[0091] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0092] Figure 1 The flowchart of the first embodiment of the vehicle function control method based on air quality of the present invention is shown, and the method is executed by the vehicle function control device based on air quality. Figure 1 As shown, the method comprises the following steps:

[0093] In an optional manner, the vehicle function control device based on air quality may be an on-board intelligent cockpit system.

[0094] Step 110: Acquire the driving position data of the vehicle.

[0095] Among them, the driving position data is generated by retrieving the vehicle's GPS positioning data.

[0096] Step 120: Identify the vehicle position based on the driving position data, and perform in-vehicle air conditioning when the vehicle reaches an area corresponding to an abnormal location; wherein the abnormal location is: a location where the gas data outside the vehicle is abnormal.

[0097] In an optional manner, based on the collected gas concentration outside the vehicle, an area corresponding to the abnormal location is set, and the area is: a circular area with the abnormal location as the center and the shielding effective distance as the radius.

[0098] In an optional manner, when the vehicle arrives at the area corresponding to the abnormal location, performing in-vehicle air conditioning includes:

[0099] Obtaining a shielding effective distance; wherein obtaining the shielding effective distance comprises: calculating the shielding effective distance based on the gas data outside the vehicle; or, using a preset shielding effective distance sample value as the shielding effective distance;

[0100] When the distance between the vehicle and the abnormal location is the shielding effective distance, it is determined that the vehicle has reached the area corresponding to the abnormal location, and the vehicle computer function is called to perform air conditioning in the vehicle; wherein, the vehicle computer function includes: a window closing function and a function of closing the air conditioning circulation system inside and outside the vehicle.

[0101] It is understandable that the shielding effective distance can be set in advance by the user, and Table 1 is provided for illustration:

[0102] Table 1

[0103] Serial number Shielding effective distance sample value 1 50 meters (when the concentration exceeds the threshold range of 0-100%) 2 100 meters (when the concentration exceeds the threshold range of 101% to 300%) 3 200 meters (when the concentration exceeds the threshold range of 301% to 1000%) 4 500 meters (when the concentration exceeds the threshold range and is greater than 1000%) 5 Custom(between 20-1000 meters)

[0104] Among them, when the gas concentration outside the vehicle reaches the relevant threshold range, the shielding effective distance sample value corresponding to the user is recommended by default.

[0105] It is understandable that during the ride, the quality of the external air environment varies. Especially in some common areas, certain special periods or when the roads are crowded, there are a lot of volatile organic compound gases (i.e., the abnormal gases described in the present invention) in the air, which will seriously affect people's emotions and health. If the vehicle drives to the abnormal location and then starts the relevant in-vehicle air circulation mechanism, the abnormal gas may have entered the vehicle or been contacted by the human olfactory organ. When the vehicle drives to the area corresponding to the abnormal location, if the vehicle windows are open, or the windows are closed but the air conditioner in the car is not turned on the internal circulation mode (or other air inside and outside the car is in an exchange state), the passengers in the car will smell the odor of the external environment. If the road is congested, the odor will last longer in the car and be difficult to eliminate.

[0106] In an optional manner, the calculating of the shielding effective distance based on the vehicle external gas data includes:

[0107] Obtain the diffusion coefficient and attenuation coefficient of the abnormal location;

[0108] The shielding effective distance is calculated based on the diffusion coefficient, attenuation coefficient, external gas data, abnormal gas concentration threshold and gas diffusion formula.

[0109] Among them, the gas diffusion formula is specifically:

[0110] C(r)=C0 / (1+ar)*exp[-(r / σ) 2 ]

[0111] Where r is the effective shielding distance, C(r) is the gas concentration at r, σ is the diffusion coefficient, a is the attenuation coefficient, and C0 is the gas data outside the vehicle. The abnormal gas concentration threshold is substituted into the gas concentration at r to calculate the effective shielding distance.

[0112] It should be noted that the attenuation coefficient can be estimated by experimental measurement near the abnormal location or according to an empirical formula. The experimental measurement can be performed by measuring the odor concentration at different distances and calculating the attenuation coefficient based on the measured data. The empirical formula can be estimated based on the existing experimental data or empirical parameters in the literature. The diffusion coefficient can be estimated based on Fick's law or an empirical formula. According to Fick's law, the diffusion coefficient can be calculated by the diffusion coefficient of the odor substance, the molecular mass of the odor substance, the temperature and the dynamic viscosity of the air. The empirical formula can be estimated based on the existing experimental data or empirical parameters in the literature.

