1. An electronic control unit that is mounted on a vehicle which is configured to be charged with an external power supply and that receives a pilot signal via a charging cable before being supplied with a power when the vehicle is connected to the external power supply via the charging cable, the electronic control unit comprising:

  • a pilot voltage setting circuit that changes a voltage of the pilot signal in a stepwise manner;

    a processor that performs a process necessary for control of charging based on the pilot signal, and that controls the pilot voltage setting circuit to change the voltage of the pilot signal;

    an input buffer that is disposed in a stage preceding a pilot signal input port of the processor; and

    an input buffer voltage setting circuit that changes an input voltage of the input buffer so as to be within a recommended input voltage range of the input buffer based on the change in the voltage of the pilot signal.
