車両用通信装置。[Scope of claim for utility model registration] A communication device in a vehicle control system that performs multiplex communication and exchanges data between multiple controllers that control equipment in a vehicle, where a specific controller is a master controller and other controllers is a slave controller, the master controller is provided with a status signal generating means for transmitting a status signal to each slave controller indicating whether the status of each slave controller is normal or not, and each slave controller is provided with a status signal generating means for transmitting a status signal to each slave controller. A return means is provided for returning the same status signal to the master controller when receiving the status signal from the generation means, and the master controller is provided with a return means for returning the same status signal to the master controller, and the master controller is provided with a return means for returning the same status signal to the master controller. and a comparison means for comparing the status signals, and when the comparison means determines that the returned status signal matches the status signal sent by the master controller, the data part of the status signal that corresponds to the slave controller is normalized. The state indicates that
A data setting means is provided to indicate an abnormality when they do not match, and the master controller and each slave controller have a determining means for determining whether or not to adopt the data transmitted by the controller based on the content of the status signal. A vehicle communication device characterized in that:
