Abstract
A method of determining a vehicle situation using acoustic data and a low-frequency removal filter includes a step of acquiring, in an auditory sensor section mounted on a vehicle, acoustic data generated from the outside of the vehicle, a preprocessing step of removing, in a calculation section, low-frequency components from the acoustic data; and a step of calculating and determining, in the calculation section, an outside-of-vehicle situation event by using the preprocessed acoustic data.
Claims15
A method of determining a state of a vehicle using acoustic data and a low-frequency removal filter, the method comprising:
- acquiring, by an auditory sensor disposed at the vehicle, acoustic data generated from an outside of the vehicle;
- removing, by a calculation section, a low-frequency component from the acoustic data, the calculation section being implemented using one or more computing devices;
- and
- determining, by the calculation section, an external vehicle situation event based on the acoustic data from which the low-frequency component is removed.
