Description

Technical Field

[0001] This application relates to the field of automotive automatic control technology, and more specifically, to a hidden door handle control method and device, and a vehicle. Background Technology

[0002] Concealed door handles are increasingly used in passenger vehicles, becoming a major symbol of automakers' technological prowess. Currently, the main types of concealed door handles on the market are manual and electric. Manual handles require no control logic, while electric handles are controlled by triggering a switch to unfold or fold the handle.

[0003] Currently, most mainstream car models separate the trigger switches for keyless entry and manual folding / unlocking to prevent control logic conflicts. A few models use a shared solution between the keyless entry microswitch and the handle microswitch. The main problem with this shared solution is that the handle needs to be unfolded when the door lock is unlocked, while pressing the microswitch to activate the keyless locking function generally has a time delay, which may result in the locking logic being executed even after the handle is unfolded.

[0004] To avoid this conflict, door handle control typically involves multiple presses, each performing a different function. For example, when the door handle is in the folded position and the lock is unlocked, pressing the microswitch for the first time unfolds the handle; pressing it again with the handle unfolded locks the door. This method requires multiple presses of the microswitch each time the user wants to perform a keyless locking action, thus reducing the user experience. Summary of the Invention

[0005] This application addresses the shortcomings of existing methods by proposing a concealed door handle control method, device, and vehicle to solve the technical problem that existing concealed door handles require multiple presses of a microswitch to perform keyless locking when the door lock is in the folded state and the door handle is in the unlocked state.

[0006] In the first aspect, embodiments of this application provide a method for controlling a concealed car door handle, including: acquiring the current door lock status and door handle status in real time;

[0007] Acquire the first press signal of the door handle micro switch in the initial state; the initial state refers to the current door lock state and door handle state.

[0008] Based on the first press signal, detect the car key signal;

[0009] If a car key signal is detected, a door unlocking command or a door locking command is generated after a first preset time delay, based on the first pressing signal and the door lock status, in order to control the switching of the door lock status.

[0010] Based on the first pressing signal, the door handle state, and the door lock state, a handle unfolding command or handle folding command is generated after a second preset time delay to control the door handle state switching; wherein, the second preset time is greater than the first preset time.

[0011] In some embodiments, detecting the car key signal based on the first pressing signal includes: generating a detection signal for the car key signal when the first pressing signal is received.

[0012] In some embodiments, if a car key signal is detected, generating a door unlock command or a door lock command after a first preset time delay based on the first pressing signal and the door lock state to control the switching of the door lock state includes:

[0013] If the door lock is in the locked state and the door handle is in the folded state, when the car key signal is detected, after receiving the first pressing signal and delaying for a first preset time, a door unlocking command is generated to control the door lock to switch from the locked state to the unlocked state.

[0014] If the door lock is in the unlocked state and the door handle is in the unfolded state, when the car key signal is detected, a door locking command is generated after receiving the first pressing signal and delaying for a first preset time, which is used to control the door lock to switch from the unlocked state to the locked state.

[0015] In some embodiments, the step of generating a handle unfolding command or a handle folding command after a second preset time delay based on the first pressing signal, the door handle state, and the door lock state, to control the door handle state switching, includes:

[0016] If the door lock is in the unlocked state and the door handle is in the folded state, a handle unfolding command is generated after receiving the first pressing signal and delaying for a second preset time, which is used to control the door handle to switch from the folded state to the unfolded state.

[0017] If the door lock is in the locked state and the door handle is in the unfolded state, a handle folding command is generated after receiving the first pressing signal and delaying for a second preset time, which is used to control the door handle to switch from the unfolded state to the folded state.

[0018] In some embodiments, if a car key signal is detected, generating a door unlock command or a door lock command after a first preset time delay based on the first pressing signal and the door lock state to control the switching of the door lock state further includes:

[0019] If the door lock is in the unlocked state and the door handle is in the folded state, when the car key signal is detected, after receiving the first pressing signal and delaying for a first preset time, a door locking command is generated to control the door lock to switch from the unlocked state to the locked state.

