Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and more specifically, to a control method, device, vehicle and storage medium for an electric door handle. Background Art

[0002] The electric door handles of the car are different from traditional door handles. The surface is consistent with the waistline of the car, which makes the body lines more concise and smooth visually, and also reduces wind resistance to a certain extent. The electric door handles can be automatically deployed and retracted under the control of the body electronic control system, which is very technological and convenient for users.

[0003] There are two main types of electric door handles used in the market, one is the micro switch type and the other is the Hall motor type. The micro switch type is to build a micro switch into the door handle mechanism, and determine whether the door handle is fully extended and retracted by triggering the switch signal. The Hall motor type uses the Hall sensor to identify the number of revolutions of the motor, thereby knowing the position of the electric door handle, and then comparing it with the design position of the electric door handle to know whether the electric door handle is fully extended and retracted. Since the Hall motor type door handle does not need to arrange a switch on the handle mechanism, it reduces the cost while also reducing the requirements for the internal mechanism layout of the electric door handle. Therefore, the Hall motor type door handle has gradually replaced the micro switch type hidden door handle.

[0004] Since the Hall motor door handle needs to know the maximum Hall stroke of the electric door handle motor for position comparison during control, and the expansion Hall stroke of the electric door handle is determined based on the maximum Hall stroke, in the related art, the expansion of the electric door handle is controlled by using the set maximum Hall stroke. However, even when the same model of electric door handle is installed in different vehicles, the maximum Hall stroke may be different, so there will be a problem of insufficient accuracy when using the set maximum Hall stroke to control the electric door handle. Summary of the invention

[0012] In an optional embodiment, after determining the number of electric door handles whose second difference is greater than a second preset difference based on the second difference corresponding to each of the electric door handles, the method further includes: updating the number of abnormalities corresponding to each of the electric door handles currently recorded based on the electric door handles whose second difference is determined to be greater than the second preset difference; if the number of abnormalities corresponding to a target electric door handle among the multiple electric door handles reaches a preset number of abnormalities, outputting a prompt message, wherein the prompt message is used to prompt that there is an abnormality in the target electric door handle.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] In the related art, the calibrated maximum Hall stroke is written into the software to reduce the workload of matching and modification. However, as the electric door handle increases in usage time and wear, the maximum Hall stroke will change accordingly. If the electric door handle is deployed with the calibrated maximum Hall stroke, the drive control of the electric door handle will be limited.

[0027] In response to the technical problems raised by the background technology, the inventor proposed a control method, device, vehicle and storage medium for an electric door handle. After obtaining the deployment instruction for the electric door handle of the vehicle, the electric door handle is controlled to be deployed according to the reference Hall stroke. Since the reference Hall stroke is updated and recorded based on the maximum Hall stroke of the electric door handle obtained multiple times, the reference Hall stroke can be closer to the actual maximum Hall stroke of the electric door handle, so that the deployment of the electric door handle based on the reference Hall stroke is more accurate, thereby avoiding damage to the electric door handle. Moreover, determining the reference Hall stroke according to the maximum Hall stroke of the electric door handle can improve the compatibility between the electric door handle and the reference Hall stroke.

[0028] See also Figure 1 , Figure 1 FIG. 1 is a flow chart showing a control method for an electric door handle provided by an embodiment of the present application. In a specific embodiment, the control method for an electric door handle is applied to Figure 5 The control device 200 of the electric door handle and the vehicle equipped with the control device 200 of the electric door handle are shown.

[0029] The following will focus on Figure 1 The process shown is described in detail, and the control method of the electric door handle may specifically include the following steps:

[0030] Step S110: Acquire an expansion instruction for the electric door handle of the vehicle.

[0031] The expansion instruction may be obtained through an electrical signal, or through a wireless signal. The method for obtaining the expansion instruction is not specifically limited herein.

[0032] Exemplarily, the electric door handle can be deployed in response to the control sensor on the electric door handle detecting a human body within a preset distance, triggering a deployment instruction, and sending the deployment instruction to the drive motor of the electric door handle through an electrical signal, and the drive motor receiving the electrical signal controls the electric door handle to deploy. The electric door handle can also be deployed in response to the control button of the remote control triggering the deployment instruction, and sending the deployment instruction to the drive motor of the electric door handle through a wireless signal, and the drive motor receiving the wireless signal controls the electric door handle to deploy.

