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 high-speed random access Memory (Random Access Memory, RAM) Memory or a stable Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the structure 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 shown, or may combine certain components, or a different arrangement of components.
As shown in fig. 1, an operating system, a network communication module, a user interface module, and an opening and closing member control program may be included in the memory 1005 as one type of storage medium.
In the open-close 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 open-close member control apparatus of the present invention may be provided in the open-close member control apparatus, which invokes the open-close member control program stored in the memory 1005 through the processor 1001, and executes the open-close member control method provided by the embodiment of the present invention.
An embodiment of the invention provides a method for controlling an opening and closing member, referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the method for controlling an opening and closing member.
In this embodiment, the method for controlling the opening and closing member includes the steps of:
step S10: and in the process of moving the opening and closing member, acquiring the working voltage and current of the driving mechanism corresponding to the opening and closing member.
In this embodiment, the execution body of this embodiment may be the opening and closing member control device, which has functions of data processing, data communication, program running, and the like, and the opening and closing member control device may be a controller in an automobile. Of course, other devices with similar functions may be used, and the implementation conditions are not limited thereto. For convenience of explanation, the present embodiment will be described taking an open-close member control apparatus as an example.
In the process of opening or closing the electric opening and closing object of the vehicle, the instant of starting the engine or the high-power electric appliance can cause the rapid reduction of the power supply voltage of the storage battery, and simultaneously, the voltage of the opening and closing object driving mechanism also rapidly reduces, thereby causing the reduction of the opening and closing speed of the opening and closing object driving mechanism. The anti-pinch function of the electric opening and closing object is that an external object or person blocks the normal movement of the opening and closing element, so that the opening and closing speed of the opening and closing element is reduced. These two different scenarios are prone to false reversals or false movements of the motorized shutters. For this situation, taking an electric vehicle as an example, when the power supply voltage changes rapidly, the voltage drops to a certain amplitude V1, and the opening and closing speed drops; if the voltage is continued for more than a certain time delta t1, the electric car door pauses to move, so that inconvenience, discomfort or scaring to a customer caused by the wrong reversal of the car door are avoided, and the previous electric movement is continued after the voltage is restored to V1'.
It should be emphasized that the conventional method requires that the voltage drop below a certain voltage to perform the erroneous clamping prevention judgment, so as to perform the erroneous clamping prevention control, for example, as shown in fig. 3, the conventional method requires that the voltage drop below 9V to perform the judgment, and if the starting voltage does not reach 9V or lower, the judgment is not performed. Further, the current method also detects whether the duration after the voltage drops to a certain value meets the condition, as shown in fig. 4, if the voltage rises to 9V or more at time T2, it is determined that no false pinching is generated, but from the perspective of the waveform diagram, the voltage value is relatively low, the driving speed is low, and the motion of the door with false pinching cannot be controlled according to the current scheme.
In order to solve the above-mentioned technical problem, in this embodiment, by the energy change caused by the decrease in the speed of the opening and closing member, it is determined whether or not the false pinch prevention is triggered, so as to control the opening and closing member.
In the present embodiment, the opening and closing member is an electric opening and closing member, and the opening and closing member may be a member such as an electric side door or an electric tailgate, for example, a vehicle.
In a specific implementation, the sudden drop of voltage can cause the anti-pinch of the system to reverse, the power supply voltage of the electric vehicle door changes to cause the electric vehicle door to move in an incorrect direction in the opening and closing movement process, for example, the electric vehicle door suddenly reverses to open in the closing process of the vehicle door, and the electric vehicle door is started by a driver in the vehicle or a high-power electric appliance in the opening and closing movement process of the electric vehicle door or the front and rear passenger/incoming vehicle in case of abnormal danger, for example, the electric vehicle door or the high-power electric appliance is started by the driver in the opening and closing movement process of the electric vehicle door, and the control logic disorder causes the wrong reverse rotation of the back door to cause injury.
Step S20: and when the working voltage drop is detected, acquiring the input energy change of the driving mechanism according to the working voltage and the current.