[0020] Furthermore, the step of generating a handle unfolding command or a handle folding command after a second preset time delay based on the first pressing signal, the door handle state, and the door lock state, to control the door handle state switching, further includes:

[0021] If the door lock is in the locked state and the door handle is in the folded state, then when the car key signal is detected, no handle unfolding command will be generated after receiving the first pressing signal and delaying for a second preset time.

[0022] Secondly, embodiments of this application also provide a concealed door handle control system, including:

[0023] A door handle micro switch is used to accept pressure in the initial state and generate a first pressure signal after being pressed; the initial state is the current door lock state and door handle state.

[0024] A handle controller, communicatively connected to the door handle microswitch, is used to acquire the current door lock status and door handle status in real time; acquire the first pressing signal; detect the car key signal based on the first pressing signal; if the car key signal is detected, generate a door unlock command or a door lock command after a first preset time delay based on the first pressing signal and the door lock status, to control the door lock status switching; and generate a handle unfold command or a handle fold command after a second preset time delay based on the first pressing signal, the door handle status, and the door lock status, to control the door handle status switching; wherein the second preset time is greater than the first preset time.

[0025] The door lock motor is communicatively connected to the handle controller and is used to unlock or lock the door lock according to the door unlocking command or door locking command.

[0026] The handle motor is communicatively connected to the handle controller and is used to execute the unfolding or folding of the door handle according to the handle unfolding command or handle folding command.

[0027] In some embodiments, a door lock actuator is also included, wherein the output shaft of the door lock motor is connected to the input end of the door lock actuator, and is used to drive the latch of the door lock actuator to retract or extend when receiving the door unlocking command or the door locking command.

[0028] In some embodiments, the handle controller includes a car key detection module; the car key detection module is used to generate a detection signal of the car key signal when the first pressing signal is received.

[0029] In some embodiments, the handle controller further includes: a door lock status detection module, which is communicatively connected to the door lock motor, for acquiring the door lock status in real time; and a door handle status detection module, which is communicatively connected to the handle motor, for acquiring the door handle status in real time.

[0031] The beneficial technical effects of this application are:

[0032] The concealed door handle control method or system provided in this application generates a door unlocking command or a door locking command after a first preset time delay based on a first pressing signal and the door lock status. It also generates a handle unfolding command or a handle folding command after a second preset time delay based on the first pressing signal, the door handle status, and the door lock status. Since the second preset time is longer than the first preset time, it avoids the situation where pressing the door handle microswitch while the door is unlocked and the handle is folded results in an unfolding operation. The door handle unfolding or keyless locking function can be achieved with a single press of the microswitch, thereby reducing the number of presses required to lock the door and improving the user experience.

[0033] Additional aspects and advantages of this application will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of this application. Attached Figure Description

[0041] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present application.

[0042] like Figure 1 As shown in the figure, this application provides a concealed vehicle door handle control system, including: a door handle micro switch 100, a handle controller 200, a door lock motor 300, and a handle motor 400. The door handle micro switch 100, the door lock motor 300, and the handle motor 400 are all communicatively connected to the handle controller 200.

[0043] The door handle micro switch 100 is generally located on the side of the door handle facing outwards. It is used to accept pressure in the initial state and generate the first press signal after being pressed. The initial state is the current door lock state and door handle state.

[0044] The handle controller 200, as the core control component of the concealed door handle control system, is used to execute the following processes:

[0045] The system acquires the current door lock and door handle status in real time. It acquires the first press signal generated after the door handle microswitch 100 is pressed. Based on the first press signal, it detects the car key signal. If the car key signal is detected, it generates a door unlock or door lock command after a first preset time delay, based on the first press signal and the door lock status, to control the door lock status switching. Based on the first press signal, door handle status, and door lock status, it generates a handle unfold or handle fold command after a second preset time delay, to control the door handle status switching; wherein the second preset time is longer than the first preset time.

