N2  - We propose the new vehicle dynamics control of in-wheel electric vehicle based on the tire force usage rate. In the vehicle dynamics control, we have adopted non-linear optimizing controller using the direct yaw-moment control, the tire force usage rate and the tire force. Because it has been that DYC is not compatible with the tire force usage equalization and it is important to consider total tire force Fx and Fy as feedback signals for being compatible DYC with the tire force usage equalization. It was found that our control logic devised in the simulation. In this report, an attempt has been made to clarify whether our control logic is effective as predicted by simulation or not for real vehicle by conducting real electric vehicle test run. Our control logic was also found to be effective enough in the improvement of driving stability compared with the other type of DYC. From the experiment result, it has been found that our control logic is very effective for the independent in-wheel motor electric vehicle. Because the electric vehicle handling has become neutral steering by using our control logic, and consequently, the vehicle could be neutrally steer up to higher speed than without control and the other type of DYC.<p />  <p>Language: ja</p>
