[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] At present, during the initialization process of the electronic valve, the mechanical stop position is hit with a fixed duty cycle. Therefore, when the vehicle is actually used in different working conditions, there is a risk of the electronic valve being blocked and there may also be a risk of tooth breakage, which in turn affects the performance of the entire vehicle.

[0028] Based on this, an electronic valve control method, device and electronic equipment provided by the embodiments of the present invention can effectively alleviate the above technical problems.

[0029] To facilitate understanding of this embodiment, a control method for an electronic valve disclosed in an embodiment of the present invention is first introduced in detail.

[0030] In a possible implementation manner, an embodiment of the present invention provides a method for controlling an electronic valve, such as Figure 1 A flow chart of a method for controlling an electronic valve is shown, the method comprising the following steps:

[0031] Step S102, in response to the power-on operation of the electronic valve, obtaining the operating parameters of the electronic valve;

[0032] The operating parameters in the embodiment of the present invention include current parameters of the electronic valve, or Hall parameters of the electronic valve;

[0033] Step S104, determining whether the operating parameters meet the preset control conditions;

[0034] Step S106: if yes, stop the motor corresponding to the electronic valve from rotating.

[0035] In actual use, when the electronic valve is powered on, the operating parameters can be obtained according to the preset time interval. For example, the time interval can be set small enough to realize real-time acquisition of the operating parameters, and then when the operating parameters meet the control conditions, the impact of the electronic valve body on the mechanical stop position can be timely reduced.

[0036] Therefore, the control method of the electronic valve provided in the embodiment of the present invention can respond to the power-on operation of the electronic valve, obtain the operating parameters of the electronic valve, and determine whether the operating parameters meet the pre-set control conditions; if so, stop the rotation of the motor corresponding to the electronic valve, and the above-mentioned operating parameters include the current parameters of the electronic valve, or the Hall parameters of the electronic valve, which can directly monitor the torque of the electronic valve, thereby preventing the electronic valve from directly hitting the mechanical stop position with a large torque, thereby reducing the risk of electronic valve jamming and tooth breaking.

[0037] In actual use, the above operating parameters can be configured according to actual use requirements, that is, whether to select current parameters or Hall parameters as operating parameters can be set according to actual use conditions, and the embodiment of the present invention does not limit this.

[0038] Furthermore, in order to obtain the operating parameters, in the embodiment of the present invention, a current sampling circuit and a Hall sampling circuit may be pre-configured in the control circuit of the electronic valve. Thus, when obtaining the operating parameters of the electronic valve, if the pre-configured operating parameters are the current parameters of the electronic valve, the pre-configured current sampling circuit is started; the current parameters of the electronic valve are sampled by the current sampling circuit; and the sampled current parameters are determined as the operating parameters of the electronic valve.

[0039] For ease of understanding, Figure 2 A schematic diagram of a current sampling circuit is shown, such as Figure 2 As shown, it includes an input terminal IN and an output terminal OUT, wherein the input terminal IN is connected to the input terminal of the electronic valve to sample the current parameters flowing through the electronic valve, and the output terminal is connected to a controller, such as the controller of the control circuit of the electronic valve, so that the controller can monitor the current parameters flowing through the electronic valve in real time.

[0040] Specifically, the current is input from the input terminal IN, passes through the operational amplifier U1, and then enters the controller MCU from the output terminal for collection, and, Figure 2 The resistors R1, R2 and R4 at the input end and the resistor R3 at the output end are also output. In addition, the grounding capacitors C1, C2 and C3 are also shown. It should be understood that Figure 2 What is shown is only one possible current sampling circuit. In other implementations, the current sampling circuit may be configured according to actual usage, and the embodiment of the present invention is not limited thereto.

[0041] Furthermore, if the above operating parameters are Hall parameters of the electronic valve, a pre-configured Hall sampling circuit is started; the Hall parameters of the electronic valve are sampled by the Hall sampling circuit; and the sampled Hall parameters are determined as the operating parameters of the electronic valve.

