When ignition is on, a shift position is a neutral position, and shut-down of the inverter is cancelled in a state that a short circuit fault occurs in any phase among multiple phases of the inverter, the electrically driven vehicle performs a first ON control to turn on upper and lower arms in any arbitrary phase among the multiple phases. When an abnormality is detected in the inverter due to the first ON control, the electrically driven vehicle performs a second ON control to turn on upper and lower arms in a different phase from the phase of the first ON control.
