PROBLEM TO BE SOLVED: To allow communication modules connected to CAN(Control Area Network) buses having different communication speeds to communicate with each other without increasing a communication load.SOLUTION: A communication unit is characterized to control CAN communication between modules connected to a plurality of CAN buses having different communication speeds by a CPU disposed in a microcomputer by connecting a plurality of different CAN controllers connected to the CAN buses having different communication speeds to a plurality of serial ports disposed in the microcontroller, and processing CAN messages input from the CAN buses via the CAN controllers and the serial ports on the basis of input serial port IDs and CAN message IDs. |
