Description

Technical Field

[0001] This application relates to the field of automotive electronics technology, specifically to a tailgate control method, system, and vehicle. Background Technology

[0002] Most cars on the market are equipped with pressure sensor tailgate switches to control the opening and closing state of the tailgate. The working principle of the pressure sensor tailgate switch is: the pressure sensor detects the pressure signal on the outer surface of the tailgate, and when the pressure signal exceeds the preset threshold, the tailgate is triggered to open automatically.

[0003] However, existing pressure sensor tailgate switches rely solely on pressure signals for triggering and cannot identify the pressing mechanism on the outer surface of the tailgate, leading to many false opening issues. For example, in a car wash scenario, when high-pressure water jets impact the outer surface of the tailgate, they generate pressure signals similar to those of a human hand pressing, causing the tailgate to open unexpectedly, resulting in property damage and safety risks. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides the following technical solutions.

[0005] This application provides a tailgate control method, including the following steps:

[0006] Acquire the pressure signal applied to the outer surface of the vehicle's tailgate;

[0007] Determine the pressing body represented by the pressure signal;

[0008] The opening and closing state of the vehicle's tailgate is controlled by the pressing body.

[0009] Optionally, the pressing body representing the pressure signal includes:

[0010] Determine the corresponding pressure curve based on the pressure signal;

[0011] Obtain pressure parameters of a preset type based on the pressure curve;

[0012] Based on the pressure parameters of the preset type, the pressing body represented by the pressure signal is determined.

[0013] Optionally, the preset type of pressure parameter includes a first pressure parameter and / or a second pressure parameter; the first pressure parameter is used to represent the rising time of the pressure curve, and the second pressure parameter is used to represent the stabilizing time of the pressure curve;

[0014] The step of determining the pressing body represented by the pressure signal according to the pressure parameters of the preset type includes:

[0015] If the pressure parameter of the preset type meets the first condition, the pressing body is determined to be a human hand, wherein the first condition includes: the first pressure parameter is located in a preset first rise time range, and / or the second pressure parameter is located in a preset first stable time range.

[0016] Optionally, determining the pressing body represented by the pressure signal based on the pressure parameters of a preset type further includes:

The second condition includes: the first pressure parameter is located in a preset second rise time range, and / or the second pressure parameter is located in a preset second stable time range, wherein the second rise time range does not intersect with the first rise time range, and the second stable time range does not intersect with the first stable time range.

[0018] Optionally, the preset type of pressure parameter further includes a third pressure parameter, wherein the third pressure parameter is used to represent the pressure signal corresponding to the first highest point, and the first highest point is the highest point of the pressure curve within a stable duration.

[0019] The first condition also includes: the third pressure parameter is located within a preset range of the first highest point value.

[0020] Optionally, the second condition further includes: the third pressure parameter is located within a preset second highest point range; wherein the minimum value of the second highest point range is greater than the minimum value of the first highest point range.

[0021] Optionally, controlling the opening and closing state of the vehicle's tailgate based on pressing the main body includes:

[0022] In response to the pressing body being a hand, the tailgate of the vehicle is controlled to be in the open state.

[0023] or,

[0024] In response to the pressing body being a water gun, the tailgate of the vehicle is controlled to be in the closed state.

[0025] Optionally, the step of controlling the opening and closing state of the vehicle's tailgate based on pressing the main body further includes:

[0026] If the pressing body is an unknown body, then the opening and closing state of the tailgate of the vehicle is the tailgate closed state. The unknown body indicates that the pressing body is neither a human hand nor a water gun.

[0027] In addition, this application also provides a tailgate control system, including:

[0028] The pressure signal acquisition module is used to acquire the pressure signal applied to the outer surface of the vehicle's tailgate;

[0029] The pressing body determination module is used to determine the pressing body represented by the pressure signal;

[0030] The tailgate control module is used to control the opening and closing state of the vehicle's tailgate based on the pressing body.

[0031] In addition, this application also provides a vehicle including the system described above.

