Disclosed are a rear-side alert system and a method of controlling the same. The rear-side alert system may output an alert when there is a possibility of collision with an object detected in back of a host vehicle and determine a time point of the alert based on whether the object reaches a virtual alert deactivation line, so as to maintain the alert during a time interval in which there is the possibility of collision between the host vehicle and the object. Further, when the object does not pass through a boundary set on one side of the host vehicle, the rear-side alert system may set different alert the time points, thereby minimizing a time during which an unnecessary alert is output and improving reliability of the output of the alert by the rear-side alert system.

Arrangements of the present disclosure disclose a head-up display, a head-up display method, and a vehicle. The head-up display includes a head-up display component configured to display an image on a projection location. The display includes a master control component connected to a driving component. The master control component is configured to obtain vehicle information, analyze the vehicle information, and generate a control instruction based on an analysis result. The vehicle information includes vehicle positioning information and vehicle attitude information, or traveling road information and vehicle attitude information. The driving component, connected to the head-up display component, is configured to adjust the head-up display component based on the control instruction such that the projection location of the image displayed by the head-up display component remains at a consistent relative height with respect to the ground.

A configuration of selecting content corresponding to the driving situation of a driver and presenting the content to the driver, thereby enabling improvement of the safe driving consciousness of the driver, can be implemented. The configuration includes a situation data acquisition unit that acquires automobile driving situation data, an output content determination unit that determines output content on the basis of the situation data, and a content output unit that outputs the output content determined by the output content determination unit. The output content determination unit determines, as the output content, content including the details of a situation that matches or that is similar to the situation data. The output content determination unit determines, as the output content, content including the details of a risk or an accident in a situation that matches or that is similar to the situation data.

An agent device includes a plurality of agent functions configured to provide a service including a response in response to speech of an occupant of a vehicle, wherein a first agent function that is active among the plurality of agent functions is configured to activate another agent function upon receiving an instruction to activate the other agent function.

An agent apparatus includes: a first acquirer configured to acquire voice of a user; a recognizer configured to recognize the voice acquired by the first acquirer; and a plurality of agent functional units, each of the agent function unit being configured to provide services including causing an output unit to output a response on the basis of a recognition result of the recognizer, wherein, when a first agent functional unit included in the plurality of agent functional units is not able to cope with a request included in the voice recognized by the recognizer and another agent functional unit of the plurality of agent functional units is able to cope with the request, the first agent functional unit causes the output unit to output information for recommending the other agent functional unit to the user.

A system reduces motion sickness symptoms for occupants of a vehicle. The system has a control unit which is coupled to a sensor system and/or a navigation system, a vehicle seat system, and/or a display unit for receiving and/or outputting signals. The control unit is designed to generate seat adjustment signals and/or display signals depending on received surroundings data and/or vehicle component data.

An agent device includes a plurality of agent functional units configured to provide a service including causing an output part to output a voice response in accordance with speech of an occupant of a vehicle and a manager configured to activate one agent functional unit corresponding to a first activation phrase that has been spoken among the plurality of agent functional units when the occupant of the vehicle has spoken the first activation phrase individually set for each of the plurality of agent functional units and to activate two or more agent functional units corresponding to a second activation phrase that has been spoken when the occupant of the vehicle has spoken the second activation phrase commonly set for the two or more agent functional units among the plurality of agent functional units.

Permissible level information indicating the highest permissible level of driving assistance control for each of sections on a target route is stored in a storage device. In a first section of the target route, the highest permissible level is a first level. In a second section that follows the first section, the highest permissible level is a second level higher than the first level. In a third section that follows the second section, the highest permissible level is a third level different from the second level. In a case where the length of the second section or a passage time taken for a vehicle to pass through the second section is smaller than a threshold value, the processor performs a level maintenance process of maintaining the selection level in the second section at a level equal to the selection level in the first section.

An information providing device of an embodiment is an information providing device including an acquirer that acquires personal information of a plurality of occupants in a moving body, a processor that generates integrated personal information by combining at least a part of the personal information of the plurality of occupants acquired by the acquirer, and an information provider that provides information to the plurality of occupants based on the integrated personal information processed by the processor.

An in-vehicle apparatus mounted in a vehicle includes: an assistance processing unit that executes assistance processing for providing a user with specified information; and a display control unit that performs control to display a list according to a sequential order of the assistance processing executed by the assistance processing unit.