[0113] In an optional manner, after performing the in-vehicle air conditioning, the method further includes:

[0114] Obtain environmental data of abnormal locations within a preset time;

[0115] Calculate the gas concentration change rate at the abnormal location based on environmental data and gas concentration change formula;

[0116] Based on the gas concentration change rate and the gas data outside the vehicle, determine the gas concentration change at the abnormal location;

[0117] According to the gas change concentration, diffusion coefficient, attenuation coefficient and gas diffusion formula, the gas diffusion concentration when the vehicle's current distance from the abnormal location is the shielding effective distance is determined, and the mark cancellation operation is performed on the electronic map based on the gas diffusion concentration.

[0118] Among them, the environmental data includes: average temperature, average humidity, average wind speed, diffusion coefficient, gas concentration gradient, wind speed gradient, temperature gradient and humidity gradient; the preset time is specifically: the time difference between the time when the vehicle’s current distance from the abnormal location is the shielding effective distance and the time when the abnormal location is marked.

[0119] Among them, the formula for gas concentration change is:

[0120]

[0121] In the formula, is the rate of change of gas concentration, V is the average wind speed, D is the diffusion coefficient, is the gas concentration gradient, is the wind speed gradient, is the temperature gradient, is the humidity gradient, C is the gas data outside the vehicle, and α, β, and γ are influencing factors.

[0122] By substituting the outside gas data and the preset time into the gas concentration change rate, the gas change concentration can be obtained.

[0123] In an optional manner, the mark cancellation operation includes:

[0124] Summarize the gas diffusion concentration each time the distance between the vehicle and the abnormal location is the shielding effective distance;

[0125] When the gas diffusion concentration is less than the abnormal gas concentration threshold and the number of consecutive times that the gas diffusion concentration is less than the abnormal gas concentration threshold reaches the number threshold, the abnormal location is unmarked.

[0126] In a specific embodiment, the number threshold can be 5 times. When the vehicle passes through the abnormal location for multiple times (greater than or equal to 5 times) and fails to identify the relevant abnormal gas or the gas diffusion concentration is lower than the abnormal gas concentration threshold, the voice prompt assistant can automatically prompt the user whether to cancel the marked point as a fixed pollution point: 1. If the user answers not to cancel, the mark of the abnormal location will be retained, and the judgment will be repeated 5 times. After repeating the recognition 5 times, it will be determined whether to continue to prompt the user according to the actual situation; 2. If the user answers to cancel, the abnormal location mark will be cancelled for this location. When the vehicle passes by the location for multiple times (less than 5 times) in a row, and any time it identifies that the relevant gas diffusion concentration is higher than the abnormal gas concentration threshold, the mark of the abnormal location will be retained by default. In addition to the voice reply, the user can set the cancellation of the mark of the abnormal location in the relevant setting module in the car computer (such abnormal locations that have been prompted are given priority to display the recommendation for cancellation). After cancellation, the location of the location will be re-determined.

[0127] In an optional manner, the vehicle exterior gas data includes: vehicle exterior gas concentration and vehicle exterior gas type; the acquisition of the abnormal location includes:

[0128] Obtaining vehicle external gas data and gas collection location data;

[0129] Matching the gas concentration and type outside the vehicle with the preset abnormal gas library to obtain the matching result corresponding to the gas data outside the vehicle;

[0130] The external gas data with a successful matching result is identified as abnormal gas, and the abnormal location is marked on the electronic map according to the gas collection location data corresponding to the abnormal gas; wherein the external gas data corresponds to the gas collection location data one by one.

[0131] Among them, the abnormal gas library includes: a number of volatile compound types and an abnormal concentration threshold corresponding to each volatile compound type.

[0132] Specifically, a bionic olfactory chip or related submodule (this embodiment uses a bionic olfactory sensor) for detecting trace gases and volatile organic compound odor molecules in the air is added to the vehicle air quality sensor module. When the submodule detects that the relevant indicators of the air outside the vehicle are rapidly increasing or abnormal, the signal is transmitted to the vehicle intelligent cockpit system, and the vehicle intelligent cockpit system locates the location based on the detection signal combined with the vehicle map. The vehicle intelligent cockpit system automatically prompts the user through the system voice or system HMI interface whether to mark the location as an abnormal location and save the location marking configuration.

