眠り運転警報装置。 an eye blink detection unit that detects a driver's blink and outputs a blink signal in response to the blink operation;
The signal from the blink detection unit is classified into the number of blinks, the required blink time, and the blink interval time, and each of these is weighted and corrected according to the arousal level, and the total value of each of these correction values is set in advance. A drowsy driving warning device comprising: a control unit that compares and calculates the total value with a warning level and issues a warning signal when the total value exceeds the warning level.
