There are provided a monitor for monitoring a human condition of a driver, and an awakening device for awakening a driver, which starts operation when received a predictive signal for fall-asleep being a signal for energy metabolism transition from an active state into a sleep state. The awakening device is structured to stimulate a pressure sense of the driver by reclining a seat back of a driver seat forward or rearward to thereby cause a shift force. Accordingly, without regard to an alarm reaction level to an alarm sound, it is possible to stimulate the driver and whereby awaken the driver more surely.