[0046] The door lock motor 300 is the driving component of the actuator for unlocking or locking the vehicle door. It is used to unlock the vehicle door lock according to the door unlocking command, or to lock the vehicle door lock according to the door locking command.

[0047] The handle motor 400 is the drive component of the actuator for unfolding or folding the door handle, used to unfold the door handle according to the handle unfolding command, or fold the door handle according to the handle folding command.

[0048] The concealed door handle control system of this application embodiment generates a door unlocking command or a door locking command after a first preset time delay based on a first pressing signal and the door lock status. It also generates a handle unfolding command or a handle folding command after a second preset time delay based on the first pressing signal, the door handle status, and the door lock status. Since the second preset time is longer than the first preset time, the door unlocking or locking command takes precedence over the handle unfolding or folding command. This avoids the situation where, in the initial state of the door being unlocked and the handle folded, pressing the door handle microswitch results in an unfolding operation. In other words, the door handle unfolding or keyless locking function is achieved with a single press of the microswitch, thereby reducing the number of presses required for the user to lock the door and improving the user experience.

[0049] Specifically, under normal circumstances, the door handle will be in the locked state when the car door is locked. Therefore, the initial states of the door handle and the car door mainly include three situations: the car door is locked and the door handle is folded, the car door is unlocked and the door handle is unfolded, and the car door is unlocked and the door handle is folded.

[0050] In the first scenario: After the user presses the door handle microswitch 100, a first press signal is generated. When the handle controller 200 obtains the initial state as the door is locked and the door handle is folded, it detects the car key signal based on the first press signal. If the handle controller 200 detects the car key signal, it generates a door unlocking command after a first preset time delay (e.g., 500 milliseconds) after receiving the first press signal. Upon receiving the door unlocking command, the door lock motor 400 unlocks the door, thus switching the door lock state from locked to unlocked. Since the door is unlocked, after receiving the first press signal, the handle controller 200 generates a handle unfolding command after a second preset time delay (e.g., 600 milliseconds). Upon receiving the handle unfolding command, the handle motor 400 unfolds the handle, thus switching the handle state from folded to unfolded. In other words, the door unlocking and door handle unfolding can be achieved with a single press of the door handle microswitch.

[0051] The second scenario: After the user presses the door handle microswitch 100, a first press signal is generated. When the handle controller 200 obtains the initial state as unlocked and the door handle unfolded, it detects the car key signal based on the first press signal. If the handle controller 200 detects the car key signal, it generates a door locking command after a first preset time (e.g., 500 milliseconds). Upon receiving the door locking command, the door lock motor 300 executes the door locking, thereby switching the door lock state from unlocked to locked. Since the door is in the locked state, the handle controller 200 generates a handle folding command after a second preset time (e.g., 600 milliseconds). Upon receiving the handle folding command, the handle motor 400 folds the handle, thereby switching the handle state from unfolded to folded. In other words, door locking and door handle folding can be achieved with a single press of the door handle microswitch.

[0052] The third scenario: After the user presses the door handle microswitch 100, a first press signal is generated. When the handle controller 200 obtains the initial state as unlocked and the door handle folded, it detects the car key signal based on the first press signal. If the handle controller 200 detects the car key signal, it generates a door locking command after a first preset time (e.g., 500 milliseconds). Upon receiving the door locking command, the door lock motor 300 executes the door locking, thus switching the door lock state from unlocked to locked. Since the door is in the locked state, the handle controller 200 does not generate a handle unfolding command, and the door handle remains folded. Because the execution time of the door locking logic takes precedence over the door handle unfolding control logic, and it is necessary to simultaneously determine whether the door lock state is unlocked; otherwise, the handle unfolding command will not be executed. Therefore, the situation where pressing the microswitch results in the handle unfolding being executed first will not occur.

