The invention discloses a vehicle slip rate setting method and device, equipment and a storage medium, and relates to the technical field of automobile control, and the method comprises the steps that current driving parameters of a target vehicle are obtained, and the current slip rate and the current adhesion coefficient are obtained according to the current driving parameters; performing linear interpolation analysis on the current slip rate and the current adhesion coefficient based on preset test data to obtain a current reference slip rate; based on the current vehicle speed state, a target slip rate is obtained according to the current reference slip rate; according to the method, when the vehicle is driven, the real-time slip rate and the attachment coefficient are obtained according to the vehicle driving parameters, then the current optimal slip rate of the vehicle is obtained by performing current difference analysis on the current slip rate through the prediction data, the vehicle slip rate is adjusted in real time based on the optimal slip rate on the basis of the vehicle driving condition, the attachment utilization of tires is improved, and the vehicle driving safety is improved. The driving performance is improved, and the problem that the vehicle stability is poor and potential safety hazards exist due to the fact that the set vehicle slip rate does not conform to the actual vehicle driving condition is solved.
