Description

Technical Field

[0001] The present invention relates to the technical field of automobile air purification, and in particular to a high-efficiency automobile air purification method and system. Background Art

[0002] With the significant increase in car ownership and growing public awareness of health, in-car air quality is gaining increasing attention from automakers and consumers, leading to the emergence of in-car air purification systems. Existing in-car air purification systems include dual-channel PM2.5 sensors, air quality sensors, and air purifiers. These systems use sensors to detect PM2.5 levels and air quality concentrations inside and outside the vehicle. Based on the air quality, they activate the air conditioner's blower, negative ion generator, and internal and external recirculation dampers to purify the air inside the vehicle.

[0003] However, existing vehicle air purification systems have the following problems: the internal and external circulation dampers are switched arbitrarily without considering the air conditioning setting status. For example, switching to external circulation in hot weather affects the comfort in the car; in the humid weather in spring and autumn, switching to internal circulation can easily cause the windows to fog up, affecting driving safety; frequently turning on the air purifier affects the service life of the parts, resulting in a high replacement frequency. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a method and system for efficiently purifying automobile air.

[0005] The present invention adopts the following technical solution: a method for efficiently purifying automobile air, the method comprising:

[0006] Step 1: Obtain vehicle status, interior air quality status, interior temperature, exterior air quality status, exterior temperature, and air conditioning setting status;

[0007] Step 2: When the air quality in the vehicle is not good, if the air conditioner is off, turning on the air conditioner blower and the negative ion generator;

[0008] Step 3: If the air conditioner is on and the vehicle is in remote start mode, the negative ion generator is turned on or off and the internal and external circulation damper states are switched based on the air conditioner setting state and the outside air quality state; wherein the air conditioner setting state is one-touch cooling or one-touch heating;

[0009] Step 4. If the air conditioner is on and the vehicle is not in remote start state, the negative ion generator is turned on or off and the internal and external circulation damper states are switched based on the air conditioner setting state, the outside air quality state, the inside temperature and the outside temperature; wherein the air conditioner setting state is automatic AUTO mode, defrost mode, and air conditioner blower gear.

[0010] An efficient automobile air purification method according to an embodiment of the present invention timely switches the internal and external circulation dampers by combining multiple variable factors such as the vehicle status, the air quality status inside the vehicle, the temperature inside the vehicle, the air quality status outside the vehicle, the temperature outside the vehicle, and the air conditioning setting status, and selectively and automatically turns on the negative ion generator and the air conditioning blower.

If the T-box module does not receive the remote start command sent by the client and the vehicle is in the start state, the vehicle status is non-remote start.

[0013] Obtaining a real-time PM2.5 index inside the vehicle; when the real-time PM2.5 index inside the vehicle is greater than or equal to a preset PM2.5 index threshold, the air quality status inside the vehicle is non-excellent; when the real-time PM2.5 index inside the vehicle is less than the PM2.5 index threshold, the air quality status inside the vehicle is excellent;

[0014] Obtaining a real-time PM2.5 index outside the vehicle; when the real-time PM2.5 index outside the vehicle is greater than or equal to the PM2.5 index threshold, the air quality outside the vehicle is considered non-excellent; when the real-time PM2.5 index outside the vehicle is less than the PM2.5 index threshold, the air quality outside the vehicle is considered excellent;

[0015] The vehicle interior temperature and the vehicle exterior temperature are respectively acquired according to the vehicle interior temperature sensor and the ambient temperature sensor; and the air conditioning setting state is acquired according to the air conditioning control module.

[0016] Furthermore, the method further comprises:

[0024] If the quality of the air outside the vehicle is not good, the working state of the internal and external circulation damper is maintained unchanged, and the negative ion generator is turned on.

[0025] Furthermore, the step 4 includes:

[0026] When the air conditioner setting state is the automatic AUTO mode, the difference between the vehicle interior temperature and the air conditioner set temperature is less than or equal to a preset temperature difference threshold, and the automatic AUTO mode is not in the defrost mode;

[0027] If the outside air quality is good, detecting the working state of the internal and external circulation damper;

[0028] If the working state of the internal and external circulation damper is internal circulation, the working state of the internal and external circulation damper is switched to external circulation;

[0033] Furthermore, the step 4 further includes:

[0034] When the air conditioning setting state is non-automatic AUTO mode, the air conditioning setting state is the defrost mode, or the outside temperature is greater than the preset first ambient temperature threshold and the air conditioning blower gear is greater than the preset gear threshold, or the outside temperature is lower than the preset second ambient temperature threshold and the air conditioning blower gear is greater than the preset gear threshold, the working state of the internal and external circulation damper is maintained unchanged, and the negative ion generator is turned on.

