Abstract (en)

[origin: EP0712770A2] An antiskid control device (K1-K5) which calculates an estimated fluid pressure (PTi) of each of wheel cylinders (2A-2D) under antiskid control in each control cycle so as to adjust a fluid pressure of each of the wheel cylinders (2A-2D) on the basis of the estimated fluid pressure (PTi) and behaviors of wheels, comprising: a differential pressure detecting member which detects a difference between a fluid pressure of a master cylinder (1) and the fluid pressure of each of the wheel cylinders (2A-2D) so as to produce an output signal indicative of the difference between the fluid pressure of the master cylinder (1) and the fluid pressure of each of the wheel cylinders (2A-2D); wherein when on the basis of the output signal of the differential pressure detecting member (SS, SSW, PSWi, SPSi), the difference between the fluid pressure of the master cylinder (1) and the fluid pressure of each of the wheel cylinders (2A-2D) is found to be in the vicinity of zero, the estimated fluid pressure (PTi) of each of the wheel cylinders (2A-2D) is set to a predetermined value (PTmax) by stopping addition in calculation of the estimated fluid pressure (PTi). <IMAGE>
