Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly provides a control method for a vehicle and a vehicle. Background Art

[0002] With the improvement of people's living standards, vehicles have gradually become an essential means of transportation in people's daily lives.

[0003] When people rest in the vehicle and start the engine for heating, the exhaust gas generated by the vehicle contains a large amount of toxic gases such as carbon monoxide. Or, when people drive the vehicle and encounter traffic jams, the surrounding vehicles will also generate a large amount of toxic gases such as carbon monoxide. Carbon monoxide will enter the vehicle through the gaps of the vehicle and the air conditioning system. When the concentration of carbon monoxide in the vehicle is too high, the passengers in the vehicle will be poisoned, and even pose a hazard to the life safety of the passengers.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problems, that is, to solve the problem that the concentration of carbon monoxide in the existing vehicle exceeds the standard, resulting in poisoning of the passengers.

[0006] In a first aspect, the present invention provides a control method for a vehicle. The vehicle includes an air conditioning system and a purification device installed on the air conditioning system. The purification device can purify carbon monoxide. The control method includes: obtaining the concentration of carbon monoxide in the vehicle, denoted as the first concentration; selectively starting the air conditioning system and the purification device according to the first concentration, and selectively making the vehicle emit an alarm that the concentration of carbon monoxide exceeds the standard.

[0007] In a preferred technical solution of the above control method for a vehicle, the step of "selectively starting the air conditioning system and the purification device according to the first concentration, and selectively making the vehicle emit an alarm that the concentration of carbon monoxide exceeds the standard" specifically includes: comparing the first concentration with a first preset concentration; selectively starting the air conditioning system and the purification device according to the comparison result, and selectively making the vehicle emit an alarm that the concentration of carbon monoxide exceeds the standard.

[0008] In the preferred technical solution of the above vehicle control method, the step of "selectively starting the air conditioning system and the purification device according to the comparison result, and selectively causing the vehicle to issue an alarm that the concentration of carbon monoxide exceeds the standard" specifically includes: if the first concentration is greater than the first preset concentration, start the air conditioning system and the purification device, and cause the vehicle to issue an alarm that the concentration of carbon monoxide exceeds the standard; and / or if the first concentration is not greater than the first preset concentration, do not start the air conditioning system and the purification device, and do not cause the vehicle to issue an alarm that the concentration of carbon monoxide exceeds the standard.

[0009] In the preferred technical solution of the above vehicle control method, the control method further includes: when the running time of the purification device reaches the first preset time, obtain the concentration of carbon monoxide in the vehicle again, denoted as the second concentration; according to the second concentration, selectively open the vehicle window, and selectively increase the wind speed of the air conditioning system.

[0010] In the preferred technical solution of the above vehicle control method, the step of "selectively opening the vehicle window and selectively increasing the wind speed of the air conditioning system according to the second concentration" specifically includes: comparing the second concentration with the first preset concentration and the second preset concentration respectively, where the second preset concentration is greater than the first preset concentration; according to the comparison result, selectively open the vehicle window and selectively increase the wind speed of the air conditioning system.

[0011] In the preferred technical solution of the above vehicle control method, the step of "selectively opening the vehicle window and selectively increasing the wind speed of the air conditioning system according to the comparison result" specifically includes: if the second concentration is greater than the first preset concentration and less than the second preset concentration, increase the wind speed of the air conditioning system.

[0012] In the preferred technical solution of the above vehicle control method, the step of "selectively opening the vehicle window and selectively increasing the wind speed of the air conditioning system according to the comparison result" specifically includes: if the second concentration is greater than or equal to the second preset concentration, increase the wind speed of the air conditioning system and open the vehicle window

[0013] In the preferred technical solution of the above vehicle control method, in the case where the first concentration is greater than the first preset concentration, the control method further includes: detecting whether there are passengers in the vehicle; according to the detection result, selectively causing the vehicle to send information that the concentration of carbon monoxide exceeds the standard to the reserved contacts of the vehicle.

[0014] In the preferred technical solution of the above vehicle control method, the step of "selectively sending information on the excessive concentration of carbon monoxide to the reserved contacts of the vehicle according to the detection result" specifically includes: if the detection result is that there are no passengers in the vehicle, the vehicle sends information on the excessive concentration of carbon monoxide to the reserved contacts of the vehicle.

[0015] In a second aspect, the present invention also provides a vehicle. The vehicle of the present invention further includes a controller configured to be able to execute the above control method.

