PROBLEM TO BE SOLVED: To secure responsiveness required for pressure reduction of an ABS control. SOLUTION: When a slip ratio is higher than a first threshold value Th1 and a slip ratio decreasing gradient is higher than a second threshold value Th2, current to first to fourth linear valves SLFR, SLRL, SLFL and SLRR is made OFF, and current is not made to completely flow. As a result, pressure reduction of actual W/C pressure can be prevented from being gently performed due to the influence of fine current to secure responsiveness required for pressure reduction.
