The invention relates to a non-standard road surface-oriented vehicle optimal slip rate prediction method, which comprises the following steps that: through a first formula and a second formula, the current slip rate and the current utilization adhesion coefficient of a vehicle are respectively determined, and the utilization adhesion coefficient is used for representing the utilization degree of the vehicle on the adhesion coefficient between wheels and the ground; the slip rate and the utilization adhesion coefficient have a corresponding relation; based on the current utilization adhesion coefficient, calculating through a first equation to obtain a first predicted optimal slip rate of the vehicle; determining a second predicted optimal slip rate according to an extreme point of the second equation; and determining the current optimal slip rate of the vehicle according to the first predicted optimal slip rate and the second predicted optimal slip rate. The problem that an existing optimal slip rate calculation method has certain hysteresis quality and is difficult to provide support for real-time control is solved.
