Abstract: A seat reclining position control device includes: a seat on which an occupant of a vehicle sits; an adjustment part configured to adjust an angle of a backrest of the seat; a sleep state detection unit configured to detect a sleep state of the occupant; a control unit that operates the adjustment unit to control the angle; and a vehicle interior detection unit configured to detect a vehicle interior state of the vehicle. The control unit implements a seat angle control to adjust the angle of the backrest for the occupant in the sleep state based on the vehicle interior state to a suitable sleeping angle suitable for sleeping when the sleep state detection unit detects the sleep state of the occupant.

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.

Abstract: A travel control apparatus is provided. The travel control apparatus acquires driver abnormality information indicative of an abnormality of a driver of a vehicle, makes a determination that the driver is in a driving difficulty state based at least on the driver abnormality information, and activates a lane departure prevention function and a cruise control function of the vehicle at substantially the same time during a time period between when the driver abnormality information is acquired and when the driving difficulty state is determined. Together with activating the lane departure prevention function and the cruise control function, the travel control apparatus outputs notification request information to a human machine interface controller controlling a notification device which issues a notification to a passenger of the vehicle. The notification request information causes the notification indicative of activation of the lane departure prevention function and the cruise control function to be issued.