In a specific implementation, the manner adopted in the present embodiment is to calculate the input energy change of the driving mechanism according to the operating voltage and the current, that is, when the operating voltage of the driving mechanism decreases, the operating voltage of the driving mechanism is recorded from the time of decreasing the operating voltage in the present embodiment, and the input energy change of the driving mechanism in a period of time, that is, a preset period of time is recorded, so as to determine whether the false pinch prevention is possibly triggered due to the voltage decrease, for example, if the normal vehicle is in a condition of starting pinch prevention at 40ms, the door is reversed, but in the present embodiment, whether the false pinch prevention is generated is determined before 40 ms. The preset time period may be a minimum value under each working condition that affects the door false inversion and is measured during development, and of course, may also be set to other time periods according to actual requirements, which is not limited in this embodiment. For example, as shown in fig. 5, the input energy variation of the drive mechanism in the period from t1 to t2 is calculated in the present embodiment. The area of the shadow part multiplied by the current integral corresponding to each moment is equal to the work of small voltage drop, the speed of the opening and closing member is reduced after the work is small, and the work is equivalent to the virtual work of the tail gate when encountering an anti-clamping barrier in the closing process, namely, the input energy of the driving mechanism is changed after the speed of the opening and closing member is reduced.
Further, in this embodiment, the input energy change of the driving mechanism is used to determine whether the false pinching prevention will be caused, so before determining whether the input energy change of the driving mechanism meets the preset condition, it is further determined whether the voltage after the pressing reaches the minimum voltage for starting the false pinching prevention determination.
In a specific implementation, in this embodiment, the reduced voltage is obtained, and then the reduced voltage is compared with a preset voltage threshold, and if the reduced voltage reaches the preset voltage threshold, a subsequent determination of the change of the input energy of the driving mechanism is performed. For example, as shown in fig. 5, when the voltage drop reaches the preset voltage threshold v1 at time t1, the input energy variation of the driving mechanism in the time period from t1 to t2 is calculated in the present embodiment, and it is determined whether or not the false pinching is occurred by the variation in the time period.
Step S30: and controlling the opening and closing member to stop moving when the input energy change of the driving mechanism meets a preset condition.
In a specific implementation, after the input energy variation of the driving mechanism is obtained, in this embodiment, it is determined whether the input energy variation of the driving mechanism meets a preset condition, if the input energy variation of the driving mechanism meets the preset condition, it is indicated that the opening and closing member may possibly decrease in speed due to insufficient driving force caused by voltage decrease, and in this case, the opening and closing member is controlled to stop moving, so that occurrence of false pinching prevention is effectively avoided.
In the embodiment, the working voltage and the current of the driving mechanism corresponding to the opening and closing member are obtained in the process of moving the opening and closing member; when the working voltage drop is detected, acquiring the input energy change of the driving mechanism according to the working voltage and the working current; when the input energy change of the driving mechanism meets the preset condition, the opening and closing member is controlled to stop moving, and the situation that the voltage dip possibly causes the false anti-pinch is triggered at the moment can be judged by paying attention to the input energy change of the driving mechanism and meeting the preset condition, and then the opening and closing member is controlled to stop moving in time, so that the problem that an electric opening and closing object abnormally moves in the power voltage dip can be reliably solved, and the movement of the electric opening and closing member accords with expectations.
Referring to fig. 6, fig. 6 is a flowchart of a second embodiment of a method for controlling an opening and closing member according to the present invention.
Based on the first embodiment, in the method for controlling an opening and closing member of the present embodiment, the step S20 specifically includes:
step S201: and calculating according to the working current, the working voltage and a preset time period to obtain the input energy change of the driving mechanism.
In a specific implementation, after the working voltage and the working current are obtained, the output energy variation of the driving structure is further calculated by combining with a preset voltage threshold in the embodiment, and the preset voltage threshold in the embodiment is the minimum voltage for starting the false pinch-proof determination, such as V1 shown in fig. 5.
Further, in this embodiment, the calculated input energy change of the driving structure in the preset time period is that when the voltage drops to reach the preset voltage threshold, the corresponding moment, that is, the first moment is recorded in this embodiment, and then the first moment is taken as a reference, and the preset time period is combined at the same time, that is, the corresponding second moment is obtained, and the calculated input energy change of the driving mechanism is obtained according to the first moment, the second moment, the working current, the working voltage and the preset voltage threshold.
In this embodiment, the foregoing process is illustrated with reference to fig. 5, where the preset voltage threshold is V1, the first time is t1, the second time is t2, and if the obtained working voltage of the driving structure is Ut, and the current is It, the input energy change of the driving mechanism can be calculated and obtained:
By the method, the input energy change of the driving mechanism can be accurately calculated, and the energy change voltage is reduced to do little work.
