The invention relates to a road slope estimation method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a first slope estimation value according to tire pressure information of a vehicle; acquiring a second slope estimation value according to the first acceleration and the second acceleration of the vehicle; the first acceleration is obtained through an acceleration sensor arranged on the vehicle; the second acceleration is obtained according to the running speed of the vehicle; obtaining a first weighting coefficient corresponding to the first slope estimation value according to the driving speed, the first acceleration and the second acceleration, and determining a second weighting coefficient corresponding to the second slope estimation value according to the first weighting coefficient; and according to the first weighting coefficient and the second weighting coefficient, performing weighted summation on the first slope estimation value and the second slope estimation value to obtain a target slope estimation value. By adopting the method, the accuracy of road slope estimation can be improved.
