We propose new vehicle dynamics management of in-wheel electric motor vehicle based on tire force usage rate. In the vehicle dynamics management, we adopted non-linear optimizing controller using direct yaw-moment control, tire force usage rate and each tire force. In cornering performance test simulation of 3 degree freedom model, we confirmed that by using this vehicle dynamics management, saturating tire force could be avoided and higher critical speed also could be achieved. We also conducted pylon course slalom test simulation. By this simulation, it was confirmed that the 4 wheel drive in-wheel motor electric vehicle with the proposed vehicle dynamics management system could have higher stability performance comparing to the same vehicle without control.
