Abstract

The present invention belongs to the field of vehicle control technology, and discloses a vehicle external handle control method, device, equipment and storage medium. This application obtains the response difference duration corresponding to each external handle when a handle pop-up signal is detected; controls the drive motor corresponding to each external handle to operate so that each external handle pops outward; stops the drive motor corresponding to the preset external handle when a pop-up position detection switch jumps; and controls the drive motors corresponding to other external handles in multiple external handles to continue operating based on the response difference duration. Since the preset external handle is determined to have completed popping out based on the jump of the pop-up position detection switch, the drive motors corresponding to other external handles in multiple external handles are controlled to continue operating based on the response difference duration corresponding to each external handle to ensure that all external handles can be completely popped out. The overall process only requires the deployment of one pop-up position detection switch, reducing the number of required pop-up position detection switches and related wiring harnesses.

[0001] The present invention relates to the field of vehicle control technology, and in particular to a vehicle external handle control method, device, equipment and storage medium. Background Art

[0002] With the development of vehicle technology, the use of hidden external handles is increasing. Existing hidden external handles generally have two position switches on each external handle, which are used to detect the closed and pop-up positions respectively. However, this method requires the installation of multiple position switches, and the large number of position switches will also lead to a large number of wiring harnesses, resulting in high costs for hidden external handles.

[0003] The above content is only used to assist in understanding the technical solution of the present invention and does not constitute an admission that the above content is prior art. Summary of the Invention

[0004] The main purpose of the present invention is to provide a vehicle external handle control method, device, equipment and storage medium, aiming to solve the technical problem of high installation cost of hidden external handles in the prior art.

[0005] To achieve the above-mentioned object, the present invention provides a vehicle external handle control method, the vehicle external handle control method being applied to a vehicle, wherein the vehicle is provided with a plurality of external handles, each of the plurality of external handles being provided with a closed position detection switch, and the plurality of external handles including a preset external handle provided with a pop-up position detection switch;

[0006] The vehicle outer handle control method comprises the following steps:

[0007] When a handle pop-up signal is detected, the response difference duration corresponding to each external handle is obtained;

[0008] Controlling the drive motors corresponding to the external handles to operate so that the external handles pop outward;

[0009] When the pop-up position detection switch jumps, the drive motor corresponding to the preset external handle is stopped;

[0010] According to the response difference duration, the driving motors corresponding to the other outer handles among the plurality of outer handles are controlled to continue to operate.

[0011] Optionally, when a handle pop-up signal is detected, the step of obtaining the response time difference corresponding to each external handle includes:

[0012] When a handle pop-up signal is detected, check whether it is the first pop-up;

[0013] If it is not the first pop-up, the response difference duration corresponding to each outer handle is obtained.

[0014] Optionally, after detecting whether the handle pops up for the first time when the handle pops up signal is detected, the method further includes:

[0015] If it is the first pop-up, get the maximum duration of continuous control;

[0016] The driving motors corresponding to the outer handles are controlled to operate according to the maximum continuous control time, so that the outer handles are ejected outward.

[0017] Optionally, the step of controlling the drive motors corresponding to other outer handles among the plurality of outer handles to continue operating according to the response difference duration includes:

[0018] Obtaining a calibrated driving voltage and a current driving voltage corresponding to the response difference duration;

[0019] If the current driving voltage is less than the calibrated driving voltage, the response difference duration is corrected according to the calibrated driving voltage and the current driving voltage.

[0020] Optionally, after the step of controlling the drive motors corresponding to other outer handles among the plurality of outer handles to continue operating according to the response difference duration, the method further includes:

[0021] When a handle closing signal is detected, the drive motors corresponding to the outer handles are controlled to operate so that the outer handles are retracted inwards and closed;

[0022] Obtain the transition moment of each closed position detection switch;

[0023] The response difference durations corresponding to the external handles are updated according to the jump timing.

[0024] Optionally, the step of updating the response difference duration corresponding to each external handle according to the jump moment includes:

[0025] Check whether there is a closed position detection switch whose jump moment cannot be obtained;

[0026] If there is no closed position detection switch whose jump moment cannot be obtained, the response difference duration corresponding to each external handle is updated according to the jump moment.

