Description

Technical Field

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

[0002] Vehicles are becoming increasingly popular in people's daily lives, and people's requirements for driving experience are also increasing. For example, by setting a pressure relief valve, the inside and outside of the vehicle can be connected to adjust the pressure inside the vehicle and improve the driving experience.

[0003] In the related art, the pressure relief valve is usually installed on the body sheet metal behind the rear bumper of the vehicle. When the pressure inside the vehicle is high, the air inside the vehicle flows out of the vehicle through the pressure relief valve to achieve pressure relief. Since the pressure relief valve can be bidirectional, it cannot prevent water and other substances from entering the vehicle. As a result, in scenes such as wading, water and other external substances can enter the vehicle through the pressure relief valve, causing the sheet metal or electronic devices inside the vehicle to rust and be damaged.

[0004] To overcome the above problems, the pressure relief valve can be closed in water-crossing scenarios to protect sheet metal and electronic devices, but this will result in the air being unable to flow out of the car when the pressure inside the car is high, resulting in a poor driving experience.

[0085] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0086] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0087] The control method of the pressure relief valve provided in the embodiment of the present disclosure can be applicable to scenarios such as wading, high-concentration dust, user autonomous control and vehicle automatic control. Specifically, at least one first pressure relief valve and at least one second pressure relief valve with different heights are set, and the detection signal of the acquired target parameter is identified to generate control signals for the first pressure relief valve and the second pressure relief valve. Therefore, in a scenario where vehicle protection is required, the first pressure relief valve with a lower height is controlled to be closed, and the second pressure relief valve with a higher height is kept open, thereby retaining the pressure relief valve with a higher height for vehicle pressure relief, and using the pressure relief valve with a lower height to achieve vehicle protection, which can take into account both vehicle protection and driving experience.

[0088] In other embodiments, in other operating scenarios, for example, when the water level is too high and the vehicle driving experience can no longer be taken into account, the first pressure relief valve and the second pressure relief valve may be set to be closed; or when the water level is too low and there is no need to consider vehicle protection, the first pressure relief valve and the second pressure relief valve may be set to be opened, which is not limited here.

[0089] In conjunction with the accompanying drawings, the control method, device, equipment, medium, vehicle-mounted device and vehicle of the pressure relief valve provided in the embodiments of the present disclosure are exemplarily described below.

[0090] For example, Figure 1 A flow chart of a method for controlling a pressure relief valve provided in an embodiment of the present disclosure can be executed by a control device, which can be implemented in the form of software and / or hardware; illustratively, the control device can be a vehicle-mounted controller or other controller that communicates with the vehicle. Figure 1 , the control method comprises the following steps:

[0091] S110, obtaining a detection signal of a target parameter.

[0092] Among them, the target parameter is a parameter that characterizes the current vehicle environment, the vehicle environment or the user's intention to operate the vehicle, and is related to the switch control of the pressure relief valve. It may exemplarily include at least one of water level, dust, vehicle start / stop status and user instructions.

[0093] For example, when the vehicle is in a wading scene or a scene with a high dust concentration, it is necessary to close some pressure relief valves to balance the needs of vehicle protection and the air pressure inside and outside the vehicle; or, when the vehicle switches from a starting state to a parking state, in order to avoid the influence of external locations on the interior of the vehicle and to ensure the pressure balance inside and outside the vehicle, some pressure relief valves can be closed; or, in response to user instructions, some pressure relief valves can be closed under specific vehicle conditions or scenarios to achieve protection of the vehicle and ensure the air pressure balance inside and outside the vehicle, as described in detail below.

[0094] S120: Generate a control signal for the pressure relief valve based on the detection signal and the preset association relationship.

[0095] Among them, the preset association relationship is the association relationship between the detection signal and the control signal, and the control signal includes a signal for controlling at least one first pressure relief valve to close and at least one second pressure relief valve to remain in an open state; wherein the setting height of the first pressure relief valve is lower than the setting height of the second pressure relief valve.

[0096] For example, Figure 2 FIG. 2 shows a layout of a pressure relief valve provided by an embodiment of the present disclosure. Figure 2 As shown, in the embodiment of the present disclosure, the number and setting heights of the pressure relief valves in the related art are improved, by arranging at least two pressure relief valves with different heights, namely, a second pressure relief valve 602 with a higher setting height and a first pressure relief valve 601 with a lower height, so that only some of the pressure relief valves can be closed, for example, the first pressure relief valve 601 can be closed, while the second pressure relief valve 602 is kept in an open state; thereby, while providing a certain degree of protection to the vehicle, the pressure inside the vehicle can also be leaked based on the second pressure relief valve 602 in an open state, thereby ensuring driving comfort.

[0097] It should be noted that Figure 2 It is only exemplarily shown that the number of the first pressure relief valve 601 and the second pressure relief valve 602 are both one, and they are arranged on the same side of the rear of the vehicle; in other embodiments, the first pressure relief valve 601 and the second pressure relief valve 602 can also be arranged at other positions of the vehicle, and two or more pressure relief valves can be arranged; in addition, three or more pressure relief valves at different heights can be arranged, and the switch control can be performed based on the detection signal to meet the balance requirements of vehicle protection and driving comfort, which is not limited here.

