An apparatus configured to switch a driving mode of a vehicle comprising: a sensing unit configured to sense a state of a driver of a vehicle that is configured to be driven automatically or manually; an intention detecting unit configured to detect whether or not the driver intends to switch a driving mode of the vehicle from an automatic driving mode to a manual driving mode based on the state of the driver sensed by the sensing unit when the vehicle is being driven in the automatic driving mode; an operation detecting unit configured to detect whether the driver is able to operate the vehicle in the manual driving mode using the state of the driver sensed by the sensing unit based on the intention detecting unit detecting that the driver intends to switch a driving mode of the vehicle from the automatic driving mode to the manual driving mode; a driving state predicting unit configured to predict a driving state of the vehicle according to manual driver operation in the manual driving mode for a preset period of time based on the operation detecting unit detecting that the driver is able to operate the vehicle in the manual driving mode; and a control unit configured to determine whether the predicted driving state of the vehicle meets a preset condition and switch the driving mode of the vehicle from the automatic driving mode to the manual driving mode based on a determination that the predicted driving state of the vehicle meets the preset condition, characterized in that the operation detecting unit is further configured to: calculate a degree of fatigue of the driver based on a degree of the driver's blinking and a degree to which the driver's eyelids cover the eyes; determine whether the calculated degree of fatigue of the driver meets a threshold degree; and detect that the driver is able to operate the vehicle in the manual driving mode based on a determination that the calculated degree of fatigue of the driver meets the threshold degree, wherein the driving state predicting unit is configured to predict the driving state of the vehicle according to a driver's operation that is input on the assumption that the driving mode of the vehicle is the manual driving mode for the preset period of time in a state where the driving mode of the vehicle is the automatic driving mode. a sensing unit configured to sense a state of a driver of a vehicle that is configured to be driven automatically or manually;
