Description

Technical Field

[0002] In the automotive industry, the selection and application of refrigerants for automotive air conditioning are undergoing a transformation towards environmentally friendly and sustainable options. Currently, the main new refrigerant alternatives in the industry include R290 (propane) and R744 (carbon dioxide). These refrigerants are relatively inexpensive and compatible with automobiles. However, the architecture of automotive air conditioning systems is not yet perfect, and new refrigerants may pose a risk of leakage. This could lead to safety hazards due to the inability to promptly expel accumulated gas, resulting in lower vehicle safety.

[0003] This demonstrates that the vehicle control methods in related technologies suffer from low safety. Summary of the Invention

[0030] To enable those skilled in the art to better understand the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present disclosure.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] In the automotive industry, the selection and use of refrigerants for automotive air conditioning are moving towards environmental protection and sustainability. Previous automotive air conditioning refrigerants, such as R134a, while meeting the cooling needs of automotive air conditioning to some extent, have a high global warming potential, which is detrimental to mitigating the rate of global warming. Therefore, finding environmentally friendly alternative refrigerants has become an urgent need in the automotive industry. Currently, the most frequently used new refrigerant alternatives in the automotive industry are R744 and R290. These two new refrigerants each have their own characteristics. Specifically, R290 has zero ozone depletion potential and low global warming potential, and its operating environment is similar to that of current automotive air conditioning systems, requiring fewer changes to system design and component requirements. It is harmless to the ozone layer and has a small impact on climate change, but it is flammable. R744 also has zero ozone depletion potential and low global warming potential, is harmless to the ozone layer and has a minimal impact on climate change, and is non-flammable, but its usage requirements for the entire system are significantly different, requiring more modifications to the vehicle.

[0033] Automobiles need to undergo certain system modifications to adapt to the various characteristics of new refrigerants. For example, the entry of new refrigerants into the passenger compartment can pose safety issues for the vehicle. However, current automobiles lack solutions to deal with such refrigerant leaks, and are unable to effectively address the potential leakage risks posed by these new refrigerants, resulting in lower vehicle safety.

[0034] This demonstrates that the vehicle control methods in related technologies suffer from low safety.

[0035] According to an embodiment of this disclosure, a method embodiment for controlling a vehicle is provided. It should be noted that the steps shown in the flowcharts in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0036] This method embodiment can be executed in an electronic device or similar computing device that includes memory and a processor. Taking operation on a computer terminal as an example, the computer terminal may include one or more processors (processors may include, but are not limited to, central processing units (CPUs), graphics processing units (GPUs), digital signal processing (DSP) chips, microcontroller units (MCUs), field-programmable gate arrays (FPGAs), neural network processors (NPUs), tensor processors (TPUs), artificial intelligence (AI) type processors, etc.) and memory for storing data. Optionally, the computer terminal may also include transmission devices, input / output devices, and display devices for communication functions. Those skilled in the art will understand that the above structural description is merely illustrative and does not limit the structure of the computer terminal. For example, the computer terminal may include more or fewer components than described above, or have a different configuration than described above.

[0037] The memory can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the vehicle control method in this embodiment. The processor executes various functional applications and data processing by running the computer program stored in the memory, thereby implementing the aforementioned vehicle control method. The memory may include high-speed random access memory and non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory may further include memory remotely located relative to the processor, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0038] The transmission device is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the mobile terminal's communication provider. In one example, the transmission device includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device may be a Radio Frequency (RF) module, used for wireless communication with the Internet.

[0039] Display devices can be, for example, touchscreen liquid crystal displays (LCDs) and touch displays (also referred to as "touchscreens" or "touch displays"). The LCD allows users to interact with the user interface of the mobile terminal. In some embodiments, the mobile terminal has a graphical user interface (GUI), which allows users to interact with the GUI through finger contact and / or gestures on a touch-sensitive surface. Optional human-computer interaction functions include: creating web pages, drawing, word processing, creating electronic documents, playing games, video conferencing, instant messaging, sending and receiving emails, call interfaces, playing digital video, playing digital music, and / or web browsing, etc. Executable instructions for performing the above human-computer interaction functions are configured / stored in one or more processor-executable computer program products or readable storage media.

