Communication control device and communication control method

A communication control device that selects a communication frequency band between a vehicle and an external base station when starting communication between the vehicle and the external base station, the communication control device configured to perform:

• measuring or determining an amount of electromagnetic noise in each frequency band inside a cockpit module, wherein the measuring or determining the amount of electromagnetic noise in each frequency band includes measuring or determining the amount of electromagnetic noise in the communication frequency band;
• identifying an electrical device that is a source of the electromagnetic noise based on frequency bands in which the amount of electromagnetic noise is greater than or equal to a predetermined value;
• setting an operating clock frequency of the electrical device to a first frequency band that differs from the communication frequency band;
• and
• upon detecting the electrical device having been identified as the source of electromagnetic noise is performing a control pertaining to vehicle travel, the operating clock frequency not being changed until the control executed by the electrical device has been completed.
