Description

Technical Field

[0001] The present application relates to the field of automation control technology, and in particular to a method, device, vehicle, and electronic equipment for controlling a space isolation device. Background Art

[0002] Currently, many space barrier devices have a one-touch automatic closing function. However, if the space barrier device closes at a fixed speed, a loud noise, called impact noise, will be produced when the device is fully closed. To reduce impact noise, a common method is to reduce the speed of the space barrier device before it is fully closed.

[0003] For example, in the field of passenger cars, the window movement speed is controlled by adjusting the PWM (Pulse Width Modulation) wave duty cycle of the window motor, and the window position is determined by counting the Hall waveform. When the window uses the one-button up function, the window rises to 60±5mm from the top, the PWM wave duty cycle of the window motor will be reduced to reduce the window movement speed, thereby realizing the slow-up function.

[0004] Existing methods for reducing impact noise from space isolation devices maintain a fixed movement speed for a period of time before closing. In real-world scenarios, varying environmental conditions can affect the magnitude of impact noise. Consequently, existing space isolation device control methods are not adaptable to environmental conditions and cannot fully minimize impact noise. Summary of the Invention

Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] In order to solve the technical problem that the existing technology cannot reduce the impact noise of the space isolation device under different environmental conditions, the present application provides a space isolation device control method that can adapt to various environments and reduce the impact noise to the greatest extent.

[0041] Figure 1 A flow chart of a method for controlling a space isolation device provided in an embodiment of the present application. This method can be applied to various scenarios involving space isolation devices, such as vehicles, transmissions, rooms, and the like. This method can be executed by various electronic devices, such as a controller on a vehicle, a smart phone, a laptop computer, a desktop computer, a portable computer, a server, and one or more other electronic devices. After executing this method, the above-mentioned electronic device can directly drive the motor of the space isolation device to control the closing speed of the space isolation device, or it can be remotely connected to the space isolation device controller and, after executing this method, send instructions to the space isolation device controller to control the closing speed of the space isolation device.

[0042] In addition, the execution subject of this method can be hardware or software. When the execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the execution subject is software, the method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitations are given here.

[0043] like Figure 1 As shown, the method specifically includes:

[0044] Step 101 : In response to triggering an automatic closing operation for a space isolation device, determining a current environmental detection value of a target space and obtaining a preset expected impact noise amount.

[0045] In this embodiment, the space isolation device is located at the boundary of the target space. The space isolation device can be a door, window or other device, which can be controlled by the above-mentioned resistance device to perform automatic closing or automatic opening operations. The expected impact noise amount represents the impact noise generated by the space isolation device at the closing moment. The above-mentioned target space can be a space in various scenarios, such as the interior space of a vehicle, the space in a room, the space in a ship, etc. The space isolation device can be automatically closed or opened to complete the connection or isolation between the target space and the outside world. The above-mentioned automatic closing operation for the space isolation device can be triggered by various methods such as buttons, voice, gestures, etc. When the automatic closing operation is triggered, the space isolation device moves according to the preset initial speed.

[0046] The expected impact noise level may be a pre-calibrated upper limit of impact noise, typically in decibels (dB).

[0047] The current environment detection value may be a value detected by various sensors, and different types of sensors may detect different types of current environment detection values. For example, a temperature sensor may be used to collect the current temperature of the target space, or a humidity sensor may be used to collect the current humidity of the target space.

[0048] The impact noise level generated when closing a space barrier is affected not only by the closing speed but also by environmental factors within the target space. For example, at a constant closing speed, the impact noise generated by closing a space barrier varies under different temperatures. Another example is that at a constant closing speed, the impact noise generated by closing a space barrier varies under different humidity conditions.

[0049] Step 102: Determine the environmental impact amount corresponding to the current environmental detection value based on the preset first noise impact relationship information.

[0050] In this embodiment, the environmental impact value indicates the degree of influence of the current environmental detection value on the impact noise, and the first noise impact relationship information indicates the influence relationship between the environmental detection value and the impact noise.