[0035] Furthermore, the step 4 further includes:

[0056] Example 1

[0057] Reference Figures 1 to 2 The first embodiment of the present invention is a method for efficiently purifying automobile air, the method comprising:

[0058] Step 1: Obtain the vehicle status, interior air quality status, interior temperature, exterior air quality status, exterior temperature, and air conditioning setting status, including:

[0059] The vehicle status is determined based on whether the T-box module in the car receives the remote start command sent by the client. If the T-box module receives the remote start command sent by the client, the vehicle status is remote start. If the T-box module does not receive the remote start command sent by the client and the car is in the start state, the vehicle status is non-remote start.

[0060] Get the real-time PM2.5 index inside the vehicle. When the real-time PM2.5 index inside the vehicle is greater than or equal to the preset PM2.5 index threshold, the air quality inside the vehicle is not good; when the real-time PM2.5 index inside the vehicle is less than the PM2.5 index threshold, the air quality inside the vehicle is good.

[0061] Get the real-time PM2.5 index outside the vehicle. When the real-time PM2.5 index outside the vehicle is greater than or equal to the PM2.5 index threshold, the air quality outside the vehicle is not good. When the real-time PM2.5 index outside the vehicle is less than the PM2.5 index threshold, the air quality outside the vehicle is good.

[0062] The vehicle's interior temperature and exterior temperature are acquired based on the vehicle's interior temperature sensor and ambient temperature sensor, respectively; and the air conditioning setting status is acquired based on the air conditioning control module.

[0063] In this embodiment, only the in-car PM2.5 sensor is set to detect the real-time PM2.5 index inside the car. The real-time PM2.5 index outside the car is obtained through the interaction between the IVI host control module and the cloud, which can effectively reduce the cost of using the sensor; the PM2.5 index threshold value is 75ug / m 3 .

[0064] Step 2: When the air quality in the vehicle is not good, if the air conditioner is off and the vehicle is in remote start mode, the air conditioner blower and negative ion generator will be turned on; if the vehicle is not in remote start mode, a voice announcement will be made through the IVI system to remind you to start air purification.

[0065] When the air quality in the vehicle is excellent and the vehicle status is not remote start, the working status of the air conditioner is not considered, the air conditioner blower status is maintained unchanged, and the working status of the negative ion generator is detected at the same time; if the working status of the negative ion generator is on, the negative ion generator is turned off; if the working status of the negative ion generator is off, the working status of the negative ion generator is maintained unchanged.

[0066] Step 3. If the air conditioner is on and the vehicle is in remote start mode, the negative ion generator is turned on or off and the internal and external circulation damper states are switched based on the air conditioner setting state and the air quality outside the vehicle; the air conditioner setting state is one-button cooling or one-button heating.

[0067] When the air conditioner is set to one-button cooling or one-button heating, the working status of the internal and external circulation dampers will remain unchanged, and the working status of the negative ion generator will be detected at the same time; if the working status of the negative ion generator is on, the working status of the negative ion generator will remain unchanged; if the working status of the negative ion generator is off, the negative ion generator will be turned on.

[0068] When the air conditioning setting is not one-touch cooling or one-touch heating, if the outside air quality is good, the working state of the internal and external circulation dampers is detected; if the working state of the internal and external circulation dampers is internal circulation, the working state of the internal and external circulation dampers is switched to external circulation; if the working state of the internal and external circulation dampers is external circulation, the working state remains unchanged;

[0069] If the air quality outside the vehicle is not good, the working status of the internal and external circulation dampers will be maintained unchanged, and the working status of the negative ion generator will be detected at the same time; if the working status of the negative ion generator is on, the working status of the negative ion generator will be maintained unchanged; if the working status of the negative ion generator is off, the negative ion generator will be turned on.

[0070] Step 4. If the air conditioner is on and the vehicle is not in remote start mode, the negative ion generator is turned on or off and the internal and external circulation damper status is switched based on the air conditioner setting status, the outside air quality status, the inside temperature and the outside temperature; among which, the air conditioner setting status is automatic AUTO mode, defrost mode, and air conditioner blower gear.

[0071] When the air conditioner is set to AUTO mode, the difference between the vehicle interior temperature and the air conditioner set temperature is less than or equal to the preset temperature difference threshold, and the AUTO mode is not in defrost mode;

[0072] If the air quality outside the vehicle is good, the working state of the internal and external circulation damper is detected; if the working state of the internal and external circulation damper is internal circulation, the working state of the internal and external circulation damper is switched to external circulation; if the working state of the internal and external circulation damper is external circulation, the working state is maintained unchanged;

[0073] If the air quality outside the vehicle is not good, the working status of the internal and external circulation dampers will be maintained unchanged, and the working status of the negative ion generator will be detected at the same time; if the working status of the negative ion generator is on, the working status of the negative ion generator will be maintained unchanged; if the working status of the negative ion generator is off, the negative ion generator will be turned on.