[0027] Optionally, after the step of controlling the drive motors corresponding to the outer handles to operate so that the outer handles pop outward, the method further includes:

[0028] If the continuous operation time of the control drive motor reaches a preset detection threshold and the pop-up position detection switch does not jump, then detect whether the closed position detection switch is in a state of jumping, and obtain a switch detection result;

[0029] The drive motors corresponding to the external handles are controlled to operate according to the control strategy corresponding to the switch detection result.

[0030] In addition, to achieve the above-mentioned purpose, the present invention further provides a vehicle outer handle control device, which includes the following modules:

[0031] A difference acquisition module is used to obtain the response difference duration corresponding to each external handle when a handle pop-up signal is detected;

[0032] A motor control module is used to control the operation of the drive motor corresponding to each external handle so that each external handle pops outward;

[0033] a jump detection module, configured to stop the drive motor corresponding to the preset external handle when the pop-up position detection switch jumps;

[0034] The secondary control module is configured to control the drive motors corresponding to the other outer handles among the plurality of outer handles to continue to operate according to the response difference duration.

[0035] In addition, to achieve the above-mentioned purpose, the present invention also proposes a vehicle outside handle control device, which includes: a processor, a memory, and a vehicle outside handle control program stored in the memory and runnable on the processor. When the vehicle outside handle control program is executed by the processor, the steps of the vehicle outside handle control method as described above are implemented.

[0036] In addition, to achieve the above objectives, the present invention also proposes a computer-readable storage medium, on which a vehicle outside handle control program is stored. When the vehicle outside handle control program is executed, the steps of the vehicle outside handle control method described above are implemented.

[0037] The present invention obtains the response difference duration corresponding to each external handle upon detecting a handle pop-up signal; controls the operation of the drive motor corresponding to each external handle to cause each external handle to pop outward; stops the drive motor corresponding to the preset external handle upon a toggle in the pop-up position detection switch; and controls the drive motors corresponding to other external handles in the multiple external handles to continue operating based on the response difference duration. Because the drive motors corresponding to other external handles in the multiple external handles are controlled to continue operating based on the response difference duration corresponding to each external handle upon determining that the preset external handle has completed pop-up based on the toggle in the pop-up position detection switch, ensuring that all external handles can be fully popped out, the entire process only requires the deployment of a single pop-up position detection switch, reducing the number of required pop-up position detection switches and the associated wiring harnesses.

[0049] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation to the electronic device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0051] exist Figure 1 In the electronic 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 electronic device of the present invention can be set in the vehicle outside handle control device, and the electronic device calls the vehicle outside handle control program stored in the memory 1005 through the processor 1001, and executes the vehicle outside handle control method provided by the embodiment of the present invention.

[0052] The embodiment of the present invention provides a vehicle outer handle control method, referring to Figure 2 , Figure 2 This is a flow chart of a first embodiment of a vehicle exterior handle control method according to the present invention.

[0053] In this embodiment, the vehicle external handle control method is applied to a vehicle, wherein the vehicle is provided with a plurality of external handles, each of which is provided with a closed position detection switch, and the plurality of handles includes a preset external handle provided with a pop-up position detection switch;

[0054] It should be noted that the preset external handle may be the external handle with the largest linear resistance among multiple external handles. When multiple external handles in the vehicle are simultaneously closed or ejected, the preset external handle may be the external handle that is closed or ejected first.

[0055] For ease of understanding, now combined Figure 3 This is for illustration only, but does not limit the present application. Figure 3 This is a schematic diagram of the switch settings of this embodiment, as shown in FIG. Figure 3 As shown, the vehicle includes four doors, namely the driver's door, the passenger door, the rear left door, and the rear right door. Each door is provided with a hidden external handle. In the prior art, a closed position detection switch (CDS SW) and a pop-up position detection switch (ODS SW) are provided at each external handle. At this time, the line resistance corresponding to the external handle provided on the rear right door is the largest. In this embodiment, the external handle on the rear right door can be used as the preset external handle, and the pop-up position detection switch provided at the preset external handle is retained. Then, the pop-up position detection switches provided at other external handles are removed, and the corresponding wiring harnesses are removed.

[0056] When the CDS SW is in the disconnected state, it indicates that the actuator is in the retracted state and the corresponding external handle is retracted; when the ODS SW is in the disconnected state, it indicates that the actuator is in the extended state and the corresponding handle is ejected.

