Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to an in-vehicle safety control method, electronic equipment, vehicle, and storage medium. Background Technology

[0002] In current vehicles, during high-temperature summer conditions, the air conditioning defaults to internal recirculation mode for energy conservation. In winter, while external recirculation is used to improve windshield defogging, some vehicles still maintain internal recirculation in low temperatures to further improve fuel efficiency, addressing windshield fogging through other means. Therefore, due to the relatively good sealing and internal recirculation mode, there is virtually no air exchange between the vehicle and the outside environment. When there are many people in the car, the concentration of carbon dioxide (CO2) inside gradually increases with driving time. High CO2 concentrations can cause discomfort and even affect driving safety. Furthermore, there is a risk of children or pets being left inside the vehicle. As oxygen levels decrease with consumption, and the interior temperature rises under summer heat, this can pose a significant safety risk.

[0003] Currently, there are solutions for detecting children and pets inside vehicles; however, existing solutions have many blind spots and are complex. For example, the published patent CN217145909U provides an in-vehicle life monitoring system and a car. This solution uses a combination of multi-functional sensors and cameras to monitor the presence of children or pets inside the vehicle. The multi-functional sensors are placed in the rear seats, and the camera is located in the driver's headrest. The camera and sensors have many blind spots; for example, children or pets in the front seats may not be detected. Furthermore, the camera and multi-functional sensors increase the complexity of the system hardware and the difficulty of deployment. Summary of the Invention

[0026] When the ambient temperature is greater than or equal to the preset temperature and the solar radiation intensity exceeds the preset solar radiation intensity, the vehicle's air conditioning system is dynamically controlled to operate in external circulation mode. The dynamic control includes: when the difference exceeds a third preset threshold, controlling the air conditioning system to operate in external circulation mode; and when the difference does not exceed the third preset threshold, controlling the air conditioning system to operate in internal circulation mode or to stop operating.

[0038] The invention employing the above technical solution has the following advantages:

[0039] In the technical solution provided in this application, data such as the vehicle's in-vehicle carbon dioxide concentration, remaining battery power, door open / closed status, and vehicle speed are collected to form a dataset. Based on this dataset, the external circulation damper and / or the window opening / closing status are controlled. When the in-vehicle carbon dioxide concentration exceeds a first preset threshold, the remaining battery power is less than a preset threshold, the doors are closed, and the vehicle speed is 0, the external circulation damper is open, and / or the window is at a specified opening degree greater than 0. Thus, by comprehensively controlling the in-vehicle ventilation through the in-vehicle carbon dioxide concentration, remaining battery power, and door open / closed status, it is beneficial to improve the safety of life inside the vehicle and avoid the failure to detect life inside the vehicle due to blind spots in harsh environments, thereby threatening the safety of life inside the vehicle. Furthermore, only a carbon dioxide concentration sensor needs to be deployed inside the vehicle, eliminating the need for cameras, oxygen concentration sensors, weight sensors, etc., which helps reduce the complexity of the system.

[0045] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In the description of this application, terms such as "first" and "second" are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] Please refer to Figure 1 This application provides an electronic device that may include a processing module and a storage module. The storage module stores a computer program, which, when executed by the processing module, enables the electronic device to perform corresponding steps in the following in-vehicle safety control method.

[0047] In this embodiment, the processing module and the storage module can be integrated into one unit, such as a smart cockpit controller, or they can be separate modules.

[0048] Electronic devices may also include in-vehicle CO2 (CO2 refers to the chemical formula of carbon dioxide) concentration sensors, out-of-vehicle CO2 concentration sensors, out-of-vehicle temperature sensors, solar radiation intensity sensors, and rainfall sensors, which can respectively collect data on in-vehicle carbon dioxide concentration, out-of-vehicle carbon dioxide concentration, ambient temperature, solar radiation intensity, and rainfall.

[0049] In addition, electronic devices can also obtain information such as the vehicle's remaining battery power, vehicle speed, door open / closed status, window opening degree, and external air circulation damper open / closed status. Among these, the methods for obtaining information such as remaining battery power, vehicle speed, door open / closed status, window opening degree, and external air circulation damper open / closed status are conventional and will not be elaborated here.

[0050] This application also provides a vehicle, which may include a vehicle body and the aforementioned electronic equipment. That is, the electronic equipment can be deployed on the vehicle as a hardware system of the vehicle.

[0051] Understandable, Figure 1 The electronic device structure shown is only a schematic diagram; the electronic device may also include more advanced components. Figure 1 Show more or fewer components. Figure 1 The components shown can be implemented using hardware, software, or a combination thereof.