[0040] Figure 1 This is a flowchart of a vehicle control method according to one embodiment of the present disclosure, such as... Figure 1 As shown, the method includes the following steps:

[0041] Step S11: Obtain the gas concentration value of the target gas in the target area inside the vehicle to obtain the current gas concentration value;

[0042] Step S12: When the current gas concentration value is greater than or equal to a preset concentration threshold, according to the vehicle's operating conditions, execute component control operations to reduce the gas concentration value of the target gas; wherein, the component control operations include at least one of the following: controlling the air duct guide component to switch to exhaust state to connect the target area with the outside of the vehicle, wherein, in exhaust state, the opening combination of the air inlet damper and the exhaust damper of the air duct guide component is dynamically adjusted according to the current vehicle speed; controlling the air volume regulating component to perform a reverse operation to exhaust the gas in the target area outside the vehicle.

[0043] For example, the aforementioned air duct guiding components and airflow regulating components can be implemented by a safety control module on the vehicle. Alternatively, they can be controlled via buttons on the vehicle or by a separate controller, such as... Figure 2 As shown, the airflow adjustment component can be controlled via the air conditioner control panel or air conditioner controller.

[0044] For example, the gas concentration value of the target gas in the target area inside the vehicle can be obtained, which can be obtained by a gas concentration monitoring unit. The monitoring unit can include at least one high-precision gas concentration sensor, and its installation position can cover the passenger compartment inside the vehicle. That is, the target area can be the passenger compartment area of ​​the vehicle.

[0045] For example, the aforementioned gas concentration sensor can be selected and configured for specific target gases, and can identify and detect the gas concentration of the target gas (including but not limited to propane, carbon dioxide, or other potentially hazardous gases). The gas concentration sensor possesses high sensitivity and fast response characteristics, ensuring the ability to capture subtle changes in gas concentration in the air, providing an accurate data basis for subsequent safety control.

[0046] For example, during vehicle operation, the gas concentration monitoring unit can perform continuous or periodic data acquisition operations. For instance, the aforementioned sensor can collect target gas molecule signals in the air of the target area in real time, converting them into electrical signals. The vehicle's air conditioning controller or dedicated safety control module receives the electrical signals from the sensor, processes them through an internal algorithm, and converts the electrical signals into specific gas concentration values. The processed value is the current gas concentration value. This current gas concentration value reflects the gas concentration of the target gas within the target area.

[0047] For example, if the current gas concentration is greater than or equal to a preset concentration threshold, it can be determined that there is a risk of leakage or accumulation of risky gas, and a safety control process can be triggered. Based on the vehicle's operating conditions, component control operations are performed to reduce the gas concentration of the target gas. The component control operations include at least one of the following: controlling the air duct guide component to switch to the exhaust state to connect the target area with the outside of the vehicle, wherein, in the exhaust state, the combination of the opening degree of the air inlet damper and the exhaust damper of the air duct guide component is dynamically adjusted according to the current vehicle speed; controlling the air volume regulating component to perform a reverse operation to exhaust the gas in the target area outside the vehicle.

[0048] For example, the preset safety threshold can be pre-set according to the type of refrigerant or the type of target gas. For example, for flammable R290 refrigerant, the safety threshold can be set to 10% to 15% of its lower explosive limit to achieve early warning; for R744 refrigerant, the safety threshold can be set to the concentration limit that affects human health.

[0049] For example, vehicle operating conditions may include, but are not limited to: vehicle driving state parameters, environmental and environmental interaction parameters, internal operating parameters of the air conditioning system, and internal state parameters of the passenger compartment. For example, vehicle operating conditions may include vehicle speed. The aforementioned vehicle operating conditions may be obtained through corresponding sensors or through other means, and this embodiment does not limit this.

[0050] For example, the air duct guide assembly can be controlled to perform corresponding opening and closing actions to construct an optimal exhaust airflow path. The adjustment logic for the damper opening can be set based on the aerodynamic characteristics of the vehicle during operation.

[0051] For example, the air volume regulating component can also be controlled to perform a reverse operation, that is, the air volume regulating component can be controlled to switch from the normal forward rotation mode to the reverse rotation mode.

[0052] For example, the airflow regulating component may include, but is not limited to, a blower, a differential pressure fan, a regular fan, etc. In this embodiment, the airflow regulating component may be a blower.