[0057] The vehicle outer handle control method comprises the following steps:

[0058] Step S10: When a handle pop-up signal is detected, the response difference durations corresponding to the external handles are obtained.

[0059] It should be noted that the executing entity of this embodiment can be the vehicle external handle control device, and the vehicle external handle control device can be a controller inside the vehicle, such as a BCM controller, or it can be the vehicle itself, or other components in the vehicle that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment and the following embodiments, the vehicle external handle control method of this application is explained using the BCM controller as an example.

[0060] It should be noted that if a handle pop-up signal is detected, it means that the user is controlling all the outer handles of the vehicle to pop out. At this time, since the pop-up position detection switches other than the preset outer handles have been removed, only the pop-up position detection switches set at the preset outer handles can be used to determine whether the preset outer handle is completely popped out, but it is impossible to determine whether other outer handles are completely popped out. At this time, in order to ensure that the outer handles can be completely popped out, the response difference time corresponding to each outer handle can be obtained.

[0061] Among them, the response difference time corresponding to the external handle can be the difference between the time when the external handle responds and the preset time when the external handle responds. The response difference time corresponding to each external handle can be calibrated in advance by the vehicle management personnel, or calibrated according to the response difference of the previous closing action. This embodiment does not limit this.

[0062] Furthermore, since the vehicle may be used for the first time, the outer handle may be popped out for the first time, and the corresponding response difference time may not be calibrated. In order to distinguish such cases, step S10 in this embodiment may include:

[0063] When a handle pop-up signal is detected, check whether it is the first pop-up;

[0064] If it is not the first pop-up, the response difference duration corresponding to each outer handle is obtained.

[0065] It is understandable that if the outer handle is not popped out for the first time, it means that the response difference time has been calibrated before, and therefore, the response difference time corresponding to each outer handle can be obtained.

[0066] In a specific implementation, if the handle pops up for the first time, there is no pre-calibrated response difference time. In order to ensure that the outer handle can still be fully popped out, after detecting whether it is the first pop-up when the handle pops up signal is detected, the following steps may be further performed after detecting whether it is the first pop-up:

[0067] If it is the first pop-up, get the maximum duration of continuous control;

[0068] The driving motors corresponding to the outer handles are controlled to operate according to the maximum continuous control time, so that the outer handles are ejected outward.

[0069] It should be noted that the maximum duration of continuous control may be the maximum duration that the drive motor corresponding to the outer handle is allowed to continuously move in the pop-up direction.

[0070] It is understandable that by controlling the operation of the drive motor corresponding to each outer handle according to the maximum continuous control time, it is possible to ensure that the outer handle is controlled to pop out to the limit without damaging the outer handle, thereby ensuring that each outer handle can be fully popped out.

[0071] Step S20: controlling the drive motors corresponding to the external handles to operate so as to cause the external handles to pop outward.

[0072] It should be noted that controlling the driving motor corresponding to each outer handle to operate so that each outer handle pops outward may be controlling the driving motor corresponding to the outer handle to operate in a popping direction, thereby controlling the outer handle to pop outward.

[0073] In a specific implementation, according to the actual configuration of the vehicle, multiple external handles may correspond to the same drive motor, or different external handles may correspond to different drive motors, which is not limited in this embodiment.

[0074] Step S30: When the pop-up position detection switch jumps, the drive motor corresponding to the preset external handle is stopped.

[0075] It is understandable that if the pop-up position detection switch jumps, it means that the preset external handle has been completely popped out, and the operation of the drive motor corresponding to the preset external handle can be stopped at this time.

[0076] Step S40: controlling the drive motors corresponding to the other outer handles among the plurality of outer handles to continue to operate according to the response difference duration.

[0077] It should be noted that due to differences in wiring, there will be certain differences in the actual time it takes for each external handle to pop out completely, and the preset external handle is the first to complete popping out or closing. When the preset external handle pops out completely, the other external handles are not actually popped out completely. Therefore, it is necessary to continue to control the drive motors of the other external handles to continue running according to the response difference time, so as to ensure that each external handle pops out completely.

[0078] In actual use, if each outer handle uses a common drive motor, the maximum duration of the response difference corresponding to each outer handle can be obtained to control the maximum operation time of the drive motor, thereby ensuring that all outer handles are fully popped out.

