Title: ELECTRONIC CONTROL UNIT, COMMUNICATION METHOD, AND IN-VEHICLE NETWORK SYSTEM
Abstract:
An X-ECU (100) is provided with: a reception unit (110a) which sequentially receives frames from a CAN bus and stores the frames in a reception buffer (120a); a reception unit (110b) which sequentially receives frames from a second network and stores the frames in a reception buffer (120b); a generation unit (130) which refers to the data in each of the reception buffers and sequentially generates a first kind of data which is data for the traveling control of a vehicle and a second kind of data which is data used in areas other than the traveling control of the vehicle, and stores each kind of data in respective transmission buffers (140a, 140b); and a transmission unit (150) which preferentially transmits prioritized data which is one of the kinds of data in the transmission buffers.
