An inverter control method for controlling a switching of an inverter in a vehicle, the vehicle having: a motor for transmitting torque to drive wheels; the inverter for converting DC power into AC power mutually and supplying the AC power to the motor; and a DC power source for supplying the DC power to the inverter, the control method including: determining whether or not a power supply to the inverter is stopped; executing a short-circuit switching control to turn on switching elements provided in the inverter when the power supply to the inverter is stopped; obtaining a motor state parameter as a variable representing a state of the motor, the motor state parameter being used as a determination standard for determining whether or not an oscillation occurs in the vehicle; and stopping the short-circuit switching control before the oscillation occurs in the vehicle based on the motor state parameter obtained, when the power supply to the inverter is stopped.
