The invention relates to a road slope calculation method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining vehicle parameters which at least comprise the wheel speed of each wheel, the vehicle speed of the whole vehicle and the sensing acceleration of an acceleration sensor in the advancing direction; the method comprises the following steps: acquiring a wheel acceleration maximum value, a wheel acceleration minimum value and a whole vehicle acceleration, judging a sensing limited state of the vehicle according to the sensing acceleration and the wheel acceleration maximum value, determining an original slope value of the vehicle in the sensing limited state, and determining a first slope output value of the vehicle according to the original slope value and a first slope output value of the previous moment. And weighting to obtain a second gradient output value at the current moment so as to control the vehicle based on the second gradient output value. By adopting the method provided by the invention, the problem of inaccurate slope estimation in the prior art can be improved.