[0079] If different external handles correspond to different drive motors, the drive motor corresponding to the external handle can be controlled to continue running for the response difference time corresponding to the external handle, thereby ensuring that the external handle is completely ejected.

[0080] Among them, in order to avoid the impact caused by the difference in motor operation, a compensation value can also be preset (for example: the compensation value is set to 50ms). When the drive motors corresponding to other external handles among the multiple external handles continue to operate according to the response difference time, the response difference time can be added to the compensation value, and the drive motors corresponding to other external handles among the multiple external handles continue to operate according to the value obtained after the addition.

[0081] In a specific implementation, it is possible that the pop-up position detection switch of a preset external handle may trip, but the closure detection switches of one or more other external handles may not trip. In this case, the drive motors corresponding to the other external handles can no longer be controlled to continue operating based on the response difference duration. Instead, the preset duration is directly obtained and the drive motors corresponding to the other external handles can be controlled to continue operating until the continuous operation duration reaches the preset duration. The preset duration can be pre-set by the vehicle manufacturer, such as 1500ms. If this occurs, the BCM controller will need to respond in this manner each time the user attempts to pop out the external handle until the thermal protection condition is triggered.

[0082] This embodiment detects the response difference durations corresponding to each external handle upon detecting a handle ejection signal; controls the corresponding drive motors of each external handle to cause it to eject outward; stops the drive motor corresponding to the preset external handle upon a toggle in the ejection position detection switch; and controls the drive motors corresponding to other external handles in the multiple external handles to continue operating based on the response difference durations. Because the control of the drive motors corresponding to other external handles in the multiple external handles is based on the response difference durations corresponding to each external handle upon determining that the preset external handle has ejected completely based on the toggle in the ejection position detection switch, ensuring that all external handles eject completely, the entire process requires only one ejection position detection switch, reducing the number of required ejection position detection switches and the associated wiring harnesses.

[0083] refer to Figure 4 , Figure 4 This is a flow chart of a second embodiment of a vehicle exterior handle control method according to the present invention.

[0084] Based on the first embodiment, the vehicle outside handle control method of this embodiment further includes, before step S40:

[0085] Step S31: obtaining the calibrated driving voltage and the current driving voltage corresponding to the response difference duration.

[0086] It should be noted that the calibrated driving voltage corresponding to the response difference time may be the driving voltage used when the driving motor is running when the response difference time is calibrated, and the current driving voltage may be the driving voltage in the driving motor at the current moment.

[0087] Step S32: If the current driving voltage is less than the calibrated driving voltage, the response difference duration is corrected according to the calibrated driving voltage and the current driving voltage.

[0088] It can be understood that if the current driving voltage is lower than the calibrated driving voltage, it means that the driving voltage of the driving motor at the current moment is lower. At this time, the driving motor cannot achieve the same effect as when calibrated by running for the same length of time. Therefore, the response difference duration needs to be corrected according to the calibrated driving voltage and the current driving voltage.

[0089] In a specific implementation, the correction of the response difference time according to the calibrated driving voltage and the current driving voltage may be based on a preset correction formula, and the response difference time is corrected according to the calibrated driving voltage and the current driving voltage.

[0090] The preset correction formula may be:

[0091] T comdif =T curdif *(V last / V current )

[0092] Where, T comdif Can be the corrected response difference duration, T curdif Can be the response difference time before correction, V last Can be used to calibrate the drive voltage, V current It can be the current driving voltage.

[0093] This embodiment obtains the calibrated driving voltage and current driving voltage corresponding to the response difference duration; if the current driving voltage is less than the calibrated driving voltage, the response difference duration is corrected based on the calibrated driving voltage and the current driving voltage. This correction based on the current and calibrated driving voltages prevents the actual ejection control of the outer handle from being affected by the driving voltage differences.

[0094] refer to Figure 5 , Figure 5 1 is a flow chart of a third embodiment of a vehicle exterior handle control method according to the present invention.

[0095] Based on the first embodiment described above, the vehicle outside handle control method of this embodiment further includes, after step S20:

[0096] Step S21: If the continuous operation time of the control driving motor reaches a preset detection threshold and the pop-up position detection switch does not jump, then detect whether the closed position detection switch is in a state of jumping to obtain a switch detection result.

