PURPOSE:To prevent driving wheels from being idled by regulating a braking pressure on the bases of the detected results relating to the acceleration of speed of the driving wheels or the slippage between the speeds of the driving wheels and non-driving wheels. CONSTITUTION:Both engine revolution speed pulses from wheel speed sensors 16a-16d and an engine revolution pulse from the ignition 24 of an engine are input to a controlling circuit 17. Said circuit 17 calculates each speed of wheels according to a controlling program, accelerated or decelerated speed of driving wheels, and slippage between the speeds of the driving and the non-driving wheels. The signal from the circuit 17 activates a braking liquid reflux preventing actuator 18. If the pressure of the liquid is demanded to be increased, the actuator 18 operates pressure increasing actuator 19a or 19b and contrarily, if the pressure thereof is demanded to be decreased, the actuator 18 operates a pressure reducing actuator 20a or 20b. |
