It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an opening and closing member control apparatus in a hardware operating environment according to an embodiment of the present invention.
As shown in fig. 1, the opening and closing member control apparatus 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. Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may include a Display screen (Display), an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a Wireless interface (e.g., a Wireless-Fidelity (Wi-Fi) interface). The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the opening and closing member control apparatus, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a kind of storage medium, may include therein an operating system, a network communication module, a user interface module, and an opening and closing member control program.
In the opening-closing member control apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the opening and closing member control apparatus of the present invention may be provided in the opening and closing member control apparatus which calls the opening and closing member control program stored in the memory 1005 through the processor 1001 and executes the opening and closing member control method provided by the embodiment of the present invention.
An embodiment of the present invention provides a method for controlling an opening/closing member, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the method for controlling an opening/closing member according to the present invention.
In this embodiment, the opening/closing member control method includes the steps of:
step S10: and acquiring the working voltage of the driving mechanism corresponding to the opening and closing member in the movement process of the opening and closing member.
In this embodiment, the execution main body of this embodiment may be the opening and closing member control apparatus having functions of data processing, data communication, program execution, and the like, and the opening and closing member control apparatus may be a controller inside an air conditioner. Of course, other devices with similar functions may be used, and the present embodiment is not limited thereto. For convenience of explanation, the present embodiment will be described taking an opening and closing member control device as an example.
It should be noted that, during the opening or closing movement of the electric opening/closing device of the vehicle, the voltage of the battery power supply is rapidly reduced at the moment of starting the engine or the high-power electric device, and the voltage of the opening/closing device driving mechanism is also rapidly reduced, which causes the reduction of the opening/closing speed. The anti-pinch function of the electric opening and closing object is that the normal movement of the opening and closing element is blocked by the external object or personnel, so that the opening and closing speed is reduced. These two different scenarios are prone to false reversals or false movements of the motorized shutter. For the situation, taking an electric vehicle as an example, the current adopted mode is that when the voltage of a power supply changes rapidly, the voltage drops to a certain amplitude V1, and the opening and closing speed drops; if the voltage continuously exceeds a certain time delta t1, the electric vehicle door pauses to move, so that inconvenience, displeasure or scaring of customers caused by mistaken reversal of the vehicle door is avoided, and the previous electric motion is continued after the voltage is restored to V1'.
It should be emphasized that the currently adopted method requires the voltage to drop below a certain voltage to perform the judgment of the false anti-pinch and thus the control of the false anti-pinch, for example, as shown in fig. 3, the currently adopted judgment method requires the voltage to drop below 9V to perform the judgment, and if the starting voltage does not reach below 9V, the judgment is not performed. Further, the current method may further detect whether the duration after the voltage drops to a certain value satisfies the condition, as shown in fig. 4, if the voltage rises back to above 9V at time T2, it may be determined that no erroneous anti-pinch occurs, but from the view of the waveform diagram, the voltage value is also relatively low, the driving speed is low, which may also result in erroneous anti-pinch, and the movement of the vehicle door in which the erroneous anti-pinch occurs may not be controlled according to the current scheme.
In order to solve the above technical problem, as shown in fig. 3 and fig. 4, in this embodiment, only the slope of the descending section is focused, and it can be determined that the voltage has a sudden drop, so as to stop the motion of the tail gate to avoid the mistaken anti-pinch, and effectively cope with this situation.
In the present embodiment, the opening/closing member is an electrically operated opening/closing member, and the opening/closing member may be a member such as an electrically operated side door or an electrically operated tailgate, taking a vehicle as an example.
In specific implementation, the sudden drop of voltage can make the anti-pinch of system take place the reversal, electric door is in the motion process of switching, vehicle power supply voltage changes and leads to its motion that produces wrong direction, for example open in the door closing process is reverse suddenly, to the situation that both is unusual danger to lateral barrier or front and back's passenger/the car of coming, again like electric back door or suitcase in the motion process of switching, the driver starts vehicle or high-power electrical apparatus in the car, control logic disorder leads to the back door mistake reversal to cause the injury, in this embodiment in order to prevent the emergence of this reversal condition, need carry out real-time supervision to the operating voltage of the actuating mechanism that the component corresponds of opening and close.
Step S20: and when the working voltage is detected to be reduced, recording the voltage change rate of the working voltage within a preset time period.
