Individual radio sets-constituting an onboard radio communication system operate together with an adjacent vehicle detection unit (ultrasonic sensors-) for detecting a second vehicle adjacent to a first vehicle. When it detects the adjacent vehicle, a radio interference decision unit constituting the radio sets-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-switches the frequency channel to be used to avoid the interference of the radio waves.
