Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of vehicles, and particularly relates to a control method and device of a pressure relief valve, equipment, medium, vehicle-mounted device and vehicle. BACKGROUND

[0002] Vehicles are increasingly popular in people's daily life, 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 in the vehicle and improve the driving experience.

[0003] In related technologies, the pressure relief valve is usually arranged on the vehicle body sheet metal behind the rear bumper of the vehicle. When the pressure in the vehicle is large, the air in the vehicle flows out of the vehicle through the pressure relief valve to achieve pressure relief. Since the pressure relief valve can be bidirectionally conducted, water and the like cannot be prevented from entering the vehicle, thereby causing water and other external substances to enter the vehicle through the pressure relief valve in a water-related scenario, which causes the vehicle body sheet metal or electronic devices to rust and be damaged.

[0004] To overcome the above problems, the pressure relief valve can be closed in a water-related scenario to protect the sheet metal and electronic devices, but this will cause the air to be unable to flow out of the vehicle when the pressure in the vehicle is large, thereby causing poor driving experience.

[0085] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the solutions 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 in order to provide a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other different manners than those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0087] The control method of the pressure relief valve provided by the embodiments of the present disclosure can be applied to scenarios such as wading, high-concentration dust, user self-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 a control signal for the first pressure relief valve and the second pressure relief valve is generated by identifying the detection signal of the obtained target parameter, so that in the scenario where vehicle protection is needed, 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 in an open state, thereby retaining the pressure relief valve with a higher height to perform vehicle pressure relief, and using the pressure relief valve with a lower height to achieve vehicle protection, which can balance vehicle protection and driving experience.

[0088] In other embodiments, in other working condition scenarios, such as when the water level is too high and the vehicle driving experience cannot be balanced, the first pressure relief valve and the second pressure relief valve can also be set to be closed; or when the water level is too low and vehicle protection is not needed, the first pressure relief valve and the second pressure relief valve can also be set to be opened, which is not limited herein.

[0089] The control method, device, equipment, medium, vehicle-mounted device and vehicle provided by the embodiments of the present disclosure will be exemplarily described below with reference to the accompanying drawings.

[0090] Exemplarily, Figure 1 The flowchart of the control method of the pressure relief valve provided by the embodiments of the present disclosure can be executed by a control device, which can be realized in the form of software and / or hardware. Exemplarily, the control device can be a vehicle-mounted controller or other controller in communication with the vehicle. Referring to Figure 1 The control method comprises the following steps:

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

[0092] The target parameter is a parameter representing the environment in which the vehicle is currently located, the environment in which the vehicle is located, or the intention of the user for the operation of the vehicle, is related to the opening and closing control of the pressure relief valve, and can exemplarily include at least one of a water level, dust, a vehicle start-stop state, and a user instruction.

[0093] Exemplarily, when the vehicle is in a wading scene or a scene with a high concentration of dust, it is necessary to close some pressure relief valves to balance the needs of vehicle protection and air pressure inside and outside the vehicle; or, when the vehicle switches from a start state to a stop state, to avoid the influence of the external environment on the vehicle, and to ensure the balance of the pressure inside and outside the vehicle, some pressure relief valves can be closed; or, according to the user instruction, some pressure relief valves can be closed in a specific vehicle condition or scene to protect the vehicle while ensuring the balance of the air pressure inside and outside the vehicle, which will be described in detail below.

[0094] S120, generating a control signal of the pressure relief valve based on the detection signal and the preset correlation.

[0095] The preset correlation is the correlation 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 be closed and at least one second pressure relief valve to remain in an open state; wherein the first pressure relief valve is set at a lower height than the second pressure relief valve.

[0096] Exemplarily, Figure 2 A layout mode of a pressure relief valve provided by an embodiment of the present disclosure is shown. As shown in Figure 2 The number and setting height of the pressure relief valve in the related art are improved in the embodiment of the present disclosure. At least two pressure relief valves with different layout heights, i.e., a second pressure relief valve 602 with a higher setting height and a first pressure relief valve 601 with a lower height, are provided, so that only some of the pressure relief valves can be closed, for example, the first pressure relief valve 601 is closed while the second pressure relief valve 602 remains in an open state. Thus, while the vehicle is protected to a certain extent, the pressure inside the vehicle can be discharged based on the second pressure relief valve 602 in the open state, thereby ensuring the comfort of driving and riding.

[0097] It should be noted that Figure 2 The number of the first pressure relief valve 601 and the second pressure relief valve 602 is exemplarily shown as one in the embodiment, 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 there can be two or more of them. In addition, three or more pressure relief valves at different heights can also be provided, and the opening and closing control can be performed based on the detection signal to meet the balance needs of vehicle protection and driving and riding comfort, which is not limited herein.

[0098] In the embodiments of the present disclosure, at least one first pressure relief valve and at least one second pressure relief valve with different heights are arranged, and the detection signals of the obtained target parameters are identified to generate control signals for the first pressure relief valve and the second pressure relief valve, so that in the scene requiring vehicle protection, 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 in an open state, thereby retaining the pressure relief valve with a higher height to perform vehicle pressure relief, and using the pressure relief valve with a lower height to achieve vehicle protection, which can balance vehicle protection and driving experience.

[0099] The implementation of the embodiments of the present disclosure will be exemplarily described below with respect to different target parameters.

[0100] In some embodiments, the target parameter is a water level, and the water level can be detected based on a water level sensor, and the opening and closing control of the pressure relief valve is realized to balance the demand for vehicle protection and driving comfort in a water crossing scene.

