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.

Abstract: Anti-skid control apparatus includes wheel speed sensors for front and rear wheels. First and second fluid pressure control valve devices control brake fluid pressures of wheel cylinders of the front and rear wheels, arranged between fluid pressure generating chambers of a tandem master cylinder and the wheel cylinders respectively. A control unit receives outputs of the sensors for measuring or judging the skid conditions of the wheels and for generating instructions for controlling the valve devices. A valve apparatus generates fluid pressure in accordance with the lower one of the brake fluid pressures of the front wheels controlled with the valve devices arranged between the wheel cylinders of the front wheels and those of the rear wheels. When the wheel speed difference between the front and rear wheels on the same side of the road becomes larger than a predetermined value, or when the deceleration of the one rear wheel becomes larger than a predetermined deceleration for the one rear wheel which is smaller than a second predetermined deceleration for the one front wheel running on the same side as the one rear wheel, before the one front or rear wheel on the same side first generates a brake relieving signal, the control unit generates the instruction which controls the first or second fluid pressure control valve device for the same side so as to maintain the pressure constant, or to reduce the rising gradient of the pressure.

Abstract: A brake fluid pressure control apparatus for a vehicle includes a fluid pressure control valve device arranged between a master cylinder and a wheel cylinder, receiving control signals from a control unit measuring the skid condition of the wheel to control the brake fluid pressure to the wheel cylinder. A hydraulic reservoir stores the brake fluid discharged through the fluid pressure control valve device from the wheel cylinder and a pressure fluid supply conduit connects the master cylinder with the fluid pressure control valve device. A fluid pump returns the brake fluid from the hydraulic reservoir into the pressure fluid supply conduit and a valve apparatus is arranged in a conduit connecting the discharge side of the fluid pump with the master cylinder side, in the pressure fluid supply conduit. The valve apparatus takes a first position connecting both sides and a second position that cuts off the fluid flow from the discharging side of the fluid pump toward the master cylinder side. The valve apparatus is normally in the first position. During anti-skid control, it takes the first position continuously for a certain time depending on the control time of the fluid pressure decrease and continuously for another certain time depending on the control time if the fluid pressure is increased after the fluid pressure decrease, and it takes the second position continously for times other than the certain time and/or the other certain time. Alternatively, it cycles between the first and second position for a certain time depending on the control time of the fluid pressure decrease and/or for another certain time depending on the control time of increasing again the fluid pressure after the fluid pressure decrease, and it takes the second position for times other than the certain time and/or the another certain time.