[0053] Here, the direction of reversal mentioned above can be the opposite of the rotation direction of the airflow adjustment component when the vehicle is in normal driving mode.

[0054] like Figure 3 As shown, during normal vehicle operation, there are both external and internal air circulation modes. When the recirculation air flap is open, it is in external circulation mode, driven by the blower to blow air into the passenger compartment, allowing outside air to continuously enter and maintain a constant supply of fresh air in the passenger compartment. When the recirculation air flap is closed, it is in internal circulation mode, driven by the blower to blow air into the passenger compartment, preventing outside air from entering and avoiding pollutants and poor-quality air from entering the passenger compartment. Currently, the air conditioning system features a blower controlled in unidirectional rotation, primarily for passenger cooling and heating. The airflow direction is always from the air outlet to the passenger compartment. That is, both the external and internal circulation modes are in forward rotation mode. In forward rotation, the blades push air from inside the air conditioning unit to the passenger compartment; in reverse rotation, the blades can draw air from inside the passenger compartment to the air conditioning unit and exhaust channels.

[0055] After the air duct guide component is adjusted to the corresponding exhaust state, that is, after the air volume adjustment component is reversed, the airflow direction can be changed to draw air from the passenger compartment to the blower and exhaust port, thereby creating a negative pressure environment in the passenger compartment and expelling air containing a high concentration of target gas outside the vehicle.

[0056] For example, the reverse rotation speed of the airflow regulating component can be dynamically adjusted according to the changing trend of gas concentration. For instance, when a continuous rise in gas concentration is detected or it is far above the safety threshold, the blower maintains the highest reverse rotation speed to quickly dilute the concentration; when the gas concentration begins to decrease, the reverse rotation speed can be appropriately reduced to save energy and reduce noise; when the gas concentration approaches the exit threshold, a low-frequency pulse reverse mode is adopted, that is, intermittent reverse rotation and stop alternating, to maintain a low concentration state in the chamber and reduce noise.

[0057] For example, when performing component control operations, the gas concentration value of the target gas can be continuously monitored. When the current gas concentration value drops below a preset exit threshold, the exhaust can be determined to be effective and exit the safety mode can be considered.

[0058] Based on steps S11 to S12 above, the current gas concentration value is obtained by acquiring the gas concentration value of the target gas in the target area inside the vehicle. When the current gas concentration value is greater than or equal to a preset concentration threshold, component control operations are executed according to the vehicle's operating conditions to reduce the gas concentration value of the target gas. The component control operations include at least one of the following: controlling the air duct guide component to switch to the exhaust state to connect the target area with the outside of the vehicle, wherein, in the exhaust state, the combination of the opening degree of the air inlet damper and the exhaust damper of the air duct guide component is dynamically adjusted according to the current vehicle speed; controlling the air volume adjustment component to perform a reverse operation to exhaust the gas in the target area outside the vehicle. This solves the problem of low safety in the vehicle control methods of related technologies and achieves the technical effect of improving vehicle safety.

[0059] The vehicle control method in the embodiments of this disclosure will be further described below.

[0060] Optionally, the vehicle is equipped with air inlets and exhaust outlets;

[0061] Based on the vehicle's operating conditions, execute component control operations, including:

[0062] When the vehicle's current speed is greater than a preset speed threshold, the control air duct guide component closes the air inlet and opens the exhaust outlet, and the control air volume adjustment component performs a reverse operation to discharge the target gas to the exhaust outlet.

[0063] When the vehicle's current speed is less than or equal to a preset speed threshold, the air duct guide component is controlled to open the air inlet and exhaust outlet, and the air volume regulating component is controlled to perform a reverse operation to discharge the target gas to the air inlet and exhaust outlet.

[0064] For example, a vehicle may be equipped with an air inlet and an exhaust outlet.

[0065] For example, consider the oncoming airflow naturally flowing towards the front of the vehicle when it is in motion. Therefore, the air intake can be located at the front of the vehicle (i.e., the hood), utilizing this natural airflow to make it easier and more efficient to draw in fresh air. For instance, it can be located below the front grille or windshield to introduce fresh air from outside the vehicle in external circulation mode. During normal driving, the air intake can generate a high positive pressure (dynamic pressure) due to the oncoming wind.