[0051] The first noise impact relationship information may be in the form of a table, a calculation formula, or the like. The electronic device may look up the environmental impact amount corresponding to the current environmental detection value from the table, or calculate the environmental impact amount according to the calculation formula. The environmental impact amount corresponds to the current environmental detection value, i.e., the amount by which the current environmental detection value increases or decreases the impact noise. For example, different temperatures may increase or decrease the impact noise.

[0052] Step 103: Determine the noise difference between the expected impact noise amount and the environmental impact amount.

[0053] In this embodiment, the noise difference is a value obtained by subtracting the environmental impact amount from the expected impact noise amount. The noise difference represents the change in impact noise caused by the moving speed of the space isolation device in the current environment.

[0054] Step 104 : determining a target closing speed control amount corresponding to the noise difference based on the preset second noise impact relationship information.

[0055] In this embodiment, the second noise impact relationship information indicates the impact relationship between closing speed and impact noise. The second noise impact relationship information can be in the form of a table, a calculation formula, or the like. The electronic device can use the table to find the closing speed control value corresponding to the noise difference as the target closing speed control value, or calculate the target closing speed control value using the calculation formula.

[0056] The closing speed control amount is the amount of controlling the movement of the space isolation device. Generally, the closing speed control amount can be the duty cycle of the PWM wave of the drive motor of the space isolation device. The larger the duty cycle, the higher the motor speed and the faster the closing speed.

[0057] Step 105: Determine the closing degree of the space isolation device in real time.

[0058] In this embodiment, the degree of closure of the spatial isolation device can be represented by various physical quantities. For example, when the spatial isolation device is closed or opened by moving vertically or horizontally, the degree of closure can be represented by the width of the gap between the edge of the spatial isolation device and the position where the edge reaches. This width can be determined by counting Hall waveforms to determine the position of the spatial isolation device.

[0059] For another example, when the space isolation device is closed or opened by rotating around a rotation axis, the degree of closing can be represented by the angle of rotation of the space isolation device around the rotation axis. This angle can be determined by the rotation angle of the motor.

[0060] Step 106 : In response to the closing degree reaching a preset degree, controlling the space isolation device to close based on the target closing speed control amount.

[0061] In this embodiment, the preset degree corresponds to the physical quantity of the aforementioned degree of closure. For example, a threshold value for the width of the gap between the edge of the spatial isolation device and the position at which the edge ultimately reaches can be set. This threshold value represents the aforementioned preset degree. When the gap width decreases to this threshold value, the spatial isolation device is controlled to close based on the target closing speed control amount. For another example, a threshold value for the angle between the spatial isolation device before and after full closure can be set. This threshold value represents the aforementioned preset degree. When the angle between the edge of the spatial isolation device and the position at which the edge ultimately reaches decreases to this threshold value, the spatial isolation device is controlled to close based on the target closing speed control amount.

[0062] When the space partitioning device is driven to close based on the target closing speed control amount, the generated impact noise is the same as the expected impact noise amount.

[0063] The spatial isolation device control method provided in the embodiment of the present application determines the current environmental detection value when the spatial isolation device is automatically closed, determines the environmental impact amount corresponding to the current environmental detection value based on the preset first noise impact relationship information, and then determines the noise difference between the expected impact noise amount and the environmental impact amount. Based on the preset second noise impact relationship information, the target closing speed control amount corresponding to the noise difference is determined. Finally, when the closing degree of the spatial isolation device reaches the preset degree, the spatial isolation device is controlled to close based on the target closing speed control amount. The embodiment of the present application uses the environmental detection value as a reference factor for controlling the closing speed of the spatial isolation device when the spatial isolation device is automatically closed, which can minimize the impact of environmental factors on the impact noise, so that the impact noise can be limited to a certain degree under various environmental conditions. In addition, the embodiment of the present application only needs to make functional adjustments at the software level, without the need to change the hardware, resulting in a shorter product development cycle and lower costs.