[0032] The above technical solution can acquire pressure signals applied to the outer surface of the vehicle's tailgate, identify the pressing entity based on the pressure signal, and then control the tailgate's opening and closing state according to the pressing entity. This enables precise control of the tailgate's opening and closing state based on different pressing entities, solving the problem of accidental tailgate opening caused by the inability to identify the pressing entity in existing technologies, thereby avoiding property damage and safety risks caused by accidental tailgate opening.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] The specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0040] Although the steps in the flowcharts of this application's embodiments are shown sequentially as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in the figures may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be performed alternately or in turn with other steps or at least a portion of the sub-steps or stages of other steps.

[0041] In the following description, the use of suffixes such as "module" and "device" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module" and "device" can be used interchangeably.

[0042] Although the terms first, second, third, etc., may be used in this document to describe various types of information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another.

[0043] See Figure 1 One embodiment of this application provides a tailgate control method, which can be executed by a data processing device provided in this application embodiment. The data processing device can be implemented in software and / or hardware. The data processing device can be a mobile terminal or a fixed terminal. In this embodiment, the data processing device is preferably a mobile terminal. The mobile terminal can be implemented in various forms. For example, the data processing device described in this application can include mobile terminals such as mobile phones, tablet computers, laptops, handheld computers, and personal digital assistants (PDAs).

[0044] The data processing device can be installed inside the vehicle and is communicatively connected to the vehicle's pressure detection device. The pressure detection device is installed on the vehicle's tailgate. The pressure detection device is used to detect the pressure signal on the outer surface of the tailgate and send it to the data processing device. The data processing device is used to control the opening and closing state of the vehicle's tailgate based on the pressure signal.

[0045] The method provided in this embodiment includes the following steps:

[0046] Acquire the pressure signal applied to the outer surface of the vehicle's tailgate.

[0047] Determine the pressing body represented by the pressure signal.

[0048] The opening and closing status of the vehicle's tailgate is controlled by pressing the main body.

[0049] Optionally, acquiring the pressure signal applied to the outer surface of the vehicle's tailgate may include:

[0050] It receives pressure signals detected and transmitted by pressure sensors, which are real-time pressure signals applied to the outer surface of the vehicle's tailgate.

[0051] Optionally, a pressure sensor can continuously acquire pressure signals applied to the outer surface of the tailgate and send these signals to a data processing device at preset time intervals. The preset time interval is preferably 10 milliseconds. This ensures that the data processing device continuously and automatically controls the opening and closing of the vehicle's tailgate without human intervention, thus improving the user experience.

[0052] Optionally, the pressing body refers to the pressing action subject that applies pressure to the outer surface of the tailgate. The pressing body is different in different application scenarios. For example, when the driver wants to open the tailgate, he will press the outer surface of the tailgate with his hand. At this time, the pressing body is the human hand. In the car wash scenario, the high-pressure water flow generated by the water gun impacts the outer surface of the tailgate. At this time, the pressing body is the water gun.

[0053] Optionally, after receiving pressure signals from the pressure sensor at preset time intervals, the data processing device can determine the corresponding pressing subject based on the currently received pressure signal. The principle of this operation is that different pressing subjects produce different pressure signals. For example, when the pressing subject is a human hand, the muscles of the fingers or palm apply pressure gradually; while when the pressing subject is a water gun, the water flow does not apply pressure gradually but is an instantaneous impact, and the pressure generated by the water flow usually rises instantaneously.

[0054] Optionally, the data processing device can control the opening and closing state of the vehicle's tailgate based on the pressing body. When the pressing body is a qualified body, the tailgate is controlled to be in the open state; when the pressing body is an unqualified body, the tailgate is controlled to be in the closed state. Here, a qualified body is a pressing body that will not cause the tailgate to open accidentally, such as a human hand; an unqualified body is a pressing body that will cause the tailgate to open accidentally, such as a water gun.

[0055] The above technical solution can acquire pressure signals applied to the outer surface of the vehicle's tailgate, identify the pressing entity based on the pressure signal, and then control the tailgate's opening and closing state according to the pressing entity. This enables precise control of the tailgate's opening and closing state based on different pressing entities, solving the problem of accidental tailgate opening caused by the inability to identify the pressing entity in existing technologies, thereby avoiding property damage and safety risks caused by accidental tailgate opening.