[0033] Step S120: In response to the deployment instruction, the electric door handle is controlled to be deployed based on the reference Hall stroke corresponding to the currently recorded electric door handle, wherein the reference Hall stroke is recorded after being updated according to the acquired maximum Hall stroke of the electric door handle, and the maximum Hall stroke is the Hall stroke of the electric door handle detected during the process of driving the electric door handle to deploy until the position of the electric door handle does not change.

[0034] Among them, Hall stroke means that the controller knows the handle position through the Hall signal, performs position recognition, and thus obtains the deployment angle of the electric door handle. Hall signal refers to the use of the Hall effect principle to generate a potential difference through the interaction between the magnetic field and the conductor.

[0035] The reference Hall stroke may be determined based on the average value corresponding to the maximum Hall stroke of the electric door handle obtained multiple times, or may be determined based on the weight of the maximum Hall stroke of the electric door handle obtained each time and the maximum Hall stroke of the electric door handle obtained each time. The method for determining the reference Hall stroke is not specifically limited herein. In an embodiment of the present application, the reference maximum Hall stroke is preferably updated based on the maximum Hall stroke of the electric door handle obtained multiple times.

[0036] In the embodiment of the present application, after the electric door handle obtains the deployment instruction, the electric door handle is controlled to be deployed based on the currently recorded reference Hall stroke, so as to determine whether the electric door handle is normally deployed based on the currently recorded reference Hall stroke. Controlling the electric door handle to be deployed based on the reference Hall stroke may be controlling the electric door handle to be deployed with the reference Hall stroke, or may be controlling the electric door handle to be deployed with a preset multiple of the reference Hall stroke, wherein the preset multiple is a value less than 1. The size of the Hall stroke after the electric door handle is deployed is not specifically limited here.

[0037] The control method of the electric door handle provided in the embodiment of the present application controls the deployment of the electric door handle according to the reference Hall stroke after obtaining the deployment instruction for the electric door handle of the vehicle. Since the reference Hall stroke is updated and recorded based on the maximum Hall stroke of the electric door handle obtained multiple times, the reference Hall stroke can be closer to the actual maximum Hall stroke of the electric door handle, making the deployment of the electric door handle controlled based on the reference Hall stroke more accurate, thereby avoiding damage to the electric door handle. In addition, determining the reference Hall stroke based on the maximum Hall stroke of the electric door handle can improve the compatibility between the electric door handle and the reference Hall stroke.

[0038] See also Figure 2 , Figure 2 FIG. 1 is a flow chart showing a control method for an electric door handle provided by another embodiment of the present application. Figure 2 The process shown is described in detail, and the control method of the electric door handle may specifically include the following steps:

[0039] Step S210: Acquire the maximum Hall strokes detected for the plurality of electric door handles.

[0040] In the embodiment of the present application, the maximum Hall stroke of the electric door handle can be obtained by using a sensor to read the corresponding Hall stroke when the electric door handle is unfolded to the position where the electric door handle does not change. The acquisition method can also be when the electric door handle is unfolded to the position where the electric door handle does not change, using a Hall stroke monitoring device to read the Hall stroke corresponding to the current electric door handle as the current maximum Hall stroke of the electric door handle. It should be noted that multiple times means at least twice. In the embodiment of the present application, in order to ensure the accuracy of the maximum Hall stroke of the electric door handle, the maximum Hall stroke of the electric door handle is obtained multiple times.

[0041] Furthermore, since the vehicle is provided with at least two door handles, the maximum Hall stroke of the electric door handles can be obtained by obtaining the maximum Hall stroke of a specified number of electric door handles or by obtaining the maximum Hall stroke of all electric door handles. The number of electric door handles for obtaining the maximum Hall stroke is not specifically limited herein.

[0042] Step S220: Obtain an average value of the maximum Hall strokes of the plurality of electric door handles as the current average value.

[0043] In the embodiment of the present application, the reference Hall stroke can be determined based on the obtained maximum Hall stroke by the average value of the maximum Hall strokes of multiple electric door handles, or by the corresponding weight of the maximum Hall stroke of a single electric door handle and the maximum Hall stroke obtained each time, or by the average value of the maximum Hall strokes of multiple electric door handles obtained multiple times. The method for determining the reference Hall stroke is not specifically limited here. Preferably, the average value of the maximum Hall strokes obtained multiple times is obtained as the reference Hall stroke.