[0064] In some optional implementations of this embodiment, the first noise impact relationship information includes an environmental noise impact coefficient. The environmental noise impact coefficient is a fixed value (e.g., 0.1), which can be pre-calibrated. For example, the changes in impact noise corresponding to different environmental detection values ​​can be pre-recorded to thereby fit a coefficient representing the relationship between the environmental detection value and the impact noise.

[0065] like Figure 2 As shown, step 102 includes:

[0066] Step 1021 : Based on the first algorithm, the environmental noise influence coefficient and the current environmental detection value are calculated to obtain the noise fluctuation amount corresponding to the current environmental detection value.

[0067] Typically, the environmental noise impact coefficient can be multiplied by the current environmental detection value. The product is the noise fluctuation, that is, the change in impact noise caused by environmental changes. Optionally, a preset offset can be added to the above product to obtain the noise fluctuation.

[0068] Step 1022: Obtain a preset basic noise amount, and sum the basic noise amount and the noise fluctuation amount to obtain an environmental impact amount.

[0069] The base noise level is the impact noise measured under a base environment when the space isolation device is closed at the minimum speed limit. For example, the base noise level is the impact noise measured when the space isolation device is closed at the set minimum operating speed in an environment of 0°C. Another example is the impact noise measured when the space isolation device is closed at the set minimum operating speed in an environment of 0% humidity.

[0070] When the environmental impact variable is fixed, a change in the closing speed will cause a change in the final impact noise, and the relationship between the two can be represented by the second noise impact relationship information.

[0071] This embodiment sets the environmental noise impact coefficient and uses the environmental noise impact coefficient and the current environmental detection value for calculation, thereby pre-calibrating a numerical value that represents the impact of environmental changes on impact noise. This numerical value can be used to quickly calculate the noise fluctuation amount, which helps to improve the efficiency of determining the environmental impact amount.

[0072] In some optional implementations of this embodiment, the current environmental detection value includes a current temperature value, and the environmental noise impact coefficient includes a temperature noise impact coefficient. The current temperature value is a temperature value collected by a temperature sensor located within the target space, and the temperature noise impact coefficient is pre-calibrated and represents the relationship between temperature changes and impact noise changes. For example, the impact noise changes corresponding to different temperature values ​​can be pre-recorded to thereby fit a coefficient representing the relationship between the environmental detection value and the impact noise changes.

[0073] like Figure 3 As shown, step 1021 includes:

[0074] Step 10211: Based on the first algorithm, calculate the temperature noise influence coefficient and the current temperature value to obtain the noise fluctuation amount corresponding to the current temperature value.

[0075] Optionally, you can multiply the temperature noise impact coefficient by the current temperature value. The product is the noise fluctuation corresponding to the current temperature value, that is, the change in impact noise due to temperature changes. For example, a temperature noise impact coefficient of 0.1 means that the impact noise changes by 0.1dB for every 1°C increase in temperature. Therefore, 0.1*Current Temperature Value represents the change in impact noise relative to the current temperature of 0°C.

[0076] Optionally, a preset offset may be added to the above product to obtain the noise fluctuation amount.

[0077] Step 1022 includes:

[0078] Step 10221: Obtain the noise amount measured in advance at a basic temperature when the spatial isolation device is closed at a lower speed limit as the basic noise amount.

[0079] The base temperature can be any temperature, typically 0°C. The lower speed limit is the minimum allowable speed when the space isolation device is closed. The base noise level is the impact noise level when the space isolation device is closed at the minimum speed in a 0°C environment.

[0080] Step 10222: sum the basic noise amount and the noise floating amount to obtain the environmental impact amount.

[0081] When the environmental impact amount obtained in this step is fixed, changes in the closing speed will cause changes in the final impact noise, and the relationship between the two can be represented by the above-mentioned second noise impact relationship information.

[0082] This embodiment sets the temperature noise influence coefficient and uses the temperature noise influence coefficient and the current temperature value for calculation, thereby pre-calibrating a numerical value representing the impact of temperature changes on impact noise. This numerical value can be used to quickly and accurately calculate the impact of temperature changes on impact noise, thereby helping to improve the efficiency and accuracy of controlling impact noise based on temperature factors.

