Abstract
In an antilock brake device, a determining function of which the sign varies when a wheel slip ratio is identical to a target value, and a switching function comprising an integral term which is a time integral of the determining function, are set, and a brake torque target value is determined so that it is proportional to the switching function. Alternatively, the brake torque target value computed according to the determining function is corrected according to a wheel angular acceleration. In this way, a brake torque or the wheel slip ratio between a road surface and tires is precisely controlled.
