IN-VEHICLE COMMUNICATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an in-vehicle communication apparatus capable of suppressing a data transfer loss caused by occurrence of radio interference by predicting a frequency band where the radio interference occurs, and avoiding the frequency band so as not to use it. SOLUTION: The in-vehicle communication apparatus comprises: a vehicle-inside communication means for performing radio communication with a mobile terminal 2 while changing a frequency to be used in a time division manner; a communication frequency optimizing means for optimizing a frequency to be used for radio communication performed by the vehicle-inside communication means; a vehicle-outside communication means for performing radio communication with a base station device 3 outside a vehicle using the same frequency band as the vehicle-inside communication means; and a communication prediction means for predicting occurrence of communication due to the vehicle-outside communication means. If the occurrence of radio communication is predicted by the communication prediction means, the communication frequency optimizing means optimizes the frequency to be used for the radio communication performed by the vehicle-inside communication means so as not to include a specific frequency to be used for the vehicle-outside communication means, thereby simultaneously performing vehicle-inside communication and vehicle-outside communication.
