The invention provides a vehicle ramp estimation method, device and equipment and a readable storage medium, and the method comprises the steps that driving force, braking force, vehicle speed, first acceleration and second acceleration of a target vehicle are obtained, the first acceleration is longitudinal acceleration measured by a three-axis inertia sensor of the target vehicle, and the second acceleration is longitudinal acceleration measured by a three-axis inertia sensor of the target vehicle; the second acceleration is the speed change rate of the target vehicle; corrected acceleration is calculated according to the driving force, the braking force, the vehicle speed and the first acceleration of the target vehicle, and the corrected acceleration corrects errors caused by vehicle body pitching of the target vehicle relative to the first acceleration; and calculating ramp information according to the second acceleration, the corrected acceleration and the gravitational acceleration. According to the application, the error caused by the pitching of the vehicle body to the longitudinal acceleration measured by the three-axis inertia sensor is corrected according to the driving force, the braking force and the vehicle speed, and then the ramp information is calculated by combining the vehicle speed change rate and the gravitational acceleration, so that the error of the ramp information is reduced.
