Abstract
PURPOSE: To increase the driver-awakening effect of a detector for the dozing of a driver at the wheel, by providing the detector with an alarm circuit adapted to receive as an input thereinto an output from a circuit for use in detecting the degree of waking of a driver, and to give an alarm in accordance with the degree of waking of a driver.
CONSTITUTION: When a decrease in the degree of waking of a driver has been ascertained in a circuit 10 for detecting the dozing of a driver at the wheel to output an alarm signal therefrom, a one-shot multivibrator 11a is turned on for a predetermined period of time by the first pulse of the alarm signal. Consequently, a light emitting diode 15 is connected to a power source 13 through an electronic switch 12a. When the second pulse is output from the circuit 10, a one-shot multivibrator 11b is turned on to allow a speaker 18 to give an alarm. When the third pulse is output, a one-shot multivibrator 11c is turned on, and an electronic relay 12c is A-C connected to turn on a driving transistor 20. As a result, a fan motor 22 is intermittently driven. When such three kinds of alarm means are operated in order in accordance with the cumulative degree of alarm signals, the driver-awakening effect of detector for the dozing of a driver at the wheel can be increased to a great extent.
