As shown in FIG. 3, in the embodiment, the air cleaning unit 32 is installed inside the vehicle 2. The central armrest enables the air cleaning unit 32 to filter harmful substances (such as bacteria, aerosols or organic compounds) in the air of the vehicle to maintain the quality of the interior environment. However, the present invention is not limited thereto, and the air cleaning unit 32 may be disposed at other positions inside the vehicle 2 (such as an instrument panel).

The controller 40 may specifically be a PI controller or a PID controller and installed inside the vehicle 2 (as shown in FIG. 3 ). The controller 40 is connected to the camera module 10 , the radar module 20 , and the air . The module 30 is adjusted. For example, the controller 40 can be connected to the camera module 10, the radar module 20, and the air conditioning module 30 via a wired device (such as a Controller Area Network) or a wireless device (such as Wifi, Bluetooth, or ZigBee) to transmit signals or data to each other. .

The controller 40 can receive at least one of the front vehicle image D1 or the front vehicle distance D2 and correspondingly output the control command D3 to the air conditioning module 30 to activate the air conditioning module 30 to maintain the air in the vehicle 2 . quality. In other words, the controller 40 can select at least one of the front vehicle image D1 output by the camera module 10 or the front vehicle distance D2 output by the radar module 20 as a determination of whether to output the control command D3 to the air. The basis of the adjustment module 30. In detail, the controller 40 can determine whether to output the control command D3 according to the preceding vehicle image D1 or the preceding vehicle distance D2, or the controller 40 can simultaneously determine whether to output the control command D3 according to the preceding vehicle image D1 and the preceding vehicle distance D2. This further example is as follows: As shown in FIG. 4, in the present embodiment, when the vehicle 2 has other vehicles in front of the driving process, the radar module 20 can detect the preceding vehicle distance D2 (for example, 20 meters) and transmit it to the controller. 40, and the controller 40 may output the control command D3 to the air conditioning module 30 when the preceding vehicle distance D2 is less than a set value. For example, the set value is 25 meters, and the front vehicle distance D2 is 20 meters. At this time, the controller 40 outputs the control command D3. On the other hand, if the front vehicle distance D2 is 30 meters, the controller 40 does not output the control command D3. The above control command D3 can activate the air conditioning module 30 to switch the air conditioning unit 31 is an internal air circulation mode, which prevents the exhaust gas discharged from the preceding vehicle from entering the vehicle 2 in advance to maintain the environmental quality inside the vehicle. In other embodiments, the control command D3 may also activate only the air cleaning unit 32 of the air conditioning module 30, or the control command D3 may simultaneously activate the air conditioning unit 31 of the air conditioning module 30 to switch to the internal air circulation mode and open. The air cleaning unit 32 operates, which is not limited.

As shown in FIG. 6 , in the embodiment, when the vehicle 2 has other vehicles in front of the driving process, the camera module 10 can capture the preceding vehicle image D1 and output to the controller 40, and the controller 40 When the front vehicle image D1 is received, it is determined that there are other vehicles ahead and the control command D3 is output. Alternatively, the controller 40 outputs the control command D3 when the front vehicle image D1 is greater than the preset range R. Since a large vehicle (such as a large truck or a linked vehicle) is mostly a diesel engine, it is easy to discharge a large amount of exhausted air. Therefore, In this embodiment, the preset range R can be preset to the size range of the large vehicle (the square range in the figure), and when the size of the current vehicle image D1 exceeds the boundary of the preset range R, it can be determined that the preceding vehicle is a large vehicle. Output control command D3. The control command D3 can activate the air conditioning module 30 to switch the air conditioning unit 31 to the internal air circulation mode, so as to prevent the exhaust gas discharged from the preceding vehicle from entering the vehicle 2 in advance to maintain the quality of the interior environment of the vehicle. However, the present invention is not limited thereto. In some embodiments, the preset range R may be freely defined and is not limited to a frame shape or a preset size range of a large vehicle. For example, the preset range R may also be a boundary line of two intervals.

Alternatively, in some embodiments, the controller 40 may also determine whether to output the control command D3 according to the preceding vehicle image D1 and the preceding vehicle distance D2. For example, the controller 40 determines that the vehicle is a large vehicle based on the preceding vehicle image D1, and the front vehicle distance D2 is less than 30 The control command D3 is output only at the time of the rule.

