A vehicle includes: a capturer to capture a driver of the vehicle driving in an autonomous driving mode to obtain driver position information; a driver state detector to detect a state of the driver; and a controller to determine a time required to change from the autonomous driving mode to a manual operation mode based on the obtained driver position information and the detected driver state. In particular, the controller controls the change to driving mode of the vehicle based on the determined time to change from the autonomous driving mode to the manual operation mode.

A drowsiness sign notification system applied to a vehicle includes a driver monitor and a controller. The driver monitor detects a driver state being a state of a driver of the vehicle. The controller executes a drowsiness sign determination process that determines whether or not the driver shows a drowsiness sign based on the driver state. When it is determined that the driver shows the drowsiness sign and an activation condition is satisfied, the controller executes rest area informing process that informs the driver of a rest area. The activation condition of the rest area informing process is set from a viewpoint of a relationship between a location of the rest area and a target route of the vehicle, or an expected time required for the vehicle to reach the rest area.

A method for automatically controlling an in-cabin environment for a passenger in an autonomous vehicle includes monitoring a state of the passenger via a video sensor; determining whether the state of the passenger corresponds to one of preset states of a predetermined number; and adjusting, when the state corresponds to the one of the preset states, any one or any combination of any two or more of a seat, an air conditioning system, a lighting system, a sound system, a variable window tinting, and a variable sunroof of the autonomous vehicle based on the state. The determining of the state of the passenger includes detecting a plurality of determination target objects from a video of the video sensor, cropping an image of each of the plurality of determination target objects, and determining whether the state of the passenger corresponds to the one of the preset states.

A vehicle system including a vehicle component and a controller is provided. The controller may selectively activate the vehicle component and communicate with a mobile unit including an interface. The controller may be programmed to interact with the mobile unit upon detection by accessing vehicle sleep mode instructions preprogrammed by a user via the interface in which the controller activates the vehicle component according to an escalation sequence schedule to disengage a vehicle sleep mode. The system may further include a sensor in communication with the vehicle component and the controller. The controller may be further programed to activate the vehicle component according to the escalation sequence schedule based on receipt of a signal from a sensor indicating a passenger is asleep.

An autonomous driving assistance device includes: a determination unit for determining whether or not a driver of a vehicle needs a rest on the basis of detection information of a state of the driver; and a control unit for causing an output device of the vehicle to output a pattern that prompts the driver to sleep through at least one of sight, hearing, or touch during a period in which the vehicle has started moving to a parking area and is parked at the parking area in a case where the determination unit has determined that the driver needs a rest.

With an illuminance adjusting apparatus, if automatic driving of a vehicle is being performed, a control unit determines whether or not an estimated time that it is estimated to take until the automatic driving ends is less than or equal to a reference time. If it is determined by the control unit that the estimated time is less than or equal to the reference time, a drive unit reduces illuminance of an interior light for illuminating an interior of the vehicle.

An information processing device includes a control unit configured to: acquire information on a destination of a user who uses a resting unit including equipment on which the user is able to sleep, information on an arrival time at the destination, and information on a place in which the user uses the resting unit; transmit a command to a traveling unit configured to be coupled to the resting unit and carry the resting unit such that the traveling unit is coupled to the resting unit and arrives at the destination at the arrival time; and transmit a command to a stimulation device configured to stimulate the user who is using the resting unit such that the stimulation device is activated before the traveling unit is coupled to the resting unit or before the traveling unit departs for the destination after being coupled to the resting unit.
