Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to a method, device, equipment and storage medium for detecting the opening and closing status of a vehicle window. Background Art

[0002] In the context of the trend towards connected cars, models equipped with one-touch window lifting can read window position signals through the ECU and display the window opening and closing status in real time through a mobile phone app. When the window is not closed, customers will be reminded through the app or text message notification to prevent theft or property loss caused by rain.

[0003] The industry lacks a standard method for setting the critical value for glass opening and closing. Typically, the critical value is set to the upper soft stop position, with position determination performed using a single parameter. 0.3 seconds after the motor is powered off at any glass position, the window ECU reads the window position information (Hall or ripple pulse count) and compares it with the set critical value for opening and closing. The comparison result is sent via a LIN signal, and the app displays and alerts the customer to the window status. However, a problem with this approach is that when the glass reaches the top and reverses, after the motor triggers the soft stop and powers off, the rubber strip reverses slightly due to the reaction force. The window glass has actually reached the top and closed, but the app displays a reminder to the customer that the window is not closed, greatly reducing the user experience.

[0052] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] Reference Figure 1 , Figure 1This is a structural diagram of a vehicle window opening and closing status detection device in the hardware operating environment involved in an embodiment of the present invention.

[0054] like Figure 1 As shown, the vehicle window opening and closing state detection device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (RAM) memory, or a stable non-volatile memory (NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0055] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the window opening and closing state detection device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0056] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a window opening and closing status detection program.

[0057] exist Figure 1 In the vehicle window opening and closing status detection device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the vehicle window opening and closing status detection device of the present invention can be set in the vehicle window opening and closing status detection device, and the vehicle window opening and closing status detection device calls the vehicle window opening and closing status detection program stored in the memory 1005 through the processor 1001, and executes the vehicle window opening and closing status detection method provided by the embodiment of the present invention.

[0058] The embodiment of the present invention provides a method for detecting the opening and closing state of a vehicle window. Figure 2 , Figure 2 This is a flow chart of a first embodiment of a method for detecting the opening and closing status of a vehicle window according to the present invention.

[0059] In this embodiment, the window opening and closing state detection method includes the following steps:

[0060] Step S10: determining the working condition corresponding to the entire movement process of the vehicle window glass from the start of movement to the stop of movement.

[0061] In this embodiment, the executing entity of this embodiment may be the vehicle window opening and closing status detection device, which has functions such as data processing, data communication and program running. The vehicle window opening and closing status detection device may be the electronic control unit (ECU) (or controller) of the vehicle window, or may be a device with the same or similar functions. This embodiment does not impose any restrictions on this, and the vehicle window opening and closing status detection device is used as an example for explanation.

[0062] It should be noted that there is no standard method for setting the glass opening and closing threshold in the current industry. The glass opening and closing threshold is usually set to the upper soft stop position, and the position is determined by a single parameter. 0.3s after the motor is powered off at any position, the window ECU reads the window position information (Hall or ripple pulse number) and compares it with the set opening and closing threshold. The comparison result is sent via the LIN signal and displayed and notified to the customer through the APP. Figure 3 As shown, a single parameter is used as the signal for determining the glass position opening and closing threshold, and the opening and closing threshold signal equals the soft stop position signal. However, a problem with this approach is that when the glass reaches the top and reverses, after the motor triggers the soft stop and is powered off, the rubber strip reacts and reverses. However, the window glass has actually reached the top and closed, yet the app displays a warning that the window is not closed. For example, in extreme conditions, when the top reversal amount exceeds the opening and closing threshold, a false warning may occur. For example, in low-temperature conditions, the top reversal position of a vehicle is 14 qT, which is greater than the opening and closing threshold of 11 qT. At 14 qT, the window glass has actually reached the top and closed, but because it exceeds the opening and closing threshold of 11 qT, the user will be mistakenly reminded that the window is not closed.

[0063] In order to solve the above problems, in this embodiment, dual parameters corresponding to different working conditions are adopted as the glass position opening and closing critical value judgment signal, that is, the opening and closing critical values ​​under different working conditions are determined by dual parameters to avoid false reminders, and the opening and closing critical signal may not be equal to the soft stop position signal.