[0066] For example, the above-mentioned exhaust port can be as follows: Figure 4 As shown, it is located on the side of the vehicle. Since exhaust requires expelling air from inside the vehicle, the airflow direction is opposite to the direction of air intake. For situations where the air intake cannot also serve as an emergency exhaust outlet, an emergency exhaust outlet can be added on the side of the vehicle. This exhaust outlet can be closed in normal mode and opened in safety mode to expel air from inside the vehicle.

[0067] For example, one situation where the aforementioned air intake cannot be used as an emergency exhaust outlet is when the vehicle is traveling at high speed. When a vehicle is traveling at high speed, the airflow in front of the vehicle is fast and the static pressure is low, but the air hitting the air intake at the front of the vehicle is obstructed and forms a stagnation point, generating a high positive pressure. If the air intake is opened at this time and the blower is reversed, the high positive pressure at the front of the vehicle may offset the negative pressure of the blower, or even force outside air to flow back into the vehicle, reducing exhaust efficiency.

[0068] For example, when the vehicle's current speed exceeds a preset speed threshold, the air duct guide assembly can be controlled to close the air inlet and open the exhaust outlet, and the airflow regulation assembly can be controlled to reverse its operation to discharge the target gas to the exhaust outlet. For instance, air can be drawn from the passenger compartment by reversing the blower. Since the air inlet is closed, the air can be discharged through the side exhaust outlet, forming a unidirectional negative pressure exhaust flow. Under high-speed conditions, exhaust is carried out by the negative pressure generated by the blower and / or the side negative pressure generated by the vehicle's movement, ensuring a smooth exhaust path and preventing airflow short-circuiting or backflow.

[0069] For example, under low speed or stationary conditions, the positive pressure at the front of the vehicle is insufficient to cause backflow. Therefore, when the current vehicle speed is less than or equal to a preset vehicle speed threshold, the air duct guide component can be controlled to open the air inlet and exhaust outlet, and the air volume regulating component can be controlled to perform a reverse operation to discharge the target gas to the air inlet and exhaust outlet.

[0070] For example, a vehicle may be equipped with multiple side exhaust ports. In this case, the exhaust port closest to the leak source can be selectively opened according to the expected leakage area of ​​the target gas. That is, the exhaust port close to the leak source can be opened first and the exhaust port far away can be closed according to the location of the leak source (such as by sensor positioning or based on the structure of the air conditioning unit) to shorten the exhaust path and improve efficiency.

[0071] Based on the above optional embodiments, by determining vehicle speed and dynamically switching between single-sided and dual-sided exhaust, the aerodynamic characteristics of the vehicle can be utilized. This improves exhaust efficiency and safety under different operating conditions.

[0072] Optionally, when the vehicle's current speed is less than or equal to a preset speed threshold, the air duct guide assembly is controlled to open the air inlet and exhaust outlet, including:

[0073] When the current vehicle speed is less than or equal to a preset vehicle speed threshold, the air duct guide component is controlled to open the exhaust port, and the air duct guide component is controlled to open the air inlet according to the damper opening corresponding to the air inlet. The damper opening corresponding to the air inlet is negatively correlated with the current vehicle speed.

[0074] For example, after the reversal is triggered, the throttle opening can be matched according to the current vehicle speed.

[0075] Here, the damper opening refers to the displacement or rotation angle of the damper blade used to adjust the airflow channel relative to its fully closed or fully open position, and can be expressed as a percentage (e.g., 0% for fully closed, 100% for fully open). The damper mentioned above can be a rotary damper or a sliding damper; this embodiment does not limit the type.

[0076] When the vehicle is idling or traveling at low speed, the air dynamic pressure at the front air intake is low, insufficient to create a significant risk of backflow. At this time, completely closing the air intake and relying solely on the side exhaust outlets for negative pressure extraction may result in low ventilation efficiency. Therefore, the air intake can be opened appropriately. However, as the vehicle speed gradually increases, the airflow velocity increases, so the air intake opening should be reduced appropriately, in conjunction with the reverse rotation of the airflow control components, to maintain stable exhaust while reducing wind noise and energy consumption.

