Abstract
A brake control device in an antilock brake system is disclosed for automatically adjusting a valve according to a wheel brake locking symptom to reduce a fluid pressure in a brake cylinder and eliminating symptom of brake locking. The brake control device includes a microcomputer which has a step for outputting a pressure reduction signal K required to eliminate a locking symptom, and a detector for detecting a current brake cylinder pressure. The microcomputer further has a step for correcting the pressure reduction signal K based on the current brake cylinder pressure. Thus, a corrected pressure reduction signal K is used for reducing the brake cylinder pressure.
