A method for determining an axle load and a suspension system are configured for a vehicle having at least one leaf spring connected at its ends in spring holders of a vehicle body and connected in its central region to a chassis of the vehicle. The following steps are performed: measuring a measurement distance of the vehicle body relative to the chassis; determining whether there is currently a loading or unloading process of the vehicle, determining a relevant hysteresis curve of a pre-stored hysteresis field depending on the determination of a loading or unloading process, and determining a current axle load projection value from the measurement distance and the relevant hysteresis curve. A loading process criterion and an unloading process criterion may be considered. The determined axle load projection value thus serves as a projected or estimated axle load. Furthermore, the hysteresis field can be updated.