[0064] In this embodiment, Figure 4 The overall process of this embodiment is described as follows. Figure 4After the lifter motor is powered on, the window glass begins to move up and down. During the movement of the glass, it is monitored in real time whether the upper soft stop signal is triggered (the upper soft stop signal is triggered by the glass position signal + the rising direction speed signal). If the upper soft stop signal is triggered, it can be determined that the corresponding working condition is the top-up reversal working condition. Otherwise, if it is not triggered, it can be determined that the corresponding working condition is the non-top-up reversal working condition. Figure 4 The non-top-to-top reversal condition shown in the figure is the condition where the glass has not risen to the top, and the top-to-top reversal condition is the condition where the glass has risen to the top and reversed due to the reaction force of the rubber strip. The non-top-to-top reversal condition corresponds to the watertightness critical value, and the top-to-top reversal condition corresponds to the opening and closing critical value. Since the non-top-to-top reversal condition is the condition where the glass has not risen to the top, there may be a situation where the car window is not closed and leaks due to rain. Therefore, in this embodiment, for this reason, the watertightness critical value range can be set to 11QT~14QT, and in an optional embodiment, the watertightness critical value can be set to 11QT. In the top-to-top reversal condition, the glass rises to the top, so usually there will be no rain leakage. However, considering that the glass will reverse due to the reaction force of the rubber strip after reaching the top, in order to avoid false alarms, the opening and closing critical value range can be set to 15QT~26QT in this embodiment, and in an optional embodiment, the opening and closing critical value can be set to 20QT. After determining the critical values ​​for different operating conditions, when the window stops moving, the position of the window is compared with the corresponding critical value to determine whether the window is closed. Using different critical values ​​for different operating conditions ensures that the window can be closed in practice without leaking in the rain, while also ensuring that even after the window is closed, the user will not be falsely notified that it is not closed, thereby improving the user experience.

[0065] In a specific implementation, after the lifter motor is powered on, the window glass will start to move up and down. In this embodiment, the focus is on whether the window is actually closed and whether a false reminder of not closing will be sent to the user after it is actually closed. Therefore, when the window glass starts to move up, the window glass will be monitored in this embodiment until the window glass stops moving. After the window glass stops moving, the working conditions corresponding to the entire rising to stopping process are determined.

[0066] In an optional embodiment, the window glass can be monitored for triggering of an upper soft stop signal during the process from start to stop, and the corresponding operating condition for the process from start to stop can be determined based on the triggering result. If the upper soft stop signal is triggered, the operating condition is determined to be a top-end reversal condition; if the upper soft stop signal is not triggered, the operating condition is determined to be a non-top-end reversal condition. Alternatively, the operating condition corresponding to the entire process from start to stop of the window glass can be determined using other methods, which are not limited in this embodiment.

[0067] Step S20: determining a target critical value according to the working condition.

[0068] In this embodiment, after determining the operating conditions corresponding to the entire movement process of the vehicle window glass from the start of movement to the stop of movement, different threshold values ​​are set for different operating conditions. Based on the corresponding relationship between the operating conditions and the threshold values, a target threshold value can be obtained. For example, the threshold value corresponding to the non-top-down reversal operating condition is 11 QT, while the threshold value corresponding to the top-down reversal operating condition is 20 QT. The threshold values ​​corresponding to different operating conditions can also be adjusted accordingly based on actual needs, and this embodiment is not limited to this.

[0069] Step S30: obtaining the position information of the glass when it stops moving.

[0070] It should be understood that this embodiment determines whether a window is closed. The window's open or closed state is related to the position of the glass. Therefore, after determining the critical value, this embodiment further requires obtaining the position information when the glass stops moving. This position information can include the number of Hall or ripple pulses, such as 5QT or 10QT. A smaller QT indicates a smaller gap between the window glass and the top. A 5QT indicates a more tightly closed window than a 10QT.

[0071] Step S40: determining the open / closed state of the vehicle window according to the position information and the target critical value.

[0072] In a specific implementation, after determining the position information, the position information of the glass is compared with the target critical value to determine the open or closed state of the window.

[0073] In an optional embodiment, the number of motor pulses corresponding to the position information can be obtained, and then the number of motor pulses can be compared with the target critical value. Based on the comparison result, the open or closed state of the window at this time can be determined, as shown in Table 1.

[0074] Table 1:

[0075]

[0076] As shown in Table 1, assuming the motor pulse count is 5 QT based on the position information, it can be determined that the motor pulse count is within the range of 0 to 10 QT, indicating that the window is fully closed. Furthermore, assuming the motor pulse count is 950 QT, it can be determined that the motor pulse count is within the range of 940 to 1112 QT, indicating that the window is fully open. Table 1 is provided for illustrative purposes only, and the threshold values ​​set in Table 1 can be adjusted based on actual needs, which is not a limitation in this embodiment.

[0077] This embodiment determines the working condition corresponding to the entire movement process of the vehicle window glass from the start of movement to the stop of movement; determines the target critical value based on the working condition; obtains the position information of the glass when it stops moving; and determines the open and closed state of the vehicle window based on the position information and the target critical value. Different critical values ​​are adopted for different working conditions corresponding to the vehicle window glass. This can ensure that when the vehicle window is not closed, it can accurately remind the user to avoid rain and water leakage. At the same time, it can ensure that after the vehicle window is closed, it will not send a false reminder to the user that it is not closed, thereby improving the user experience.

