Abstract

PURPOSE: To effectively control antiskid, by using hydraulic pressure characteristics of two kinds for braking for a high μ road surface and a low μ road surface, and by changing over both characteristics.
CONSTITUTION: The signals of frequency proportional to the number of revolution of a wheel detected by means of a wheel tevolution number sensor 3 are converted into voltage value ωFV proportional to the speed of revolution of the wheel by means of a frequency voltage converting corcuit 8 under a condition that braking is applied. Voltage value ωFV proportional to the adjustable acceleration of the wheel is obtained by differentiating the voltage value ωFV by means of a differentiation circuit 9. Comparison circuits 23, 24 put out ON signals for altering hydraulic pressure characteristics for a low μ road surface or hydraulic pressure characteristics for a high μ road surface when voltage value ωFV memorized becomes lower than value experimentally decided or higer than the value.