[0044] Step S230: Obtain the difference between the maximum Hall stroke of each electric door handle and the current average value as the first difference corresponding to each electric door handle.

[0045] Step S240: If the first difference corresponding to each of the electric door handles is less than or equal to the first preset difference, the maximum Hall strokes of the multiple electric door handles obtained this time are recorded.

[0046] Step S250: If the first difference corresponding to any of the electric door handles is greater than the first preset difference, the maximum Hall strokes of the multiple electric door handles obtained this time are discarded.

[0047] Step S260: Return to the step of obtaining the maximum Hall strokes detected for the plurality of electric door handles respectively, until the maximum Hall strokes of the plurality of electric door handles obtained multiple times are recorded.

[0048] In the embodiment of the present application, the maximum Hall strokes of multiple electric door handles are obtained, and the average value of the maximum Hall strokes of the multiple electric door handles obtained at that time is calculated. Whether the maximum Hall stroke of the electric door handle at that time is valid is determined by the error between the maximum Hall stroke of each electric door handle and the average value at that time. If the first difference of each electric door handle is less than or equal to the first preset difference, it is judged that the maximum Hall stroke of all electric door handles obtained at that time is valid, and the maximum Hall stroke of each electric door handle obtained at that time is recorded. If the first difference of each electric door handle is greater than the first preset difference, it is judged that the maximum Hall stroke of all electric door handles obtained at that time is invalid, and the maximum Hall stroke of each electric door handle obtained at that time is discarded. And the acquisition of the maximum Hall stroke of each electric door handle is repeated multiple times until the maximum Hall stroke of each electric door handle obtained multiple times is recorded. When recording the maximum Hall stroke of the electric door handle, first judge whether the maximum Hall stroke of each electric door handle is valid according to the error between each electric door handle and the average value, so that the reference Hall stroke can be closer to the actual maximum Hall stroke of the electric door handle, thereby ensuring the drive control of the electric door handle. The first preset difference value may be 10% of the average value of the current time, or may be 8% of the average value of the current time. The first preset difference value is not specifically limited here.

[0049] It should be noted that each time before obtaining the maximum Hall stroke of the electric door handle, each electric door handle needs to be retracted and kept in place for a certain period of time to ensure that the electric door handle is retracted to the correct position, thereby ensuring that the maximum Hall stroke of the electric door handle obtained each time is the true maximum Hall stroke, reducing the error in obtaining the maximum Hall stroke. The certain period of time can be 300ms or 500ms, and this period is not specifically limited here.

[0050] Step S270: updating the recorded reference Hall stroke according to the maximum Hall strokes respectively recorded for a plurality of electric door handles on the vehicle, and recording the updated reference Hall stroke.

[0051] In the embodiment of the present application, since the maximum Hall stroke of the electric door handle may have errors due to mechanical or other reasons during use, the maximum Hall stroke obtained each time may be different. Therefore, the reference Hall stroke needs to be updated according to the maximum Hall stroke obtained each time to adapt to the current electric door handle.

[0052] In some embodiments, the recorded reference Hall stroke is updated according to the maximum Hall strokes recorded for multiple electric door handles on the vehicle, and the updated reference Hall stroke is recorded, including: according to the maximum Hall strokes of multiple electric door handles on the vehicle obtained by multiple records, the recorded reference Hall stroke is updated, and the updated reference Hall stroke is recorded.

[0053] In an implementation manner, the maximum Hall strokes of multiple electric door handles on the vehicle are obtained multiple times, and the recorded reference Hall strokes are updated using the multiple acquired maximum Hall strokes. The update method can be to update the reference Hall stroke with the maximum Hall stroke obtained each time, or to update the reference Hall stroke with the average value of the maximum Hall strokes obtained multiple times. The update method is not specifically limited herein.

[0054] Specifically, the method of updating the recorded reference Hall stroke according to the maximum Hall strokes of multiple electric door handles on the vehicle obtained through multiple records, and recording the updated reference Hall stroke, includes: determining the average value of the maximum Hall strokes of the multiple electric door handles on the vehicle obtained through multiple records. According to the average value, updating the recorded reference Hall stroke, and recording the updated reference Hall stroke.

