Abstract
The present invention provides an in-vehicle communication device and an in-vehicle system that can establish communication, in a short time, between applications corresponding to the same communication protocol between in-vehicle processing devices connected to communication buses having different communication protocols. In the present invention, when the first communication controllerhas received a specific message from the first in-vehicle processing deviceconnected to the first communication bus, the in-vehicle communication devicetransmits a communication protocol switching command from the second communication controllerto the second in-vehicle processing deviceconnected to the second communication busto switch a communication protocol setting of the second communication controller to the same communication protocol setting as that of the first communication bus.
