Referring to FIG. 1 , an apparatus for cleaning indoor air in a vehicle according to an embodiment of the present invention includes a probe vehicle 10 , a service server 30 , and a subject vehicle 40 .

The probe vehicle 10 detects an air pollution level and a current location of outdoor air in a currently traveling area, and transmits the detected air pollution level and current location to the service server 30 through a communication network.

Here, as the communication network, a wireless communication method may be employed, and a wireless LAN (WLAN) or Wi-Fi may be employed as the wireless communication method.

A plurality of probe vehicles 10 are provided, each of which can measure the air pollution degree of outdoor air while driving in various regions.

The service server 30 receives the air pollution level and the current location from each of the probe vehicles 10 , and sets the air pollution area using these air pollution levels and the current location.

Since the current location transmitted from the probe vehicle 10 corresponds to the location in which the probe vehicle 10 is currently driving, the service server 30 operates such as a radius of 5 km based on the current location transmitted from the probe vehicle 10 . A large area can be set as an air pollution area.

When the air pollution area is set, the service server 30 generates air pollution area setting information including the air pollution area and the air pollution degree, and transmits the generated air pollution area setting information to the own vehicle 40, respectively. .

When receiving the air pollution area setting information from the service server 30 , the own vehicle 40 purifies the indoor air of the own vehicle 40 according to the air pollution area setting information and the driving information of the own vehicle 40 .

The driving information may include current speed, current location, and road information of the vehicle 40 .

That is, the subject vehicle 40 determines whether or not the subject vehicle 40 will pass through an air pollution area based on the current speed, current location, road information, and the like of the subject vehicle 40 . As a result of the determination, if it is determined that the subject vehicle 40 will pass through the air polluted area, the subject vehicle 40 uses the air conditioner 42 before entering the air polluted area so that the outdoor air is transferred to the indoor air of the subject vehicle 40 . to purify the indoor air of the subject vehicle 40 in the state that it does not flow into the

Referring to FIG. 2 , the probe vehicle 10 includes a probe vehicle outdoor air sensor 11 , a probe vehicle GPS module 12 , and a probe vehicle controller 13 .

Through this, the current position of the probe vehicle 10 is detected.

Here, the first setting range is an air pollution degree range of outdoor air, which is a standard for determining that the outdoor air is polluted, and the set time is a time for clearly confirming whether the corresponding area corresponds to an air polluted area.

For example, when the probe vehicle 10 passes through a point where dust is temporarily generated, the corresponding point cannot be determined as an air pollution area. Accordingly, the probe vehicle control unit 13 detects the current location only when the air pollution level is within the first set range for a set time, for example, 5 seconds or more. Through this, the accuracy of whether the current location in which the probe vehicle 10 travels is an air polluted area may be improved.

The damper unit 422 operates in either an outdoor air mode for introducing outdoor air into the interior of the vehicle 40 or a betting mode for blocking outdoor air from entering the vehicle 40 .

The subject vehicle outdoor air sensor 43 detects an air pollution degree of outdoor air of the subject vehicle 40 .

The subject vehicle indoor air sensor 44 detects an air pollution degree of the indoor air of the subject vehicle 40 .

In this case, each of the vehicle outdoor air sensor 43 and the vehicle indoor air sensor 44 detects carbon dioxide (CO ₂ ), mesh dust, yellow dust, etc. contained in the outdoor air or outdoor air of the vehicle 40 , respectively. In addition, components included in outdoor air, such as nitrogen (N₂), oxygen (O₂), argon (A), neon (Ne), krypton (Kr), and xenon (X), can be detected. can

The subject vehicle controller 45 controls the air conditioner 42 according to the air pollution area setting information received from the service server 30 and the driving information of the subject vehicle 40 detected by the driving information detection unit 41 to The outdoor air flowing into the interior of the vehicle 40 is blocked, and the indoor air of the vehicle 40 is purified through the air purifier 60 .

Here, the driving information may include the current speed, current location, and road information of the subject vehicle 40 .

The vehicle controller 45 may receive the current speed, current location, and road information of the vehicle 40 from the GPS module 411 or the portable terminal 412 of the vehicle.

