Abstract: Disclosed is a vehicular electronic device including a processor which, in the situation in which an autonomous vehicle generates a horn signal during autonomous driving, determines a horn-signal-transmitting entity and a horn-signal-receiving entity, selects at least one of a horn signal in an audible frequency band or a horn signal in an inaudible frequency band, and outputs the selected horn signal to the horn-signal-receiving entity.
