PURPOSE:To prevent the lowering of driving and braking performance by setting driving torque suppressing control in the control sensitivity lowered state including the inhibition of execution. CONSTITUTION:At the time of traction control, a control means 12 performs change over control on the magnetization-demagnetization of inflow-outflow solenoid valves 4, 5 corresponding to driving wheel brake devices BFL, BFR and traction controlling normally opened and normally-closed type solenoid valves 6, 7. A control part 19 judges slip tendency by comparing the driving wheel speed with high-speed side and low-speed side reference speeds VRH, VRL as well as discriminates the accelerating-decelerating state of a body from the body speed VR estimated by a body speed estimating part 16 and the driven wheel speed Vw, and in case of deceleration, sets driving torque suppressing control in the control sensitivity lowered state including the inhibition of execution. Driving and braking performance can be thus prevented from being lowered.
