Abstract

PURPOSE: To prevent false alarming by delivering an alarm when the number of steering operation exceeding the angle width set beforehand reaches a prescribed value in addition to the delivery thereof at various operations required for driving in a device for warning a driver of the lowering of his wakefulness.
CONSTITUTION: A steering-angle detecting circuit 2 to which an input is made from a steering-angle sensor 1 delivers a steering-angle pulse every time when a change exceeding the angle width set beforehand occurs. On the other hand, when a direction indicator switch 3 is turned on, for instance, an OR circuit 7 delivers a signal in the course that the switch is on and for a certain time after completion of an on state. Since there is no fear of lowering of the wakefulness of a driver while the direction indicator or the like operates, a signal of the OR circuiti7, etc. indicating the aforesaid states is inverted by a NOT circuit 29, whereby the steering-angle pulse is prevented from passing through an AND circuit 30. When no prevention is conducted, the steering-angle pulse which passes through the AND circuit 30 is inputted in a steering frequency detecting circuit 31 and a sharp steering detecting circuit 32 and gives an alarming signal to an alarming part 35 when a count value within a time set beforehand reaches a value set beforehand, whereby an alarm is delivered.