[0056] Optionally, the pressing body representing the pressure signal may include:

[0057] The corresponding pressure curve is determined based on the pressure signal.

[0058] Obtain the preset type of pressure parameters based on the pressure curve.

[0059] Based on the preset pressure parameters, determine the pressing body represented by the pressure signal.

[0060] Optionally, the pressure signal can be the pressure ADC value output by the pressure sensor; the pressure ADC value is the digital representation of the pressure signal; the pressure sensor converts the pressure change into a voltage signal, and amplifies the voltage signal to convert it into a pressure ADC value.

[0061] Optionally, the pressure curve can reflect the process of pressure signal changing over time; the horizontal axis of the pressure curve can be time, and the vertical axis can be the pressure ADC value.

[0062] Optionally, determining the corresponding pressure curve based on the pressure signal may include:

[0063] After receiving the pressure signal from the pressure sensor, the data processing device first performs data preprocessing on the pressure signal, and then determines the corresponding pressure curve based on the pressure signal after the data preprocessing.

[0064] Data preprocessing can improve the reliability of pressure signals. The preferred data preprocessing operation is to first perform outlier detection and processing, and then perform data smoothing. Outlier detection and processing can purify the pressure signal, while data smoothing can effectively suppress random interference.

[0065] Different pressing bodies correspond to different pressure curves. Preset pressure parameters can reflect the distinguishing characteristics of different pressure curves. Therefore, the pressing body represented by the pressure signal can be determined based on the preset pressure parameters.

[0066] This application can determine the pressing subject represented by the pressure signal based on the pressure curve, thereby realizing intelligent identification of the pressing subject without manual intervention, which is convenient and fast.

[0067] Optionally, the preset pressure parameters may include a first pressure parameter and / or a second pressure parameter. The first pressure parameter represents the rise time of the pressure curve, and the second pressure parameter represents the stabilization time of the pressure curve.

[0068] Optionally, determining the pressing body representing the pressure signal based on preset pressure parameters may include:

[0069] If the pressure parameters of a preset type meet the first condition, the pressing body is determined to be a hand. The first condition may include: the first pressure parameter is located in a preset first rise time range, and / or the second pressure parameter is located in a preset first stable time range.

[0070] Optionally, the pressure curve can be divided into three stages: an upward stage, a stable stage, and a downward stage. In the upward stage, the pressure ADC value gradually increases over time until it reaches its maximum point; in the stable stage, the pressure ADC value remains at a relatively stable level; and in the downward stage, the pressure ADC value gradually decreases.

[0071] Optionally, the rising duration of the pressure curve refers to the duration corresponding to the rising phase of the pressure curve; the stabilizing duration of the pressure curve refers to the duration corresponding to the stabilizing phase of the pressure curve.

[0072] See Figure 2 and Figure 3 When the pressing device is a hand, the pressure curve rises more slowly during the initial rise due to the gradual application of force. Conversely, when the pressing device is a water gun, the high-pressure water flow is typically an instantaneous impact, resulting in a very rapid rise in the initial rise. Therefore, the rise time of the pressure curve corresponding to hand pressing is relatively shorter. Furthermore, the duration of hand pressing is more stable; high-pressure water flow is typically an instantaneous pulse or a series of short, high-frequency pulses, with an unstable duration. Consequently, the stability time of the pressure curve corresponding to water gun pressing is relatively shorter compared to the stability time of the pressure curve corresponding to hand pressing.

[0073] In summary, the data processing device can determine the pressing body represented by the pressure signal based on the first pressure parameter and / or the second pressure parameter.

[0074] Optionally, when the preset type of pressure parameter includes a first pressure parameter, the first condition may include: the first pressure parameter is located within a preset range of first rise time values.

[0075] Optionally, when the preset type of pressure parameter includes a second pressure parameter, the first condition may include: the second pressure parameter is located within a preset first stable duration value range.

[0076] Optionally, when the preset type of pressure parameters includes a first pressure parameter and a second pressure parameter, the first condition may include: the first pressure parameter is located within a preset first rise time range, and / or the second pressure parameter is located within a preset first stability time range.

