Abstract
A filter arrangement of a vehicle includes a filter, preferably an active carbon filter, a sprung suspension for the vibrational mounting of the filter in the vehicle, a sensor unit for determining a variable corresponding to the current weight of the filter from a vibrational movement of the filter, and an analyzing unit for calculating a filling degree of the filter from the filter weight determined, taking the empty weight of the filter into account. The filter is suspended such that the filter can vibrate about a rotational axis fixed to the vehicle.
