Summary:The physical and/or mental condition of a vehicle occupant can be recognized on the basis of a BCG (ballistocardiograph) signal, which is obtained by means of a BCG sensor. The BCG sensor is an MEM sensor; a cross-correlation of the BCG signal with heartbeat parameters is carried out in an optimum filter, which heartbeat parameters are varied within predefined limits to find a maximum of the cross-correlation function; and probable peaks are located in a cross-correlation function found in this manner and the heart rate is calculated therefrom.
