    摘要： A method, an apparatus and a computer program product for estimating the current load of a vehicle wherein a filter bank including a filter for different weight classes, each filter implementing a vehicle model for estimating the current mass of the vehicle. Based on vehicle data indicative of a current driving situation of the vehicle, and filter parameter specific for the respective weight class, each filter provides a load estimation value as filter specific estimation of the current load of the vehicle.

    摘要： The present disclosure relates to the estimation of a velocity of a first object using accelerometer signals, indicating an acceleration of the first object and/or a second object coupled to a first object. To this end, a characteristic frequency in the accelerometer signal spectrum may be determined, preferably by applying a parametric model or by performing a spectrum analysis, and used as a basis to estimate the velocity of the first object based on the determined characteristic frequency. The characteristic frequency may be determined by identifying the frequency having the maximum spectral amplitude or by identifying the fundamental frequency or a particular harmonic in the spectrum.
