Title:
ANTISKID CONTROLLING METHOD
Document Type and Number:
Japanese Patent JPS62152957
Kind Code:
A
Abstract:
PURPOSE:To prevent a wheel from getting an early lock, by making a controller continue decompression till the specified condition is satisfied when duration from a point of time that a wheel speed reaches the lower side of the reference speed in two reference speeds during decompression to that point of decompression completion. CONSTITUTION:The speediest wheel velocity among wheel velocities Vw1-Vw4 to be found by speed counting circuits 5-8 on the basis of each output out of speed sensors 1-4 detecting a wheel velocity of each wheel at right and left and front and rear is selected by a select circuit 13, and the selected wheel velocity is passed through a filter 14 whereby the pseudo-body velocity Vv is set up. And, both first and second reference velocities VT1 and VT2 being followed to this Vv with each of constant low speed differences are set by a setting circuit 15. And, after the wheel velocity during deceleration reaches the VT1 and reaches the VT2, when time of up to that point of decompression completion becomes more than the specified time, the decompression of braking hydraulic pressure is made so as to be continued till the wheel velocity is restored to the VT1.