In a specific implementation, the method adopted in this embodiment is to calculate a voltage change rate of the operating voltage, that is, when the operating voltage of the driving mechanism decreases, the operating voltage of the driving mechanism is recorded from the time when the operating voltage decreases, and the voltage change rate of the operating voltage is recorded for a period of time, that is, for a preset period of time. The preset time period may be a minimum value under each working condition that the door is erroneously reversed and is measured during development, and may be set to other time periods according to actual requirements, which is not limited in this embodiment. For example, Δ T shown in fig. 5 is preset time period, the working voltage of the driving mechanism in normal operation is V0, the time period corresponding to the working voltage reduction stage is Δ T, and what is recorded in this embodiment is the voltage change rate in the time period. Specifically, in this embodiment, the voltage change rate may be calculated according to the voltage drop amount and the preset time period, and the specific calculation manner in this embodiment is not limited thereto, and may be selected according to an actual situation.
Step S30: and when the voltage change rate meets a preset condition, controlling the opening and closing member to stop moving through the driving mechanism.
In this embodiment, after obtaining the voltage change rate, it is determined whether the voltage change rate satisfies a predetermined condition, and if the voltage change rate satisfies the predetermined condition, it indicates that the opening/closing member may be erroneously prevented from being jammed due to insufficient driving force caused by voltage reduction, in which case, the opening/closing member is controlled to stop moving.
In the embodiment, the working voltage of the driving mechanism corresponding to the opening and closing component is obtained in the process of the movement of the opening and closing component; when the working voltage is detected to be reduced, recording the voltage change rate of the working voltage within a preset time period; when the voltage change rate satisfies the preset condition, through actuating mechanism control the switching component stop motion, through the voltage change rate of paying close attention to the decline section, satisfy the preset condition at the voltage change rate and can judge that the voltage has the dip to stop the tail-gate motion and avoid the mistake to prevent pressing from both sides, can solve the problem that electronic shutter normally does in mains voltage dip reliably, make the motion of electronic switching piece accord with the expectation.
Referring to fig. 6, fig. 6 is a flowchart illustrating a method for controlling an opening/closing member according to a second embodiment of the present invention.
Based on the first embodiment, in the opening/closing member control method according to the present embodiment, the step S20 specifically includes:
step S201: and taking the moment when the working voltage is reduced as a reference, and acquiring N voltage sampling points in a preset time period from the voltage change process curve.
In specific implementation, the voltage change rate in this embodiment is also the slope of the voltage sampling points on the voltage change process curve, the voltage change process curve is shown in fig. 7, the number of the voltage sampling points shown in fig. 7 is 4, that is, 4 voltage sampling points in the preset time period are obtained in this embodiment, and V1, V2, V3, and V4 shown in fig. 7 are all voltage sampling points.
Step S202: and calculating the slopes of the N-1 voltage sampling points corresponding to the N voltage sampling points.
In a specific implementation, the slopes of the voltage sampling points corresponding to the N voltage sampling points are N-1, for example, the slopes of the voltage sampling points corresponding to the 4 voltage sampling points, i.e., V1, V2, V3 and V4 in fig. 7, are K1, K2 and K3.
Further, when calculating the slope of the voltage sampling points, it is necessary to first obtain the voltages corresponding to the voltage sampling points, i.e., the voltages V1, V2, V3, and V4 corresponding to 4 voltage sampling points in fig. 7. In this embodiment, the voltage sampling points are obtained according to a preset voltage sampling period, for example, the preset voltage sampling period is Cd, and the preset time period is Δ T, the number of the voltage sampling points is Nc = round (Δ T/Cd-1), a downward rounding mode is adopted, the interval time between each sampling point is the preset voltage sampling period, and the slope of the voltage sampling point can be calculated according to the voltage corresponding to each voltage sampling point and the preset voltage sampling period, for example, the slope K1= (V1-V2)/Cd between V1 and V2, the slope K2= (V2-V3)/Cd between V2 and V3, and the slope K3= (V3-V4)/Cd between V3 and V4. Through the above manner, the slope of the N-1 voltage sampling points corresponding to the N voltage sampling points can be calculated, wherein the preset voltage sampling period can be correspondingly set according to actual requirements, which is not limited in this embodiment, and the voltage corresponding to each voltage sampling point can be directly read from the voltage change process curve.
Further, in an actual process, a situation that voltage is accidentally reduced exists in a driving mechanism corresponding to the opening and closing member, but the duration of the process is very short, and the current judgment mode can consider that the opening and closing mechanism triggers the mistaken anti-pinch mechanism, so that the opening and closing mechanism can be controlled to stop moving, but in fact, the situation is considered that the mistaken anti-pinch mechanism triggers the mistaken anti-pinch mechanism unreasonably, in order to avoid the situation, in the embodiment, the minimum sampling number of the voltage sampling points can be calculated according to a preset time period and a preset voltage sampling period, if the voltage sampling points appearing in a period of time are smaller than the minimum sampling number, for example, as shown in fig. 8, the accidental reduction of the voltage cannot meet continuous slope judgment of multiple points, the number of the voltage sampling points actually acquired according to the preset voltage sampling period is smaller than the minimum sampling number calculated based on a theory, and the situation can be avoided by the mode.