[0077] This application can quickly determine whether the pressing body is a human hand based on the first pressure parameter or the second pressure parameter; this application can also determine whether the pressing body is a human hand based on the first pressure parameter and the second pressure parameter. Determining whether the pressing body is a human hand based on two pressure parameters can improve the accuracy of human hand pressing recognition, thereby improving the accuracy of controlling the opening of the tailgate.

[0078] Optionally, a simulation environment can be set up to conduct multiple actual tests, ultimately obtaining the range of values ​​for the first rising duration and the first stable duration. The simulation environment can be one where a hand controls the tailgate opening and closing state while pressing the main body.

[0079] Optionally, the range of values ​​for the first rise duration can be a range of values ​​that are greater than or equal to the first rise duration measurement value and less than or equal to the second rise duration measurement value. The first rise duration measurement value is preferably 0.27s, and the second rise duration measurement value is preferably 0.62s.

[0080] Optionally, the process for determining the first and second rise duration measurements can be as follows: A simulated environment is built to control the tailgate opening and closing state when the pressing body is a human hand. Multiple actual tests are conducted to obtain the first measurement value of 0.21s, the second measurement value of 0.29s, and the third measurement value of 0.32s at the left end of the first rise duration range. The average of the three measurements at the left end is calculated to obtain the first rise duration measurement value of 0.27s. Alternatively, the first measurement value of 0.42s, the second measurement value of 0.67s, and the third measurement value of 0.77s at the right end of the first rise duration range can be obtained. The average of the three measurements at the right end is calculated to be 0.62s, and this average value is determined as the second rise duration measurement value.

[0081] Optionally, the range of values ​​for the first stable duration can be a range of values ​​greater than or equal to the measured value of the first stable duration, and the measured value of the first stable duration is preferably 0.58s.

[0082] Optionally, the process for determining the first stable duration measurement value can be as follows: build a simulated environment that controls the tailgate opening and closing state when the pressing body is a human hand, conduct multiple actual tests, and obtain the first measurement value of 0.45s, the second measurement value of 0.6s, and the third measurement value of 0.7s at the left end of the first stable duration value range. Calculate the average value of the above three measurements as 0.58s, and determine the average value as the first stable duration measurement value.

[0083] This application obtains the value range of various pressure parameters corresponding to human hand pressing by building a simulated environment and conducting multiple actual tests, thereby ensuring the accuracy and usability of the value range of each pressure parameter, improving the accuracy of human hand pressing recognition, and thus improving the accuracy of controlling the opening of the tailgate.

[0084] Optionally, the pressing body representing the pressure signal, determined according to preset pressure parameters, may further include:

[0085] If the pressure parameters of the preset type meet the second condition, the pressing body is determined to be a water gun. The second condition may include: the first pressure parameter is located in the preset second rise time range, and / or the second pressure parameter is located in the preset second stable time range, wherein the second rise time range does not intersect with the first rise time range, and the second stable time range does not intersect with the first stable time range.

[0086] Optionally, a simulation environment can be set up to conduct multiple actual tests, ultimately obtaining the second rising time range and the second stable time range. The simulation environment can be one that controls the tailgate opening and closing state when the pressing element is a water gun.

[0087] Optionally, the range of the second rise duration can be a range smaller than the range of the third rise duration measurement, and the third rise duration measurement is preferably 0.018s.

[0088] Optionally, the process for determining the third rise time measurement value can be as follows: Build a simulated environment that controls the tailgate opening and closing state when the main body is a water gun, conduct multiple actual tests, and obtain the first measurement value of the right end of the second rise time value range as 0.015s, the second measurement value as 0.02s, and the third measurement value as 0.02s. Calculate the average value of the above three measurement values ​​as 0.018s, and determine this average value as the third rise time measurement value.

[0089] Optionally, the range of values ​​for the second stable duration can be a range of values ​​less than or equal to the measured value of the second stable duration, and the measured value of the second stable duration is preferably 0.023s.

[0090] Optionally, the process for determining the second stable duration measurement value can be as follows: Build a simulated environment that controls the tailgate opening and closing state when the main body is a water gun, conduct multiple actual tests, and obtain the first measurement value of the right endpoint of the second stable duration value range as 0.01s, the second measurement value as 0.02s, and the third measurement value as 0.04s. Calculate the average value of the above three measurement values ​​as 0.023s, and determine this average value as the second stable duration measurement value.