[0077] For example, the opening degree of the air intake damper can be determined based on the current vehicle speed through a preset mapping relationship or algorithm model. This opening degree is negatively correlated with the current vehicle speed; that is, the lower the vehicle speed, the larger the opening degree; and the higher the vehicle speed (within the low-speed range), the smaller the opening degree.

[0078] For example, the damper opening of the air inlet and the vehicle speed can be determined using a piecewise function or an S-curve. For instance, when the vehicle speed is below a first sub-threshold, a first preset opening (100%) is maintained to pursue exhaust efficiency; when the vehicle speed is above the first sub-threshold but below the second sub-threshold, the opening decreases linearly with the increase of vehicle speed.

[0079] For example, in addition to vehicle speed, the opening of the air inlet can also be affected by the current gas concentration. For instance, if the concentration is close to a safe level, the opening can be reduced in advance to save energy.

[0080] For example, considering that the air intake may contain multiple areas (such as the main air intake and the auxiliary air intake), the opening degree of the air damper in different areas can be controlled separately according to the vehicle speed. For example, when the vehicle speed is low, the main air intake and the auxiliary air intake are opened at the same time; when the vehicle speed is high, only the main air intake is opened or the auxiliary air intake is closed.

[0081] Based on the above optional embodiments, by using a fine adjustment strategy for the air inlet, the opening of the air inlet can be dynamically adjusted to adapt to the airflow characteristics under different driving conditions, thereby achieving a balance between exhaust efficiency and stability and improving vehicle safety.

[0082] Optionally, component control operations are performed according to the vehicle's operating conditions, including:

[0083] When the current gas concentration is less than the first concentration threshold, the air volume regulating component is controlled to periodically perform the first exhaust operation, wherein the first exhaust operation includes: first rotating in the reverse direction according to the first duty cycle, and then stopping the rotation, and the first concentration threshold is greater than the preset concentration threshold.

[0084] When the current gas concentration value is greater than or equal to the first concentration threshold and the current gas concentration value is less than the second concentration threshold, the air volume regulating component is controlled to periodically perform a second exhaust operation, wherein the second exhaust operation includes: first rotating in the reverse direction according to the second duty cycle, and then stopping the rotation, wherein the second duty cycle is greater than the first duty cycle;

[0085] When the current gas concentration is greater than or equal to the second concentration threshold, the airflow regulating component is controlled to rotate continuously in the reverse direction.

[0086] For example, a reverse-stop cycle pulse can be used, with a high duty cycle for medium concentration scenarios and a low duty cycle for maintaining low concentrations; the concentration is detected at each stop interval, and if the concentration rises, the continuous reverse rotation is immediately resumed. That is, even if the current gas concentration value is less than the first concentration threshold or the current gas concentration value is greater than or equal to the first concentration threshold and less than the second concentration threshold, if an upward trend in the current gas concentration value is detected, the mode of controlling the air volume adjustment component to rotate continuously in reverse can be switched.

[0087] For example, duty cycle refers to the ratio of the time the air volume regulating component rotates in the reverse direction to the total cycle time within a control cycle.

[0088] For example, when the current gas concentration is less than a first concentration threshold, the airflow regulating component can be controlled to periodically perform a first exhaust operation. This first exhaust operation includes: rotating in reverse according to a first duty cycle, then stopping the rotation. The first concentration threshold is greater than a preset concentration threshold. Since the concentration is low and below the first threshold, it indicates that the leakage is small or has been initially diluted, and full-power operation is unnecessary. Using a low-duty-cycle pulse mode can significantly reduce energy consumption and noise, improving the user experience.

[0089] For example, in the medium concentration range, that is, when the current gas concentration value is determined to be greater than or equal to the first concentration threshold and less than the second concentration threshold, the air volume regulating component can be controlled to first rotate in the opposite direction according to the second duty cycle and then stop rotating, the second duty cycle being greater than the first duty cycle.

[0090] For example, when it is determined that the current gas concentration value is greater than or equal to the second concentration threshold, the air volume regulating component can be controlled to continuously rotate in the reverse direction to improve exhaust efficiency.

[0091] For example, different thresholds and duty cycle references can be set for different types of refrigerants or different types of target gases.

