1. An electrified vehicle, comprising:
a first motor that drives a first wheel;
a second motor that drives a second wheel that is different from the first wheel;
a temperature sensor provided for the first motor; and
a control device, wherein the control device
estimates a temperature of the first motor based on a detection signal from the temperature sensor,
estimates a temperature of the second motor by correcting the temperature of the first motor based on information indicating a relative relation between operation of the first motor and operation of the second motor,
controls the operation of the first motor based on the temperature of the first motor that is estimated, and
controls the operation of the second motor based on the temperature of the second motor that is estimated.
