The present invention relates to a drive slip control method for a four-wheel distributed drive vehicle, comprising the steps of: detecting a driving force (Ft) acting on each wheel by a road surface of the four-wheel distributed drive vehicle and a wheel load (G) of each wheel, calculating an adhesion rate (r) from the driving force (Ft) and the wheel load (G), a slip rate (S) of each wheel of the vehicle is detected, an adhesion coefficient (mu1, mu2, mu3, mu4) of each wheel is calculated from the adhesion rate (r) and the slip rate (S), and if a first set of adhesion coefficients (mu1, mu2) of the wheels on the same side is greater than or less than a second set of adhesion coefficients (mu3, mu4) of the other wheels on the same side, the adhesion coefficients (mu1, mu2) of the wheels on the same side are determined to be greater than or less than the second set of adhesion coefficients (mu3, mu4) of the wheels on the same side. And if yes, judging that the road surface where the vehicle is located is a split road surface.
本发明涉及一种用于四轮分布式驱动车辆的驱动防滑控制方法,包括以下步骤:检测所述四轮分布式驱动车辆的路面作用在每个车轮上的驱动力(Ft)以及每个车轮的车轮载荷(G),根据所述驱动力(Ft)和所述车轮载荷(G)计算附着率(r),检测所述车辆的每个车轮的滑移率(S),根据所述附着率(r)和所述滑移率(S)计算每个车轮的附着系数(μ1、μ2、μ3、μ4),其中,如果同侧车轮的第一组附着系数(μ1、μ2)都大于或都小于另外的同侧车轮的第二组附着系数(μ3、μ4),则判断所述车辆所在的路面是对开路面。