[0092] Based on the above optional embodiments, by adopting an exhaust strategy of pulse reversal mode or continuous reversal based on the current gas concentration, a balance between exhaust efficiency, energy consumption and comfort can be achieved.

[0093] Optionally, the above method further includes:

[0094] Based on the concentration difference between the current gas concentration value and the historical gas concentration value, the trend of the gas concentration value of the target gas is determined. The historical gas concentration value is the gas concentration value collected at the time before the current gas concentration value is collected.

[0095] When the gas concentration of the target gas shows an upward trend, the air volume control component rotates in the opposite direction according to the first rotation speed.

[0096] When the gas concentration of the target gas shows a decreasing trend, the air volume control component rotates in the opposite direction at a second rotation speed, which is less than the first rotation speed.

[0097] In this embodiment, dynamic speed optimization can be performed based on the concentration change rate. That is, the concentration change rate dA / dt can be introduced as the basis for speed adjustment to achieve dynamic adaptation. For example, when the concentration continues to rise or is much higher than the safety threshold, the blower maintains the highest reverse speed to prioritize exhaust speed; when the concentration continues to drop steadily, the reverse speed is appropriately reduced to reduce energy consumption and noise while ensuring exhaust efficiency; when the concentration approaches the safety threshold, the speed is further reduced to smoothly transition and avoid repeated mode changes caused by concentration fluctuations.

[0098] For example, the trend of the target gas concentration value can be determined based on the concentration difference between the current gas concentration value and the historical gas concentration value, wherein the historical gas concentration value is the gas concentration value collected at the time preceding the current gas concentration value collection time.

[0099] Here, the gas concentration trend can refer to the characteristics of the accumulation state of the target gas in the passenger cabin over time. An upward trend means that the gas concentration increases per unit time, indicating that the leak is still ongoing or aggravating, and stronger exhaust capacity is needed to suppress further increases in concentration. A downward trend means that the gas concentration decreases per unit time, indicating that the leak may have stopped or been controlled, or that the exhaust system has taken effect. In this case, the exhaust intensity can be appropriately reduced to save energy and reduce noise.

[0100] For example, the above-mentioned collection time refers to the time point when the gas concentration sensor samples data, and the vehicle may have a fixed sampling period.

[0101] For example, the difference between the current gas concentration value and the historical gas concentration value can be calculated, and the trend of change can be judged based on the sign of the difference. If the difference is positive, it is determined to be a positive trend; if the difference is negative, it is determined to be a downward trend.

[0102] For example, if the current gas concentration value is greater than the historical gas concentration value of the previous period within a consecutive preset number of collection cycles, it can be determined as an upward trend; otherwise, it can be determined as a downward trend.

[0103] For example, the corresponding airflow adjustment component can be selected to reverse its rotation speed command based on the determined trend of change.

[0104] Based on the above optional embodiments, by monitoring the dynamic changes in gas concentration and intelligently adjusting the exhaust intensity of the air volume regulating component, trend-based adaptive control can be achieved, thereby improving energy utilization efficiency and vehicle safety.

[0105] Optionally, after performing component control operations based on the vehicle's operating conditions, the above method further includes:

[0106] When the gas concentration of the target gas is less than the preset concentration threshold, and the difference between the gas concentration of the target gas and the preset concentration threshold is greater than the preset concentration difference threshold, and the air volume regulating component rotates in the reverse direction, the air volume regulating component is controlled to rotate in the forward direction.

[0107] For example, a concentration determination strategy with hysteresis margin can be adopted, that is, when the concentration of harmful gas in the chamber meets A≤A0-a, the safe exhaust mode is exited. Here, A0 is the safe concentration threshold, and a is the hysteresis safety margin, which is used to avoid frequent mode switching caused by small fluctuations in concentration and to ensure the stability of the system.

[0108] For example, the aforementioned preset concentration difference threshold is the hysteresis margin. The purpose of setting this threshold is to introduce a hysteresis control mechanism to prevent the airflow adjustment component from frequently switching between forward and reverse rotation due to sensor noise or small concentration fluctuations, thereby ensuring the stability of system control and the lifespan of the actuator.

