ABSTRACT:
An antilock brake control system in a vehicle includes a PID calculating device for carrying out a PID calculation based on a deviation between a target slip rate determined based on a presumed vehicle speed and a slip rate, so that the operation of braking fluid pressure regulating device is controlled based on the result of the calculation in the PID calculating device. In the antilock brake control system, a braking pressure control mode is decided based on the result of comparison of a PID calculation value calculated in the PID calculating device with a predetermined threshold value, so that the operation of braking fluid pressure regulating device is controlled in such control mode. When the amount of variation in PID calculation value within a predetermined time exceeds a predetermined value, a control mode different from a control mode decided from a current PID calculation value is selected. Thus, the occurrence of an excessive control and a control delay can be prevented and moreover, the control of the braking pressure can be performed in a simple structure enabling the use of an inexpensive on-off operated solenoid valve.
