Abstract:
1. An anti-drowsing device comprising: a warning output device that outputs a warning when a collision possibility is detected between a preceding object and the vehicle; a warning timing change device that establishes an early-warning mode in which the timing of output of a warning by the warning output device is advanced from that used in a normal mode; and an eye-closing period measurement device that monitors the state of the driver's eyes and measures the period during which the driver's eyes are closed, wherein the warning timing change device establishes the early-warning mode when the eye-closing period measured by the eye-closing period measurement device becomes equal to or greater than a first threshold value, and thereafter maintains the early-warning mode until the eye-closing period falls below a second threshold value which is smaller than the first threshold value.
