The invention provides a vehicle weight estimation method and device and a storage medium. The method comprises the steps of obtaining vehicle structure parameters; acquiring vehicle operation data at the effective stage that the vehicle speed is greater than zero and the driving torque is greater than zero; obtaining an ideal wind resistance coefficient and an ideal rolling resistance coefficient of the vehicle in the running process; and estimating the estimated weight of the vehicle according to the vehicle structure parameters, the vehicle operation data, the ideal wind resistance coefficient and the ideal rolling resistance coefficient. According to the method, the whole vehicle weight estimation can be realized under the condition of not increasing the hardware cost.