[0078] refer to Figure 5 , Figure 5 1 is a flow chart of a second embodiment of a method for detecting the opening and closing status of a vehicle window according to the present invention.

[0079] Based on the first embodiment, in the window opening and closing state detection method of this embodiment, step S20 specifically includes:

[0080] Step S201: using a first critical value corresponding to the non-top-reversal working condition as a target critical value; or using a second critical value corresponding to the top-reversal working condition as a target critical value.

[0081] In this embodiment, the non-top-reversal operating condition is a condition in which the glass has not risen to the top, and the top-reversal operating condition is a condition in which the glass has risen to the top and slightly reversed due to the OFF power to the lifter motor and the reaction force of the rubber strip. The target critical value set for the non-top-reversal operating condition for the glass not rising to the top is required to ensure that the user is promptly reminded when the window is not closed to prevent rain leakage or property theft, while the target critical value set for the top-reversal operating condition is required to ensure that after the window is actually closed, there will be no false reminder that the window is not closed. Specifically, when the operating condition is the non-top-reversal operating condition, the target critical value is the first critical value corresponding to the non-top-reversal operating condition, and when the operating condition is the top-reversal operating condition, the target critical value is the second critical value corresponding to the non-top-reversal operating condition. Due to the above different situations, in this embodiment, the first critical value is less than the second critical value.

[0082] Furthermore, the first critical value and the second critical value can be obtained by preset calibration values ​​and historical test parameters of the corresponding working conditions under different test environments. The process of determining the first critical value and the second critical value can be divided into the following steps: Step 1 is to establish the relationship between the number of motor pulses and the glass travel, and the corresponding relationship is Among them, L is the glass stroke, P is the number of motor pulses, N is the number of motor magnets, I is the motor subtraction ratio, and R is the radius of the lifter winding wheel. Step 2 is to measure the glass rise through the motor calibration experiment, for example Figure 4The rise amount b shown in is b = 2.0 + 1.2 + 0.28 = 3.48 mm, where 2.0 is the LIP from contact to compression, 1.2 is the guide groove compression deformation, and 0.28 is the glass offset stroke. Step three is to define the soft stop position. In order to reduce the impact sound of the glass hitting the top, the one-button lifting motor usually has a soft stop function. The soft stop position is usually set before the LIP is fully compressed, that is, L2 = 1.2 + 0.28 = 1.48 ± 0.3 mm. The calculation is b=7.07±1.43QT, and the soft stop position is ≥8.5QT. Considering the inertia of 1-4QT, as well as the guide groove tolerance, watertightness and door closing sound performance, the actual soft stop position of the vehicle model can be defined as 11QT. Step four is to define the upper limit range of the opening and closing critical value. Through the guide groove insertion force experiment, it can be obtained that the position of the glass inserted into the guide groove outside the LIP is 5.5mm from the top dead center, which is 26.27QT. Considering the watertight performance, it is necessary to ensure that the critical value is ≤26QT. In this position range, the glass is not actually closed to the top, but the customer can no longer judge whether the window is closed to the top by observing from outside the car. Step five is to obtain the return amount d, inertia c and glass stop position under different environmental conditions. Through actual vehicle or door assembly testing, the return amount d, inertia c and glass stop position under different environments can be obtained, such as Figure 6 and Figure 7 As shown, the glass stop position can be read directly from historical test parameters by the ECU.

[0083] Table 2:

[0084]

[0085]

[0086] Furthermore, in order to ensure watertightness under non-top-up reversal conditions, the bottom LIP must be in a theoretical compression state, that is, L1 < rise b = 3.48 ± 0.8 mm = 16.6 ± 2.4 QT. 0.8 mm is the LIP tolerance range of the guide groove section, and according to the formula The pulse number P is less than 14.2QT. According to the ECU's technical requirements for pulse signals, the integer is ≤14QT. Since 10QT is the soft stop trigger limit, 11QT≤watertight critical value≤14QT. Considering the software architecture cost, the watertight critical value is equal to the soft stop position, that is, =11QT, which is also the first critical value in this embodiment. Among them, the rise amount b, that is, the historical rise amount, can be directly obtained from historical test parameters. The first reference critical value in this embodiment can be the above-mentioned 14QT, and the upper soft stop position can be 11QT, thus obtaining a first reference critical value range of 11QT to 14QT. The first critical value is then further defined based on this range, for example, the first critical value is defined as 11QT based on the software architecture cost.

