Abstract: In an anti-ski control apparatus for a vehicle braking system including fluid pressure control valve devices and a valve apparatus, when brake-relieving output signals are obtained from both rear wheels, the brake-relieving output signal of the one of the rear wheels that is obtained later than that of the other is combined logically with the brake-relieving output signal of the one of the front wheels running on the same side as the one rear wheels to form a brake-relieving control signal for controlling a first or second fluid pressure control valve device connected to the wheel cylinder of the one front wheel. A brake-increasing control signal is generated by the first or second fluid pressure control valve device after the brake-relieving control signal disappears based on the brake-increasing output signal of the one of the front and rear wheels on the same side which has a stronger locking tendency than the other. In the alternative, the signal is formed based on the brake-increasing output signal of the one of the front and rear wheels on the same side, the acceleration of which is smaller than that of the other. A brake-holding control signal by the first or second fluid pressure control valve device, before the brake-relieving control signal generates, is formed by logical sum (OR) of the brake-holding output signals of the one front and rear wheels on the same side, and a brake-increasing control signal by the first or second fluid pressure control valve device, after the brake-relieving control signal disappears, is formed on the basis of the brake-increasing output signal of the one of the one front and rear wheels on the same side the brake-holding output signal of which has generated sooner than that of the other.

The valve apparatus includes a casing having first and second input ports, an output port, a piston, a control chamber and a volume chamber formed at both sides of the piston. A valve part is disposed between the first input port and the volume chamber, the first input port being connected to one fluid pressure generating chamber of the master cylinder and the output port being connected to the wheel cylinders that are connected to the other of the two brake conduit circuits. A changeover valve is connected to the second input port. The changeover valve is set either in a first position for connecting another fluid pressure generating chamber of the master cylinder to the control chamber or else a second position for connecting the output side of the fluid pressure control valve with the control chamber. When the changeover valve is in the first position, the valve part is open, and when the changeover valve is in the second position and the fluid pressure control valve is operated, the piston is moved toward the control chamber to close the valve part so as to cut off the first input port from the volume chamber and change the volume of the volume chamber.

Abstract: 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.
