Original Abstract Submitted

In a control method of a motor drive system, when a first motor corresponding to a first drive wheel is being driven in a second drive mode among a first drive mode in which the first motor is driven by a first inverter of the motor drive system and connected to a first end of each of coils of the first motor and the second drive mode in which the first motor is driven by the first inverter and a second inverter connected to a second end of each of the coils and configured to selectively operate, whether or not the second inverter malfunctions is determined. When the second inverter malfunctions, a drive mode is changed so that the first motor is driven in the first drive mode. An output limit of the first motor in the first drive mode is relaxed.