In the embodiment, by taking the time when the working voltage decreases as a reference, N voltage sampling points within a preset time period are obtained from the voltage change process curve to obtain the voltage corresponding to each voltage sampling point; calculating the slopes of N-1 voltage sampling points according to the voltages corresponding to the voltage sampling points and the preset voltage sampling period, accurately calculating the slopes of the voltage sampling points, and calculating the minimum sampling number of the voltage sampling points according to the preset time period and the preset voltage sampling period; if N is larger than the minimum sampling number, the step of calculating the slopes of the N-1 voltage sampling points corresponding to the N voltage sampling points is executed, the condition that continuous slope judgment of a plurality of points cannot be met can be met through voltage accidental reduction, the interference of voltage accidental reduction is eliminated, and the accuracy of judgment logic is improved.
Referring to fig. 9, fig. 9 is a flow chart illustrating a method for controlling an opening/closing member according to a third embodiment of the present invention.
Based on the second embodiment, in this embodiment, before the step S30, the method further includes:
step S301: and respectively comparing the slopes of the N-1 voltage sampling points with a preset slope threshold.
In a specific implementation, in this embodiment, whether the voltage change rate satisfies the preset condition may be determined by comparing the slopes of the N-1 voltage sampling points with a preset slope threshold, respectively.
Specifically, after the slopes of the N-1 voltage sampling points are respectively compared with the preset slope threshold, if the slopes of the N-1 voltage sampling points are all greater than the preset slope threshold, it is determined that the voltage change rate satisfies the preset condition in this embodiment. For example, assuming that the preset slope threshold is Kmin, the slopes of the calculated voltage sampling points are K1, K2, and K3, if (K1 > K min) & (K2 > Kmin) & (K3 > Kmin), that is, K1, K2, and K3 are simultaneously greater than the preset slope threshold Kmin, in this embodiment, it is determined that the voltage change rate satisfies the preset condition. When the engine is started, the voltage falling section has a slope minimum value Kmin, the value can be obtained by collecting the starting voltage waveform during development, in addition, the preset evil path threshold value can be correspondingly set according to actual requirements, and the limitation is not imposed in the embodiment.
Furthermore, in consideration of influences of system fluctuation, the number of sampling samples and the like, a scale factor is added in actual calculation to absorb the fluctuation, so that the robustness of the algorithm is improved.
In specific implementation, in this embodiment, an average slope of slopes of the N-1 voltage sampling points is further calculated, then the calculated average slope is compared with a target slope threshold, and if the calculated average slope is greater than the target slope threshold, it is determined that the voltage change rate satisfies a preset condition in this embodiment. For example, if the calculated slopes of the voltage sampling points are K1, K2, and K3, and the calculated average slope is (K1 + K2+ K3)/3, and if the target slope is Kt, it is determined that the voltage change rate satisfies the preset condition in this embodiment if (K1 + K2+ K3)/3 > Kt.
Further, the target slope threshold in this embodiment may be obtained by calculating a preset scale factor and a preset slope threshold, for example, the preset scale factor Py, where the preset slope threshold is Kmin, and the target slope threshold may be calculated as Py × Kmin, where the preset scale factor may be set correspondingly according to an actual requirement, and the present embodiment is not limited to this.
In the embodiment, the slopes of the N-1 voltage sampling points are respectively compared with a preset slope threshold; if the slopes of the N-1 voltage sampling points are all larger than the preset slope threshold, judging that the voltage change rate meets a preset condition, more accurately judging whether the voltage change rate meets the preset condition or not through the slopes of the voltage sampling points, and further calculating the average slope of the slopes of the N-1 voltage sampling points; if the average slope is larger than the target slope threshold, the voltage change rate is judged to meet the preset condition, the target slope threshold is obtained through proportional factor calculation, and fluctuation is absorbed through the proportional factor, so that the robustness of the algorithm is improved, and the accuracy of judgment is further improved.
Furthermore, an embodiment of the present invention also proposes a storage medium having stored thereon an opening-closing member control program that, when executed by a processor, implements the steps of the opening-closing member control method as described above.
Since the storage medium adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and details are not repeated herein.
