要： The invention is directed to an anti-skid control system for controlling a braking force applied to a road wheel with a hydraulic braking pressure supplied to a wheel brake cylinder through a pressure control valve controlled by an electronic controller. On the basis of a wheel speed of the road wheel detected by a wheel speed sensor, the controller calculates an estimated vehicle speed and sets a reference speed on the basis thereof. In the controller, the wheel speed is compared with the reference speed, and in response to a result of comparison the hydraulic pressure supplied to the wheel brake cylinder is controlled by the pressure control valve. Through an adjustment by the controller, the hydraulic braking pressure is decreased in response to a change of difference between the wheel speed and the estimated vehicle speed for a certain period of time. The controller may be arranged to calculate an integrated value of the difference between the wheel speed and the estimated vehicle speed, to compare a value which is obtained by subtracting the integrated value from the wheel speed, with the reference speed, and to decrease the hydraulic pressure in the wheel brake cylinder in response to the result of comparison.
