Abstract
In an antiskid control device comprising detectors for measuring circumferential velocities of a plurality of wheels an actuator for operating a braking oil pressure for each of the wheels and an electric circuit for calculating friction coefficients on the road surfaces, to which the wheels are in contact, calculating aimed wheel circumferential velocities from the friction coefficients on the road surfaces and operating the actuator such that each of the aimed wheel circumferential velocities and each of the measured wheel circumferential velocities coincide with each other, the electrical circuit operates the actuator by setting individual aimed wheel circumferential velocities for the plurality of wheels from a vehicle deceleration calculated from an average value for the friction coefficients on the road surfaces with which a plurality of wheels are in contact, respectively, and the slip ratio for each of the plurality of wheels.