[0083] In some optional implementations of this embodiment, the second noise impact relationship information includes a control variable noise impact coefficient. The control variable noise impact coefficient is a fixed value (e.g., 0.2), which can be pre-calibrated. For example, the change in impulse noise caused by different PWM wave duty cycles of the drive motor can be pre-recorded, thereby fitting a coefficient representing the relationship between the duty cycle and the impulse noise.

[0084] The above step 104 can be performed as follows:

[0085] Based on the second algorithm, the control variable noise influence coefficient and the noise difference are calculated to obtain the target closing speed control variable corresponding to the noise difference.

[0086] Alternatively, the product of the control variable noise impact coefficient and the target closing speed control variable can be used as the noise difference. Accordingly, the noise difference divided by the control variable noise impact coefficient yields the target closing speed control variable corresponding to the noise difference. This noise difference represents the effect of changes in closing speed on impact noise, based on the lower speed limit of the spatial isolation device, after removing the impact of environmental factors on impact noise.

[0087] Optionally, a preset offset may be added to the product of the above-mentioned control quantity noise influence coefficient and the target closing speed control quantity to obtain a noise difference. Accordingly, according to the algorithm, the target closing speed control quantity corresponding to the noise difference may be calculated.

[0088] For example, a control variable noise impact coefficient of 0.2 indicates that, excluding environmental factors, the impact noise of the space isolation device's drive motor increases by 0.2dB for every 1% increase in duty cycle, based on the minimum speed. The noise difference / 0.2 is the target duty cycle, or the target closing speed control variable.

[0089] In conjunction with the example in the above embodiment, assuming the expected impact noise level is A, the base noise level corresponding to a 0°C environment is B, the ambient temperature is C, the temperature noise influence coefficient is 0.1, the drive motor PWM wave duty cycle is D, and the control variable noise influence coefficient is 0.2, the following relationship can be obtained: A = B + C * 0.1 + D * 0.2. Based on this relationship, B + C * 0.1 is the noise difference, and the duty cycle D can be calculated.

[0090] In this embodiment, by setting the control quantity noise influence coefficient, after obtaining the noise difference, the control quantity noise influence coefficient can be used to directly calculate the target closing speed control quantity, thereby more accurately and efficiently controlling the closing speed of the space isolation device to control the impact noise amount.

[0091] In some optional implementations of this embodiment, such as Figure 4 As shown, step 105 includes:

[0092] Step 1051 : Determine in real time the distance between the edge of the space isolation device and the target stop position.

[0093] The target stop position is the position of the edge when the space isolation device is closed. Specifically, when the space isolation device is closed or opened by moving up and down or left and right, the distance can be determined by counting the Hall effect waveform to determine the position of the space isolation device.

[0094] Step 1052: Determine the degree of closure of the space isolation device based on the distance.

[0095] Specifically, the distance can represent the degree of closure of the space isolation device. The smaller the distance, the higher the degree of closure of the space isolation device. Furthermore, a distance threshold can be set, which represents the preset degree in step 106. That is, when the distance is less than or equal to the distance threshold, the space isolation device is controlled to close according to the target closing speed control amount.

[0096] This embodiment determines the distance between the edge of the space isolation device and the target stop position, and determines whether to control the space isolation device to close at the target closing speed control amount based on the distance. This can more specifically set the timing for adjusting the closing speed and improve scene adaptability.

Specifically, the device comprises: an acquisition module 501 for determining a current environmental detection value of a target space and obtaining a preset expected impact noise amount in response to triggering an automatic closing operation for the space isolation device, wherein the space isolation device is located at the boundary of the target space, and the expected impact noise amount represents the impact noise generated by the space isolation device at the time of closing; a first determination module 502 for determining an environmental impact amount corresponding to the current environmental detection value based on preset first noise impact relationship information, wherein the environmental impact amount represents the degree of influence of the current environmental detection value on the impact noise, and the first noise impact relationship information represents the influence relationship between the environmental detection value and the impact noise; a second determination module 503 for determining a noise difference between the expected impact noise amount and the environmental impact amount; a third determination module 504 for determining a target closing speed control amount corresponding to the noise difference based on preset second noise impact relationship information, wherein the second noise impact relationship information represents the influence relationship between the closing speed and the impact noise; a fourth determination module 505 for determining the degree of closing of the space isolation device in real time; and a control module 506 for controlling the space isolation device to close based on the target closing speed control amount in response to the degree of closing reaching a preset degree.