[0052] Please refer to Figure 2 This application also provides an in-vehicle safety control method. The in-vehicle safety control method may include the following steps:

[0053] Step 110: Obtain the dataset corresponding to the vehicle, which includes the vehicle's in-vehicle carbon dioxide concentration, the vehicle's remaining battery power, the door open / close status, and the vehicle speed.

[0054] Step 120: Based on the dataset, control the opening and closing state of the vehicle's external circulation damper and / or windows, wherein the external circulation damper is in the open state when the carbon dioxide concentration inside the vehicle exceeds a first preset threshold, the remaining battery power is less than a preset battery power, the doors are in the closed state, and the vehicle speed is 0, and / or the windows are in a specified opening degree, the specified opening degree being greater than 0.

[0055] The steps of the in-vehicle safety control method will be explained in detail below:

[0056] In step 110, the various types of data in the dataset are acquired in a conventional manner. For example, the electronic device can collect the carbon dioxide concentration inside the vehicle through an in-vehicle CO2 concentration sensor. In addition, the electronic device can communicate with the vehicle's dashboard to obtain data such as the vehicle's remaining battery power, door open / closed status, and vehicle speed collected by the dashboard.

[0057] It should be noted that the dataset can include not only in-vehicle carbon dioxide concentration, remaining battery power, door open / closed status, and vehicle speed, but also other data. For example, the dataset may also include, but is not limited to, outside carbon dioxide concentration, ambient temperature, rainfall data, and solar radiation intensity.

[0058] In step 120, the electronic device can flexibly detect whether there is life inside the vehicle and whether to ventilate the closed cabin based on different types of data in the dataset and different values ​​of each type of data, so as to improve the air / environment quality inside the vehicle and ensure the comfort and safety of life inside the vehicle.

[0059] As an optional implementation, the dataset may include in-vehicle carbon dioxide concentration, remaining battery power, door open / closed status, vehicle speed, ambient temperature, and solar radiation intensity. In step 120, controlling the vehicle's external air circulation damper and / or window open / closed status based on the dataset may include:

[0060] When the carbon dioxide concentration inside the vehicle exceeds the first preset threshold, the remaining power is greater than or equal to the preset power, the vehicle door is closed, and the vehicle speed is 0, determine whether the ambient temperature is greater than or equal to the preset temperature and whether the solar radiation intensity exceeds the preset solar radiation intensity.

[0061] When the ambient temperature is greater than or equal to the preset temperature and the solar radiation intensity exceeds the preset solar radiation intensity, the vehicle's air conditioning system is dynamically controlled to operate in external circulation mode. The dynamic control includes: when the carbon dioxide concentration inside the vehicle exceeds the first preset threshold, controlling the air conditioning system to operate in external circulation mode so that the external circulation damper is in the open state; when the carbon dioxide concentration inside the vehicle does not exceed the first preset threshold, controlling the air conditioning system to operate in internal circulation mode or stop operating.

[0062] In this embodiment, various preset or specified values ​​can be flexibly set according to actual conditions. The impact of carbon dioxide concentration on air quality can be seen in Table 1 below.

[0063] Table 1:

[0064]

[0065] As an example, when the electronic device determines that the car door is locked, the vehicle speed is 0 km / h, the battery SOC is ≥10%, and the carbon dioxide concentration inside the vehicle exceeds 800 ppm, the processing module (such as the controller) judges the ambient temperature T and solar radiation intensity W based on the above conditions, and sends an alarm signal to the mobile phone. When the ambient temperature T ≥30℃ and the solar radiation intensity W >100 watts per square meter (unit: W / m²), the alarm signal is triggered. 2 When the air conditioning system compressor is turned on, the processing module controls the air conditioning system to start, and the air conditioning system is turned on to maintain the interior temperature at 26°C. Based on the real-time collected interior carbon dioxide concentration, the external circulation is dynamically adjusted until the carbon dioxide concentration is below 800 ppm.

[0066] The dynamic adjustment of the vehicle's external air circulation means that if the carbon dioxide concentration inside the vehicle exceeds 800 ppm, the air conditioning system will be switched to external air circulation mode, i.e., the external air circulation damper will be open; if the carbon dioxide concentration inside the vehicle does not exceed 800 ppm, the air conditioning system will operate in internal air circulation mode or stop operating. In this way, by combining temperature and solar radiation intensity to regulate ventilation and temperature inside the vehicle, excessively high temperatures and carbon dioxide concentrations can be avoided. In addition, it avoids high energy consumption for cooling due to prolonged external air circulation in cooling mode when the carbon dioxide concentration is low.

