Wireless data that is obtained via a radio (91) and stored in a radio-control-unit buffer (5A) is transferred to an intermediate wireless-data buffer (5M) by a wireless-data reception unit (321). Also, intra-vehicle data stored in an intra—vehicle-communication-control-unit buffer (5B) is transferred to an intermediate intra-vehicle-data buffer (5N) by an intra-vehicle-data reception unit (331). When data is being thus transferred, a wireless-data reception task is prioritized over other processes that transfer data, such as an intra-vehicle-data reception task. Since wireless data received by a radio control unit (22) is sequentially transferred to the intermediate wireless-data buffer (5M) as soon as said wireless data is stored in the radio-control-unit buffer (5A), the likelihood of the radio-control-unit buffer (5A) becoming full due to said wireless data is reduced. |