[0133] It is understandable that the vehicle-mounted intelligent cockpit system can automatically mark abnormal locations, and can also prompt the user whether to mark the current location of the vehicle as an abnormal location by calling the system voice / vehicle map function. If the user confirms, the coordinates of the location will be marked as an abnormal location on the map in the vehicle cockpit system.

[0134] For better explanation, the abnormal gas library can be found in Table 1. In addition to the types of volatile compounds and abnormal concentration thresholds, the abnormal gas library also includes chemical formulas:

[0135] Table 2

[0136] Serial number Types of volatile compounds Chemical formula Abnormal concentration threshold (greater than or equal to) 1 Volatile organic gases VOC 0.5mg / m3 2 Methyl mercaptan CH4S 0.004mg / m3 3 Ammonia NH3 1.0mg / m3 4 Carbon disulfide CS2 2.0mg / m3 5 Hydrogen sulfide H2S 0.03mg / m3 6 Styrene C8H8 3.0mg / m3 7 Foul smell OU 10-500 (dimensionless) 8 Trimethylamine C2H9 0.05mg / m3 9 Methyl sulfide C2SH6 0.03mg / m3 10 Dimethyl disulfide C2H6S2 0.03mg / m3

[0137] In a specific embodiment, the concentration of gas outside the vehicle and the type of gas outside the vehicle are matched with a preset abnormal gas library to obtain a matching result corresponding to the gas data outside the vehicle. Specifically, the on-board intelligent cockpit system determines whether the type of gas outside the vehicle corresponds to the type of volatile compound in the abnormal gas library. If so, it determines whether the concentration of gas outside the vehicle is greater than or equal to the abnormal concentration threshold corresponding to the type of volatile compound. If so, it can be considered that the match is successful, and the gas outside the vehicle can be considered as abnormal gas.

[0138] In an optional manner, the present invention further comprises:

[0139] Respond to user's operation instructions;

[0140] When the operation instruction is to mark an abnormal location, the abnormal location is marked on the electronic map based on the current location of the vehicle;

[0141] When the operation instruction is to cancel the mark of an abnormal location, the mark of the nearest abnormal location is cancelled on the electronic map based on the current location of the vehicle.

[0142] It is understandable that when the bionic olfactory sensor does not identify abnormal gas and the user feels that there is an odor in the area, the user can actively mark the location as the area where the odor is located. The next time the vehicle approaches or passes through the area again, the windows or related air-conditioning systems can be automatically adjusted to prevent the exchange of outside air into the vehicle. At the same time, this principle can be analogized to when the ambient air quality is monitored to be extremely good, and the user is automatically prompted to open the window for ventilation. The specific operations are: (1) manually wake up the voice system of the on-board intelligent cockpit system, and input voice commands (for example: find air abnormalities, mark as abnormal locations, etc.) into the on-board intelligent cockpit system, that is, mark the coordinates of the location as an abnormal location on the map in the on-board intelligent cockpit system; (2) The user long presses the HMI map module in the cockpit system to start the shielding point marking function, that is, mark the coordinates of the location as an abnormal location on the map in the on-board intelligent cockpit system.

[0143] The embodiment of the present invention identifies whether the vehicle has traveled to the location where abnormal gas exists based on the collected gas data outside the vehicle and the gas collection location data, and performs air conditioning in the vehicle after confirming that it has arrived at the abnormal location. The present invention can avoid the problem of odor entering the vehicle due to untimely air conditioning in the vehicle by prompting the location where abnormal gas exists, improve the efficiency of air conditioning in the vehicle, and solve the cleaning problem caused by odor entering the vehicle compartment in the prior art. Further, the present invention sets the shielding effective distance for the diffusion of abnormal gas, so that the vehicle can perform air conditioning in the vehicle in advance when passing the abnormal location again, thereby avoiding abnormal gas from entering the vehicle in advance, and improves the accuracy of setting the shielding effective distance based on gas diffusion. Further, the present invention combines gas concentration changes and gas diffusion. After the air conditioning in the vehicle, by judging whether the abnormal gas concentration at the abnormal location is less than the abnormal gas concentration threshold after the change with time and distance and whether the continuous number of times less than the abnormal gas concentration threshold reaches a preset value, the cancellation mark of the abnormal location is comprehensively judged, making the cancellation of the abnormal location more intelligent.

[0157] Step 221: The effective distance is configurable, and jump to 222.

[0158] Step 222: The vehicle drives to the vicinity of the marking point again and jumps to 223.