[0067] As an optional implementation, the method may further include:

[0068] During the operation of the vehicle's air conditioning system in external circulation mode under dynamic control, if the remaining power is less than the preset power and the carbon dioxide concentration inside the vehicle exceeds the first preset threshold for a specified duration, the air conditioning system is controlled to stop operating, and the external circulation damper is kept open.

[0069] As an example, during the operation of the vehicle's air conditioning system in external recirculation mode under dynamic control, if the carbon dioxide concentration inside the vehicle consistently exceeds 800 ppm for more than 10 seconds and the remaining battery power is below 10%, the air conditioning system will be turned off, and the external recirculation damper will be opened to connect the air in the cabin with the ambient air, thereby diluting the carbon dioxide concentration inside the vehicle. Understandably, if the remaining battery power is low (e.g., less than 10%), continuing to operate the air conditioning system could easily deplete the remaining battery power quickly, affecting the normal use of the vehicle. Therefore, turning off the air conditioning system when the battery power is low is beneficial for the subsequent normal use of the vehicle.

[0070] As an optional implementation, the dataset also includes ambient temperature and rainfall data. In step 120, based on the dataset, controlling the opening and closing state of the vehicle's external air circulation damper and / or windows includes:

[0071] When the carbon dioxide concentration inside the vehicle exceeds the first preset threshold, the remaining power is greater than or equal to the preset power, the vehicle door is closed, and the vehicle speed is 0, it is determined whether the ambient temperature is less than a preset temperature and whether the rainfall data is less than or equal to a preset rainfall.

[0072] When the ambient temperature is lower than the preset temperature and the rainfall data is lower than the preset rainfall, the vehicle's air conditioning system is controlled to operate in external circulation mode, so that the external circulation damper is in the open state, and the windows are controlled to be in a specified opening degree. When the carbon dioxide concentration inside the vehicle is lower than the first preset threshold, the vehicle's air conditioning system is controlled to be turned off, and the windows are controlled to be closed.

[0073] As an example, if the detected carbon dioxide concentration inside the vehicle exceeds 800 ppm, the remaining battery power is ≥10%, the doors are closed, the vehicle speed is 0 km / h, and the ambient temperature T < 30℃ and the rainfall data is 0 (indicating no rain), the controller will control the air conditioning system to open the external circulation damper and lower the front windows by 50 mm (or 10% of the total opening) until the detected carbon dioxide concentration inside the vehicle is below 800 ppm, at which point the alarm signal will no longer be issued. At this point, the controller will either adjust the air conditioning system's internal and external circulation dampers to their initial positions or turn off the air conditioning system and close the windows. The initial positions can be flexibly set according to actual conditions. The window opening can be understood as follows: when a single window is completely closed, the window opening is 0%; when a single window is completely open, the window opening is 100%.

[0074] As an optional implementation, the dataset may also include the external carbon dioxide concentration. In step 120, controlling the opening and closing state of the vehicle's external air circulation damper and / or windows based on the dataset may include:

[0075] When the difference between the carbon dioxide concentration inside the vehicle and the carbon dioxide concentration outside the vehicle exceeds a second preset threshold, the vehicle door is closed, and the vehicle speed is greater than 0, the vehicle's air conditioning system is controlled to alternate between external circulation mode and internal circulation mode. The single run duration of the external circulation mode is a first preset duration, and the single run duration of the internal circulation mode is a second preset duration. When the difference is less than or equal to a third preset threshold, the air conditioning system is controlled to run in the internal circulation mode or stop running. The third preset threshold is less than the second preset threshold.

[0076] When the difference between the carbon dioxide concentration inside the vehicle and the carbon dioxide concentration outside the vehicle exceeds the second preset threshold, the vehicle door is closed, and the vehicle speed is 0, the external circulation damper is controlled to be open and the vehicle window is controlled to be at a specified opening degree. When the difference is less than or equal to the third preset threshold, the external circulation damper is controlled to be closed and the vehicle window is controlled to be closed.

[0077] As an example, when the carbon dioxide concentration inside the vehicle is greater than the carbon dioxide concentration outside the vehicle by more than 200 ppm, the controller continuously issues an alarm signal. At this time, the electronic equipment assumes that there are passengers or other living beings (such as pets) in the passenger compartment. At the same time, it judges the vehicle speed. When the vehicle speed is greater than 0 km / h, it is not necessary to check the remaining battery power. The controller controls the air conditioning system to adjust the internal and external circulation dampers to external circulation, so that the external circulation damper opens. After 5 seconds, it is adjusted to internal circulation, and then after another 5 seconds, it is adjusted back to external circulation. This cycle continues until the difference between the carbon dioxide concentration inside and outside the vehicle is ≤50 ppm. At this time, the controller controls the air conditioning system to adjust the internal and external circulation dampers to internal circulation.

