[0060] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0061] Please also read Figure 1-2 , Figure 1 is a schematic diagram of the structure of a control system of a vehicle provided in an embodiment of the present application; Figure 2 is a flow chart of a vehicle control method provided by an embodiment of the present application. The present application provides a vehicle control method, the control method is applied to Figure 1 The control system 100 of the vehicle shown in the figure, the control method is used to control the opening and closing device 10 on the vehicle to open or close. The opening and closing device 10 may include one or more of a vehicle window, a skylight and a roof.

[0062] like Figure 2 As shown, the control method comprises the following steps:

[0063] Step S1, determining that the air in which the vehicle is located is at a pollution level;

[0064] Step S2, controlling the opening and closing device 10 of the vehicle to close.

[0065] The vehicle control method provided in the present application controls the opening and closing device 10 to close when it is determined that the air in the vehicle is at a pollution level. In this way, when the vehicle encounters smog weather during driving, the opening and closing device 10 can be controlled to close automatically without the need for manual operation by the driver. The intelligence level and driving safety are higher, and the driving experience is better.

[0066] In some embodiments, the air quality is determined based on air parameters, which include: PM2.5 concentration value, PM10 concentration value, SO2 concentration value, NO2 concentration value, CO concentration value, O3 concentration value and one or more of weather information.

[0067] Among them, PM2.5 refers to particles in the air with a diameter less than or equal to 2.5 microns, also known as fine particles or micro-particles. Because its diameter is very small, only about 1 / 30 of the diameter of human hair, these particles can be suspended in the air for a long time, and can penetrate into the alveoli of the lungs, and even enter the blood circulation, affecting human health. The PM2.5 sensor 20 is used to collect information about particulate matter in the air and obtain the PM2.5 concentration value. When there is severe weather such as haze weather and sandstorms, the PM2.5 concentration value in the air will increase significantly. Therefore, the PM2.5 concentration value is usually used as an important indicator for measuring air quality. Similarly, PM10 concentration value, SO2 concentration value, NO2 concentration value, CO concentration value and O3 concentration value can also be used as important indicators for measuring air quality. In addition, the air quality in the environment can also be determined based on weather information. For example, when the air in which the vehicle is located will have haze weather, it can also be determined that the air in which the vehicle is located is at a pollution level.

[0068] In some embodiments, the air parameter includes: a PM2.5 concentration value. The air quality is determined based on the magnitude relationship between the PM2.5 concentration value and a preset concentration threshold.

[0069] like Figure 1 As shown, in some embodiments, the vehicle also includes a PM2.5 sensor 20, and the PM2.5 sensor 20 is used to collect data representing the PM2.5 value. Preferably, the number of the PM2.5 sensors 20 is multiple, and the PM2.5 concentration value is obtained based on the data collected by multiple PM2.5 sensors.

[0070] Exemplarily, the PM2.5 concentration value is the average value of the PM2.5 values ​​represented by the data collected by the multiple PM2.5 sensors. Of course, the PM2.5 concentration value can also be a statistical value such as the mode or median of the PM2.5 values ​​represented by the data collected by the multiple PM2.5 sensors.

[0071] In this way, the average value of the PM2.5 value represented by the data collected by the multiple PM2.5 sensors is compared with the preset concentration threshold to determine whether the air in the vehicle is at a pollution level, which can eliminate data errors and improve the accuracy of the judgment results.

[0072] Among them, the multiple PM2.5 sensors 20 can all be installed in the vehicle, for example, all installed in the air-conditioning device of the vehicle, or all installed outside the vehicle, or some installed inside the vehicle and some installed outside the vehicle.

[0073] When the PM2.5 concentration in the air exceeds 75 μg / m 3 , it indicates that the air has reached a light pollution level. Therefore, in some embodiments, the preset concentration threshold is 75 μg / m 3 In this way, when the air is slightly polluted, the opening and closing device 10 is controlled to close, which can better protect the health of the driver and passengers.

[0074] In other embodiments, the vehicle may also be provided with only one PM2.5 sensor 20. It is not difficult to understand that, compared with judging whether the air in the environment where the vehicle is located is at a pollution level based on the relationship between the PM2.5 value represented by the data collected by a single PM2.5 sensor 20 and the preset concentration threshold, judging the quality of the air in the environment where the vehicle is located based on the average value of the PM2.5 values ​​represented by the data collected by the multiple PM2.5 sensors 20 can avoid erroneous judgment results due to detection errors or failures of a single PM2.5 sensor 20, and the system has higher accuracy.