[0097] It should be noted that the preset detection threshold may be set in advance by the vehicle manufacturer.

[0098] It is understandable that if the continuous operation time of the control drive motor reaches the preset detection threshold and the pop-up position detection switch does not jump, then the pop-up position detection switch set at the preset external handle may be abnormal. At this time, in order to respond reasonably, it is possible to detect whether the closed position detection switch is in a state of jumping to obtain the switch detection result.

[0099] Step S22: controlling the operation of the drive motors corresponding to the external handles according to the control strategy corresponding to the switch detection result.

[0100] It should be noted that if the switch detection result shows that all closed position detection switches have jumped, then in order to detect whether the pop-up position detection switch has failed, you can return to step S20 and try to execute the pop-up action again. If the pop-up position detection switch still does not jump after repeating the preset number of times, it can be determined that the pop-up position detection switch has failed, and the user can be prompted that a failure has occurred and maintenance is required.

[0101] If the switch detection result shows that none of the closed position detection switches have changed, it is possible that the detection switches are faulty, or the drive motor is faulty, resulting in the ejection action not being executed. In this case, a prompt can be given. If the user operates the outer handle to eject each time, the BCM controller needs to respond and try to control the drive motor to operate in the ejection direction for a preset duration until the BCM triggers the thermal protection condition. The preset duration can be pre-set by the vehicle manufacturer, such as setting the preset duration to 1500ms.

[0102] This embodiment detects whether the closed position detection switch is in a state of transition if the duration of continuous operation of the control drive motor reaches a preset detection threshold and the pop-up position detection switch has not transitioned, thereby obtaining a switch detection result. The control strategy corresponding to the switch detection result controls the operation of the drive motor corresponding to each external handle. If a transition of the position detection switch cannot be detected, the closed position detection switch is detected to determine whether it is in a state of transition. Further control is performed based on the detection result to determine the specific cause of the fault, facilitating user troubleshooting or repair.

[0103] refer to Figure 6 , Figure 6 This is a flow chart of a fourth embodiment of a vehicle exterior handle control method according to the present invention.

[0104] Based on the first embodiment described above, the vehicle outside handle control method of this embodiment further includes, after step S40:

[0105] Step S50: When a handle closing signal is detected, the drive motors corresponding to the outer handles are controlled to operate so as to retract the outer handles inwards and close them.

[0106] It should be noted that if a handle closing signal is detected, it means that the user wants to retract all the outer handles of the vehicle to a closed state. At this time, the drive motors corresponding to the outer handles can be controlled to run in the retraction direction to retract the outer handles inward to a closed state.

[0107] Step S60: Acquire the switching moment of each closed position detection switch when it switches.

[0108] It is understandable that when the outer handle retracts to the closed state, the closed position detection switch provided at the outer handle will jump, and the jumping moment when each closed position detection switch jumps is the moment when each outer handle retracts to the closed state.

[0109] Step S70: updating the response difference duration corresponding to each outer handle according to the jump time.

[0110] It should be noted that updating the response difference duration corresponding to each external handle according to the jump moment can be to calculate the jump moment corresponding to the jump of the closed position detection switch at the external handle and the jump moment corresponding to the jump of the preset closed position detection switch at the external handle, and use the difference as the response difference duration corresponding to the external handle, so as to obtain the latest response difference duration corresponding to each external handle, and use the response difference duration to overwrite and update the previously recorded response difference duration corresponding to each external handle.

[0111] Furthermore, to ensure the validity of the response difference time, before step S70 in this embodiment, the following steps may be further included:

[0112] Check whether there is a closed position detection switch whose jump moment cannot be obtained;

[0113] If there is no closed position detection switch whose jump moment cannot be obtained, the response difference duration corresponding to each external handle is updated according to the jump moment.

[0114] It should be noted that if there is no closed position detection switch that cannot obtain the jump moment, it means that the closing moment of each external handle can be accurately obtained at this time, and the calculated response difference time length corresponding to each external handle is guaranteed to be accurate. Therefore, the response difference time length corresponding to each external handle can be updated according to the jump moment.

