Abstract

An in-vehicle ventilation system includes a power window mechanism configured to open and close a window of a vehicle and a control unit configured to control the power window mechanism. The control unit is further configured to acquire a first environmental information representing an environment inside the vehicle and a second environmental information representing an environment outside the vehicle, automatically select, based on the first environmental information and the second environmental information, a specific ventilation adjustment mode suitable for at least one occupant of the vehicle out of a plurality of ventilation adjustment modes and control the power window mechanism according to the selected ventilation adjustment mode.

Claims (22)

1. An in-vehicle ventilation system comprising:

a power window mechanism configured to open and close a window of a vehicle;

a control unit configured to control the power window mechanism; and

an occupant detection unit configured to detect a presence of an occupant on each of a plurality of seats of the vehicle,

wherein the control unit is further configured to:

determine a position of one or more seats, among the plurality of seats of the vehicle, at which an occupant is present;

acquire a first environmental information representing an environment inside the vehicle and a second environmental information representing an environment outside the vehicle;

automatically select, based on the first environmental information, the second environmental information, and the position of the one or more seats at which the occupant is present, a specific ventilation adjustment mode suitable for at least one occupant of the vehicle out of a plurality of ventilation adjustment modes; and

control the power window mechanism according to the selected ventilation adjustment mode,

wherein each of the plurality of ventilation adjustment modes correspond to a combination of windows, among a plurality of windows included in the vehicle, to be opened by the power window mechanism, and

wherein the control unit is further configured to:

determine whether the one or more seats at which the occupant is present corresponds to a driver seat position;

in a state in which the one or more seats corresponds to the driver seat position and an outside air temperature is within a certain range, windows at the driver seat position and a position in a rearward-diagonal relationship with the driver seat position are opened, and windows at remaining seat positions are closed; and

in a state in which the one or more seats corresponds to the driver seat position and the outside air temperature is not within the certain range, windows at a front passenger seat position and a seat position in a rearward-diagonal relationship with the front passenger seat position are opened, and windows at remaining seat positions are closed.

2. The in-vehicle ventilation system according to claim 1 ,

wherein the control unit has the plurality of ventilation adjustment modes in which opening degrees of one or more windows out of the plurality of windows of the vehicle are different from each other.

3. The in-vehicle ventilation system according to claim 1 ,

wherein the control unit is configured to grasp a number of occupants based on a detected state obtained by the occupant detection unit, and to reflect the number of occupants to the selection of the ventilation adjustment mode.

4. The in-vehicle ventilation system according to claim 1 ,

wherein the control unit is configured to acquire at least an information on a traveling speed of the vehicle as the first environmental information, and to acquire, as the second environmental information, a wind speed information of outside air and an outside air temperature information at a current location at which the vehicle is located.

5. The in-vehicle ventilation system according to claim 1 , wherein each of the plurality of ventilation adjustment modes correspond to the combination of windows to be opened by the power window mechanism, and an opening degree for each window among the combination of windows to be opened.

6. The in-vehicle ventilation system according to claim 1 , wherein the certain range is from 20° C.-28° C.
