Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to a control method, device, equipment, readable storage medium and vehicle for a pressure relief valve. Background Art

[0002] The pressure relief valve is a pressure release device, and the body pressure relief valve serves as an exchange channel for balancing the pressure inside and outside the vehicle. It is a key component that affects the ear pressure comfort when the vehicle door is closed, the noise level inside the vehicle, and the cold and hot comfort inside the vehicle.

[0003] The conventional pressure relief valve of a vehicle is a one-way valve that only allows air to be discharged from the passenger compartment. The air outside the vehicle cannot enter the vehicle through this valve. The pressure relief valve is usually kept closed under the action of gravity. When the pressure inside the vehicle is higher than the pressure outside the vehicle, the valve opens. Otherwise, the valve closes. The opening of the conventional pressure relief valve depends on the pressure difference between the inside and outside of the vehicle. The pressure relief valve will not open for pressure relief until the pressure difference between the inside and outside of the vehicle reaches a certain value. It cannot be opened in advance. Figure 1 As shown in the figure, during the door closing process, the pressure difference between the inside and outside of the car increases first. When the pressure difference between the inside and outside of the car reaches the opening threshold of the pressure relief valve, the pressure relief valve opens and begins to release pressure. The pressure difference between the inside and outside of the car decreases until the pressure relief is completed. Overall, the pressure difference between the inside and outside of the car fluctuates, first increasing and then decreasing. Figure 2 As shown in the figure, when the windows, sunroof and back door are all closed, the peak pressure at the driver's ear reaches 170Pa when the door is closed, affecting comfort. And when the vehicle air conditioner is in the external circulation working mode, the air conditioner pumps the air outside the car into the car, making the pressure inside the car higher than outside, and the pressure relief valve opens. However, since the opening of the pressure relief valve cannot be adjusted, and thus the flow of the pressure relief valve cannot be controlled, the air heated or cooled by the air conditioner all flows to the outside of the car, resulting in high energy consumption of the air conditioner. Summary of the invention

[0021] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0022] In one embodiment, see Figure 1 As shown, the present invention provides a control method for a pressure relief valve, which includes: The sealing state of the interior of the vehicle, the working mode of the vehicle air conditioner, and the corresponding relationship between the working mode of the vehicle air conditioner and the opening of the pressure relief valve are obtained.

[0023] In response to the vehicle interior being in an unsealed state, the pressure relief valve is controlled to be in an open state.

[0024] In response to the interior of the vehicle being in a sealed state, the pressure relief valve is controlled to a preset opening according to the working mode of the vehicle air conditioner and the corresponding relationship.

[0025] The present invention accurately obtains key parameters such as the sealing state of the interior of the vehicle and the working mode of the vehicle air conditioner, and realizes refined control of the opening of the pressure relief valve based on these parameters. Specifically, when it is detected that the interior of the vehicle is in an unsealed state, the pressure relief valve is immediately controlled to open. This measure has two advantages: first, it can significantly reduce the resistance during the closing process of the door and effectively reduce the difficulty of the door closing operation; second, it can effectively maintain the stability of the pressure in the car, avoiding the discomfort symptoms such as tinnitus caused by the sudden change of pressure, thereby greatly improving the passenger experience.

[0026] When the interior of the vehicle is in a sealed state, the present invention accurately adjusts the pressure relief valve to a preset opening according to the working mode of the vehicle air conditioner and the pre-established correspondence between the working mode of the vehicle air conditioner and the opening of the pressure relief valve. In this way, the pressure relief valve can be accurately regulated according to the impact of the air conditioner on the pressure inside the vehicle under different working modes, which can not only stabilize the pressure inside the vehicle and ensure the comfort of the interior environment, but also effectively reduce the energy consumption of the air conditioner and improve energy utilization efficiency, which meets the current development needs of the automotive industry for energy conservation, emission reduction and improved user experience.

[0027] It should be noted that the pressure relief valve described in the present invention adopts an active ventilation pressure relief device, which can adjust the opening of the pressure relief valve in real time according to control instructions to meet the pressure relief requirements of different application scenarios.

[0028] Furthermore, the step of obtaining the sealing state of the interior of the vehicle includes: When it is detected that a structural device that can make the vehicle not in a sealed state is in a closed state and the duration exceeds a preset time, the detection result is that the vehicle is in a sealed state, wherein the structural device that makes the vehicle not in a sealed state includes: doors, windows, sunroof and tailgate.

[0029] When it is detected that any one of the structural devices that can make the vehicle not in a sealed state is in a non-closed state, or when all the structural devices that can make the vehicle not in a sealed state are in a closed state and the duration does not exceed a preset time, the detection result is that the vehicle is in an unsealed state.