[0105] Figure 6 This is a schematic diagram of the structure of a vehicle 600 provided in an embodiment of the present application. Specifically, it includes a window controller 601, an environmental detection sensor 602, power windows 603, and a window drive motor 604. The window controller 601 is connected to the environmental detection sensor 602 and the window drive motor 604, which drives the power windows 603 to close or open.

[0106] The environment detection sensor 602 is used to detect the current environment detection value inside the vehicle.

[0107] The window controller 601 is used to execute the space isolation device control method described in any of the above embodiments based on the current environmental detection value, generate a target closing speed control amount, and send the target closing speed control amount to the window drive motor 604.

[0108] The window drive motor 604 is used to drive the power window 603 to close based on the target closing speed control amount.

[0109] Figure 7 A timing diagram of the various parts of the vehicle provided in an embodiment of the present application.

[0110] like Figure 7As shown, in step 701, the environment detection sensor detects the current environment detection value of the vehicle interior space and sends the current environment detection value to the window controller.

[0111] The vehicle interior space is the target space described in the space isolation device control method. The environment detection sensor may include various types of sensors such as a temperature sensor and a humidity sensor.

[0112] In step 702 , the window controller obtains a preset expected impact noise amount in response to triggering an automatic closing operation for the power window.

[0113] The electric window is the space separating device described in the above-mentioned vehicle interior space control method. The expected impact noise amount represents the impact noise generated when the electric window is closed.

[0114] In step 703 , the window controller determines an environmental impact amount corresponding to the current environmental detection value based on the preset first noise impact relationship information.

[0115] The environmental impact value indicates the degree of influence of the current environmental detection value on the impact noise, and the first noise impact relationship information indicates the influence relationship between the environmental detection value and the impact noise.

[0116] In step 704 , the window controller determines the noise difference between the expected impact noise level and the environmental impact level.

[0117] In step 705 , the window controller determines a target closing speed control amount corresponding to the noise difference based on the preset second noise impact relationship information.

[0118] The second noise influence relationship information indicates the influence relationship between the closing speed and the impact noise.

[0119] In step 706 , the window controller determines the degree of closure of the power windows in real time.

[0120] In step 707 , in response to the closing degree reaching a preset degree, the window controller sends a target closing speed control amount to the window driving motor.

[0121] The above steps 702 to 707 are basically the same as steps 101 to 106 and will not be repeated here.

[0122] In step 708 , the window drive motor drives the power window to close based on the target closing speed control amount.

[0123] Usually, the electric window is closed by rising. When it rises to a certain height, that is, corresponding to a preset closing degree, the rising speed of the electric window is changed to adapt the impact noise when closing to different environments.

[0124] The space isolation device provided in the embodiment of the present application controls the vehicle by determining the current environmental detection value when the electric window is automatically closed, determining the environmental impact amount corresponding to the current environmental detection value based on the preset first noise impact relationship information, then determining the noise difference between the expected impact noise amount and the environmental impact amount, and determining the target closing speed control amount corresponding to the noise difference based on the preset second noise impact relationship information. Finally, when the closing degree of the electric window reaches the preset degree, the window drive motor is controlled to drive the window to close at the target closing speed control amount. The embodiment of the present application uses the environmental detection value as a reference factor for controlling the closing speed of the space isolation device when the electric window is automatically closed, which can minimize the impact of environmental factors on the impact noise, so that the impact noise can be limited to a certain degree under various environmental conditions. In addition, the embodiment of the present application only needs to make functional adjustments at the software level, without the need to change the hardware, resulting in a shorter product development cycle and lower costs.
