<p>PURPOSE:To prevent a driver from driving a car asleep. CONSTITUTION:When a driving condition detector 1 detects the awakening degree, a control device 2 instructs a current value depending on the detected awakening degree to a low frequency generator 3, so that a feeble low frequency current is applied to a driver through plural electrodes 4, 5 to give pulsative stimulation to the driver. In the case where the drive continues to doze at the wheel after the application of a current, the control device 2 instructs such a higher current value as to exert no bad influence upon a human body to the low frequency generator 3 so that strong pulsative stimulation is given to the driver to awaken the driver.</p> |