[0087] Under the top reversal condition, in order to ensure that there is no false reminder when the glass is closed to the top, it is necessary to meet the opening and closing critical value > glass stop position = upper soft stop - inertia + return amount. The maximum motor position under low temperature conditions is 14QT. The opening and closing critical value ≥ 15QT can be calculated. According to step 4, it is necessary to meet the following: 15QT≤opening and closing critical value≤26QT. Taking into account the system tolerance and performance balance, the opening and closing critical value is finally defined as 20QT, which is the second critical value in this embodiment. Among them, the historical inertia, historical return amount and historical glass stop position can be directly obtained from the historical test parameters. The second reference critical value in this embodiment can be the above-mentioned 15QT, and the opening and closing critical value can be the above-mentioned 26QT, thereby obtaining the second reference critical value range of 15QT~26QT, and then further define the second critical value based on this range. For example, the second critical value is defined as 20QT based on the system tolerance and performance balance.

[0088] This embodiment aims at different working conditions corresponding to the vehicle window glass, and sets more reasonable critical values ​​based on the above-mentioned settings, which can not only ensure that the vehicle windows can be closed in practice without rain leakage, but also ensure that after the vehicle windows are closed, no false reminder of not closing the windows will be sent to the user, thereby improving the user experience.

[0089] In addition, an embodiment of the present invention further provides a storage medium storing a window opening and closing status detection program. When the window opening and closing status detection program is executed by a processor, the steps of the window opening and closing status detection method described above are implemented.

[0090] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0091] Reference Figure 8 , Figure 8 This is a structural block diagram of the first embodiment of the vehicle window opening and closing state detection device of the present invention.

[0092] like Figure 8 As shown, the window opening and closing state detection device proposed in the embodiment of the present invention includes:

[0093] The monitoring module 10 is used to determine the working conditions corresponding to the entire movement process of the vehicle window glass from the start of movement to the stop of movement.

[0096] The recognition module 40 is configured to determine the open or closed state of the vehicle window according to the position information and the target critical value.

[0097] This embodiment determines the working condition corresponding to the entire movement process of the vehicle window glass from the start of movement to the stop of movement; determines the target critical value based on the working condition; obtains the position information of the glass when it stops moving; and determines the open and closed state of the vehicle window based on the position information and the target critical value. Different critical values ​​are adopted for different working conditions corresponding to the vehicle window glass. This can ensure that when the vehicle window is not closed, it can accurately remind the user to avoid rain and water leakage. At the same time, it can ensure that after the vehicle window is closed, it will not send a false reminder to the user that it is not closed, thereby improving the user experience.

[0098] In one embodiment, the operating conditions include a non-top-up reversal operating condition and a top-up reversal operating condition. The non-top-up reversal operating condition refers to other rising and falling operating conditions where the glass has not risen to the top. The top-up reversal operating condition refers to a condition where the glass rises to the top and the soft stop function motor is powered off, causing the glass to reverse under the reaction force of the rubber strip.

[0099] The calling module 20 is further configured to use a first critical value corresponding to the non-top-reversal operating condition as a target critical value; or, use a second critical value corresponding to the top-reversal operating condition as a target critical value; wherein the first critical value is smaller than the second critical value.

[0100] In one embodiment, the first critical value or the second critical value is obtained by a preset calibration value and historical test parameters of the corresponding working condition under different test environments.

[0101] In one embodiment, the preset calibration value includes: an upper soft stop position; the window opening and closing state detection device further includes: a calibration module;

[0102] The calibration module is used to extract a historical rise from the historical test parameters when the working condition is a non-top reversal condition; determine a first reference critical value based on the historical rise, the first reference critical value being a critical value that satisfies the bottom sealing strip in a theoretical compression state; determine a first reference critical value range based on the upper soft stop position and the first reference critical value, and define a first critical value based on the first reference critical value range.

[0103] In one embodiment, the preset calibration values ​​include: an opening and closing critical value and an upper soft stop position;

[0104] The calibration module is further used to extract historical inertia and historical return from the historical test parameters when the operating condition is a top reversal condition; determine a second reference critical value based on the historical inertia, the historical return, and the upper soft stop position; determine a second reference critical value range based on the second reference critical value and the opening and closing critical value, and define a second critical value based on the second reference critical value range.

[0105] In one embodiment, the calibration module is further configured to obtain temperature and voltage under different test environments; and query historical test parameters from a historical test table according to the temperature and voltage.

[0106] In one embodiment, the identification module 40 is further configured to determine the number of motor pulses corresponding to the position information; compare the number of motor pulses with the target critical value; and determine the open or closed state of the vehicle window based on the comparison result.
