  • Patent number: 10618522
    Abstract: An in-vehicle monitoring and intervention system for detecting whether a driver in a vehicle is drowsy by monitoring a plurality of physiological signals of the driver is provided. The in-vehicle monitoring and intervention system includes at least a processor and an apparatus, the apparatus can be integrated into a seat belt or attached thereto as a discrete hardware apparatus, which includes at least an ECG sensor, a respiratory sensor, an acceleration sensor, a filtering system, and an intervention module. The filtering system further comprises one or more filters for suppressing noise and reducing motion artifacts. The processor is configured to compare the detected physiological signals with the signals stored in a learning module of the in-vehicle monitoring and intervention system for determining the drowsiness state. If the driver is determined to be drowsy, a warning signal is outputted to alert the driver.
