1. An electronic control unit mounted in a vehicle, comprising:
a first processing unit that is configured to execute predetermined arithmetic processing and generate a first control signal for controlling the vehicle;
a second processing unit that is redundantly disposed with the first processing unit and is configured to generate a second control signal for controlling the vehicle;
a first power supply circuit that is configured to generate power for operating the first processing unit based on power supplied from a first power supply device mounted in the vehicle;
a second power supply circuit that is configured to generate power for operating the second processing unit based on power supplied from a second power supply device mounted in the vehicle; and
a communication line that communicably connects the first processing unit and the second processing unit to each other, wherein
the communication line includes (i) a pair of physical layer devices that are configured to convert an electrical signal and (ii) a capacitor that is disposed between the pair of physical layer devices on the communication line and is configured to electrically isolate the first processing unit and the second processing unit from each other by AC coupling, and
the pair of physical layer devices are configured to convert the electrical signal to perform communication using the AC coupling.