[0016] Those skilled in the art can understand that in the vehicle of the present invention, by obtaining the concentration of carbon monoxide in the vehicle, i.e., the first concentration, and comparing the first concentration with the first preset concentration, when the first concentration is greater than the first preset concentration, the concentration of carbon monoxide in the vehicle has exceeded the concentration range that the human body can withstand, which will make the passengers feel uncomfortable. At this time, the vehicle starts the air conditioning system and the purification device to purify carbon monoxide, so as to reduce the concentration of carbon monoxide, and at the same time issues an alarm on the excessive concentration of carbon monoxide to remind the passengers to open the window for ventilation.

[0017] Further, when the running time of the purification device of the vehicle of the present invention reaches the first preset time, the vehicle obtains the concentration of carbon monoxide in the vehicle again, i.e., the second concentration, and compares the second concentration with the first preset concentration and the second preset concentration respectively. When the second concentration is greater than the first preset concentration and less than the second preset concentration, it means that the change in the concentration of carbon monoxide in the vehicle is not significant. At this time, by increasing the wind speed of the air conditioning system, the purification efficiency of the purification device is improved. When the second concentration is greater than or equal to the second preset concentration, it means that the concentration of carbon monoxide in the vehicle is still increasing. At this time, by increasing the wind speed of the air conditioning system, while improving the purification efficiency of the purification device, the window is opened for ventilation, so as to reduce the concentration of carbon monoxide in the vehicle.

[0018] Still further, in the case where the first concentration is greater than the first preset concentration in the vehicle of the present invention, by detecting whether there are passengers in the vehicle, when it is detected that there are no passengers in the vehicle, it means that the owner may have forgotten to turn off the engine or other reasons resulting in an increase in the concentration of carbon monoxide in the vehicle. At this time, the vehicle will send information on the excessive concentration of carbon monoxide to the reserved contacts of the vehicle to remind the owner to turn off the engine and open the window for ventilation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, in which:

[0020] Figure 1 is a flowchart of the control method of the vehicle of the present invention;

[0021] Figure 2 is a flowchart of an embodiment of the control method of the vehicle of the present invention. Detailed implementation manners

[0022] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0001] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that in the description of the present invention, although the steps of the control method of the present invention are described in a specific order in this application, these orders are not restrictive. Without departing from the basic principle of the present invention, those skilled in the art can execute the steps in a different order.

[0023] It should be noted that in the description of the present invention, the terms "inner", "outer", "upper", "lower", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0024] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "arranged", "connected", "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0025] Based on the problem pointed out in the background art that the carbon monoxide concentration in the existing vehicle exceeds the standard and causes poisoning of the driver and passengers, the present invention provides a control method and a vehicle for a vehicle, aiming to obtain the concentration of carbon monoxide in the vehicle, that is, the first concentration, and compare the first concentration with the first preset concentration. When the first concentration is greater than the first preset concentration, the concentration of carbon monoxide in the vehicle has exceeded the concentration range that the human body can bear, which will make the driver and passengers feel uncomfortable. At this time, the vehicle starts the air conditioning system and the purification device to purify carbon monoxide, so as to reduce the concentration of carbon monoxide, and at the same time issues an alarm that the concentration of carbon monoxide exceeds the standard to remind the driver and passengers to open the window for ventilation.

[0026] Specifically, the present invention provides a vehicle, which includes an air conditioning system and a purification device installed on the air conditioning system, and the purification device can purify carbon monoxide.

[0027] Exemplarily, the vehicle of the present invention can be a fuel vehicle such as a motorhome, a truck or a sedan. When people rest in the vehicle, for example, when the driver rests in the vehicle waiting for someone, if the temperature inside the vehicle is too high or too low, the vehicle needs to be started and the air conditioning system needs to be turned on to adjust the temperature inside the vehicle. When the engine is in an idle state, a large amount of toxic gases such as carbon monoxide will be generated. Carbon monoxide and other gases will enter the vehicle through the gaps of the vehicle and the air conditioning system. Or, when the driver uses a diesel heater for heating in a motorhome, a large amount of toxic gases such as carbon monoxide will also be generated. When the concentration of carbon monoxide in the vehicle is too high, the passengers and the driver will have poisoning reactions such as chest tightness, shortness of breath, and difficulty breathing, and even threaten life safety. By installing a purification device inside the air outlet of the air conditioning system, the purification device can react with carbon monoxide, thereby adsorbing or catalyzing carbon monoxide into non-toxic carbon dioxide, thus reducing the concentration of carbon monoxide in the vehicle and ensuring the safety of the passengers and the driver.

