Abstract

PURPOSE: To alarm against a doze at the wheel by detecting vehicle speed reduction in monotonous running for detecting reduction of degree of awakening without asking a response from a driver.
CONSTITUTION: A monotonous running detecting circuit 100 is provided with a shift position detecting switch 1 for detecting that gear position is on the top, a brake operation detecting switch 2 for detecting that the brake operation is carried out and a timer 7 to detect that the shift position is on the top and the brake operation is not carried out for a predetermined time. Also, a vehicle speed change detecting circuit 200 detects the increase or decrease of the vehicle speed over a predetermined amount by means of a vehicle speed change detecting section 3 and counter circuit 8a. Further, a decision circuit 300 decides on the basis of signals of both circuits through a time setting circuit 9 that the vehicle speed has changed over a predetermined amount within a set time in the monotonous running, and activate an alarm circuit 400. Thus, by the use of the circuit 200, any response from a driver is not needed and trouble associated therewith can be eliminated.
