摘要： PURPOSE:To prevent deficiency of pressure P beforehand by driving a fluid pump when the pressure P of an accumulator is smaller, and detecting consumption conditions under which the pressure P is consumed before it becomes smaller than a specified level, thereby driving the pump. CONSTITUTION:In a device wherein pressure fluid discharged from a fluid pump A is once stored in an accumulator B and thereafter it is supplied to a brake unit D through a control valve means C, a pressure detecting means E for detecting the pressure of accumulator B, and the output signal is input to first and second drive control means F, G. A first drive signal is output from the means F to drive the pump A when the detected pressure is lower than the specified level. A second drive signal is output to drive the pump A after consumption conditions under which the pressure of accumulator is consumed are detected.

摘要： PURPOSE:To contrive compatibility of steering performance and braking performance at the time of braking a vehicle turned. CONSTITUTION:A device comprises wheel speed sensors 101 to 104, G sensor 110, steering angle sensor 130 and an ABS computer 120, and the ABS computer 120 calculates each wheel speed and a car body speed from detection signals of the wheel speed sensors 101 to 120 and calculates an ordinary target control car speed VSN when a vehicle is placed in a straight advancing condition based on both the wheel and car body speeds. Simultaneously with the above, based on a steering angular speed calculated from a detection signal of the steering angle sensor 130, when quick steering is decided to be performed, the ordinary target control car speed VSN is corrected in a direction of increasing by a quick steering correction amount DELTAK, and also this quick steering correction amount DELTASK is changed in accordance with a road surface mu decided from a detection value of the G sensor 110.

摘要： PURPOSE: To provide an anti-skid device capable of having the same function as that of a conventional anti-skid device having two actuators, by providing one actuator and a low-priced modulating valve of special construction in an anti- skid control.
CONSTITUTION: An anti-skid device comprises an actuator 30 disposed in a hydraulic circuit (a) communicated with a rear brake mechanism 12 of a hydraulic circuit A of a first system and a modulating valve 40 disposed in a hydraulic circuit (b) communicated with a rear brake mechanism 15 of a hydrulic circuit B of a second system. The actuator 30 is arranged to control hydraulic pressure in a hydraulic circuit a
1 , while the modulating value 40 comprises, in the housing 41 thereof, a balancing piston 42, a check valve 43 and a switching valve 44 which is so constructed that opens a bypass passage P
2 by being pushed under pressure from the hydraulic circuit B in case of failure of the hydraulic circuit A.