[0028] It should be noted that the present invention does not limit the type of the purification device. For example, those skilled in the art can set the purification device as a device with activated carbon or molecular sieve to adsorb carbon monoxide in the air through the activated carbon or molecular sieve. Or, the purification device can also be set as a device with a catalyst, and the catalyst reacts with carbon monoxide at room temperature to oxidize carbon monoxide into non-toxic carbon dioxide, etc. Such adjustments and changes to the specific type of the purification device do not deviate from the principle and scope of the present invention and should all be limited within the protection scope of the present invention.

[0029] It should also be noted that the present invention does not limit the installation position and the installation quantity of the purification device. For example, those skilled in the art can install the purification device at the air outlet of the air conditioning system, or near the blower, etc. Multiple purification devices can also be installed. Such adjustments and changes to the specific installation position and the installation quantity of the purification device do not deviate from the principle and scope of the present invention and should all be limited within the protection scope of the present invention.

[0030] It should further be noted that the present invention can also install an air purification device such as a negative ion generator inside the air outlet of the air conditioning system. The automobile exhaust also contains a large amount of pollutants such as particulate matter. After the automobile exhaust enters the vehicle, the particulate matter will also cause discomfort to the passengers and the driver. While turning on the purification device, turn on the negative ion generator. The negative ion generator can purify the particulate matter, formaldehyde, benzene, etc. in the air, ensuring the cleanliness of the air inside the vehicle. Of course, the negative ion generator can also determine whether to be turned on according to the concentration of particulate matter in the vehicle. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should all be limited within the protection scope of the present invention.

[0031] It should be further noted that for devices such as the purification device and negative ion generator of the present invention, they need to be able to be turned on to purify the air even after the vehicle is turned off. Those skilled in the art can supply power to the purification device, negative ion generator and other devices through the vehicle's battery, and can also integrate a flexible solar film on the outer casing of the air conditioner and cooperate with a super capacitor to store electrical energy for power supply, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should all be defined within the protection scope of the present invention.

[0032] Certainly, the present invention preferably supplies power by integrating a flexible solar film on the outer casing of the air conditioner and cooperating with a super capacitor to store electrical energy, which can avoid excessive power consumption of the vehicle's battery and damage to the battery.

[0033] On the other hand, based on the vehicle introduced above, the present invention also provides a control method for a vehicle. As Figure 1 and Figure 2 shown, the control method of the present invention includes the following steps:

[0034] S100: Obtain the concentration of carbon monoxide in the vehicle, denoted as the first concentration p1.

[0035] Exemplarily, a gas concentration detection device is provided in the vehicle of the present invention, which can detect the concentration of carbon monoxide in the vehicle and transmit the concentration information of carbon monoxide to the vehicle controller by wire communication.

[0036] It should be noted that the present invention does not limit the type of the gas concentration detection device. For example, those skilled in the art can set the gas concentration detection device as a gas detector or a laser gas analyzer, etc. Such adjustments and changes to the specific type of the purification device do not deviate from the principle and scope of the present invention and should all be defined within the protection scope of the present invention.

[0037] It should also be noted that the present invention does not limit the installation position of the gas concentration detection device. For example, those skilled in the art can install the gas concentration detection device inside the air outlet of the air conditioning system, or install it in other spaces inside the vehicle, etc. Such adjustments and changes to the specific installation position of the purification device do not deviate from the principle and scope of the present invention and should all be defined within the protection scope of the present invention.

[0038] The present invention preferably installs the gas concentration detection device inside the air outlet of the air conditioning system. The installation position is concealed, does not occupy the vehicle interior space, and the detection data is relatively accurate.

[0039] S200: According to the first concentration p1, selectively start the air conditioning system and the purification device, and selectively make the vehicle issue an alarm that the concentration of carbon monoxide exceeds the standard.

[0040] Exemplarily, the controller of the vehicle according to the present invention may directly compare the first concentration p1 with a preset concentration, or may also divide the first concentration p1 by the preset concentration to obtain a ratio, and compare the ratio with a preset ratio range, etc.

[0041] Exemplarily, as Figure 2 shown, step S200 includes steps S210 to S230.

[0042] S210: Compare the first concentration p1 with the first preset concentration p01.

[0043] That is to say, a preset value of the carbon monoxide concentration, i.e., the first preset concentration p01, is set, and the detected first concentration p1 is directly compared with the first preset concentration p01.

[0044] S220: If the first concentration p1 is greater than the first preset concentration p01, start the air conditioning system and the purification device, and at the same time make the vehicle emit an alarm indicating that the concentration of carbon monoxide exceeds the standard.

