The invention relates to the technical field of vehicle auxiliary driving, and provides a vehicle mass estimation method and device and a vehicle, and the vehicle mass estimation method comprises the steps: obtaining the current whole vehicle working parameters of the vehicle in the driving process; according to the current whole vehicle working parameters, whether the current driving working condition of the vehicle is matched with a preset vehicle fluctuation working condition set or not is recognized; when it is determined that the current driving working condition is not matched with each vehicle working condition in the vehicle fluctuation working condition set, vehicle mass corresponding to the current whole vehicle working parameters is estimated based on a preset vehicle longitudinal dynamics model; the vehicle longitudinal dynamics model defines the relation between the vehicle mass of the vehicle and the whole vehicle working parameters. Therefore, the working parameter signals are screened, filtered and removed under the working conditions of low vehicle speed, turning, ABS triggering, vehicle braking, gear shifting and other low algorithm precision, it is guaranteed that the model outputs a more accurate estimated value, and the reliability and precision of the predicted vehicle quality are improved.