[0075] In some embodiments, the multiple PM2.5 sensors collect data at preset time intervals; when the average value of the PM2.5 values ​​represented by the data currently collected by the multiple PM2.5 sensors is greater than or equal to the preset concentration threshold, and the average value of the PM2.5 values ​​represented by the data collected by the multiple PM2.5 sensors remains greater than or equal to the preset concentration threshold for a duration greater than a first preset duration, it is determined that the air in the vehicle is at a pollution level.

[0076] It is not difficult to understand that during driving, when the vehicle passes through an area with a lot of smoke and dust (such as a construction site), the average value of the PM2.5 value represented by the data collected by the multiple PM2.5 sensors 20 may exceed the preset concentration threshold for a short time. When the vehicle leaves the area, the PM2.5 concentration value of the air in the vehicle's environment will return to the excellent range. That is to say, when the average value of the PM2.5 value represented by the data collected by the multiple PM2.5 sensors 20 exceeds the preset concentration threshold for a short time, it does not necessarily mean that haze weather has been encountered, and there is no need to control the opening and closing device 10 to close. Therefore, in this embodiment, when it is determined that the average value of the PM2.5 value represented by the data collected by the multiple PM2.5 sensors remains greater than or equal to the preset concentration threshold for a duration greater than the first preset duration, it is determined that the air in the vehicle is at a pollution level, and then the opening and closing device 10 is controlled to close, which can improve the accuracy of haze weather detection. Among them, the first preset duration can be set by the user as needed, for example, 60s.

[0077] Among them, the duration for which the average value of the PM2.5 value represented by the data collected by the multiple PM2.5 sensors remains greater than or equal to the preset concentration threshold can be obtained by multiplying the continuous cumulative number of times the average value of the PM2.5 value is greater than the preset concentration threshold by the preset time interval.

[0078] Among them, the continuous cumulative number of times that the average value of the PM2.5 value is greater than the preset concentration threshold value refers to the cumulative number of times that the average value of the PM2.5 value calculated for multiple consecutive times is greater than the preset concentration threshold value, that is, when the average value of the PM2.5 value calculated each time is less than the preset concentration threshold value, the cumulative number is reset to zero. Exemplarily, the preset time interval is 1s. If the average value of the PM2.5 value calculated for the 100th time is less than the preset concentration threshold value, the average values ​​of the PM2.5 values ​​calculated from the 101st to the 200th time are all greater than the preset concentration threshold value, and the average value of the PM2.5 value calculated for the 201st time is less than the preset concentration threshold value, then the continuous cumulative number of times that the average value of the PM2.5 value is greater than the preset concentration threshold value is 100 times, that is, the duration for which the average value of the PM2.5 value remains greater than the preset concentration threshold value is 100s.

[0079] In some embodiments, Figure 1 As shown, the weather information acquisition device may be a central control unit 70 in a vehicle.

[0080] The central control unit 70 may include a central control PAD, a weather APP may be installed on the central control PAD, and weather information of the environment in which the vehicle is located may be obtained through the weather APP in the central control PAD.

[0081] In some embodiments, when it is determined based on the information received from the weather information acquisition device that the air in which the vehicle is located will experience smog at a preset time in the future, it is determined that the air in which the vehicle is located is at a pollution level.

[0082] The future preset moment is a moment whose time interval with the current moment is less than or equal to the second preset time length. For example, the second preset time length is 10 minutes, that is, when it is determined according to the weather information that the air in the vehicle will have haze weather in the next 10 minutes, it is determined that the air in the vehicle is at a pollution level. In this way, the opening and closing device 10 can be controlled to close in advance before the haze weather arrives, which has a higher level of intelligence, can further protect the health of the driver and passengers, and further improve the driving experience of the driver and passengers.

[0083] In some embodiments, the vehicle further includes an opening and closing position sensor 50. The controlling the opening and closing device 10 to close includes:

[0084] Controlling the opening and closing position sensor 50 to start and detect the opening and closing state of the opening and closing device 10;

[0085] When it is detected that the opening and closing device 10 is in the open state, the opening and closing device 10 is controlled to be closed.

[0086] Thus, by default, the opening and closing position sensor 50 is in a dormant state or a shutdown state, and only when it is determined that the air in the vehicle is at a pollution level, the opening and closing position sensor 50 is controlled to start, thereby saving system resources and electric energy.

[0087] In some embodiments, after controlling the opening and closing position sensor 50 to start and detect the opening and closing state of the opening and closing device 10, the control method further includes:

[0088] When it is detected that the opening and closing device 10 is in the closed state, the opening and closing device 10 is controlled to continue to maintain the closed state.