In addition, as shown in FIG. 2 , the air quality control device 1 further includes a speed detecting module 50 , which may be a speed sensor and is connected to the controller 40 and the vehicle 2 . The axle 40 detects the current traveling speed D4 of the vehicle 2 (for example, 10 kmh, 20 kmh or 50 kmh), and the controller 40 further receives the driving speed D4 and more selectively outputs the control command D3 corresponding to the traveling speed D4, that is, the controller 40 It may be determined whether to output the control command D3 based on the preceding vehicle image D1 and the traveling speed D4, or whether to output the control command D3 based on the preceding vehicle distance D2 and the traveling speed D4. For example, in an embodiment, if the driving speed D4 is less than a speed value (for example, the speed value is 10 kmh and the traveling speed D4 is 5 kmh), the controller 40 can determine that the vehicle 2 is currently in a traffic jam state or a low speed driving state. At this time, the controller 40 outputs the control command D3 as long as it receives the preceding vehicle image D1 (that is, indicates that there is another vehicle ahead). The reason is that when the vehicle is jammed, the distance between the vehicle 2 and the preceding vehicle is relatively close, so that the pollutants of the preceding vehicle are easier to enter the vehicle 2, so the controller 40 outputs the above control command D3 regardless of whether the front vehicle image D1 is a large vehicle or a small vehicle. . Alternatively, in another embodiment, if the front vehicle distance D2 is less than the set value, but the traveling speed D4 is greater than a speed value (eg, the speed value is 60 kmh, and the traveling speed D4 is 70 kmh), it can be determined that the vehicle 2 is currently At the high speed running state, at this time, the controller 40 does not output the control command D3. The reason is that although the distance between the vehicle 2 and the preceding vehicle is less than the set value, when the vehicle 2 is in the high speed state, the flow rate of the outside air is relatively fast, so that the pollutant of the preceding vehicle is less likely to enter the vehicle 2.

As shown in FIG. 2, in the present embodiment, the air quality control device 1 Further, an internal air quality sensor 60 is disposed inside the vehicle 2 and connected to the controller 40 to detect the air quality in the vehicle and output an air quality monitoring value D6. As shown in FIG. 3, in the present embodiment, the air quality control device 1 includes two internal air quality sensors 60 and is installed in the air conditioning unit 31 and the air cleaning unit 32, respectively, for the air quality monitoring. The value D6 may refer to a concentration value of a gas such as suspended particles, carbon monoxide, and carbon dioxide inside the vehicle 2.

The controller 40 selectively outputs the start command D5 to open the air cleaning unit 32 corresponding to the air quality monitoring value D6. That is, the controller 40 determines whether to output the start command D5 to correspond to the open air cleaning unit 32 based on the air quality monitoring value D6. For example, the controller 40 may output a start command D5 to turn on the air cleaning unit 32 to purify the interior air when the aerosol concentration shown by the air quality monitoring value D6 is greater than 1 ppm.

As shown in the second and third embodiments, in the present embodiment, the air quality control device 1 further includes an external air quality sensor 70 disposed at an air inlet 5 in front of the exterior of the vehicle 2 and connected to the controller 40 for detecting An external air value D7 is output, but is not limited thereto. In other embodiments, the outer air quality sensor 70 may also be mounted on the front light or hood of the vehicle 2. The outside air value D7 may refer to a concentration value of a gas such as suspended particles, carbon monoxide, and carbon dioxide of the air outside the vehicle 2. The controller 40 can also output the above control command D3 when the external air value D7 is greater than a predetermined value (for example, the carbon monoxide concentration in the external air value D7 is 3 ppm, and the preset value is 1 ppm). For example, when the outside air of the vehicle 2 is not good (such as damaging) or the exhaust gas is generated in front of the burning article, causing the external air value D7 to be greater than a preset value, the controller 40 That is, the control command D3 is output, and the air conditioning unit 31 that activates the air conditioning module 30 is switched to the internal air circulation mode to instantly prevent external exhaust gas from entering the vehicle 2 to maintain the quality of the interior environment of the vehicle.

In summary, the creation controller can open the air conditioning before the vehicle enters the vehicle in advance according to the information of the preceding vehicle detected by the front vehicle detection module (such as the image of the preceding vehicle or the distance of the preceding vehicle). The module maintains the air quality inside the vehicle. For example, the air conditioner is switched to the internal air circulation mode to prevent pollution from entering the vehicle, or the air cleaner in the vehicle is activated to maintain the air quality in the vehicle to prevent disease.
