Abstract
A method of controlling the braking behavior of various wheels of a vehicle during a normal braking mode of operation and during an antilock braking mode of operation, the method using a control unit which calculates various parameters over a known time increment (t-t.sub.1) the method including the steps of: obtaining a value of the actual rotational velocity of each wheel (W.sub.1,W.sub.2); generating a first signal indicative of braking effort P(in) or desired vehicle deceleration; generating a per wheel velocity command signal the slope or deceleration of which is proportional to the desired vehicle deceleration p(in) and a multiplicative scale factor (ABSG.sub.i +G.sub.I) for adjusting such deceleration during the normal braking mode and antilock braking mode, generating a per wheel error signal Ei as a difference between the wheel velocity command and actual rotational velocity of each wheel; operating upon the error signal Ei to generate a brake activity command signal B.sub.i, regulating brake force in response to the brake activity command signal B.sub.i.