In the embodiment, a first moment corresponding to the working voltage reaching a preset voltage threshold is obtained; determining a second moment corresponding to the first moment based on a preset time period; and performing differential calculation according to the first moment, the second moment, the working current, the working voltage and a preset voltage threshold value to obtain the input energy change of the driving mechanism, and accurately calculating the energy change generated by the driving structure due to the speed reduction of the opening and closing member, thereby improving the accuracy of false anti-pinch judgment.
Referring to fig. 7, fig. 7 is a schematic flow chart of a third embodiment of a control method for an opening and closing member according to the present invention.
Based on the above-described second embodiment, a third embodiment of an opening-closing member control method of the present invention is proposed.
In this embodiment, before the step S30, the method further includes:
step S301: the input energy variation of the drive mechanism is compared with a preset energy variation.
In particular, in this embodiment, after the input energy variation of the driving mechanism is calculated, it is determined whether the input energy variation of the driving mechanism satisfies the preset condition by comparing the input energy variation of the driving mechanism with the preset energy variation. If the input energy variation of the driving mechanism is greater than the preset energy variation, it is determined that the input energy variation of the driving mechanism satisfies the preset condition.
Specifically, the preset energy change in this embodiment may be the virtual work of the force measuring spring, for example, as shown in fig. 8, when an obstacle is encountered, the force measuring spring is equivalent to the force measuring spring encountered when the door is closed during calibration. The spring is compressed to a certain value, the speed of the corresponding tail gate is reduced to a corresponding amount, and the anti-clamping module starts anti-clamping judgment after recognizing that the speed is reduced. Mechanical anti-pinch judgment: during the time of delta T (=t2—t1), if the speed of the tail gate movement decreases to a certain value, the ECU will determine that the tail gate encounters an obstacle and activate anti-pinch. Assuming that the anti-pinch reversal is initiated when the target force value is set to 120N, this is equivalent to the force spring being compressed 12mm. Assuming spring compression amount flag=s, spring force f=10×s, the virtual work of the force measuring spring at this time:
It should be noted that, the virtual work made by the calculated spring is equivalent to the kinetic energy change of the speed reduction, that is, P tan is the preset energy change, that is, the input energy change of the driving mechanism during normal anti-pinch should be smaller than or consistent with the kinetic energy change, if the input energy change is larger than the preset energy change, it is determined that the false anti-pinch is triggered.
Further, the coefficient is introduced in the present embodiment to make further determination in consideration of tolerance fluctuation, position fluctuation, friction fluctuation, and the like of the opening and closing member.
In a specific implementation, the present embodiment further compares the input energy variation of the driving mechanism with the target energy variation, and determines whether the input energy variation of the driving mechanism satisfies the preset condition by comparing the input energy variation of the driving mechanism with the target energy variation. If the input energy variation of the driving mechanism is greater than the target energy variation, it is determined that the input energy variation of the driving mechanism satisfies a preset condition. For example, assuming that the calculated input energy variation of the driving mechanism is P U and assuming that the target energy variation is Pt, if P U > Pt, it is determined in the present embodiment that the input energy variation of the driving mechanism satisfies the preset condition.
Further, the target energy change in this embodiment may be obtained by calculating a preset coefficient and a preset energy change, for example, the preset coefficient is K, and the preset energy change Ptan is the target energy change k× Ptan, and if P U > k× Ptan, it is determined in this embodiment that the input energy change of the driving mechanism meets a preset condition, where the preset coefficient K may be set accordingly according to the actual requirement, and this is not limited in this embodiment.
The present embodiment compares the input energy variation of the driving mechanism with a preset energy variation; if the input energy change of the driving mechanism is larger than the preset energy change, judging that the input energy change of the driving mechanism meets the preset condition, accurately judging whether the input energy change of the driving mechanism meets the preset condition or not, calculating the target energy change according to the preset coefficient and the preset energy change, and comparing the input energy change of the driving mechanism with the target energy change; if the input energy change of the driving mechanism is larger than the target energy change, the input energy change of the driving mechanism is judged to meet the preset condition, interference of tolerance fluctuation, position fluctuation, friction fluctuation and other factors can be effectively eliminated, robustness of an algorithm is improved, and judging accuracy is further improved.
In addition, the embodiment of the invention also provides a storage medium, on which an opening and closing member control program is stored, which when executed by a processor, implements the steps of the opening and closing member control method as described above.
Because the storage medium adopts all the technical schemes of all the embodiments, the storage medium has at least all the beneficial effects brought by the technical schemes of the embodiments, and the description is omitted here.
