Abstract: Provided is an in-vehicle information processing system that can be operated intuitively. An in-vehicle information processing system (10) includes a display (11), a touch operation interface (12), an imaging unit (13), and a controller (14). The display (11) includes at least one screen. The touch operation interface (12) detects contact by an operation hand of an operator. The imaging unit (13) captures an image of the touch operation interface (12) and at least a portion of the operation hand. The controller (14) associates position coordinates in an operation region (R2) on the screen with position coordinates in a predetermined region (R1) of the touch operation interface (12) and causes at least a portion of the operation hand to be displayed in overlap on the screen on the basis of the image captured by the imaging unit (13).

Abstract: A sleepiness level prediction device (1) according to one embodiment of the present invention is provided with: a vehicle information acquisition unit (10) that acquires information regarding a vehicle; a driver information acquisition unit (20) that acquires information regarding a driver; and a control unit (40) that calculates, on the basis of the acquired information regarding the vehicle, a stimulus quantity (S) provided to the driver on the basis of the driver's present driving load and the driving load after a predetermined time period, that calculates a non-acclimation degree (H) indicating a degree to which the driver is not acclimated to driving, on the basis of a change (?S) of the calculated stimulus quantity (S), and that predicts a sleepiness level (D1) of the driver after a predetermined time period on the basis of the calculated non-acclimation degree (H) and the driver's present sleepiness level (D0) estimated on the basis of the acquired information regarding the driver.

Abstract: A vehicle travel controller carries out automatic travel control of controlling a vehicle to travel automatically based upon travel state information of the vehicle and information on an exterior of the vehicle. An automatic/manual traveling changeover switch is capable of switching between an automatic driving mode in which the automatic travel control is carried out by the vehicle travel controller and a manual driving mode in which the driver drives the vehicle manually. A driving posture controller controls a reclining motor so that the reclining angle of the driver's seat in the automatic driving mode is larger than the reclining angle of the driver's seat in the manual driving mode.
