<p>A travel mode determination device is described comprising: an inertial sensor (or a plurality of inertial sensors); a first filter configured to filter a first frequency band of the inertial sensor (for example in an electrical car (for example in motion), or on a bicycle (for example in motion); a second filter configured to filter a second frequency band of the inertial sensor; a comparator configured to compare a power spectral density of the first filter with a power spectral density of the second filter; and a travel mode determination circuit configured to determine a travel mode of the travel mode determination device based on the comparator.</p> |