[0045] Exemplarily, the first concentration p1 detected by the gas concentration detection device of the present invention is 60 ppm, and the first preset concentration p01 is 50 ppm. Since p01 > p1, it indicates that the concentration of carbon monoxide in the vehicle is too high and has affected the health of the passengers in the vehicle. In such an environment for a long time, the passengers will feel chest tightness, shortness of breath, and difficulty breathing. At this time, the controller of the vehicle controls the air conditioning system and the purification device to start to purify the carbon monoxide in the vehicle, thereby reducing the concentration of carbon monoxide. At the same time, the controller of the vehicle controls the vehicle to emit an audible and visual alarm to prompt the passengers that the carbon monoxide concentration in the vehicle exceeds the standard and remind the passengers to open the window for ventilation.

[0046] S230: If the first concentration p1 is not greater than the first preset concentration p01, do not start the air conditioning system and the purification device, and do not make the vehicle emit an alarm indicating that the concentration of carbon monoxide exceeds the standard.

[0047] Exemplarily, the first concentration p1 detected by the gas concentration detection device of the present invention is 20 ppm, and the first preset concentration p01 is 50 ppm. Since p01 < p1, it indicates that the concentration of carbon monoxide in the vehicle is relatively low and within the normal concentration range, which will not affect the health of the passengers in the vehicle. At this time, the vehicle does not start the air conditioning system and the purification device, and does not make the vehicle emit an alarm indicating that the concentration of carbon monoxide exceeds the standard.

[0048] It should be noted that the present invention does not limit the specific value of the first preset concentration p01. For example, those skilled in the art can also set the first preset concentration p01 to 30 ppm or 40 ppm, etc. Those skilled in the art can set it according to the actual situation. Such adjustments and changes to the specific value of the first preset concentration p01 do not deviate from the principle and scope of the present invention and should all be limited within the protection scope of the present invention.

[0049] It should be further noted that the first preset concentration p01 of the present invention can also be a dynamic value. For example, the value of the first preset concentration p01 is dynamically adjusted according to the situation of the people in the vehicle and the parking time. When there are people in the vehicle, the longer the parking time, the lower the value of the first preset concentration p01 is reduced to improve the sensitivity of the gas concentration detection device, which can avoid harm to the driver and passengers caused by detection data deviation. When there is no one in the vehicle, the longer the parking time, the higher the value of the first preset concentration p01 is increased to reduce the sensitivity of the gas concentration detection device, thereby avoiding false alarms and reducing the energy consumption of the vehicle.

[0050] For example, when there are passengers in the vehicle, the initial first preset concentration p01 is 50 ppm. Every hour, the value of the first preset concentration p01 is reduced by 10% to improve the sensitivity of the gas concentration detection device. For example, when the parking time is 30 minutes, the dynamic first preset concentration p01 is 50*(1 - 30 / 60*0.1) = 47.5 ppm. Or when the parking time is 120 minutes, the dynamic first preset concentration p01 is 50*(1 - 0.2) = 40 ppm.

[0051] Similarly, when there are no passengers in the vehicle, the initial first preset concentration p01 is 50 ppm. Every hour, the value of the first preset concentration p01 is increased by 10% to reduce the sensitivity of the gas concentration detection device. For example, when the parking time is 60 minutes, the dynamic first preset concentration p01 is 50*(1 + 0.1) = 55 ppm. Here, it will not be elaborated one by one. Those skilled in the art can set the dynamic change situation of the first preset concentration p01 according to the actual situation.

[0052] It should also be noted that the first preset concentration p01 of the present invention can also be corrected according to the temperature, humidity and oxygen O2 concentration in the vehicle. The lower the O2 concentration, the greater the harm of CO to the human body. In a high-temperature and high-humidity environment, the breathing rate of people can be accelerated, and CO is more likely to invade the human body, thus making it easier for the driver and passengers to be poisoned. A temperature and humidity sensor needs to be installed in the vehicle, and an O2 concentration detection device can be set separately, or the gas concentration detection device can be used to detect the concentrations of oxygen and carbon monoxide at the same time.

[0053] For example, if the first preset concentration p01 is 50 ppm, the current oxygen concentration in the vehicle is 15%, and the normal oxygen concentration is 21%, then the dynamic first preset concentration p01 is 50 * (18% / 21%) = 42 ppm. At this time, as long as the first concentration p1 detected by the gas concentration detection device is less than 42 ppm, the vehicle can control the purification device to turn on and simultaneously control the vehicle to emit an audible and visual alarm. The above correction formula is only an example, and those skilled in the art can set the correction formula according to the actual situation.

