Abstract

PURPOSE:To improve braking performance by detecting a too little slipping condition in a wheel-lock recovering process at the time of braking and, at the time of executing small pressurization with a small pressure increasing rate of a braking pressure, correcting its pressurizing time in accordance with the pressurizing time of the last time small pressurization. CONSTITUTION:In a wheel speed control device 1, each wheel speed is operated 11 based on each wheel speed sensor 2i and a vehicle speed is obtained by differentiating 13 the wheel speed. Also, by operating 14 the slip speed of each wheel from the wheel speed and vehicle speed, a defined control variable is operated by a controller 15 from the slip speed and vehicle speed to control a brake pressure controlling actuator 3. Further, the overs and shorts of slip speed after lock-recovering is integrally operated by a controller 16 based on the slip speed, to command the execution of small pressurization with a small pressure increasing rate. In this case, the applying time of small pressurization is determined by correcting the executing time of the previous application of small pressurization, at the time of judging the execution of the small pressurization.