[0109] For example, if the gas concentration of the target gas is less than a preset concentration threshold, and the difference between the gas concentration of the target gas and the preset concentration threshold is greater than a preset concentration difference threshold, and the airflow regulating component rotates in the reverse direction, the reverse mode can be exited based on the detected target area temperature or passenger command, i.e., the rotation can be stopped. This embodiment does not limit this.

[0110] For example, before controlling the air volume regulating component to rotate in the forward direction, the changing trend of the gas concentration value of the target gas can also be determined; if the changing trend is a downward trend or a stable trend, then forward rotation control is executed; if the changing trend is an upward trend, then reverse rotation is maintained.

[0111] Based on the above optional embodiments, by introducing a dual determination mechanism of preset concentration threshold and preset concentration difference threshold, the exhaust mode can be robustly exited, avoiding frequent system start-stop due to concentration data fluctuations and improving vehicle safety.

[0112] Optionally, the target area includes the passenger compartment; the target gas includes at least one of the following: flammable refrigerant, non-flammable refrigerant, carbon monoxide, volatile organic compounds, and smoke;

[0113] Obtain the gas concentration value of the target gas in the target area inside the vehicle to obtain the current gas concentration value, including:

[0114] The gas concentration value of the target gas detected by the gas sensor is obtained to obtain the current gas concentration value. The gas sensor is installed in the passenger cabin and is used to detect the gas concentration value of the target gas.

[0115] For example, the target area mentioned above can refer to the interior space of a vehicle where air quality needs to be monitored in real time to ensure occupant safety, which can be the passenger compartment. There can be one gas sensor or multiple gas sensors within the target area; this embodiment does not limit this.

[0116] For example, the target gas may include, but is not limited to, at least one of the following: flammable refrigerants (such as R290 (propane), R600a (isobutane), etc.), non-flammable refrigerants (such as R744 (carbon dioxide), etc.), carbon monoxide, volatile organic compounds, and smoke.

[0117] For example, a single type of sensor can be configured, or an all-in-one sensor or a combination of multiple types of sensors can be configured to address different security scenarios.

[0118] For example, different exhaust strategies can be adopted for different types of target gases. For example, for flammable refrigerants, in order to suppress the risk of combustion and explosion, a safety linkage can be added to the exhaust system. When the safety mode is triggered, the high-pressure solenoid valve of the air conditioner is closed simultaneously to cut off the refrigerant circulation, limit the total leakage, send a signal to the vehicle body controller, temporarily close unnecessary high-voltage contacts in the vehicle (cigarette lighter, on-board fast charger, etc.), prevent the rapid raising and lowering of the windows to generate static electricity, reduce the risk of ignition, and directly reverse at full speed after triggering, without activating the pulse mode. Under idling conditions, the windows are simultaneously controlled to slightly lower to assist ventilation and accelerate the dilution of the concentration. For non-flammable refrigerants such as R744, in order to quickly dilute the hazardous gas and protect system components, and to adapt to its high-pressure and high-density characteristics, in addition to the concentration sensor, it can also be linked to the air conditioning high-pressure side pressure sensor. When the system pressure drops abnormally, even if the concentration does not meet the standard, it will trigger an early warning exhaust, providing a more proactive response. After triggering, it controls the refrigerant bypass valve to gradually balance the high and low pressure sides, while shutting down the compressor to avoid damage to pipelines and valves due to sudden pressure differences. Since R744 is denser than air and tends to accumulate at the bottom of the vehicle, the foot vents can be fully opened simultaneously during reverse exhaust, working with the blower to form a bottom-in, top-out airflow, improving the exhaust efficiency of high-concentration gas at the bottom. Since there is no risk of combustion or explosion, dynamic speed and pulse reverse strategy can be used normally, balancing energy consumption and noise performance.

[0119] Based on the above optional embodiments, by adopting corresponding sensor deployment and data acquisition methods for different target gas types, the accuracy and reliability of the exhaust scheme can be improved.

