6. A method of monitoring a driver with epilepsy using a brain wave signal, the method comprising:
collecting, by a sensor, a brain wave signal for a driver with epilepsy in a vehicle for a predetermined time;
determining, by an analyzer, the driver's state by analyzing the brain wave signal collected for the predetermined time; and
controlling, by a controller, an operation of the vehicle on the basis of the determined driver's state,
wherein the driver's state is determined as one of a plurality of abnormal states based on a ratio of an amplitude or power spectrum value of the brain wave signal collected from the driver to a corresponding amplitude or power spectrum value of a predefined brain wave signal of the driver, wherein the predefined brain wave signal of the driver is measured when the driver is in a normal state or a seizure state,
wherein the controller differently controls the operation of the vehicle based on each of the plurality of abnormal states, and
wherein each of the plurality of abnormal states is classified based on a corresponding ratio preset in the analyzer.