[0089] In some embodiments, controlling the opening and closing device 10 to close includes:

[0090] When the current speed of the vehicle is lower than or equal to the preset speed threshold, the opening and closing device 10 is controlled to be closed.

[0091] For example, Figure 1As shown, the vehicle further includes an intelligent integrated power brake (IPB) system, and the intelligent integrated power brake system includes a vehicle speed sensor 90 , through which the current vehicle speed of the vehicle can be acquired.

[0092] According to research, when the vehicle is going too fast, forcibly closing the opening and closing device may cause some problems and risks, such as: 1. Increased air resistance: After closing the opening and closing device, the aerodynamic characteristics of the vehicle will change, which may lead to increased air resistance. This will affect the acceleration performance, fuel efficiency and stability of the vehicle; 2. Increased noise inside the car: After closing the opening and closing device, the sound insulation effect between the interior and the external environment will be reduced, and the noise inside the car may increase, affecting the comfort of the driver and passengers. 3. Changes in the temperature inside the car: After closing the opening and closing device, the temperature inside the car may be affected. When driving at high speed, the airflow outside the car may increase the temperature inside the car, especially in hot weather; 4. Safety hazards: When driving at high speed, if the opening and closing device is not closed firmly, it may suddenly open during driving, which may cause safety hazards. In addition, if the vehicle encounters an emergency and requires emergency braking when driving at high speed, the sudden closing of the opening and closing device may cause a certain degree of injury to the driver and passengers; 5. Difficulty in vehicle control: When driving at high speed, closing the opening and closing device may affect the handling of the vehicle. Especially in the case of crosswind or unstable airflow, the vehicle may shake, and the driver needs to drive more carefully. Therefore, in this embodiment, when it is determined that the current vehicle speed is lower than or equal to the preset speed threshold, the opening and closing device 10 is controlled to close, which can improve driving safety and enhance the driving experience of the driver and passengers. The preset speed threshold can be obtained through experiments, for example, 50km / h.

[0093] Furthermore, if Figure 1 As shown, the vehicle further includes a first prompting device 80. The control method further includes:

[0094] When it is determined that the air in which the vehicle is located is at a pollution level and the current speed of the vehicle is higher than the preset speed threshold, controlling the first prompting device 80 to send a first prompting signal to remind the driver to slow down;

[0095] When the vehicle decelerates to a speed lower than or equal to a preset speed threshold, the opening and closing device 10 is controlled to close.

[0096] In this way, the driver can be reminded to reduce the speed as soon as possible, so as to control the opening and closing device 10 to close as soon as possible, which can reduce the time that the driver and passengers are exposed to polluted air and improve the driving experience of the driver and passengers.

[0097] In some embodiments, the first prompt device 80 includes an on / off device to close an action indicator light and / or a voice module. The controlling the first prompt device 80 to send a first prompt signal includes:

[0098] Control the closing action indicator light of the opening and closing device to flash; and / or,

[0099] The voice module is controlled to broadcast a first voice message for reminding the driver to slow down.

[0100] Furthermore, the control method further includes:

[0101] After controlling the opening and closing device 10 to close, controlling the first prompting device 80 to stop sending the first prompting signal.

[0102] In some embodiments, the vehicle further includes an air purification device 71 .

[0103] After controlling the opening and closing device 10 to close, the control method further includes:

[0104] The air purification device 71 is controlled to start to purify the air in the vehicle.

[0105] For example, Figure 1 As shown, the air purification device 71 is electrically connected to the central control unit 70 , and its working state is controlled by the central control unit 70 .

[0106] In this way, by controlling the air purification device 71 to start the purification function, the PM2.5 particulate matter content in the vehicle can be reduced, reducing the harm of haze to drivers and passengers.

[0107] In some embodiments, the control method further includes:

[0108] In the process of purifying the air by the air purification device 71, obtaining the air quality information in the vehicle;

[0109] According to the air quality information in the vehicle, determining whether the air in the vehicle is at a good level;

[0110] When it is determined that the air in the vehicle is at a good level, the air purification device 71 is controlled to be closed.

[0111] In this way, when the quality of the air in the vehicle reaches an excellent level, the air purification device 71 is controlled to be turned off, which can save electric energy.

[0112] In some embodiments, the control method further includes:

[0113] When it is determined that the air in the vehicle is at a good level and after the air purification device 71 is controlled to be turned off, the voice module is controlled to output a third voice message.

