It has been shown in our previous report that DYC is not compatible with the tire force usage equalization and it is important to consider total tire force F_x and F_y as feedback signals for DYC being compatible with the tire force usage equalization. Also, the control logic devised then has been found very effective in the electric vehicle run test. However, the vehicle dynamics control of a general car is controlled by the hydraulic brake system. In this report, our control logic is applied the hydraulic brake system of the electric vehicle, and an attempt has been made to clarify whether our control logic is effective or not for real vehicle by conducting real electric vehicle braking turn tests. According to the electric vehicle braking turn tests, the tire force usage rate has been not saturated by our control logic, and our control logic has improved the driving stability more than ABS of special condition and other DYC. It has been found that our control logic is very effective for braking turn of the independent wheel-in motor electric vehicle. Also, handling has become neutral steering by using our control logic at braking turn.
