ABSTRACT:
An automotive traction control system comprises a master cylinder, an external brake fluid pressure source, a brake fluid pressure control actuator being applied commonly to an acceleration-slip control and a deceleration-slip control, a first switching valve for establishing and blocking a communication between the master cylinder and the pressure control actuator, a second switching valve for establishing and blocking a communication between the external brake fluid pressure source and the pressure control actuator, and a control unit for deriving a pressure reducing control time necessary to reduce the wheel cylinder pressure to a designated brake fluid pressure, based on a pressure intensifying control time, during the acceleration-slip control. The control unit is arranged for switching the second switching valve just after the pressure reducing control time has elapsed, and for switching the first switching valve and a pressure intensifying valve and a pressure reducing valve both included in the pressure control actuator with a predetermined time lag after shifting of the second switching valve, in a transient state transiting from the acceleration-slip control mode to the normal braking operational mode.
