RELAY APPARATUS

摘要

A relay apparatus provided to a vehicle, performing first data communication with a first communication apparatus arranged outside the vehicle, and performing at least second data communication with multiple second communication apparatuses provided to the vehicle is provided. The relay apparatus includes a permission determination portion and an initiation switch portion. The permission determination portion determines whether first data communication between the first communication apparatus and a target second communication apparatus is permitted. The permission determination portion receives the first communication frame from the first communication apparatus through a connection switch portion determining a connection destination according to a control signal. The initiation switch portion outputs to the connection switch portion, the control signal designating the target second communication apparatus as the connection destination of the first communication apparatus.
