The embodiment of the invention discloses a crawling control method and device, electronic equipment and a storage medium. The method comprises the steps that measured values of driving parameters of an electric vehicle in the driving process are obtained; obtaining an estimated value of the driving parameter according to the measured value of the driving parameter and the dynamic model of the gradient road surface; according to the estimated value of the driving parameter and a state observation model, obtaining an observed value of the driving parameter; and according to the measured value of the driving parameter, the estimated value of the driving parameter, the observed value of the driving parameter and the crawling working condition of the electric vehicle in the driving process, the approaching control value of the electric vehicle on the slope road surface is calculated. According to the technical scheme, the approaching control value of the electric vehicle on the slope road surface is finally obtained by obtaining the driving parameters of the electric vehicle and predicting the driving parameters, the stability of vehicle control is kept, and various different working conditions in the crawling process are dealt with.
