Abstract
A method for adjusting a driving control authority of a vehicle includes: generating stimulation for a driver using a stimulation generator; measuring a driver reaction signal in response to the generated stimulation using a measurement device; processing the measured driver reaction signal using a signal processor; determining a driver state based on the processed driver reaction signal using a determiner; and adjusting the driving control authority of the vehicle according to the determined driver state using a vehicle controller.
Claims13
A method for adjusting a driving control authority of a vehicle, the method comprising:
- generating stimulation including sound generated when a driver boards the vehicle for a driver using a stimulation generator, wherein the sound includes a welcome sound or a seat belt warning sound;
- measuring a driver reaction signal in response to the generated stimulation using a measurement device, wherein the driver reaction signal comprises measuring a brainwave of the driver;
- processing the measured driver reaction signal using a signal processor;
- determining a driver state based on the processed driver reaction signal using a processor;
- and
- adjusting the driving control authority of the vehicle according to the determined driver state using a vehicle controller,
- wherein the processing of the driver reaction signal comprises:
- performing filtering on the driver reaction signal to classify a signal other than the brainwave as noise;
- extracting an event-related potential (ERP) from the filtered driver reaction signal;
- and
- extracting, from the ERP, a potential having a maximum amplitude value after a specific time elapses from a time at which the stimulation is generated.
A system for adjusting a driving control authority of a vehicle, the system comprising:
- a stimulation generator to generate stimulation for a driver, wherein the stimulation including sound generated when a driver boards the vehicle, wherein the sound includes a welcome sound or a seat belt warning sound;
- a measurement device including a sensor device configured to measure a driver reaction signal in response to the generated stimulation;
- a signal processor configured to:
- process the measured driver reaction signal, wherein the driver reaction signal comprises measuring a brainwave of the driver;
- perform filtering on the driver reaction signal to classify a signal other than the brainwave as noise;
- extract an event-related potential (ERP) from the filtered driver reaction signal;
- and
- extract, from the ERP, a potential having a maximum amplitude value after a specific time elapses from a time at which the stimulation is generated;
- a processor configured to determine a driver state based on the processed driver reaction signal;
- and
- a vehicle controller configured to adjust the driving control authority of the vehicle according to the determined driver state.
