Abstract: A fraudulent control prevention system for a time-triggered-communication-type onboard network. The fraudulent control prevention system has a first error monitoring device that has a first frame transmission/reception part and a first error detection part. The first frame transmission/reception part receives frames that flow over the onboard network. When the first error detection part detects that an error has occurred for a frame received by the first frame transmission/reception part, the first error detection part induces transmission of an error notification frame that is for giving notification that an error has occurred for the frame. The fraudulent control prevention system also has second error monitoring devices that each have a second frame transmission/reception part and a second error detection part. The second frame transmission/reception part receives the error notification frame. When the second error detection part has not, relative to the branch thereof, detected an error in relation to the frame for which an error occurred that is included in the received error notification frame, the second error detection part transitions at least one of the second error monitoring devices to an invalidation mode that treats the frame as a frame to be invalidated and invalidates subsequent reception of relevant frames.