[0120] The vehicle control method in this application embodiment is explained below with reference to optional examples. In the vehicle control method of this optional example, the exhaust demand can be determined according to the overall vehicle operating conditions and the air quality inside the vehicle. At idle, exhaust can be carried out simultaneously through the air intake and exhaust ports. When driving, the air intake is closed, and exhaust is carried out only through the exhaust port. Unlike current air conditioning systems that can only achieve forward air supply, the reverse function of the blower can be used to create a negative pressure environment, accelerating the speed at which harmful gases are discharged from the passenger compartment. This feature significantly improves emergency response efficiency and is achieved through system control. The system integrates a high-precision gas concentration sensor and intelligent algorithm, which can monitor the air quality in the passenger compartment in real time. Once a refrigerant leak or excessive concentration of harmful gases is detected, the system will immediately activate the safety mode and reverse the blower to quickly discharge harmful air. This instant response mechanism significantly improves the ability to deal with emergencies, ensures that passenger health is not threatened, and can take action in the shortest possible time to avoid passengers being exposed to harmful environments for a long time. This feature is especially important during vehicle operation, as it can quickly reduce risks and ensure driving safety. Based on a preset safety threshold, the system can automatically switch to the safety mode without manual intervention. This not only simplifies the operation process but also ensures proper handling even when the driver is not paying attention. This feature is particularly useful in emergency situations, such as refrigerant leaks that may occur after a traffic accident. Considering the potential differences between different vehicle models, this solution emphasizes versatility and flexibility, ensuring easy integration into the vehicle's air conditioning architecture. It operates smoothly without adding any extra burden, regardless of whether other additional functional modules are installed.

[0121] Figure 5 This is a flowchart illustrating the vehicle control method in this optional example, such as... Figure 5 As shown, the control method for this vehicle can include the following steps: Detecting the vehicle's gas concentration A; if A > A0, it is assumed there is a need for exhaust in the passenger compartment, where A0 is a preset safety threshold. When the vehicle speed is 0, it can be determined that the vehicle is idling. Using the air conditioning remote control, the airflow flap can be adjusted to open both the air intake and exhaust ports, and the blower can be reversed until A ≤ A0 - a, at which point the exhaust mode is exited. If the vehicle speed is not 0, it is determined that the vehicle is in driving mode. The airflow flap can be adjusted to close the air intake and open the exhaust port, and the blower can be reversed until A ≤ A0 - a, at which point the exhaust mode is exited.

[0122] This optional example, by integrating advanced sensors and air quality algorithms (which quantify air pollution levels by calculating the Air Quality Index and setting three concentration ranges—early warning, activation, and emergency—with different exhaust intensities corresponding to different ranges)—can monitor in-vehicle air quality in real time and immediately activate a safety mode when an anomaly is detected. This intelligent response mechanism not only improves the speed of reaction to potential hazards but also reduces the possibility of human error, thereby better protecting occupants from harmful substances. This feature is particularly important for children, the elderly, and people with specific medical conditions, as it provides a safer and more comfortable driving environment. This embodiment not only supports the use of new environmentally friendly refrigerants but also dynamically adjusts its operating status according to actual needs, reducing unnecessary energy consumption and thus lowering overall carbon emissions. Furthermore, leveraging a cloud-based data analytics platform, valuable feedback on product performance can be fed back to the cloud for continuous improvement and design optimization (statistical analysis of leakage frequency, peak concentration, duration, and triggering scenarios under different vehicle models, regions / temperature and humidity environments, and operating conditions; locating high-risk leakage conditions and components; and reversibly optimizing air conditioning pipe sealing design and component selection; collecting exhaust duration, concentration reduction rate, and exhaust efficiency at different vehicle speeds for each safety mode; evaluating the control effect of current blower speed and damper opening; iteratively optimizing control parameters; and continuously improving exhaust efficiency). The safety mode introduced in this embodiment incorporates intelligent technology, enabling rapid purification of the cabin air when necessary, providing users with a fresher and healthier driving environment. Simultaneously, the system possesses learning capabilities, automatically adjusting settings based on user habits to provide a personalized service experience. For example, when the vehicle senses poor external air quality, it automatically switches to recirculation or safety mode to ensure optimal passenger comfort. This intelligent safety mode not only promptly handles refrigerant leaks, preventing equipment damage due to prolonged exposure to high refrigerant concentrations, but also reduces the complexity and cost of subsequent maintenance through predictive maintenance. The system's built-in self-diagnostic function can periodically check the working status of each component and issue an alert before potential problems are detected, reminding the owner to perform necessary maintenance or repairs. This not only reduces the probability of malfunctions but also extends the lifespan of the entire air conditioning system.