[0054] Further, the first preset concentration p01 is further corrected according to the temperature and humidity conditions in the vehicle. For example, the first preset concentration p01 corrected according to the O2 concentration is 42 ppm, the normal temperature in the vehicle is 26°, and the normal humidity in the vehicle is 50%. At this time, the actually detected temperature in the vehicle is 28° and the humidity is 55%, then the dynamic first preset concentration p01 is 35 * (26 / 28) * (50 / 55) = 35 ppm. At this time, as long as the first concentration p1 detected by the gas concentration detection device is less than 35 ppm, the vehicle can control the purification device to turn on and simultaneously control the vehicle to emit an audible and visual alarm. The above correction formula is only an example, and those skilled in the art can set the correction formula according to the actual situation.

[0055] Preferably, the control method of the vehicle of the present invention further includes the following steps:

[0056] S300: When the operation time of the purification device reaches the first preset time, the concentration of carbon monoxide in the vehicle is obtained again and denoted as the second concentration p2.

[0057] Exemplarily, 30 minutes after starting the purification device and simultaneously making the vehicle emit an alarm that the concentration of carbon monoxide exceeds the standard, the gas concentration detection device detects the concentration of carbon monoxide in the vehicle again and transmits the carbon monoxide concentration information to the vehicle controller by wire or wirelessly.

[0058] S400: According to the second concentration p2, selectively open the vehicle window and selectively increase the wind speed of the air conditioning system.

[0059] Exemplarily, the vehicle controller of the present invention can directly compare the second concentration p2 with the first preset concentration p01 to determine the size, and according to the comparison result, improve the response level of the vehicle. Or, a second preset concentration can also be set, where the second preset concentration is greater than the first preset concentration p01, and the second concentration p2 is compared with the first preset concentration p01 and the second preset concentration to determine the size, and according to the comparison result, improve the response level of the vehicle.

[0060] It should be noted that due to different environments in which the vehicle is located, different degrees of vehicle sealing, different purification efficiencies of the purification device, etc., after the purification device is turned on for a period of time, the concentration of carbon monoxide in the vehicle may increase or decrease. Therefore, it is necessary to detect the concentration of carbon monoxide in the vehicle multiple times, and different responses are made according to the change of the concentration of carbon monoxide in the vehicle. The response methods include but are not limited to: increasing the air volume of the air-conditioning system, increasing the voltage of the purification device to improve the purification efficiency, opening the window for ventilation, sound and light alarm, vehicle body vibration, or sending a text message to the reserved contact person or pushing an APP by the vehicle, etc. The above response methods can be used in various combinations, and can also be used in a step-by-step increasing manner, etc. Those skilled in the art can set according to the actual situation.

[0061] It should also be noted that the present invention does not limit the first preset time. For example, those skilled in the art can also set the first preset time to detect once every 20 minutes, or once every 40 minutes, or can also correct the time interval of the first preset time according to the change of the concentration of carbon monoxide in the vehicle. For example, if the detected second concentration p2 is greater than the first concentration p1, the time interval of the next detection can be reduced. For example, the next detection time is set to 15 minutes later, etc. Such flexible adjustment and change do not deviate from the principle and scope of the present invention, and should all be limited within the protection scope of the present invention.

[0062] Exemplarily, step S400 includes steps S410 to S430:

[0063] S410: Compare the second concentration p2 with the first preset concentration p01 and the second preset concentration p02 respectively, where the second preset concentration p02 is greater than the first preset concentration p01.

[0064] That is to say, compare the magnitudes of the second concentration p2 with the first preset concentration p01 and the second preset concentration p02 respectively to judge the change of the concentration of carbon monoxide in the vehicle after starting the purification device and simultaneously making the vehicle issue an alarm that the concentration of carbon monoxide exceeds the standard.

[0065] S420: If the second concentration p2 is greater than the first preset concentration p01 and the second concentration p2 is less than the second preset concentration p02, increase the wind speed of the air-conditioning system.