[0098] In the embodiment of the present disclosure, by setting at least one first pressure relief valve and at least one second pressure relief valve of different heights, and by identifying the detection signals of the acquired target parameters, control signals for the first pressure relief valve and the second pressure relief valve are generated, so that in a scenario where vehicle protection is required, the first pressure relief valve with a lower height is controlled to be closed, and the second pressure relief valve with a higher height is kept open, thereby retaining the pressure relief valve with a higher height to relieve vehicle pressure, and utilizing the pressure relief valve with a lower height to achieve vehicle protection, which can take into account both vehicle protection and driving experience.

[0099] The following is an illustrative description of the implementation methods of the embodiments of the present disclosure with respect to different target parameters.

[0100] In some embodiments, the target parameter is the water level, which can be detected based on a water level sensor, and the switch control of the pressure relief valve can be realized to take into account the needs of vehicle protection and driving comfort in wading scenarios.

[0101] For example, in Figure 1 On the basis of, S110 may specifically include:

[0102] Based on the water level sensor, a detection signal for the water level is obtained.

[0103] Among them, corresponding water level sensors are respectively set for pressure relief valves with different setting heights, so as to determine the detection signal based on the signal detected by the water level sensor, and generate a control signal for switching control of the pressure relief valve.

[0104] For example, Figure 3 The structure of a vehicle-mounted device provided by an embodiment of the present disclosure is shown. Figure 3 As shown, the water level sensor 603 includes at least one first water level sensor 6031 for the first pressure relief valve 601 and at least one second water level sensor 6032 for the second pressure relief valve 602; the setting height of the first water level sensor 6031 is lower than the setting height of the first pressure relief valve 601, the setting height of the second water level sensor 6032 is lower than the setting height of the second pressure relief valve 602, and the setting height of the first water level sensor 6031 is lower than the setting height of the second water level sensor 6032.

[0105] Among them, the height of the water level sensor is basically equal to the height of the corresponding pressure relief valve, and slightly lower than the height of the pressure relief valve; therefore, when the vehicle wades through water, the corresponding pressure relief valve can be closed when the water level sensor detects a water level signal, thereby preventing water from entering the vehicle and protecting the vehicle.

[0106] In the embodiment of the present disclosure, water level sensors with corresponding heights are respectively set for the pressure relief valves with different setting heights. When the vehicle wades and the water level reaches the water level sensor with a lower height, i.e., the first water level sensor 6031, the corresponding first pressure relief valve 601 can be controlled to close to prevent water from entering the vehicle, thereby protecting the vehicle; and, at this time, the second pressure relief valve 602 with a higher setting height can still remain in an open state, thereby facilitating the leakage of internal pressure of the vehicle and ensuring a better driving experience.

[0107] Thus, in some embodiments, Figure 1 On the basis of, S120 may specifically include:

[0108] determining a current water level of the vehicle based on the detection signal;

[0109] Based on the current water level of the vehicle and the preset association relationship, when it is determined that the current water level of the vehicle is between the first water level sensor and the second water level sensor and reaches the first water level sensor, a control signal is generated.

[0110] The control signal is used to control the first pressure relief valve to close and the second pressure relief valve to remain open, thereby taking into account the needs of vehicle protection and driving comfort.

[0111] It should be noted that Figure 3 It is only shown by way of example that the number of water level sensors at the same height is one. In other embodiments, in order to improve the detection accuracy, two, three or more water level sensors may be arranged at the same height, and the detection signal may be obtained by performing mathematical processing on the signals collected by the water level sensors at the same height, which is beneficial to improving the accuracy of the detection signal.

[0112] In some embodiments, obtaining a detection signal for a water level may specifically include:

[0113] Acquire signals collected by at least two first water level sensors provided for the first pressure relief valve, and / or acquire signals collected by at least two second water level sensors provided for the second pressure relief valve;

[0114] The detection signal is determined by performing numerical averaging processing based on signals collected by at least two first water level sensors and / or performing data averaging processing based on signals collected by at least two second sensors.

[0115] Specifically, for at least one of the pressure relief valves with different setting heights, at least one water level sensor with a corresponding height (the "corresponding height" here is basically equal to the height in the above text and slightly lower than the height of the pressure relief valve) can be set in a targeted manner; when the number of water level sensors is one, the signal collected by the water level sensor can be directly converted into a detection signal of the corresponding water level height; when the number of water level sensors is two or more, the water level heights corresponding to the signals collected by the two or more water level sensors can be numerically averaged, and the average height obtained by the processing can be used as the detection signal; or after removing the unreliable height, the obtained reliable heights can be averaged to obtain the average height, and the average height can be used as the water level signal.

[0116] In other embodiments, when the number of water level sensors provided for the same pressure relief valve is at least two, other data processing methods may be used to obtain corresponding detection signals, which are not limited here, to improve the accuracy of the detection signals, thereby improving the control accuracy of the pressure relief valve.