[0055] In this embodiment, the reference Hall stroke is updated by using the average value of the maximum Hall strokes of multiple electric door handles on the vehicle obtained multiple times, so as to avoid the error caused by a single maximum Hall stroke.

[0056] Step S280: Obtaining an expansion instruction for the electric door handle of the vehicle.

[0057] Step S2980: In response to the deployment instruction, the electric door handle is controlled to deploy based on the reference Hall stroke corresponding to the currently recorded electric door handle, wherein the reference Hall stroke is recorded after being updated based on the acquired maximum Hall stroke of the electric door handle, and the maximum Hall stroke is the Hall stroke of the electric door handle detected during the process of driving the electric door handle to deploy until the position of the electric door handle does not change.

[0058] For detailed description of steps S280 to S290, please refer to steps S110 to S120 in the aforementioned embodiment, which will not be repeated here.

[0059] The control method of the electric door handle provided in the embodiment of the present application determines the reference Hall stroke by obtaining the maximum Hall stroke of the electric door handle multiple times, which can avoid the error caused by the maximum Hall stroke obtained once, and thus make the reference Hall stroke closer to the actual maximum Hall stroke of the electric door handle, thereby improving the compatibility between the reference Hall stroke and the electric door handle.

[0060] See also Figure 3 , Figure 3 FIG. 1 is a flow chart showing a control method for an electric door handle provided by another embodiment of the present application. Figure 3 The process shown is described in detail, and the control method of the electric door handle may specifically include the following steps:

[0061] Step S310: Obtaining an expansion instruction for electric door handles of the vehicle, where there are multiple electric door handles.

[0062] Step S320: In response to the deployment instruction, the electric door handle is controlled to be deployed based on the reference Hall stroke corresponding to the currently recorded electric door handle, wherein the reference Hall stroke is recorded after being updated according to the acquired maximum Hall stroke of the electric door handle, and the maximum Hall stroke is the Hall stroke of the electric door handle detected during the process of driving the electric door handle to deploy until the position of the electric door handle does not change.

[0063] For detailed description of steps S310 to S320, please refer to steps S110 to S120 in the aforementioned embodiment, which will not be repeated here.

[0064] Step S330: Obtain the Hall stroke corresponding to each of the electric door handles after being unfolded as the target Hall stroke.

[0065] Step S340: Obtain the difference between the target Hall stroke corresponding to each of the electric door handles and the reference Hall stroke as the second difference corresponding to each of the electric door handles.

[0066] Step S350: Based on the second difference corresponding to each of the electric door handles, determine the number of the electric door handles whose second difference is greater than a second preset difference.

[0067] Step S360: If the number of door handles is greater than the preset number, the maximum Hall stroke of the electric door handle is obtained, and the latest reference Hall stroke is determined based on the obtained maximum Hall stroke of the electric door handle, and the currently recorded reference Hall stroke is updated to the latest reference Hall stroke.

[0068] Among them, the target Hall stroke refers to the Hall stroke obtained after the driving motor of the electric door handle is driven and expanded according to the reference Hall stroke and maintained for a preset time, wherein the preset time can be 3s or 2.5s, and the preset time is not specifically limited here.

[0069] In the embodiment of the present application, the target Hall stroke of each electric door handle is compared with the reference Hall stroke of the current time to determine whether each electric door handle is normally deployed. If the second difference is less than or equal to the second preset difference, it is determined that the electric door handle is normally deployed. If the second difference is greater than the second preset difference, it is determined that the electric door handle is not normally deployed. According to the number of door handles, it is determined that multiple electric door handles on the vehicle cannot be deployed according to the current reference Hall stroke due to wear and tear. When the number of door handles is less than or equal to the preset number, it may be caused by the fault of the electric door handle itself. When the number of door handles is greater than the preset number, it can be determined that the error is caused by the wear and tear of multiple electric door handles. At this time, in order to adapt to the Hall stroke of the worn electric door handle so that the electric door handle can be normally deployed, it is necessary to determine a new reference Hall stroke based on the current maximum Hall stroke of the electric door handle so that the electric door handle can be deployed according to the latest reference Hall stroke thereafter, thereby avoiding the abnormal deployment of the electric door handle caused by using the set reference Hall stroke to control the deployment of the electric door handle. The second preset difference can be 10% of the reference Hall stroke or 8% of the reference Hall stroke, and the second preset difference is not specifically limited here. The preset number can be determined according to different vehicle models. For example, for a vehicle with four electric door handles, the preset number can be 3, and for a vehicle with two electric door handles, the preset number can be 1, and the preset number is not specifically limited here.