[0042] For ease of understanding, Figure 3 A schematic diagram of a Hall sampling circuit is shown, such as Figure 3 As shown, U2 is a Hall switch, and the controller MCU collects Hall parameters from the output terminal OUT and counts, where: Figure 3 In FIG. 1 , the peripheral resistors R1 and R2 of the Hall switch and the supply voltage VCC are also shown. It should be understood that Figure 3 What is shown is only one possible Hall sampling circuit. In other implementations, the Hall sampling circuit may also be configured according to actual usage, and the embodiment of the present invention is not limited to this.

[0043] Furthermore, for the above-mentioned current parameters or Hall parameters, a parameter change curve can be generated for the sampled operating parameters; then the change amount of the operating parameters is calculated according to the parameter change curve; and it is further determined whether the change amount is greater than a pre-configured change threshold; if so, it means that the operating parameters meet the pre-set control conditions.

[0044] Specifically, when calculating the change amount of the operating parameter, the slope of the parameter change may be calculated according to the parameter change curve; and the slope may be determined as the change amount of the operating parameter.

[0045] Furthermore, when judging whether the change at this time is greater than the pre-configured change threshold, it is necessary to consider the current operating environment of the electronic valve, that is, obtain the current power supply voltage of the electronic valve, and the temperature parameters of the environment in which the electronic valve is located; search for the slope setting value corresponding to the power supply voltage and temperature parameters in the pre-configured slope change table; wherein the slope change table pre-records the slope setting values ​​corresponding to different temperature parameter intervals under different power supply voltages; then the slope setting value found is determined as the change threshold; further judge whether the slope is greater than the found change threshold, and if so, determine that the change is greater than the pre-configured change threshold.

[0046] In addition, when judging whether the change is greater than a pre-configured change threshold, the above slope can also be obtained according to a pre-set time interval. If the difference between the currently obtained slope and the previously obtained slope is greater than the preset difference threshold, it is determined that the change is greater than the pre-configured change threshold.

[0047] For ease of understanding, take the current parameter as an example. Figure 4FIG. 1 shows a parameter change curve of a current parameter, that is, the change relationship between the current parameter and time after the electronic valve is powered on, wherein the horizontal axis represents time in milliseconds, and the vertical axis represents current in milliamperes. Moreover, after the electronic valve is powered on, the current parameter gradually increases with time. When the slope change is large, such as Figure 4 The position indicated by the arrow in the middle indicates that the current parameter rises quickly, the torque of the electronic valve increases quickly, and it is easy for the large torque of the electronic valve to hit the mechanical stop position. Therefore, the above calculation of the change and the judgment process with the change threshold can immediately detect the phenomenon of large changes in operating parameters.

[0048] Further, the following Table 1 shows a possible implementation of a slope change table, which respectively shows the temperature parameter ranges corresponding to different power supply voltages, and the slope setting values ​​T corresponding to the temperature parameter ranges. Taking T1 as an example, T1 represents the slope setting value corresponding to -40°C to 25°C, T2 represents the slope setting value corresponding to 25°C to 90°C, and so on.

[0049] Table 1:

[0050]

[0051] In actual use, based on the above Table 1, the slope setting value T can be determined according to the current supply voltage value of the electronic valve and the ambient temperature. The electronic valve can collect the current value or Hall number every 50ms as the current parameter or Hall parameter, calculate the difference of the current value or Hall number, and divide the difference by 50ms to get the corresponding current value or Hall number slope. When it is detected that the current value or Hall number slope of the electronic valve is greater than the set value T, the motor is stopped, or the slope calculated currently is compared with the slope calculated last time. If the current calculated slope minus the previous calculated slope is greater than X, the motor is stopped. Both methods can reduce the impact of the valve body of the electronic valve on the mechanical stop position, avoid direct large torque hitting the mechanical stop position, and thus reduce the risk of electronic valve blocking and broken teeth.

[0052] Further, based on the above embodiments, the present invention also provides a control device for an electronic valve, such as Figure 5 A schematic structural diagram of a control device for an electronic valve is shown, the device comprising:

[0053] A response module 50, configured to respond to the power-on operation of the electronic valve and obtain operating parameters of the electronic valve, wherein the operating parameters include current parameters of the electronic valve or Hall parameters of the electronic valve;

[0054] A judging module 52 is used to judge whether the operating parameters meet the preset control conditions;

In the implementation process, each step of the above method can be completed by the hardware integrated logic circuit in the processor 61 or the instructions in the form of software.