[0074] In this embodiment, the temperature difference threshold is 5°C.

[0075] When the air conditioning setting state is automatic AUTO mode, and any of the conditions is met, that is, the difference between the temperature inside the vehicle and the air conditioning setting temperature is greater than the preset temperature difference threshold or the automatic AUTO mode is in defrost mode, the working state of the internal and external circulation dampers will be maintained unchanged, and the working state of the negative ion generator will be detected at the same time; if the working state of the negative ion generator is on, the working state of the negative ion generator will be maintained unchanged; if the working state of the negative ion generator is off, the negative ion generator will be turned on.

[0076] When the air conditioning setting state is non-automatic AUTO mode, and any of the following conditions are met: the air conditioning setting state is defrost mode, the outside temperature is greater than the preset first ambient temperature threshold and the air conditioning blower gear is greater than the preset gear threshold (A / C cooling is on), and the outside temperature is lower than the preset second ambient temperature threshold and the air conditioning blower gear is greater than the preset gear threshold, the working state of the internal and external circulation dampers will be maintained unchanged, and the working state of the negative ion generator will be detected at the same time; if the working state of the negative ion generator is on, the working state of the negative ion generator will be maintained unchanged; if the working state of the negative ion generator is off, the negative ion generator will be turned on.

[0077] In this embodiment, the first ambient temperature threshold is 30°C, the gear threshold is 3, and the second ambient temperature threshold is 0°C.

[0078] If the air conditioner is set to non-defrost mode, or the outside temperature is less than or equal to the preset first ambient temperature threshold, or the air conditioner blower gear is less than or equal to the preset gear threshold, or the outside temperature is greater than or equal to the preset second ambient temperature threshold, or the air conditioner blower gear is less than or equal to the preset gear threshold;

[0079] If the air quality outside the vehicle is good, the working state of the internal and external circulation damper is detected; if the working state of the internal and external circulation damper is internal circulation, the working state of the internal and external circulation damper is switched to external circulation; if the working state of the internal and external circulation damper is external circulation, the working state is maintained unchanged;

[0080] If the air quality outside the vehicle is not good, the working status of the internal and external circulation dampers will be maintained unchanged, and the working status of the negative ion generator will be detected at the same time; if the working status of the negative ion generator is on, the working status of the negative ion generator will be maintained unchanged; if the working status of the negative ion generator is off, the negative ion generator will be turned on.

[0081] An efficient automobile air purification method according to an embodiment of the present invention timely switches the internal and external circulation dampers by combining multiple variable factors such as the vehicle status, the air quality status inside the vehicle, the temperature inside the vehicle, the air quality status outside the vehicle, the temperature outside the vehicle, and the air conditioning setting status, and selectively and automatically turns on the negative ion generator and the air conditioning blower. While efficiently purifying the air inside the vehicle, it ensures the comfort of the air conditioning and driving safety inside the vehicle, extends the service life of the negative ion generator, reduces the replacement frequency of the negative ion generator, and achieves the effect of efficiently and accurately purifying the air inside the vehicle.

[0082] Example 2

[0083] Reference Figure 3 The second embodiment of the present invention is a high-efficiency automobile air purification system, which includes: a T-box module, an IVI control system, and an air conditioning control system. The IVI control system includes an IVI display screen and an IVI host control module. The air conditioning control system includes an air conditioning box assembly, an air conditioning control module, an in-vehicle PM2.5 sensor, a negative ion generator, an in-vehicle temperature sensor, and an ambient temperature sensor.

[0084] The T-box module is used to receive the remote start command sent by the client and send the remote start command to the IVI host control module through the CAN bus;

[0085] The IVI host control module is used to interact with the cloud to obtain the real-time PM2.5 index outside the vehicle's location, and is used to recognize air purification voice commands and voice prompts to start the air purification system. It also sends the air purification voice commands and remote start commands to the air conditioning control module via the CAN bus;

[0086] The IVI display is used to display the air conditioning setting status and the real-time PM2.5 index inside the vehicle and outside the vehicle;

[0087] The air conditioning box assembly includes the air conditioning blower, internal and external circulation dampers, mode dampers and heating and cooling dampers;

[0088] The air conditioning control module is used to control the operation of the air conditioning box assembly. The air conditioning control module is used to control the PM2.5 sensor in the car to detect the current real-time PM2.5 index in the car, control the temperature sensor in the car to detect the current temperature in the car, control the ambient temperature sensor to detect the current temperature outside the car, and is used to receive the current air conditioning setting status, outside temperature, inside temperature, real-time PM2.5 index in the car and real-time PM2.5 index outside the car to control the opening or closing of the negative ion generator and the switching status of the internal and external circulation dampers, and send the real-time PM2.5 index in the car and the air conditioning setting status to the IVI host control module through the CAN bus.

