An antilock brake control system for a vehicle including normally-opened solenoid valves, normally-closed solenoid valves, and diodes. Each of the normally-opened solenoid valves is switched over among a turned-on state in which a predetermined first electric current is permitted to flow through the coil, a turned-off state in which the supply of the electric current to the coil is topped, and a middle state in which a second electric current lower than the first electric current is permitted to flow. In addition, the system includes a switch that is maintained in an electrically disconnecting state during shifting of each of the normally-opened solenoid valves from the turned-on state to the middle state, until the shifting is completed.
