A Theoretical Consideration to Vehicle Behavior by Direct Yaw Moment Control to Zero Vehicle Slip Angle at Any Location of Vehicle

任意の位置の横すべり角零化 DYC 制御時の車両運動についての理論的考察

Firstly, this paper studies a Direct Yaw Control (DYC) to reduce spin tendency. To reduce load rate of rear tires, a DYC control law to zero cornering force of rear wheels is formulated. Further vehicle response with this control is obtained. This vehicle response is first order delay system. Its time constant value is similar to the time constant with active rear steer control to zero vehicle slip angle at C.G. Since to zero cornering force of rear wheels is equivalent to zero vehicle slip angle at rear wheels, the relation of the position whose vehicle slip angle is zeroed and vehicle's behavior is also considered.タイヤ負荷率の小さい領域におけるESC のアンチスピン制御の設計指針をえるために,この領域のヨーモーメント制御について考察した.まず後輪負荷率が0 である完全アンチスピン制御を考察し,その制御限界を指摘する.つぎにその限界を拡大するために,完全ではないアンチスピン制御として後輪負荷率低減制御を考察した.以上の結果から,制御則の基本的指針を得た.