[0117] The above description uses a water level sensor as an example to illustrate the optional implementation methods for acquiring detection signals and generating control signals for vehicle wading.

[0118] The following describes the optional implementation methods of acquiring detection signals and generating control signals when wading through water or when the dust concentration is high, in conjunction with the image sensor.

[0119] In some embodiments, the target parameter is water level and / or dust; Figure 1 On the basis of, S110 may specifically include:

[0120] Based on the image sensor, a detection signal for water level and / or dust is obtained.

[0121] The image sensor is arranged on the outside of the vehicle and within a preset distance range from the pressure relief valve.

[0122] Specifically, by arranging the image sensor on the outside of the vehicle within a preset distance range from the pressure relief valve, it is helpful to accurately obtain environmental parameters near the pressure relief valve, thereby facilitating accurate control of the pressure relief valve.

[0123] Exemplarily, the preset distance range may be within 1 centimeter or other distance ranges, which are not limited here.

[0124] In the disclosed embodiment, the image sensor can collect environmental images and transmit them to the control device; the control device receives and identifies the environmental images to obtain detection signals for water level and / or dust for subsequent processing.

[0125] In some embodiments, Figure 1On the basis of, S120 may specifically include:

[0126] Based on the detection signal, when it is determined that the current water level of the vehicle reaches a preset position, a control signal is generated; the preset position is a position lower than the first pressure relief valve and the distance between the first pressure relief valve and the first pressure relief valve is less than or equal to the critical protection distance.

[0127] Specifically, the control device recognizes the image acquired by the image sensor and obtains a detection signal; when the detection signal indicates that the vehicle is wading and the current water level reaches a preset position, a control signal is generated to control the first pressure relief valve to close, so as to prevent water from entering the vehicle and protect the vehicle. The preset position is basically consistent with the position of the first pressure relief valve and is slightly lower than the position of the first pressure relief valve, which can be understood as a critical position for achieving vehicle wading protection. The critical protection distance is used to define the distance between the preset position and the first pressure relief valve. For example, the critical protection distance can be 1 cm or other distance values, which are not limited here.

[0128] In some embodiments, Figure 1 On the basis of, S120 may specifically include:

[0129] When it is determined based on the detection signal that the current dust concentration of the vehicle reaches a preset concentration, a control signal is generated.

[0130] Specifically, the control device recognizes the image acquired by the image sensor and obtains a detection signal; when the detection signal indicates that the vehicle is in a harsh environment, for example, when the current dust concentration in the environment where the vehicle is located reaches a preset concentration, a control signal is generated to control the first pressure relief valve or the second pressure relief valve to close, and keep some pressure relief valves in an open state, thereby preventing a large amount of dust from entering the vehicle and protecting the vehicle. The preset concentration can be set according to the control method and the protection requirements of the vehicle, and its specific value is not limited here.

[0131] In the above, for a vehicle wading through water and / or in a dusty environment, an image sensor is taken as an example to exemplarily illustrate optional implementation methods for acquiring detection signals and generating control signals.

[0132] The following describes the optional implementation methods of acquiring detection signals and generating control signals for vehicle start / stop status and user commands in conjunction with the signals transmitted by the signal bus.

[0133] In some embodiments, the target parameter is the vehicle start / stop state; Figure 1 On the basis of, S110 may specifically include: based on the signal transmitted by the signal bus, obtaining a detection signal for the start-stop state of the vehicle; S120 may specifically include: when it is determined based on the detection signal that the start-stop state of the vehicle is switched from motion to stop, generating a control signal.

[0134] Specifically, the vehicle start-stop control module is connected to the control device through a signal bus, and the detection signal for the vehicle start-stop status is transmitted to the control device. The control device obtains the detection signal and, when it recognizes that the vehicle switches from motion to stop, generates a control signal to control the first pressure relief valve to close and the second pressure relief valve to remain open; thereby, water, dust, hair, etc. at a lower height can be prevented from entering the vehicle. At the same time, the second pressure relief valve can be used to release the greater pressure in the vehicle to the outside, thereby avoiding the problem of poor experience in the initial stage of the next driving, thereby taking into account the user experience.

[0135] In some embodiments, the target parameter is a user instruction; Figure 1 On the basis of, S110 may specifically include: based on the user's selection operation for the protection mode received by the information interaction module, obtaining a detection signal for the user's instruction; S120 may specifically include: when determining based on the detection signal that the user's instruction is associated with controlling the vehicle to enter the protection mode, generating a control signal.

[0136] Specifically, the user can observe the environment around the vehicle, and when the vehicle needs to enter the protection mode, the user can interact with the information interaction module, so that the control device responds to the user's selection operation for the protection mode, obtains the corresponding detection signal for the user's instruction, and generates a control signal. Exemplarily, the protection mode may include at least one of wading protection, dust protection, parking protection, etc.

[0137] In the above embodiment, when the water level is too high, for example, reaches the position of the second water level sensor, or the dust concentration is too high, or based on user operation, the second pressure relief valve may be further closed, which is not limited here.