[0053] It should be noted that the car key signal is the radio wave signal emitted by the car key, which can be recognized by the car antenna within a certain distance range. When the radio wave signal is recognized, the door handle micro switch is triggered to perform the corresponding door unlocking or door locking actions.

[0054] Optionally, the handle controller 200 can be integrated into the body controller, and the body controller can execute the corresponding process.

[0055] In some embodiments, such as Figure 2 As shown, the concealed door handle control system includes a door handle micro switch 100, a handle controller 200, a door lock motor 300, and a handle motor 400, as well as a door lock actuator 500. The output shaft of the door lock motor 300 is connected to the input end of the door lock actuator 500, and is used to retract or extend the latch of the door lock actuator when a door unlocking or locking command is received.

[0056] Specifically, the door lock motor 300 is the driving component for unlocking or locking the vehicle door, and the unlocking or locking of the vehicle door is actually performed by the door lock actuator 500. The door lock actuator 500 has a conventional vehicle door lock structure. The output shaft of the door lock motor 300 is connected to the input end (or input shaft) of the door lock actuator 500. When the door lock motor 300 receives an unlocking or locking command sent by the handle controller 200, it executes the forward or reverse rotation of the door lock motor 300, thereby driving the latch of the door lock actuator 500 to retract or extend, thus realizing the unlocking or locking of the vehicle door.

[0057] Optionally, please continue reading Figure 2 The concealed door handle control system, in addition to the door handle micro switch 100, handle controller 200, door lock motor 300, handle motor 400, and door lock actuator 500, also includes a handle actuator 600. The handle actuator 600 can adopt an existing concealed door handle unfolding and folding mechanism. The input end of the handle actuator 600 is connected to the output end (shaft) of the handle motor 400. The forward and reverse rotation of the handle motor 400 changes the state of the handle actuator 600, thereby driving the door handle to unfold or fold.

[0058] In some embodiments, such as Figure 3 As shown, the handle controller 200 also includes a car key detection module 210; the car key detection module 210 is used to generate a detection signal for the car key signal when a first pressing signal is received.

[0059] Specifically, whether the first press signal is received (whether the door handle microswitch is touched) can be considered as the trigger condition for the car key detection module 210 to generate the detection signal. That is, if the door handle microswitch 100 is not triggered, even if the car key detection module 210 detects the car key signal, it will still not trigger the detection signal. This detection signal determines whether to generate a door unlock or lock command. Therefore, the car key detection module 210 needs to recognize the first press signal before it can generate the car key signal detection signal. This detection signal can generate a door unlock or lock command after recognizing the car key signal.

[0060] Optionally, the car key detection module 210 can also be a separate control module within the body controller, as long as it can generate a detection signal for the car key signal when the first press signal is received.

[0061] In some embodiments, such as Figure 4As shown, in order to enable the handle controller 200 to acquire the door lock status and door handle status in real time, the handle controller 200 also includes: a door lock status detection module 220 and a door handle status detection module 230. The door lock status detection module 220 is communicatively connected to the door lock motor 300 and is used to acquire the door lock status in real time; the door handle status detection module 230 is communicatively connected to the handle motor 400 and is used to acquire the door handle status in real time.

[0062] Specifically, the door lock status detection module 220 is communicatively connected to the door lock motor 300. Based on the rotation position of the door lock motor 300, it can acquire the door lock status in real time. This allows the handle controller 200 to determine the door status switching command (unlock or lock) generated after receiving the car key signal, based on the current door lock status. Furthermore, the door handle status detection module 230 is communicatively connected to the handle motor 400. Based on the rotation position of the handle motor 400, it can acquire the door handle status in real time. This allows it to determine the handle status switching command (fold or unfold) generated after receiving the car key signal, based on both the door lock status and the door handle status.