[0114] The third voice message is used to inform the driver and passengers that the air purification task of the air purification device 71 has been completed.

[0115] Further, the determining whether the quality of the air in the vehicle is at a good level includes:

[0116] Calculate the average value of PM2.5 values ​​represented by data collected by the PM2.5 sensor in the vehicle at preset time intervals;

[0117] Determine whether the average value of the PM2.5 value calculated each time is greater than or equal to the preset concentration threshold;

[0118] When it is determined that the average value of the PM2.5 value calculated currently is less than the preset concentration threshold, it is determined that the air in the vehicle is at a good level.

[0119] In some embodiments, the vehicle further comprises a second prompting device. The control method further comprises:

[0120] According to the PM2.5 values ​​represented by the data collected by the multiple PM2.5 sensors 20, judging whether each of the PM2.5 sensors 20 is normal;

[0121] When there is at least one faulty sensor among the multiple PM2.5 sensors 20, the PM2.5 value represented by the data collected by the faulty sensor is discarded, and the second prompt device is controlled to send a second prompt signal to remind the driver to replace the faulty sensor in time.

[0122] In some embodiments, the second prompting device is the central control unit 70 .

[0123] In this way, when some of the multiple PM2.5 sensors 20 fail, the opening and closing device 10 can still be controlled to open or close by relying on the PM2.5 value represented by the data collected by other normal PM2.5 sensors, thereby increasing the reliability of the system.

[0124] Furthermore, judging whether each of the PM2.5 sensors 20 is normal according to the PM2.5 value represented by the data collected by the multiple PM2.5 sensors 20 includes:

[0125] When the duration of unresponsiveness of the PM2.5 sensor 20 is greater than the third preset duration, or the difference between the PM2.5 value represented by the data collected by the PM2.5 sensor 20 and the average value of the PM2.5 value represented by the data collected by other PM2.5 sensors 20 is greater than the preset error threshold, the PM2.5 sensor 20 is determined to be a faulty sensor.

[0126] The preset error threshold can be determined according to the detection accuracy of the multiple PM2.5 sensors 20. When a PM2.5 sensor 20 does not respond for a long time or the difference between the PM2.5 value represented by the collected data and the average value of the PM2.5 value represented by the data collected by other PM2.5 sensors 20 is too large, it can be preliminarily determined that the PM2.5 sensor 20 is faulty.

[0127] In some embodiments, the control method further includes:

[0128] When receiving a first voice control instruction for triggering the opening of the opening and closing device 10, controlling the opening and closing device 10 to open; and / or,

[0129] When a second voice control instruction for triggering the closing of the opening and closing device 10 is received, the opening and closing device 10 is controlled to close.

[0130] The control system 100 of the vehicle has a voice control function, and the driver and passenger can output a voice wake-up command to the central control unit 70 to wake up the voice control function of the control system 100 of the vehicle and execute the relevant voice control command. For example, the second voice control command may include keywords such as "close the opening and closing device" and "haze is coming". In this way, the driver and passenger can control the opening and closing device 10 to open and / or close without manual operation, which is more intelligent.

[0131] In some embodiments, Figure 1 As shown, the vehicle further includes a motor 40 and a motor speed sensor 60, wherein the motor 40 is connected to the opening and closing device 10, and the motor 40 drives the opening and closing device 10 to close when rotating in a first direction, and drives the opening and closing device 10 to open when rotating in a second direction, wherein the second direction is opposite to the first direction. The motor speed sensor 60 is connected to the motor 40, and the motor speed sensor 60 is used to detect the speed of the motor 40. Exemplarily, the motor speed sensor 60 includes a Hall sensor.

[0132] The controlling the opening and closing device to close comprises:

[0133] The motor 40 is controlled to rotate in a first direction to drive the opening and closing device 10 to close.

[0134] The control method further comprises:

[0135] In the process of controlling the motor 40 to rotate in the first direction, obtaining the rotation speed of the motor 40;

[0136] According to the rotation speed of the motor 40, it is determined whether the opening and closing device 10 encounters an obstacle during the closing process;

[0137] When it is determined that the opening and closing device 10 encounters an obstacle during the closing process, the motor 40 is controlled to stop rotating or rotate by a preset angle in the second direction.

[0138] In this way, it is possible to prevent the body parts of the driver or other objects from being caught by the opening and closing device 10 , thereby improving safety.

[0139] It should be noted that when the opening and closing device 10 encounters an obstacle during the closing process, the speed of the motor 40 will quickly drop from the normal speed to 0, that is, the absolute value of the acceleration of the motor 40 will suddenly become very large.
