Study on Driving Force Distribution and Power Consumption in Cornering


This paper clarifies the effect of direct yaw moment control on power consumption in steady state cornering. To accomplish this, cornering drag, mechanical loss, and electric loss were formulated from the standpoint of direct yaw moment. Then, the characteristics of cornering drag and power consumption were validated on an actual test vehicle. This paper also discusses the relationship between mechanical power of drive torque and power loss on contact patch of tire based on the formulated cornering drag and power consumption. Typical direct yaw moment controls are also compared in terms of power consumption.各輪独立したモータによる駆動力配分制御は,旋回時には操安性の向上だけでなく,走行抵抗を低減する効果がある.この低減メカニズムを定式化して,低減効果の大きい旋回条件を示すとともに,機械損失やモータの電気損失を考慮することで,旋回時における駆動力配分制御時の消費エネルギー特性を明らかにした.
