Abstract:
1. A communication device comprising: a transmission/reception unit that receives transfer data for indicating vehicle running conditions, and performs a process of transmitting the transfer data after passage of a standby time following receipt of the transfer data; and a data processing unit that performs a process of calculating the standby time on the basis of the position of a host vehicle and the received transfer data, wherein the transfer data for indicating the vehicle running conditions comprise data to be transferred, position information of a destination of the data to be transferred, position information of relay points used to determine a route to the destination, and position information of a last transferring vehicle, and wherein, in the case where the host vehicle is not located in a predetermined range on the basis of the relay points, the data processing unit sets a first time as the standby time that becomes shorter as a distance between the position of the last transferring vehicle and the position of the host vehicle becomes longer, and in the case where the host vehicle is located in the predetermined range, the data processing unit sets a second time as the standby time that becomes longer as a distance between the position of the host vehicle and the position of a relay point becomes longer.
