The invention discloses a road gradient estimation method, electronic equipment and a storage medium. The method comprises the following steps: acquiring vehicle motion parameters and acceleration sensor parameters; determining a first slope estimation value according to the vehicle motion parameters; determining a second slope estimation value according to the acceleration sensor parameters; calculating first error information in the vehicle motion parameters and second error information in acceleration sensor parameters; and determining an actual gradient value based on the first gradient estimation value, the second gradient estimation value, the first error information and the second error information. The slope estimation precision is improved by eliminating errors, and the reliability and accuracy of the slope estimation value are further improved by combining the estimation results of the two methods.
