First Claim
1. An onboard apparatus which estimates a position and traveling direction of a vehicle from a vehicle state and map information, and determines a vehicle to exchange intervehicle communication, and which carries out communication with a cloud server that creates and transmits communication establishment information necessary for establishing intervehicle communication between vehicles so as to exchange the intervehicle communication, the onboard apparatus comprising:
- a vehicle information acquirer to obtain vehicle information about the vehicle state of its own vehicle;
a cloud communicator to transmit the vehicle information obtained by the vehicle information acquirer to the cloud server, and to receive the communication establishment information transmitted from the cloud server;
an intervehicle communicator to carry out intervehicle communication; and
a controller to instruct the intervehicle communicator to perform the intervehicle communication and to establish communication in accordance with the communication establishment information the cloud communicator receives,wherein the cloud communicator receives, from the cloud server, estimate information indicating that an area that enables intervehicle communication of the intervehicle communicator and an area that enables the intervehicle communication of an onboard apparatus of another vehicle are getting closer to each other, in order to enable the intervehicle communication to become possible.