[0063] Based on the same inventive concept, such as Figure 5 As shown, this application embodiment also provides a method for controlling a concealed car door handle, including the following steps S101 to S105:

[0064] S101, obtains the current door lock status and door handle status in real time.

[0065] Specifically, the switching of door status and handle status are based on the current door lock status and door handle status. Therefore, it is necessary to obtain the current door lock status and door handle status in real time in order to generate the corresponding switching command in a timely manner.

[0066] S102, acquire the first press signal of the door handle micro switch in the initial state; the initial state is the current door lock state and door handle state.

[0067] Specifically, since the door handle is in the locked state when the door is locked, there is no initial state where the door is locked and the handle is unfolded. Therefore, the initial door lock and handle states mainly fall into three categories: door locked and handle folded, door unlocked and handle unfolded, and door unlocked and handle folded. For each of these three initial states, pressing the door handle microswitch generates the corresponding first press micro-signal.

[0068] S103, based on the first press signal, detects the car key signal.

[0069] Specifically, after the handle controller generates the first micro-motion signal, it first needs to determine whether a car key signal has been detected. Based on the initial state of the door and whether a car key signal has been detected, it determines whether to generate the corresponding door unlock or lock command.

[0070] S104, if a car key signal is detected, a door unlocking command or a door locking command is generated after a first preset time delay based on the first pressing signal and the door lock status, so as to control the switching of the door lock status.

[0071] Specifically, when a car key signal is detected, after receiving the first press signal and delaying for a first preset time, a corresponding door unlock command or door lock command is generated based on the initial door lock state (before pressing the door handle microswitch). If the initial door lock state is unlocked, a door lock command is generated after the first preset time, thereby switching the door lock state from unlocked to locked; if the initial door lock state is locked, a door unlock command is generated after the first preset time, thereby switching the door lock state from locked to unlocked.

[0072] It should be noted that if the car key signal is not detected, no door unlock or door lock command will be generated.

[0073] S105, based on the first pressing signal, the door handle status, and the door lock status, after a second preset time delay, a handle unfolding command or a handle folding command is generated to control the door handle status switching; wherein, the second preset time is greater than the first preset time.

[0074] Specifically, after executing the door unlock or door lock command, the handle controller continues to determine whether to generate a corresponding handle unfold or handle fold command based on the received first press signal, the current door handle state, and the door lock state. It should be noted that if the door lock command is executed and the door state is switched to locked, no handle unfold command will be generated.

[0075] It should be noted that step S101 is not limited to before step S102. Step S101 can be executed in real time throughout the entire method flow. For example, it can be before step S103, or before step S104, or before step S105.

[0076] The concealed door handle control method provided in this application generates a door unlocking command or a door locking command after a first preset time delay based on a first pressing signal and the door lock status. Furthermore, it generates a handle unfolding command or a handle folding command after a second preset time delay based on the first pressing signal, the door handle status, and the door lock status. Since the second preset time is longer than the first preset time, it avoids the situation where pressing the door handle microswitch in the unlocked state results in a handle unfolding operation. The door handle unfolding or keyless locking functions can be achieved with a single press of the microswitch, thereby reducing the number of presses required for the user to lock the door and improving the user experience.

[0077] Furthermore, given that the keyless unlocking and handle unfolding share the same door handle microswitch, the control logic for keyless unlocking and handle unfolding can be executed separately, thus avoiding the instability of the control system caused by complex control logic.

[0078] In some embodiments, step S103 specifically includes: generating a detection signal for the car key signal when a first pressing signal is received.

[0079] Specifically, the first press signal (whether the door handle microswitch is touched) can be seen as the trigger condition for the car key detection module to generate a detection signal. That is, if the door handle microswitch is not triggered, even if the car key detection module detects the car key signal, it will not trigger the detection signal. This detection signal determines whether to generate a door unlock or lock command. Therefore, the car key detection module needs to recognize the first press signal before it can generate the car key signal detection signal. Once the car key signal is recognized, the detection signal can generate a door unlock or lock command.

