8. A vehicle classification method performed by a control unit, the vehicle classification method comprising:
-
acquiring a vehicle detection signal from a second sensor; acquiring a sound transmitted from a first sensor; storing the acquired sound in association with the vehicle detection signal; determining whether the vehicle detection signal is acquired from the second sensor within a predetermined time; and classifying a model of each vehicle on the basis of a result of analyzing a sound stored for each vehicle detection signal when a result of the determination is that the vehicle detection signal is not acquired. - View Dependent Claims (9, 10, 11, 12, 13, 14)
