10. A vehicle communication method in which communication between a plurality of communication devices is performed, wherein the plurality of communication devices include a first communication device and a second communication device, comprising:
-
determining beforehand the total sum of the amounts of communication data per unit time sent from all the communication devices that does not exceed a predetermined value of communication data, and executing a process by each of the communication devices at predetermined time intervals, in which if an amount of communication data per unit time sent from the first communication device is increased, an amount of communication data per unit time sent from the second communication device is decreased so that a total sum of the amounts of communication data per unit time sent from all the communication devices does not exceed a predetermined value. - View Dependent Claims (11, 12)

13. A vehicle communication system in which communication between a plurality of communication devices is performed, comprising:
-
a first communication device and second communication devices, and a higher level device, wherein the total sum of the amounts of communication data per unit time sent from all the communication devices does not exceed a predetermined value of communication data, the first communication device comprises a data output pattern switching device that changes the amount of communication data sent, by switching a data output pattern of the first communication device to a data output pattern ordered by the higher-level device, and the amount of communication data sent from the respective communication device is determined beforehand in accordance with a data output pattern at predetermined time intervals so that a total sum of the amounts of communication data sent from all the communication devices of the vehicle communication system does not exceed the predetermined value of communication data. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