[0115] However, if there is a closed position detection switch that cannot obtain the jump moment, it means that the moment when at least one external handle is closed cannot be determined. At this time, if the response difference duration corresponding to each external handle is updated according to the jump moment, some data may not be updated. Subsequently, controlling the pop-up of the external handle according to the response difference duration may cause equipment abnormality or even damage to the equipment. Therefore, the step of updating the response difference duration corresponding to each external handle according to the jump moment can be omitted at this time.

[0116] This embodiment controls the drive motors corresponding to each outer handle upon detecting a handle closing signal, causing the handles to retract and close inward. It also obtains the toggling time of each closed position detection switch, and updates the response difference duration corresponding to each outer handle based on the toggling time. Because the response difference duration for each outer handle is updated based on relevant data related to the outer handle retraction, the response difference durations subsequently obtained when controlling the outer handles to pop out are more accurately aligned with the actual vehicle situation, thus minimizing the impact of hardware aging and other factors on the outer handle pop-out control.

[0117] In addition, an embodiment of the present invention further provides a storage medium storing a vehicle outside handle control program. When the vehicle outside handle control program is executed by a processor, the steps of the vehicle outside handle control method described above are implemented.

[0118] Reference Figure 7 , Figure 7 This is a structural block diagram of the first embodiment of the vehicle outside handle control device of the present invention.

[0119] like Figure 7 As shown, the vehicle outer handle control device proposed in the embodiment of the present invention includes:

[0120] The difference acquisition module 10 is used to acquire the response difference duration corresponding to each outer handle when a handle pop-up signal is detected;

[0121] The motor control module 20 is used to control the operation of the drive motor corresponding to each outer handle so that each outer handle pops outward;

[0122] a jump detection module 30, configured to stop the drive motor corresponding to the preset external handle when the pop-up position detection switch jumps;

[0123] The secondary control module 40 is configured to control the drive motors corresponding to the other outer handles among the plurality of outer handles to continue to operate according to the response difference duration.

[0124] This embodiment detects the response difference durations corresponding to each external handle upon detecting a handle ejection signal; controls the corresponding drive motors of each external handle to cause it to eject outward; stops the drive motor corresponding to the preset external handle upon a toggle in the ejection position detection switch; and controls the drive motors corresponding to other external handles in the multiple external handles to continue operating based on the response difference durations. Because the control of the drive motors corresponding to other external handles in the multiple external handles is based on the response difference durations corresponding to each external handle upon determining that the preset external handle has ejected completely based on the toggle in the ejection position detection switch, ensuring that all external handles eject completely, the entire process requires only one ejection position detection switch, reducing the number of required ejection position detection switches and the associated wiring harnesses.

[0125] Furthermore, the difference acquisition module 10 is further configured to detect whether it is the first pop-up when a handle pop-up signal is detected; if it is not the first pop-up, acquire the response difference durations corresponding to the outer handles.

[0126] Furthermore, the difference acquisition module 10 is further configured to acquire a maximum duration of continuous control if the handle pops out for the first time; and control the operation of the drive motor corresponding to each outer handle according to the maximum duration of continuous control to cause each outer handle to pop out.

[0127] Furthermore, the secondary control module 40 is also used to obtain the calibrated driving voltage and the current driving voltage corresponding to the response difference time; if the current driving voltage is less than the calibrated driving voltage, the response difference time is corrected according to the calibrated driving voltage and the current driving voltage.

[0128] Furthermore, the secondary control module 40 is also used to control the operation of the drive motors corresponding to each external handle when a handle closing signal is detected, so that each external handle retracts inward and closes; obtain the jump moment when each closed position detection switch jumps; and update the response difference duration corresponding to each external handle according to the jump moment.

[0129] Furthermore, the secondary control module 40 is also used to detect whether there is a closed position detection switch that cannot obtain the jump moment; if there is no closed position detection switch that cannot obtain the jump moment, the response difference duration corresponding to each external handle is updated according to the jump moment.

[0130] Furthermore, the motor control module 20 is also used to detect whether the closed position detection switch is in a state of jumping if the continuous operation time of the controlled drive motor reaches a preset detection threshold and the pop-up position detection switch has not jumped, so as to obtain a switch detection result; and control the operation of the drive motor corresponding to each external handle according to the control strategy corresponding to the switch detection result.

[0131] It should be understood that the above is only an example and does not constitute any limitation to the technical solution of the present invention. In specific applications, those skilled in the art can make settings as needed, and the present invention does not impose any limitation on this.