[0030] The present invention includes structural devices such as doors, windows, sunroofs and back doors that may destroy the sealing state of the vehicle into the detection scope, and comprehensively considers the common sealing-related components on the vehicle. If any of these components is not closed, it is very likely that a sealed space cannot be formed inside the vehicle. Through this comprehensive judgment method, the sealing state of the vehicle can be determined more accurately. At the same time, the present invention also introduces a duration judgment mechanism. When these structural devices are in a closed state, they must continue for more than a preset time before the vehicle is judged to be in a sealed state. This design effectively avoids the situation where the sealing state is frequently misjudged due to the short-term closure and opening of components. For example, the door may be closed briefly but not completely locked, and then opened again. If it is judged only based on the instantaneous state, it may be mistakenly believed that the vehicle is in a sealed state. The duration judgment mechanism makes the judgment more stable and reliable.

[0031] The present invention provides a key and precise parameter basis for the subsequent pressure relief valve control strategy by accurately obtaining the sealing state inside the vehicle. When the vehicle is in a sealed state, the pressure relief valve opening can be further accurately adjusted according to the air conditioning working mode; when the vehicle is in an unsealed state, the pressure relief valve is directly controlled to open to meet the needs of in-vehicle pressure control and passenger experience optimization under different sealing states.

[0032] The detection method described in the present invention can reflect the actual sealing condition of the vehicle in real time and accurately, provide a reliable basis for adjusting the internal environment of the vehicle, and ultimately improve the riding experience of passengers. For example, it can avoid the erroneous operation of the pressure relief valve due to misjudgment of the sealing status, causing unnecessary pressure change discomfort or difficulty in closing the door to the passengers. This detection method based on common vehicle structural devices is suitable for all types of vehicles with similar doors, windows, sunroofs and back doors, and has high versatility. Regardless of different models such as sedans, SUVs or MPVs, this method can be used to judge the sealing status inside the vehicle, which is convenient for promotion and application on different vehicle products.

[0033] As a preferred implementation of an embodiment of the present invention, in response to the interior of the vehicle being in a sealed state and the operating mode of the vehicle air conditioner being off or in internal circulation, the pressure relief valve is controlled to be in a closed state to prevent exhaust gas and dust outside the vehicle from entering the vehicle.

[0034] When the working mode of the vehicle air conditioner is closed or internal circulation, it means that the exchange of air inside the car and the outside air basically stops or is greatly reduced. At this time, if the interior of the vehicle is in a sealed state, the pressure inside the car is relatively stable, and there will be no large fluctuations due to the air conditioning system introducing outside air or exhausting the air inside the car. In this case, keeping the pressure relief valve closed can maintain a relatively stable pressure environment in the car and avoid destroying the pressure balance in the car due to unnecessary opening of the pressure relief valve. In addition, since the pressure relief valve is controlled to be closed in this scenario, unnecessary movements of the pressure relief valve are reduced, which helps to reduce the wear of the pressure relief valve and extend its service life. At the same time, from the perspective of energy saving, the opening of the pressure relief valve may cause a certain amount of energy loss (such as energy loss caused by air flow, etc.), and closing the pressure relief valve helps to further reduce energy consumption, which is consistent with the overall energy saving and emission reduction goals of the present invention.

[0035] When the vehicle is sealed and the air conditioner is turned off or in internal circulation, closing the pressure relief valve can maintain the stability of the pressure inside the vehicle, avoiding the slight pressure changes that may be caused by the opening of the pressure relief valve, reducing the discomfort caused by the pressure changes for passengers, and further improving the riding comfort of passengers. For example, in a relatively quiet vehicle environment, the slight airflow sound that may be generated by the opening of the pressure relief valve will also be avoided, thereby creating a quieter riding atmosphere.

[0036] As a preferred implementation of the embodiment of the present invention, in response to the interior of the vehicle being in a sealed state and the working mode of the vehicle air conditioner being an external circulation, the opening of the pressure relief valve is controlled according to the air volume of the air conditioner.

[0037] When the vehicle is in a sealed state and the air conditioner is in external circulation mode, outside air will continue to enter the car, causing the pressure inside the car to increase. By controlling the opening of the pressure relief valve according to the air volume of the air conditioner, the pressure changes caused by the introduction of air by the external circulation can be balanced in real time. Because the larger the air volume of the air conditioner, the more air enters the car per unit time, and the faster the pressure in the car rises, a larger pressure relief valve opening is needed to discharge excess air and maintain stable pressure. This control method accurately takes into account the direct relationship between the air volume of the air conditioner and the change in pressure inside the car in the external circulation mode. Compared with fixed opening control, it can more flexibly and accurately respond to pressure changes under different air volumes, ensuring that the pressure inside the car is always in a comfortable range.

