The invention discloses a road gradient estimation method and device, equipment, a storage medium and a program product, and relates to the technical field of vehicle control, and the disclosed road gradient estimation method comprises the steps that in the vehicle running process, the equivalent static acceleration of a vehicle at the current moment is obtained; according to the equivalent static acceleration, an initial road slope value of a road where the vehicle is located is obtained; determining an acceleration correction value according to the initial road slope value; correcting the equivalent static acceleration according to the acceleration correction value to obtain a target acceleration; and obtaining a slope estimation result of the road according to the target acceleration. The technical problem that the road slope estimation method is low in accuracy is solved, and the accuracy of the road slope estimation result is improved.
