Abstract
An antiskid control device for vehicles, comprising a timer circuit for producing a timing signal in synchronism with the extinction of a release signal for a skid control, apparatus for rapidly increasing the braking pressure applied to the wheel in response to said timing signal coming from the timer circuit, and correcting apparatus for increasing the braking pressure increasing rate when a large amount of friction is present between the wheel and the road surface, said antiskid control device being able to hold the fluctuation of the braking pressure within a narrow range to prevent unnecessary vibrations of the vehicle at the time of braking due to the fact that the braking pressure increasing rate is changed when the braking pressure is reapplied to the wheel, and being able to control the braking operation at all times in a manner best suited to the various road surface conditions encountered so that a skid of the vehicle is prevented from occurring and the braking distance is reduced greatly, due to the fact that the braking pressure increasing rate is adjusted in accordance with the coefficients of friction between the wheel and the road surface.