[0091] This application obtains the value range of each pressure parameter corresponding to water gun pressing by building a simulated environment and conducting multiple actual tests, thereby ensuring the accuracy and usability of the value range of each pressure parameter, improving the accuracy of water gun pressing recognition, and thus improving the accuracy of controlling the tailgate closing.

[0092] Optionally, the preset type of pressure parameter may also include a third pressure parameter, wherein the third pressure parameter is used to represent the pressure signal corresponding to the first highest point, and the first highest point is the highest point of the pressure curve within a stable duration.

[0093] Optionally, the first condition may also include: the third pressure parameter is located within a preset range of the first highest point value.

[0094] See Figure 2 and Figure 3 Since the pressure generated by pressing with a hand is much smaller than the pressure generated by pressing with a water gun, the pressure ADC value of the first highest point corresponding to the hand pressing is relatively larger than that of the first highest point corresponding to the water gun pressing.

[0095] Optionally, a simulation environment can be set up to conduct multiple actual tests, ultimately obtaining the range of values ​​for the first highest point. The simulation environment can be one where a hand controls the tailgate opening and closing state when pressing the main body.

[0096] Optionally, the range of values ​​for the first highest point can be a range of values ​​greater than or equal to the measured value of the first highest point, and the measured value of the first highest point is the pressure ADC value of the first highest point, preferably 1350.

[0097] Optionally, the process of determining the first highest point measurement value can be as follows: build a simulated environment that controls the tailgate opening and closing state when the pressing body is a human hand, conduct multiple actual tests, and obtain the first measurement value of the left endpoint of the first highest point value range as 1200, the second measurement value as 1350, and the third measurement value as 1500. Calculate the average value of the above three measurement values ​​as 1350, and determine the average value as the first highest point measurement value.

[0098] The preset pressure parameters in this application may also include a third pressure parameter. Therefore, this application can determine whether the pressing body is a human hand based on up to three pressure parameters, which can greatly improve the accuracy of human hand pressing recognition and thus improve the accuracy of controlling the opening of the tailgate.

[0099] Optionally, the second condition may further include: the third pressure parameter is located within a preset second highest point range; wherein the minimum value of the second highest point range is greater than the minimum value of the first highest point range.

[0100] Optionally, a simulation environment can be set up to conduct multiple actual tests, ultimately obtaining the range of values ​​for the second highest point. The simulation environment can be one that controls the tailgate opening and closing state when the main body is a water gun.

[0101] Optionally, the range of values ​​for the second highest point can be a range of values ​​greater than or equal to the measured value of the second highest point. The measured value of the second highest point is the pressure ADC value of the second highest point, and the measured value of the second highest point is preferably 23000.

[0102] Optionally, the process for determining the second highest point measurement value can be as follows: Build a simulated environment that controls the tailgate opening and closing state when the main body is a water gun, conduct multiple actual tests, and obtain the first measurement value of the left endpoint of the first highest point value range as 21000, the second measurement value as 23000, and the third measurement value as 25000. Calculate the average of the above three measurement values ​​as 23000, and determine this average value as the second highest point measurement value.

[0103] The second condition in this application may also include the value range of the third pressure parameter. Therefore, this application can determine whether the pressing body is a water gun based on up to three pressure parameters, which can greatly improve the accuracy of water gun pressing identification and thus improve the accuracy of controlling the tailgate closing.

[0104] Optionally, the opening and closing state of the vehicle's tailgate controlled by pressing the main body may include:

[0105] In response to the pressing of the main body being a human hand, the tailgate of the vehicle is controlled to be in the open state;

[0106] or,

[0107] In response to the pressing of the main body being a water gun, the tailgate of the vehicle is controlled to be in the closed state.

[0108] Optionally, the data processing device is communicatively connected to the vehicle's control device, and the control device is communicatively connected to the tailgate. The control device can be the vehicle's microcontroller unit (MCU). The MCU is the core control unit of the automotive electronic system. The MCU is mainly responsible for converting various input signals of the vehicle into output signals to precisely control various parts of the vehicle. The MCU usually integrates a CPU and memory, and is equipped with a series of input and output ports to connect with various sensors and actuators in the vehicle.

