PROBLEM TO BE SOLVED: To improve small turning performance by providing a braking force control means for generating a braking force in a rear side turning inner wheel with respect to an advancing direction based on a steering direction detected by a steering angle detecting means. SOLUTION: When a braking force is generated in a rear side turning inner wheel with respect to an advancing direction, the turning radius of the outermost part of a car body at the time of turning is reduced, and thus small turning performance is improved. For advance quarry control, a brake fluid is supplied to the wheel cylinder 44RR of a right rear wheel RR. For a normal state, an ECU turns ON an STR 26, an SA-3 54 and an SRLR 70. Thus, a high-pressure brake fluid accumulated in an accumulator 20 is supplied through a high-pressure passage 22, the STR 26, the SA-3 54, an SRRH 68 and a pressure adjusting hydraulic passage 72 to the wheel cylinder 44RR, and thereby a braking force is generated in the right rear wheel RR. Thus, small turning performance during advance quarry control is improved. |
