Abstract
A mechanically suspended vehicle has a travel measurement device (), a control unit () and an algorithm stored in the control unit (). The algorithm performs a method for determining an axle load. In a first test routine a level signal of a travel measurement device is acquired and evaluated, wherein, in a loading operation of the vehicle, a loading curve (F_i) is determined, and, in an unloading operation of the vehicle, an unloading curve (F_u) is determined. The values of the two curves are used to calculate an averaged load-travel characteristic curve (F_m) to be stored in the control unit. After each start of the vehicle, an axle load determination routine is repeated cyclically, and axle load values are continuously determined with the averaged load-travel characteristic curve (F_m). An axle load average value is calculated from the axle load values and displayed as the current axle load value.