[0109] Optionally, if the data processing device determines that the pressing body is a hand, it sends a request to the control device to control the tailgate to open; after receiving the request, the control device controls the tailgate to open.

[0110] Optionally, if the data processing device determines that the pressing body is a water gun, it sends a request to the control device to close the tailgate; after receiving the request, the control device controls the tailgate to be closed.

[0111] This application controls the tailgate to be open when the pressing object is determined to be a hand, and to be closed when the pressing object is determined to be a water gun. This ensures that the tailgate opens normally when a hand presses it, and also ensures that the tailgate remains closed when the water gun impacts it in a car wash scenario. This allows for accurate control of the tailgate's opening and closing, solving the problem of accidental tailgate opening in car wash scenarios.

[0112] Optionally, the system may further include the following based on the opening and closing state of the vehicle's tailgate controlled by pressing the main body:

[0113] If the pressing entity is an unknown entity, then the tailgate of the vehicle will be closed. An unknown entity indicates that the pressing entity is neither a human hand nor a water gun.

[0114] Optionally, if the data processing device determines that the pressure parameters of the preset type do not meet either the first condition or the second condition, it determines that the pressing body is neither a hand nor a water gun, i.e., the pressing body is an unknown body. At this time, the data processing device sends a request to the control device to close the tailgate; after receiving the request, the control device controls the tailgate's opening and closing state to the tailgate closed state.

[0115] Alternatively, the unknown subject could be extreme weather such as strong winds, the pressure of which could cause the tailgate to open accidentally; the unknown subject could also be a vehicle software malfunction, which could affect the tailgate control logic and cause the tailgate to open accidentally; the unknown subject could also be an accidental impact object such as a falling tree branch, the pressure of which could cause the tailgate to open accidentally.

[0116] When the pressing entity is identified as an unknown entity, this application controls the tailgate to be closed, thus avoiding the problem of the tailgate being accidentally opened due to an unknown entity, and thereby avoiding property damage and safety risks caused by the accidental opening of the tailgate.

[0117] See Figure 4 Another embodiment of this application provides a tailgate control system, including:

[0118] Pressure signal acquisition module 1 is used to acquire the pressure signal applied to the outer surface of the tailgate of the vehicle.

[0119] The pressing body judgment module 2 is used to judge the pressing body represented by the pressure signal.

[0120] Tailgate control module 3 is used to control the opening and closing status of the vehicle's tailgate based on the pressing of the main body.

[0121] In some implementations, the pressing body judgment module 2 can also be used for:

[0122] Determine the corresponding pressure curve based on the pressure signal; obtain the preset type of pressure parameters based on the pressure curve; determine the pressing body represented by the pressure signal based on the preset type of pressure parameters.

[0123] In some implementations, the pressure parameters of a preset type in the pressing body judgment module 2 may include: a first pressure parameter and / or a second pressure parameter; the first pressure parameter is used to represent the rising time of the pressure curve, and the second pressure parameter is used to represent the stabilizing time of the pressure curve.

[0124] In some implementations, the pressing body judgment module 2 can also be used for:

[0125] If the pressure parameters of a preset type meet the first condition, the pressing body is determined to be a hand. The first condition may include: the first pressure parameter is located in a preset first rise time range, and / or the second pressure parameter is located in a preset first stable time range.

[0126] In some implementations, the pressing body judgment module 2 can also be used for:

[0127] If the pressure parameters of the preset type meet the second condition, the pressing body is determined to be a water gun. The second condition may include: the first pressure parameter is located in the preset second rise time range, and / or the second pressure parameter is located in the preset second stable time range, wherein the second rise time range does not intersect with the first rise time range, and the second stable time range does not intersect with the first stable time range.

[0128] In some implementations, the pressure parameters of the preset type in the pressing body judgment module 2 may also include a third pressure parameter, wherein the third pressure parameter is used to represent the pressure signal corresponding to the first highest point, and the first highest point is the highest point of the pressure curve within a stable duration.