[0038] Since the opening of the pressure relief valve corresponds to the air volume of the air conditioner, the pressure inside the car is always maintained in a stable state, avoiding ear discomfort, dizziness and other symptoms caused by pressure fluctuations. Whether it is rapid ventilation with large air volume or continuous ventilation with small air volume, passengers can feel the stable pressure environment inside the car, which improves the comfort of riding. And when the vehicle air conditioner is in external circulation mode, precise control of the opening of the pressure relief valve helps maintain moderate air circulation in the car, avoids air turbulence caused by pressure imbalance, creates a more comfortable air flow environment in the car, and reduces odor and stuffiness.

[0039] This preferred implementation is a further refinement of the overall pressure relief valve control strategy. Combined with the basic control method based on the vehicle sealing status and air-conditioning working mode, it provides a more targeted pressure relief valve opening control scheme for the specific and common air-conditioning working mode of external circulation, making the entire control system more perfect.

[0040] The pressure relief valve opening is dynamically adjusted according to the air volume of the air conditioner, while maintaining the stable pressure in the car, avoiding the increase of air conditioning energy consumption due to excessive or insufficient pressure relief. For example, when the air volume is small, the pressure relief valve opening is appropriately reduced to reduce unnecessary air discharge and reduce the energy consumption required by the air conditioner to maintain the temperature in the car, which is consistent with the goal of reducing air conditioning energy consumption of the present invention.

[0041] Air volume is an easily accessible parameter in the vehicle air conditioning system. The air conditioning control system of modern vehicles can monitor and feedback air volume information in real time. This makes it easy to obtain data and implement the control of the pressure relief valve opening based on the air volume in practical applications. Since data acquisition is real-time and convenient, the vehicle control system can quickly adjust the pressure relief valve opening according to the air volume changes, respond to the changes in the pressure inside the vehicle in a timely manner, and ensure that the vehicle can quickly stabilize the pressure inside the vehicle under various driving conditions and air conditioning usage scenarios.

[0042] Furthermore, the corresponding relationship between the air volume of the air conditioner and the opening of the pressure relief valve is determined by looking up a table.

[0043] The correspondence table between the air volume of the air conditioner and the opening of the pressure relief valve is obtained by calibration test, statistical modeling fitting, machine learning or simulation.

[0044] Exemplarily, the present invention determines the correspondence between the air conditioning air volume and the pressure relief valve opening through a calibration test, and can accurately measure based on the actual operating conditions and physical characteristics of the vehicle. During the test, the changes in the air conditioning air volume in various real scenarios and the corresponding changes in the pressure inside the vehicle can be simulated, so as to accurately find the pressure relief valve opening required to maintain the pressure inside the vehicle stable. Compared with theoretical calculations or empirical speculations, this correspondence based on actual tests is more in line with the actual situation of the vehicle, and can ensure that the pressure relief valve opening is effectively and accurately controlled in practical applications.

[0045] The calibration test can comprehensively consider the impact of different factors of the vehicle on the relationship between the air volume of the air conditioner and the opening of the pressure relief valve. For example, different models have different body structures, sealing performance, and air conditioning system characteristics. By conducting calibration tests on specific vehicles, these factors can be taken into consideration, making the determined correspondence highly targeted and accurate, providing strong support for the personalized design and optimization of vehicles.

[0046] The corresponding relationship determined based on the calibration test provides a reliable foundation for the entire pressure relief valve control system. During operation, the system can work stably based on the accurate corresponding relationship, reduce control fluctuations or abnormal conditions caused by inaccurate corresponding relationships, enhance the stability and reliability of the system, and reduce the risk of failure.

[0047] And the precise correspondence allows the pressure relief valve opening to be more accurately adjusted according to the air volume of the air conditioner. In actual operation, whether the air volume of the air conditioner changes slightly or fluctuates greatly, the pressure relief valve can make appropriate opening adjustments based on the established correspondence, thereby more effectively maintaining the stability of the pressure in the car and improving the comfort of passengers. At the same time, it also helps to improve the operating efficiency of the air conditioning system and further reduce energy consumption.

[0048] As a preferred implementation manner of the embodiment of the present invention, in response to a preset time period after the interior of the vehicle enters a sealed state from an unsealed state, the pressure relief valve is kept in an open state.

