PURPOSE:To improve the stability at the time of turning by regulating the brake liquid pressure to be constant to the left and right drive wheels based on a slippage rate of the left and right drive wheels when a yaw rate of more than a predetermined value is detected by a yaw rate detecting means for a brake controlling means. CONSTITUTION:A traction controlling means performs a control of a left and right integrated control type in which the brake liquid pressures for the left and right rear wheels are increased when a yaw rate of more than a predetermined value is detected by a yaw rate senser 74 and if a slippage rate SRL or SRR for one rear wheel 1RL or 1RR reaches a desired slippage rate SB for reducing the slippage rate for the rear wheel to be less than the desired slippage rate. The drive force for the left and right rear wheels 1RL, 1RR are thus reduced constantly when the vehicle is turning, so a differential drive force is not generated between the left and right drive wheels, and slippage at the rear wheel is restricted, thereby the stability of the vehicle can be secured at the time of turning. |