In more detail, the subject vehicle controller 45 determines whether the subject vehicle 40 enters the air pollution area based on the path of the subject vehicle 40 , and at this time, the subject vehicle 40 enters the air pollution area. If it is determined that the vehicle will enter the , an expected entry time for which the vehicle 40 is expected to enter the air pollution area is calculated using the driving information of the vehicle 40 .

In this case, the vehicle controller 45 calculates an expected entry time expected to enter the air pollution area using the current speed, current location, road information, and air pollution area of the vehicle. That is, the vehicle control unit 45 detects the distance from the current location to the air pollution area from the road information on the route, and calculates the expected entry time when the vehicle 40 drives the corresponding distance at the current speed. have.

The driving route of the subject vehicle 40 may be obtained from a navigation terminal of the subject vehicle 40 or a portable terminal 412 on which a navigation application is mounted. Since a person skilled in the art can easily invent a point where the own vehicle GPS module 411 or the portable terminal 412 sets a route to the destination and guides the route to the destination according to the set route, a detailed description thereof will be omitted.

In addition, the subject vehicle control unit 45 determines that there is no junction in the path from the current location of the subject vehicle 40 to the air pollution area even if a route from the navigation terminal or the portable terminal 412 to the destination is not set. It can be judged that there is an air-contaminated area on the path of (40). Accordingly, as described above, the vehicle controller 45 may detect an expected entry time expected to enter the air pollution area using the current speed, current location, and road information of the vehicle air pollution area as described above.

After detecting the expected entry time as described above, the subject vehicle control unit 45 stores the current operating state of the air conditioner 42 . Next, the subject vehicle controller 45 blocks the outdoor air flowing into the interior of the subject vehicle 40 by controlling the air conditioner 42 before the subject vehicle 40 reaches the expected entry time.

In this case, the subject vehicle control unit 45 controls the power window driving unit 421 to close the power window, and controls the damper unit 422 to switch to the betting mode. As described above, by blocking the outdoor air with the air conditioner 42 before the expected entry time is reached, the outdoor air of the air-contaminated area does not flow into the interior of the vehicle 40 .

Accordingly, in a state in which the outdoor air is blocked by controlling the air conditioner 42 , the own vehicle controller 45 controls the outdoor air sensor 43 of the own vehicle to detect the air pollution level of the outdoor air of the own vehicle 40 . . The subject vehicle control unit 45 determines whether the air pollution degree of the outdoor air detected by the outdoor air sensor 43 of the subject vehicle is included within a preset first set range, and as a result of the determination, the outdoor air air pollution degree is within the first set range. If it is not included within the range, the air conditioner 42 is returned to the state before receiving the previously stored air pollution area setting information.

Meanwhile, in a state in which the outdoor air is blocked by controlling the air conditioner 42 , the indoor air inside the vehicle 40 may be polluted.

Accordingly, in a state in which the outdoor air is cut off, the subject vehicle controller 45 controls the indoor air sensor 44 of the subject vehicle to sense the indoor air of the subject vehicle 40 . The subject vehicle control unit 45 determines whether the air pollution degree of the indoor air sensed by the indoor air sensor 44 of the subject vehicle is included within a second preset range. As a result of the determination, if the air pollution degree of the indoor air is within the second set range, the vehicle controller 45 controls the air purifier 60 to purify the indoor air of the vehicle 40 .

That is, the vehicle control unit 45 cuts off the outdoor air through the air conditioner 42 before the expected entry time is reached, so that the outdoor air of the air-contaminated area is supplied to the interior of the vehicle 40 by the vehicle 40 . Do not let it get inside.

In a state in which the outdoor air is blocked by controlling the air conditioner 42 , the subject vehicle controller 45 controls the outdoor air sensor 43 of the subject vehicle to detect an air pollution degree of the outdoor air of the subject vehicle 40 .

In this case, the subject vehicle control unit 45 restores the operating state of the power window and damper unit 422 to the state before the air pollution area setting information is input according to the air pollution degree of the outdoor air (S124).

For example, the vehicle control unit 45 determines whether the outdoor air pollution level detected by the vehicle outdoor air sensor 43 is within a preset first set range, and as a result of the determination, the outdoor air air pollution level is If it is not included within the first setting range, the air conditioner 42 is returned to the state before receiving the previously stored air pollution area setting information.