[0070] For example, see Figure 4 , Figure 4 A schematic diagram of the reference Hall stroke acquisition process in an embodiment of the present application is shown. Before obtaining the maximum Hall stroke of the handle, first drive the handle to retract and hold it for 500ms to ensure that the handle is completely retracted. Then drive the electric door handle to unfold until the unfolded position of the electric door handle no longer changes, and then obtain the maximum Hall stroke of the electric door handle. When the difference between the maximum Hall strokes of multiple electric door handles and the average value of the time is within the second preset difference, the maximum Hall strokes of the multiple electric door handles are recorded, and the electric door handles are driven to retract again until the maximum Hall strokes of multiple electric door handles are recorded. When the difference between the maximum Hall strokes of multiple electric door handles and the average value of the time is greater than the second preset difference, the secondary maximum Hall stroke is discarded, and the electric door handle is driven to retract again until the maximum Hall strokes of multiple electric door handles are recorded, and the reference Hall stroke is determined based on the recorded maximum Hall strokes of multiple electric door handles.

[0071] In some embodiments, after determining the number of the electric door handles whose second difference is greater than the second preset difference based on the second difference corresponding to each of the electric door handles, the method further includes: updating the number of abnormalities corresponding to each of the electric door handles currently recorded based on the determined electric door handles whose second difference is greater than the second preset difference. If the number of abnormalities corresponding to a target electric door handle among the multiple electric door handles reaches the preset number of abnormalities, a prompt message is output, and the prompt message is used to prompt that the target electric door handle has an abnormality.

[0072] Among them, the currently recorded number of abnormalities means that each time the electric door handle is deployed according to the deployment instruction, if the difference between the target Hall stroke corresponding to a certain electric door handle and the reference Hall stroke recorded at that time is greater than the second preset difference, then the electric door handle is recorded as an abnormal door handle, and the number of abnormalities of the electric door handle is recorded as 1, and in the subsequent deployment process of the electric door handle, if the difference between the target Hall stroke corresponding to the electric door handle and the reference Hall stroke recorded at that time is greater than the second preset difference, the number of abnormalities of the electric door handle is increased by 1.

[0073] In the implementation mode of the present application, when the number of abnormalities of a certain electric door handle reaches a preset number of abnormalities, a prompt message will be output to the user to prompt that the electric door handle is abnormal, so that the user can take corresponding abnormality handling measures for the electric door handle. Abnormality handling measures include but are not limited to replacing the electric door handle and repairing the electric door handle. No specific limitation is made here on abnormality handling measures.

[0074] Exemplarily, the electric door handle includes handle A and handle B, and the number of abnormalities corresponding to handle A is 1, and the number of abnormalities corresponding to handle B is 3. When the difference between the maximum Hall stroke of handle A and the reference Hall stroke obtained this time is greater than the second preset difference, and the difference between the maximum Hall stroke of handle B and the reference Hall stroke is less than the second preset difference. At this time, the number of abnormalities of handle A is increased by 1, and after the abnormality number is updated, the number of abnormalities of handle A is 2, and the number of abnormalities of handle B is 3.

[0075] The control method of the electric door handle provided in the embodiment of the present application, when there are more than a preset number of electric door handles with a target Hall stroke, and the difference between the target Hall stroke and the reference Hall stroke is greater than a second difference, re-acquires the maximum Hall stroke of the multiple electric door handles for multiple times to obtain the latest reference Hall stroke, and updates the reference Hall stroke to the latest reference Hall stroke, so that when the electric door handle process is subsequently carried out, the reference Hall stroke can be automatically corrected by referring to the updated reference Hall stroke, without modifying the calibrated reference Hall stroke in the software, thereby improving the compatibility between the reference Hall stroke and the electric door handle, and also ensuring the drive control of the electric door handle.
