Abstract: A driver is awakened by measuring a drowsiness level of the driver; detecting a behavior of the driver indicating that the drive is aware of drowsiness; setting an intensity of an awakening stimulus based on the drowsiness level and a detection result of the behavior; and generating the awakening stimulus according to the intensity. The intensity is set to be higher when the behavior of the driver is detected under a same drowsiness level than when the behavior of the driver is not detected.
