PURPOSE:To make antiskid control commensurate to an accelerating slip regardless of the slip, by controlling increase or decrease in brake fluid pressure on the basis of th presence of the acceleration slip, estimated speed, rotational frequency, etc., in a brake operating state. CONSTITUTION:An antiskid controller judges the presence of an accelerating slip with a controlling device controlling increase or decrease in brake fluid pressure upon comparing rotational frequency between front and rear wheels, and calculates the estimated speed of a car from the rotational frequency, while on the basis of the presence of the accelerating slip, the estimated speed, rotational frequency and acceleration or deceleration of the rotational frequency in a brake operating state, it judges whether increase or decrease in the brake fluid is necessary or not, thus the increase or decrease in the brake fluid is controlled on the basis of this judgment result. In any case that there is the accelerating slip or not, the antiskid control commensurate to that takes place and what is more, the actions of a car by the antiskid control comes to yet more stable. |
