To stabilize a vehicle behavior by suppressing a slip of a primary drive wheel before the vehicle behavior changes greatly in a vehicle that has one of front wheel and rear wheel as the primary drive wheel and the other thereof as a secondary drive wheel.SOLUTION: A vehicle motion control method includes: calculating a first inner-outer wheel speed difference D1 being a difference in wheel speed between a right wheel and a left wheel, of a primary wheel of front and rear wheels (S1); determining whether the first inner-outer wheel speed difference is equal to or more than a first threshold (S2); and increasing, in the case of determining that the first inner-outer wheel speed difference is equal to or more than the first threshold, decreasing drive force of the primary drive wheel and increasing drive force of the secondary drive wheel, of the front and rear wheels (S3, S12).SELECTED DRAWING: Figure 6
【課題】前輪及び後輪の一方を主駆動輪とし他方を従駆動輪とする車両において、車両挙動が大きく変化する前に主駆動輪のスリップを抑制して車両挙動を安定化する。【解決手段】車両運動制御方法では、前後輪のうち主駆動輪の右輪の車輪速と左輪の車輪速との間の差分である第1内外輪車輪速差D1を算出し(S1)、第1内外輪車輪速差が第1閾値以上であるか否かを判定し(S2)、第1内外輪車輪速差が第1閾値以上であると判定した場合に、主駆動輪の駆動力を低減し、前後輪のうち従駆動輪の駆動力を増加する(S3、S12)。【選択図】図6