[0049] When the vehicle changes from an unsealed state to a sealed state, the pressure inside the vehicle will change due to the formation of the seal. Keeping the pressure relief valve open for a preset time can allow the pressure inside the vehicle to have a buffer transition stage, so that it can gradually reach a new balance with the external pressure. For example, in an unsealed state, the pressure inside the vehicle may be relatively close to the outside world. After a sudden seal, if it is not adjusted in time, the accumulation of small pressure differences may cause discomfort to passengers. Through this transition, drastic changes in pressure can be avoided. In addition, at the moment when the vehicle's sealing state changes, the air flow and pressure distribution inside the vehicle are in an unstable state. By keeping the pressure relief valve open for a preset time, it helps to stabilize the flow and redistribution of air inside the vehicle, so that the vehicle can better adapt to the transition from an unsealed state to a sealed state, and prepare for the subsequent precise control of the opening of the pressure relief valve or the closing of the pressure relief valve. It effectively avoids the instantaneous change in pressure caused by the sudden change in the vehicle's sealing state, thereby reducing the possibility of passengers experiencing discomfort symptoms such as tinnitus and stuffy ears. Especially for some passengers who are more sensitive to pressure changes, this smooth transition can significantly improve their riding comfort, so that passengers can hardly perceive obvious changes in pressure when the vehicle state changes. Since there is no obvious pressure fluctuation or abnormal sound when the vehicle's sealing state changes, it can create a more comfortable and stable riding environment for passengers, making passengers feel more secure psychologically and enhancing their recognition of the vehicle's quality.

[0050] It should be noted that the preset duration needs to be determined through experiments or simulation analysis based on the actual situation of the vehicle. If the duration is too short, the pressure balance transition may not be fully achieved; if the duration is too long, it may affect the normal pressure regulation of the vehicle in a sealed state and increase unnecessary energy consumption. Therefore, it is necessary to comprehensively consider factors such as the sealing performance of the vehicle, the size of the interior space, and the characteristics of the air-conditioning system to determine an optimal preset duration. For example, the preset duration is set to 3s.

[0051] This preferred implementation has good compatibility and is applicable to various types of vehicles. Regardless of the size, purpose, and sealing performance of the vehicle, the preset time can be adjusted to meet the pressure regulation requirements of different vehicles when they change from a non-sealed state to a sealed state, thereby enhancing the adaptability and versatility of the entire control strategy in practical applications.

[0052] As a preferred implementation of an embodiment of the present invention, in response to the interior of the vehicle being in a sealed state and the working mode of the vehicle air conditioner being in automatic mode, the opening of the pressure relief valve is controlled according to the real-time working state of the air conditioner.

[0053] The automatic mode of the vehicle air conditioner refers to: real-time monitoring of the temperature inside the vehicle through the temperature sensor inside the vehicle. When the temperature inside the vehicle is higher than the set temperature, the air conditioning system will automatically increase the cooling capacity to reduce the temperature inside the vehicle; conversely, when the temperature inside the vehicle is lower than the set temperature, the system will automatically turn on the heating function or reduce the cooling capacity to increase the temperature inside the vehicle so that the temperature inside the vehicle is always kept within the set comfortable range. And it will automatically adjust the air volume according to the difference between the temperature inside the vehicle and the set temperature. When the difference is large, the air conditioner will quickly adjust the temperature with a large air volume; as the temperature gradually approaches the set value, the air volume will automatically decrease to maintain a stable temperature and avoid excessive temperature fluctuations.

[0054] As a preferred implementation of the embodiment of the present invention, in response to the interior of the vehicle being in a sealed state and the air conditioner being in nap mode (people resting in the vehicle), if the ambient temperature is detected to be suitable (17-24°C), the air conditioner is turned off and the pressure relief valve is controlled to be in an open state, that is, the pressure relief valve opening is controlled to be 100% to ensure comfort in the vehicle. If the ambient temperature is detected to be unsuitable (that is, the ambient temperature is lower than 17°C or higher than 24°C), the air conditioner is turned on, so that the air conditioner is in an automatic mode of 25°C, and the pressure relief valve opening is controlled according to the real-time working state of the air conditioner.

[0055] In another embodiment, the present invention further provides a control device for a pressure relief valve, see Figure 4As shown, the device includes an acquisition module 10, a storage module 20, a first control module 30 and a second control module 40. The acquisition module 10 is used to acquire the sealing state of the interior of the vehicle and the working mode of the vehicle air conditioner, and the storage module 20 is used to store the corresponding relationship between the working mode of the vehicle air conditioner and the opening of the pressure relief valve. The first control module 30 is used to control the pressure relief valve to be in an open state when the interior of the vehicle is in an unsealed state; the second control module 40 is used to control the pressure relief valve to a preset opening according to the working mode of the vehicle air conditioner and the corresponding relationship when the interior of the vehicle is in a sealed state.

[0056] In another embodiment, the present invention further provides a computer device, comprising: a memory and a processor, wherein the memory and the processor are communicatively connected to each other, computer instructions are stored in the memory, and the processor executes the above-mentioned pressure relief valve control method by executing the computer instructions.

[0057] In yet another embodiment, the present invention further provides a vehicle, which includes the above-mentioned computer device.

[0058] In yet another embodiment, the present invention further provides a computer-readable storage medium, on which computer instructions are stored, and the computer instructions are used to enable a computer to execute the above-mentioned pressure relief valve control method.

Any equivalent substitution or change made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