[0080] In some embodiments, step S104 in the above embodiments specifically includes:

[0081] If the door lock is in the locked state and the door handle is in the folded state, when the car key signal is detected, after receiving the first press signal and delaying for a first preset time, a door unlocking command is generated to control the door lock to switch from the locked state to the unlocked state.

[0082] Specifically, after the user presses the microswitch on the door handle, a first press signal is generated. When the initial state acquired by the handle controller is that the door is locked and the door handle is folded, the car key signal is detected based on the first press signal. If the handle controller detects the car key signal, it generates a door unlocking command after a first preset time delay (e.g., 500 milliseconds) after receiving the first press signal. After receiving the door unlocking command, the door lock motor executes the door unlocking, thereby switching the door lock state from locked to unlocked.

[0083] If the door lock is unlocked and the door handle is extended, when the car key signal is detected, a door locking command is generated after receiving the first press signal and delaying for a first preset time, which is used to control the door lock to switch from the unlocked state to the locked state.

[0084] Specifically, after the user presses the microswitch on the door handle, a first press signal is generated. When the initial state acquired by the handle controller is that the door is unlocked and the door handle is unfolded, the car key signal is detected based on the first press signal. If the handle controller detects the car key signal, it generates a door locking command after a first preset time (e.g., 500 milliseconds). Upon receiving the door locking command, the door lock motor executes the door locking, thereby switching the door lock state from unlocked to locked.

[0085] In some embodiments, step S105 in the above embodiments specifically includes:

[0086] If the door lock is unlocked and the door handle is folded, a handle unfolding command is generated after receiving the first pressing signal and delaying for a second preset time, which is used to control the door handle to switch from the folded state to the unfolded state.

[0087] Specifically, since the car door is in the unlocked state, after receiving the first press signal, the handle controller generates a handle unfolding command after a second preset time (e.g., 600 milliseconds). After receiving the handle unfolding command, the handle motor unfolds the handle, thereby switching the handle state from folded to unfolded. That is, the car door can be unlocked and the door handle can be unfolded by pressing the door handle micro switch once.

[0088] If the door lock is locked and the door handle is extended, a handle folding command is generated after receiving the first pressing signal and delaying for a second preset time, which is used to control the door handle to switch from the extended state to the folded state.

[0089] Specifically, since the car door is in the locked state, the handle controller generates a handle folding command after a second preset time (e.g., 600 milliseconds). After receiving the handle folding command, the handle motor folds the handle, thereby switching the handle state from unfolded to folded. That is, the car door can be locked and the door handle can be folded by pressing the door handle micro switch once.

[0090] In some embodiments, step S104 in the above embodiments further includes:

[0091] If the door lock is unlocked and the door handle is folded, when the car key signal is detected, a door locking command is generated after receiving the first press signal and delaying for a first preset time, which is used to control the door lock to switch from the unlocked state to the locked state.

[0092] Furthermore, step S105 in the above embodiments further includes:

[0093] If the door lock is locked and the door handle is folded, when the car key signal is detected, no handle unfolding command will be generated after receiving the first press signal and delaying for a second preset time.

[0094] Specifically, after the user presses the microswitch on the door handle, a first press signal is generated. When the initial state acquired by the handle controller is that the door is unlocked and the door handle is folded, the car key signal is detected based on the first press signal. If the handle controller detects the car key signal, it generates a door locking command after a first preset time (e.g., 500 milliseconds). Upon receiving the door locking command, the door lock motor executes the door locking, thereby switching the door lock state from unlocked to locked. Since the door is in the locked state, the handle controller does not generate a handle unfolding command, and the door handle remains in the folded state.