[0101] Exemplarily, based on the above, Figure 1 S110 can specifically include:

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

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

[0104] Exemplarily, Figure 3 The structure of a vehicle-mounted device provided by an embodiment of the present disclosure is shown. As shown in Figure 3 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; thus, when the vehicle is in water, the corresponding pressure relief valve can be closed based on the water level signal detected by the water level sensor, thereby avoiding water entering the vehicle to protect the vehicle.

[0106] In the embodiments of the present disclosure, for the pressure relief valves with different setting heights, water level sensors with corresponding heights are arranged respectively. When the vehicle is wading 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 be closed to avoid water entering the vehicle, thereby protecting the vehicle. At this time, the second pressure relief valve 602 with a higher setting height can still remain in an open state, thereby facilitating the pressure relief of the vehicle interior and ensuring a better driving experience.

[0107] Thus, in some embodiments, based on the above, Figure 1 S120 can specifically include:

[0108] determining the current water level in which the vehicle is located based on the detection signal;

[0109] based on the current water level in which the vehicle is located and the preset correlation relationship, determining that when the current water level in which the vehicle is located is between the first water level sensor and the second water level sensor, the control signal is generated when the first water level sensor is reached.

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

[0111] It should be noted that, Figure 3 only one water level sensor with the same height is exemplarily shown in the above, in other embodiments, in order to improve the detection accuracy, two, three or more water level sensors with the same height can also be arranged, and the signals collected by the water level sensors with the same height are processed mathematically to obtain the detection signal, which is beneficial to improve the accuracy of the detection signal.

[0112] In some embodiments, the detection signal for the water level is obtained, specifically can include:

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

[0114] based on the signals collected by the at least two first water level sensors, performing numerical average processing, and / or based on the signals collected by the at least two second sensors, performing data average processing to determine the detection signal.

[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 (here, the "corresponding height" means that the height is substantially equal to the height of the pressure relief valve, and slightly lower than the height of the pressure relief valve) can be set; 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 subjected to numerical average processing, and the average height obtained by the processing is taken as the detection signal; or the average height is obtained by averaging the reliable heights after removing the unreliable heights, and the average height is taken as the water level signal.

[0116] In other embodiments, when the number of water level sensors set for the same pressure relief valve is at least two, other data processing methods can also be used to obtain the corresponding detection signal, which is not limited herein, so as to improve the accuracy of the detection signal and the control accuracy of the pressure relief valve.

[0117] The above describes the optional implementation of the detection signal acquisition and the control signal generation by taking the water level sensor as an example for the vehicle wading.

[0118] The following describes the optional implementation of the detection signal acquisition and the control signal generation when wading or the dust concentration is high by taking the image sensor as an example.

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

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

[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 and within the preset distance range from the pressure relief valve, the environmental parameters near the pressure relief valve can be accurately acquired, thereby facilitating the accurate control of the pressure relief valve.

[0123] Illustratively, the preset distance range can be within 1 centimeter or other distance ranges, which are not limited herein.

[0124] In the embodiments of the present disclosure, the image sensor can collect the environmental image and transmit it to the control device; the control device receives the environmental image and identifies it to obtain the detection signal for the water level and / or the dust, so as to be subjected to subsequent processing.

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

[0126] Based on the detection signal, it is determined that the current water level of the vehicle reaches a preset position, and 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 is less than or equal to the critical protection distance.

[0127] Specifically, the control device identifies the image obtained by the image sensor to obtain a detection signal; when the detection signal indicates that the vehicle is wading and the current water level reaches the 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 achieve protection of the vehicle. The preset position is substantially 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 realizing the protection of the vehicle wading. In the above, the distance between the preset position and the first pressure relief valve is limited by the critical protection distance, and the critical protection distance can be 1 centimeter or other distance values, which are not limited herein.

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

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

[0130] Specifically, the control device identifies the image obtained by the image sensor to obtain a detection signal; when the detection signal indicates that the vehicle is in a harsh environment, for example, the current dust concentration of 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 part of the pressure relief valve is kept in an open state, thereby preventing a large amount of dust from entering the vehicle and achieving protection of 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 herein.

[0131] The above describes the optional implementation of the detection signal acquisition and the control signal generation for the vehicle wading and / or being in a dust environment, taking the image sensor as an example.

[0132] The following describes the optional implementation of the detection signal acquisition and the control signal generation for the vehicle start-stop state and the user instruction in combination with the signals transmitted by the signal bus.

[0133] In some embodiments, the target parameter is the start-stop state of the vehicle; in Figure 1 On the basis of the above, S110 can specifically include: based on the signals transmitted by the signal bus, acquiring a detection signal for the start-stop state of the vehicle; S120 can specifically include: based on the detection signal, determining that the start-stop state of the vehicle is switched from moving to stopping, and generating a control signal.

[0134] Specifically, the module for enabling and stopping control of the vehicle is connected with the control device through a signal bus and transmits a detection signal for a starting and stopping state of the vehicle to the control device. The control device acquires the detection signal and generates a control signal to control the first pressure relief valve to be closed and the second pressure relief valve to be kept in an open state when it is identified that the vehicle is switched from moving to stopping, so that water, dust, lint and the like at a lower height can be prevented from entering the vehicle, and the second pressure relief valve can be used to release the pressure in the vehicle to the outside, thereby avoiding a poor experience in the initial stage of the next driving and riding, and user experience is taken into account.

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

[0136] Specifically, the user can observe the environment around the vehicle and, when the vehicle needs to enter the protection mode, perform information interaction with the information interaction module, so that the control device acquires a corresponding detection signal for a user instruction and generates a control signal in response to a selection operation of the user for the protection mode. Exemplarily, the protection mode can include at least one of water crossing protection, dust protection, parking protection and the like.

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