徴とする、自動車用運転警報装置。 A steering wheel angle differentiating means for detecting differential information of a steering wheel angle in an automobile is provided, and the magnitude of the absolute value of the differential signal from the steering wheel angle differentiating means and a first reference value and a second reference value larger than the first reference value is determined. A comparison means for comparing the relationship, and a comparison result from the comparison means, while the absolute value of the differential signal is smaller than the first reference value, the danger potential value is increased by a required ratio, and the differential signal is While the absolute value of the differential signal is between the first reference value and the second reference value, the danger potential value is decreased by a predetermined value every time a certain period of time elapses, and the absolute value of the differential signal is equal to the second reference value. The present invention is characterized by being provided with a danger potential counter that increases the danger potential value by a predetermined value when the danger potential value exceeds the danger value, and an alarm means that issues an alarm when the danger potential value from the danger potential counter exceeds the danger value. , automobile driving warning device.
