  • Patent number: 8630589
    Abstract: Individual radio sets 12a-12e constituting an onboard radio communication system operate together with an adjacent vehicle detection unit (ultrasonic sensors 13a-13e) for detecting a second vehicle adjacent to a first vehicle 11. When it detects the adjacent vehicle, a radio interference decision unit constituting the radio sets 12a-12e decides radio interference due to an onboard radio communication system with the same radio scheme. When it detects the radio interference, a frequency channel switching unit constituting the radio sets 12a-12e switches the frequency channel to be used to avoid the interference of the radio waves.