[0066] Exemplarily, the first preset concentration p01 of the present invention is 50 ppm, and the detected first concentration p1 is 60 ppm. After the first preset time, for example, 30 minutes, at this time, since the value of the first preset concentration p01 is a dynamic value and decreases as the parking time increases. According to the above calculation formula, the value of the first preset concentration p01 at this time decreases to p01 = 50 * (1 - 30 / 60 * 0.1) = 47.5 ppm. The second concentration p2 detected by the gas concentration detection device is 60 ppm, and the second preset concentration p02 is 100 ppm. Since p01 < p1 < p02, at this time, it indicates that after the purification device in the vehicle is turned on, the carbon monoxide concentration in the vehicle does not change much. It may be because the carbon monoxide concentration in the external environment is relatively high, or it is also possible that the purification efficiency of the purification device decreases after long-term use. At this time, the vehicle controls the air volume of the air conditioning system to increase the air volume, thereby improving the purification efficiency of the purification device to reduce the carbon monoxide concentration in the vehicle.

[0067] S430: If the second concentration p2 is greater than or equal to the second preset concentration p02, increase the air volume of the air conditioning system and at the same time open the vehicle window.

[0068] Exemplarily, the second concentration p2 detected by the gas concentration detection device is 110 ppm, and the second preset concentration p02 is 100 ppm. Since p1 > p02, at this time, it indicates that after the purification device in the vehicle is turned on, the carbon monoxide concentration in the vehicle not only does not decrease but increases. It may be that the purification device needs to be replaced, resulting in extremely low purification efficiency, so that the carbon monoxide entering the vehicle is more than that purified by the purification device. At this time, the vehicle controls the air volume of the air conditioning system to increase the air volume and at the same time open the vehicle window, thereby improving the purification efficiency of the purification device and reducing the carbon monoxide concentration in the vehicle by ventilation.

[0069] It should be noted that when the second concentration p2 is less than the first preset concentration p01, the purification device can be continuously turned on to continuously purify the air, or the purification device can be intermittently turned on to continuously purify the air, etc. Those skilled in the art can reasonably set according to the actual situation.

[0070] It should also be noted that the vehicle can issue an alarm for excessive carbon monoxide concentration, which can be continuous until the driver or passenger turns it off, or intermittent alarms, such as once every 10 minutes, lasting for 1 minute in sequence, etc. Those skilled in the art can also set the gear of the air conditioning system according to the actual situation, such as gradually increasing the gear of the air conditioning system according to the change magnitude of the second concentration p2, or increasing the gear of the air conditioning system in a jump, etc.

[0071] Preferably, when the first concentration is greater than the first preset concentration in the vehicle of the present invention, the control method further includes the following steps:

[0072] S500: Detect whether there are passengers in the vehicle;

[0073] Exemplarily, an infrared sensing device is installed in the vehicle of the present invention, which can detect whether there is anyone in the vehicle and transmit the detection information to the vehicle controller by wire communication.

[0074] S600: According to the detection result, selectively send information that the concentration of carbon monoxide exceeds the standard to the reserved contacts of the vehicle.

[0075] That is to say, according to whether there are people in the vehicle, it is judged whether to send information that the concentration of carbon monoxide exceeds the standard to the reserved contacts of the vehicle.

[0076] Exemplarily, step S600 includes steps S610 to S620:

[0077] S610: If the detection result is that there are no passengers in the vehicle, then send information that the concentration of carbon monoxide exceeds the standard to the reserved contacts of the vehicle.

[0078] Exemplarily, when the infrared sensing device detects that there is no one in the vehicle, it may be that the vehicle owner forgets to turn off the engine, or the vehicle owner starts the vehicle in advance through the app to warm up the car, etc., resulting in an increase in the concentration of carbon monoxide in the vehicle. At this time, the vehicle sends information that the concentration of carbon monoxide exceeds the standard to the reserved contacts to remind the vehicle owner.

[0079] S620: If passengers are detected in the vehicle, then do not send information that the concentration of carbon monoxide exceeds the standard to the reserved contacts of the vehicle.

[0080] Exemplarily, when the infrared sensing device detects that there are people in the vehicle, it means that the passengers in the vehicle are resting while the vehicle is idling, resulting in an increase in the concentration of carbon monoxide in the vehicle. At this time, the vehicle does not send information that the concentration of carbon monoxide exceeds the standard to the reserved contacts.

[0081] It should be noted that the vehicle of the present invention can send information that the concentration of carbon monoxide exceeds the standard to the reserved contacts by means of short messages or app push messages, etc.

[0082] Preferably, the vehicle of the present invention further includes a controller, and the controller can control the vehicle to complete the control method of any one of the above.

[0083] Those skilled in the art can understand that although some of the embodiments described herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means that it is within the scope of the present application and forms different embodiments. For example, in the claims of the present application, any one of the claimed embodiments can be used in any combination.

[0084] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings.