[0089] In this embodiment, when the user sends a remote start command to the T-box module through the mobile phone APP to remotely start the vehicle, the air conditioning control module controls the PM2.5 sensor in the car after receiving the remote start command sent by the IVI host control module, obtains the real-time PM2.5 index in the car, and judges the air quality status in the car. If the air quality status in the car is good, the PM2.5 index in the car is continuously detected; if the air quality status in the car is polluted, including light, moderate, heavy, and severe levels, and the air conditioner is remotely started, it is judged whether the remote air conditioning setting status is One-touch cooling or one-touch heating, if yes, the negative ion generator working status is detected and turned on, while the internal and external circulation damper status remains unchanged. If not, the real-time PM2.5 index outside the car is sent by the IVI host control module, and the air quality status outside the car is judged, and the current internal and external circulation damper status is detected to perform corresponding actions. If the air quality status outside the car is excellent and the current internal circulation is switched to external circulation, the internal and external circulation dampers will be switched to external circulation, otherwise the negative ion generator will be started; if the air conditioner is not turned on remotely and the car is in a polluted state, the air conditioner blower and negative ion generator will be automatically turned on.

[0090] When the vehicle is driving normally or in other non-remote start states, the air conditioning control module controls the PM2.5 sensor in the car to obtain the real-time PM2.5 index in the car and judge the air quality status in the car. If the air quality status in the car is excellent, the air conditioning blower and the internal and external circulation dampers are maintained at their current states, and the negative ion generator is turned off if it is turned on; if the air quality status in the car is polluted, including mild, moderate, severe, and serious levels, if the air conditioning is not currently turned on, the IVI host control module will make a voice announcement to remind the user that the air purification system will be automatically turned on. At the same time, the IVI display will pop up a box to prompt the current air pollution index in the car, and the air conditioning control module will automatically turn on the air conditioning blower and negative ion generator. If the air conditioning is currently turned on, it will be determined whether the current air conditioning setting state is automatic AUTO mode.

[0091] If it is in automatic AUTO mode, and the difference between the air conditioning set temperature and the temperature inside the car is less than or equal to 5 degrees and the mode is non-defrost mode, the air quality status outside the car is judged according to the real-time PM2.5 index outside the car, and the current internal and external circulation damper status is detected to perform corresponding actions. If the air quality status outside the car is in good status and the current internal circulation is in internal circulation, the internal and external circulation dampers are switched to external circulation. If the air quality status outside the car is in polluted status, the negative ion generator is turned on and the internal and external circulation dampers remain unchanged. If this condition is not met, the negative ion generator is turned on and the internal and external circulation dampers remain unchanged.

[0092] If the current air conditioning setting state is non-automatic AUTO mode and any of the following conditions is met: the air conditioning is in defrost mode, the ambient temperature is greater than 30 degrees & A / C cooling is turned on & the air conditioning blower gear is greater than gear 3, the ambient temperature is less than 0 degrees & the air conditioning blower gear is greater than gear 3, then the negative ion generator is turned on and the internal and external circulation damper states remain unchanged. If any of the above conditions are not met, the outside air quality state is judged according to the real-time PM2.5 index outside the vehicle, and the current internal and external circulation damper states are detected to perform corresponding actions. If the outside air quality state is in good state and the current state is internal circulation, the internal and external circulation dampers are switched to external circulation. If the outside air quality state is polluted, the negative ion generator is turned on and the internal and external circulation dampers remain unchanged.

[0093] An efficient automobile air purification system according to an embodiment of the present invention timely switches the internal and external circulation dampers by combining multiple variable factors such as the vehicle status, the air quality status inside the vehicle, the temperature inside the vehicle, the air quality status outside the vehicle, the temperature outside the vehicle, and the air conditioning setting status, and selectively and automatically turns on the negative ion generator and the air conditioning blower. While efficiently purifying the air inside the vehicle, it ensures the comfort of the air conditioning and driving safety inside the vehicle, extends the service life of the negative ion generator, reduces the replacement frequency of the negative ion generator, and achieves the effect of efficiently and accurately purifying the air inside the vehicle.