[0078] When the carbon dioxide concentration inside the vehicle is greater than the carbon dioxide concentration outside the vehicle by more than 200 ppm, if the vehicle speed is 0 km / h, the controller will adjust the air conditioning system's internal and external circulation dampers to external circulation, lower the front windows by 50 mm, and send an alarm signal to the driver's user terminal (such as a smartphone) via the vehicle's TBOX. The controller will continue to adjust the air conditioning system's internal and external circulation dampers to their initial positions and close the windows when the difference between the carbon dioxide concentration inside and outside the vehicle is ≤50 ppm.

[0079] It should be noted that before using the difference between the carbon dioxide concentration inside and outside the vehicle to determine in-vehicle safety, triggering conditions can be set. For example, the judgment of the difference between the carbon dioxide concentration inside and outside the vehicle can only be triggered when the carbon dioxide concentration inside the vehicle exceeds 800 ppm.

[0080] Please refer to Figure 3 The controller (processing module) can comprehensively analyze the carbon dioxide concentration outside the vehicle, the carbon dioxide concentration inside the vehicle, the vehicle speed signal, the outside temperature signal (ambient temperature), the locking signal (the door closing signal), the solar radiation intensity, the battery charge, and the rainfall signal (rainfall data), and flexibly control the air conditioning system and the opening of the windows based on the analysis results.

[0081] For example, as an optional implementation, the dataset may include the in-vehicle carbon dioxide concentration, the vehicle's remaining battery power, the door open / closed status, vehicle speed, outside carbon dioxide concentration, ambient temperature, and solar radiation intensity. In step 120, controlling the vehicle's external air circulation damper and / or the window's open / closed status based on the dataset may include:

[0082] When the difference between the carbon dioxide concentration inside the vehicle and the carbon dioxide concentration outside the vehicle exceeds a second preset threshold, the remaining power is greater than or equal to the preset power, the vehicle door is closed, and the vehicle speed is 0, it is determined whether the ambient temperature is greater than or equal to a preset temperature and whether the solar radiation intensity exceeds a preset solar radiation intensity.

[0083] When the ambient temperature is greater than or equal to the preset temperature and the solar radiation intensity exceeds the preset solar radiation intensity, the vehicle's air conditioning system is dynamically controlled to operate in external circulation mode. The dynamic control includes: when the difference exceeds a third preset threshold, controlling the air conditioning system to operate in external circulation mode; and when the difference does not exceed the third preset threshold, controlling the air conditioning system to operate in internal circulation mode or to stop operating. The third preset threshold is less than the second preset threshold.

[0084] As an example, when the electronic device determines that the car doors are locked, the vehicle speed is 0 km / h, the battery SOC is ≥10%, and the carbon dioxide concentration inside the vehicle is more than 200 ppm higher than the carbon dioxide concentration outside the vehicle, the controller judges the ambient temperature T and solar radiation intensity W based on the above conditions, and simultaneously sends an alarm signal to the mobile phone. If the ambient temperature T ≥30℃ and the solar radiation intensity W >100 watts per square meter (unit: W / m²), then the alarm signal is triggered. 2 When the air conditioner is in use, the controller starts the compressor of the air conditioning system and activates the cooling mode of the air conditioning system to maintain the interior temperature at 26°C. Based on the real-time difference between the CO2 concentration inside and outside the passenger compartment, the controller dynamically adjusts the external air circulation in the vehicle until the difference between the CO2 concentration inside and outside the vehicle is ≤50ppm, at which point the air conditioning system is turned off.

[0085] The dynamic adjustment of the vehicle's external air circulation means that if the carbon dioxide concentration inside the vehicle is more than 200 ppm higher than the carbon dioxide concentration outside the vehicle, the air conditioning system will be controlled to operate in external air circulation mode, that is, the external air circulation damper will be open; if the difference between the carbon dioxide concentration inside the vehicle and the carbon dioxide concentration outside the vehicle is less than or equal to 200 ppm, the air conditioning system will be controlled to operate in internal air circulation mode or stop operating.

[0086] As an optional implementation, the method further includes:

[0087] During the operation of the vehicle's air conditioning system in external circulation mode under dynamic control, if the remaining battery power is less than the preset battery power and the difference exceeds the third preset threshold for a specified duration, the air conditioning system is controlled to stop operating, and the external circulation damper is controlled to be in the open state.