[0095] Figure 6 A flowchart illustrating the execution of a concealed door handle control method is provided, as follows: Figure 6 As shown, at the start of the process, firstly, the door handle microswitch needs to be pressed, generating a first press signal. Then, the car key signal is detected. If the car key signal is detected, the door lock motor performs a keyless door unlocking or locking action after a first preset time delay (e.g., 500 milliseconds). If no car key signal is detected, the process ends. Next, after a second preset time (e.g., 600 milliseconds), it is determined whether the door lock is unlocked. If the door lock is unlocked, the process continues to determine whether the door handle is folded. If the door lock is locked, the process ends (no unfolding command is generated). Finally, if the door handle is folded, a door handle unfolding command is generated, and the handle motor performs the corresponding door handle unfolding action.

[0096] Based on the same inventive concept, this application also provides a vehicle including the aforementioned hidden door handle control system described in this application.

[0097] The vehicle provided in this application embodiment includes the aforementioned hidden door handle control system of this application embodiment. The hidden door handle control system generates a door unlock command or a door lock command after a first preset time delay based on a first press signal and door lock status. It also generates a handle unfold command or handle fold command after a second preset time delay based on the first press signal, door handle status, and door lock status. Since the second preset time is longer than the first preset time, it avoids the situation where the door handle micro switch is pressed when the door is unlocked, but the handle unfolding operation is performed. The door handle unfolding or keyless locking function can be achieved by pressing the micro switch once, thereby reducing the number of times the user presses the button to lock the door and improving the user experience.

[0098] The above embodiments of this application have at least the following beneficial effects:

[0099] 1. Based on the first press signal and the door lock status, a door unlock command or door lock command is generated after a first preset time delay. Based on the first press signal, door handle status, and door lock status, a handle unfold command or handle fold command is generated after a second preset time delay. Since the second preset time is longer than the first preset time, the situation where the door handle microswitch is pressed when the door is unlocked is avoided, and the door handle unfolding or keyless locking functions can be achieved by pressing the microswitch once, thereby reducing the number of times the user needs to press to lock the door and improving the user experience.

[0100] 2. Under the premise that the keyless unlocking and handle unfolding share the same door handle micro switch, the control logic of keyless unlocking and handle unfolding can be executed separately, thereby avoiding the problem of instability of the control system caused by complex control logic.

[0101] 3. When the handle controller receives the initial state of the door being locked and the door handle being folded, it detects the car key signal based on the first press signal. If the handle controller detects the car key signal, it generates a door unlocking command after a first preset time delay following the first press signal. Upon receiving the door unlocking command, the door lock motor unlocks the door, thus switching the door lock state from locked to unlocked. Since the door is unlocked, the handle controller generates a handle unfolding command after a second preset time delay following the first press signal. Upon receiving the handle unfolding command, the handle motor unfolds the handle, thus switching the handle state from folded to unfolded. In other words, the door unlocking and door handle unfolding can be achieved with a single press of the door handle microswitch.

[0102] 4. After the user presses the door handle microswitch, a first press signal is generated. When the initial state acquired by the handle controller is that the door is unlocked and the door handle is unfolded, the car key signal is detected based on the first press signal. If the handle controller detects the car key signal, it generates a door locking command after a first preset time delay. Upon receiving the door locking command, the door lock motor executes the door locking, thereby switching the door lock state from unlocked to locked. Since the door is in the locked state, the handle controller generates a handle folding command after a second preset time delay. Upon receiving the handle folding command, the handle motor folds the handle, thereby switching the handle state from unfolded to folded. That is, the door locking and door handle folding can be achieved with a single press of the door handle microswitch.

[0103] 5. After the user presses the microswitch on the door handle, a first press signal is generated. When the initial state acquired by the handle controller is that the door is unlocked and the door handle is folded, the car key signal is detected based on the first press signal. If the handle controller detects the car key signal, it generates a door locking command after a first preset time delay. Upon receiving the door locking command, the door lock motor executes the door locking, thereby switching the door lock state from unlocked to locked. Since the door is in the locked state, the handle controller does not generate a handle unfolding command, and the door handle remains in the folded state.