[0088] As an example, during the operation of the vehicle's air conditioning system in external circulation mode, if the carbon dioxide concentration inside the vehicle is continuously greater than 200 ppm higher than the carbon dioxide concentration outside the vehicle for more than 10 seconds, the controller will continuously issue an alarm signal until the remaining battery power is lower than 10%, at which point the air conditioning system will be turned off and the external circulation damper will remain open.

[0089] As an optional implementation, the dataset may include in-vehicle carbon dioxide concentration, remaining vehicle battery power, door open / closed status, vehicle speed, outside carbon dioxide concentration, ambient temperature, and rainfall data. In step 120, based on the dataset, controlling the vehicle's external air circulation damper and / or the window's open / closed status includes:

[0090] When the difference between the carbon dioxide concentration inside the vehicle and the carbon dioxide concentration outside the vehicle exceeds a second preset threshold, the remaining battery power is greater than or equal to the preset battery power, the vehicle door is closed, and the vehicle speed is 0, it is determined whether the ambient temperature is less than a preset temperature and whether the rainfall data is less than or equal to a preset rainfall.

[0091] When the ambient temperature is lower than the preset temperature and the rainfall data is lower than the preset rainfall, the vehicle's air conditioning system is controlled to operate in external circulation mode, so that the external circulation damper is in the open state, and the windows are controlled to be in a specified opening degree. When the carbon dioxide concentration inside the vehicle is lower than the first preset threshold, the vehicle's air conditioning system is controlled to be turned off, and the windows are controlled to be closed.

[0092] As an example, when the electronic device determines that the car door is locked, the vehicle speed is 0 km / h, the battery SOC is ≥10%, the carbon dioxide concentration inside the vehicle is greater than the carbon dioxide concentration outside the vehicle by more than 200 ppm, and the ambient temperature T <30℃ and the rainfall data is 0 (indicating no rain), the controller controls the air conditioning system's internal and external circulation dampers to adjust to external circulation, so that the external circulation damper is opened. In addition, the front windows are lowered by 50 mm until the CO2 concentration inside the vehicle minus the CO2 concentration outside the vehicle is ≤50 ppm. At this time, the controller controls the air conditioning system's internal and external circulation dampers to adjust to the initial position and closes the windows.

[0093] Please refer to Figure 4In other implementations, the electronic device may not rely on solar radiation intensity, rainfall data, or external carbon dioxide concentration; it can control in-vehicle ventilation safety solely based on the in-vehicle carbon dioxide concentration. For example, if the in-vehicle carbon dioxide concentration exceeds 800 ppm and the vehicle speed is >0 km / h, the controller adjusts the air conditioning system's internal / external circulation damper to external circulation, then to internal circulation after 5 seconds, and back to external circulation after another 5 seconds, repeating this cycle until the CO2 sensor stops issuing alarm signals (using the example of the CO2 sensor alarming when the concentration exceeds 800 ppm and not alarming when it does not exceed 800 ppm). At this point, the controller adjusts the air conditioning system's internal / external circulation damper to internal circulation. When the vehicle speed is 0 km / h, the controller adjusts the air conditioning system's internal / external circulation damper to external circulation, lowers the front windows by 50 mm, and sends an alarm signal to the mobile phone via the vehicle's TBOX. When the CO2 sensor stops issuing alarm signals, the controller adjusts the air conditioning system's internal / external circulation damper to its initial position and closes the windows.

[0094] As an optional implementation, the method may further include:

[0095] When the carbon dioxide concentration inside the vehicle exceeds the first preset threshold, or when the difference between the carbon dioxide concentration inside the vehicle and the carbon dioxide concentration outside the vehicle in the dataset exceeds the second preset threshold, an alarm is issued to the user terminal.

[0096] The user terminal is typically the driver's smartphone, allowing the driver to receive timely alarm notifications. The alarm notification may include information indicating the presence of a child, pet, or other living being in the vehicle. Of course, in other implementations, the user terminal can also be a personal computer, tablet, or other similar device.

[0097] Based on the above design, the electronic device detects the CO2 concentration inside the vehicle to determine if there are any living beings such as children or pets inside. When a child or animal is detected, it automatically adjusts the air conditioning's internal and external air circulation settings or opens the windows. It can also send a message to the owner's registered mobile phone via the vehicle's communication device, informing them of the presence of a child or animal. Furthermore, when a child or animal is detected, the system can automatically activate the air conditioning system, taking into account remaining battery power, sunlight exposure, and outside temperature, to prevent children from fainting due to excessively high interior temperatures or carbon dioxide concentrations.
