Description

Technical Field

[0001] This invention relates to the field of door handle control technology, and more particularly to a door handle control method, device, equipment, and vehicle. Background Technology

[0002] Current vehicles' retractable power door handles, when extended for a certain period, or when the key is detected to have moved a certain distance away, or after receiving a locking command from the key, will first detect whether there is an obstacle between the door handle and the door. If an obstacle is present, the handle will remain in its maximum extended position for a certain period to achieve the anti-pinch function. However, the anti-pinch function may be falsely triggered during execution, causing the door handle to fail to retract, affecting the vehicle's locking action and resulting in a poor user experience. Summary of the Invention

[0003] This invention provides a door handle control method, device, equipment, and vehicle, which solves the technical problem that the anti-pinch function of the existing hidden door handle can only achieve simple anti-pinch by keeping the door handle in the extended state, without a prompt function, and there is a technical problem that the door handle cannot be retracted due to accidental triggering during the anti-pinch process.

[0004] In a first aspect, embodiments of the present invention provide a method for controlling a door handle, the method comprising:

[0005] Receive the retraction request of the target door handle;

[0006] In response to an obstacle detection signal from the target door handle, the target door handle is controlled to perform an anti-pinch warning action;

[0007] In response to the absence of the obstacle sensing signal on the target door handle, the target door handle is controlled to perform a corresponding operation based on the number of retraction attempts. The number of retraction attempts is accumulated based on the number of times the obstacle sensing signal is triggered during the execution of the retraction request. The obstacle sensing signal is used to characterize whether there is an obstacle between the door handle and the door. The corresponding operation includes a full retraction action and an attempt to retract action.

[0008] Secondly, embodiments of the present invention also provide a door handle control device, the control device comprising:

[0009] The signal receiving unit is used to receive the retraction request of the target door handle;

[0010] The anti-pinch reminder unit is used to control the target door handle to perform an anti-pinch reminder action in response to an obstacle detection signal from the target door handle.

[0011] A handle control unit is configured to control the target door handle to perform a corresponding operation based on the number of retraction attempts in response to the absence of the obstacle sensing signal. The number of retraction attempts is accumulated based on the number of times the obstacle sensing signal is triggered during the execution of the retraction request. The obstacle sensing signal is used to characterize whether there is an obstacle between the door handle and the door.

[0012] Thirdly, embodiments of the present invention also provide an electronic device, the electronic device comprising:

[0013] At least one processor; and

[0014] A memory communicatively connected to the at least one processor; wherein,

[0015] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the door handle control method described in the first aspect above.

[0016] Fourthly, embodiments of the present invention also provide a vehicle, the vehicle including a door handle control device as described in the second aspect above or an electronic device as described in the third aspect above.

[0017] This invention discloses a door handle control method, device, equipment, and vehicle. The control method includes: receiving a retraction request from a target door handle; responding to an obstacle sensing signal on the target door handle, controlling the target door handle to perform an anti-pinch warning action; responding to the absence of an obstacle sensing signal on the target door handle, controlling the target door handle to perform a corresponding operation based on the number of retraction attempts, the corresponding operation including a full retraction action and a retraction attempt action, wherein the number of retraction attempts is accumulated based on the number of times the obstacle sensing signal is triggered during the execution of the retraction request, and the obstacle sensing signal is used to characterize whether there is an obstacle between the door handle and the door. This invention detects the presence of obstacles at the door handle. If an obstacle is present, the door handle is controlled to provide an anti-pinch warning to the user. If no obstacle is present, the door handle's action is controlled based on the number of retraction attempts. This solves the technical problems of existing concealed door handles, which only provide simple anti-pinch protection by keeping the door handle in an extended state without a warning function, and are prone to accidental triggering during the anti-pinch process, causing the door handle to fail to retract. This invention achieves the technical effects of providing anti-pinch warnings to the user, effectively reducing the risk of the door handle pinching the user's hand, avoiding the impact on the vehicle's locking action due to accidental triggering of the anti-pinch function, and improving the user experience.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish different objects, not to limit a specific order. The various embodiments of this invention described below can be performed individually or in combination with each other; the embodiments of this invention do not impose specific limitations in this regard.

[0027] For vehicles with concealed door handles, the handles only extend when needed. In most situations, to reduce driving resistance and maintain a clean and aesthetically pleasing door design, the handles are retracted and kept flush with the door. However, the retraction process can easily trap a hand. Therefore, before retracting, the door handle detects any foreign objects between the handle and the door to prevent pinching. However, when a foreign object is detected, the handle is usually kept in the extended position for a certain period before another check. This presents a problem: if the detection device is accidentally triggered, the handle will continuously detect the presence of a foreign object and remain extended, affecting the vehicle's locking mechanism and resulting in a poor user experience.

[0028] Figure 1This is a flowchart of a door handle control method provided in an embodiment of the present invention.

[0029] like Figure 1 As shown, the control method for this door handle specifically includes the following steps:

[0030] S101, Receive the retraction request of the target door handle.

[0031] In some embodiments, the target door handle refers to the door handle among multiple door handles of a vehicle that receives the retraction request. The retraction request can be a locking command issued by the car key, an automatically generated locking command when the car key is detected to be a distance away from the vehicle, a retraction request generated after the door handle has been extended for a set duration, or a locking command generated when the door needs to perform a locking action when the vehicle starts moving; no specific limitations are imposed here. After receiving the retraction request from the target door handle, the controller detects whether there is an obstacle at the target door handle using corresponding sensors and generates an obstacle sensing signal based on the detection result. The controller can be a vehicle controller, a door handle controller, etc., and the obstacle sensing signal can be set as a current signal, voltage signal, capacitance signal, or any other electrical signal that can indicate the presence of an obstacle at the door handle.

[0032] S102, in response to the obstacle detection signal of the target door handle, controls the target door handle to perform an anti-pinch warning action.

[0033] In some embodiments, if an obstacle sensing signal is detected, the target door handle is controlled to perform actions that can prompt the user, so that the user will remove their hand from the door handle after receiving these prompts, thereby preventing pinching.

[0034] For example, the obstacle sensing signal can be a signal generated by the triggering of the internal capacitor at the door handle, or it can be other electrical signals that can detect obstacles at the door handle. Taking the capacitance signal as an example, when there is no obstacle between the door handle and the door, the distance between the two conductors, the door handle and the door, is relatively stable, that is, the distance between the two plates of the capacitor is relatively stable, and the capacitance value remains unchanged. When the user places their hand between the handle of the concealed door and the door, the insertion of the hand changes the distance between the two conductors, thus changing the capacitance value of the internal capacitor. This change in capacitance value triggers the internal capacitor at the door handle. The capacitance signal of the internal capacitor whose capacitance value has changed can be collected by the capacitance sensor installed at the door handle, which is the obstacle sensing signal. When the controller receives a request to retract the door handle, it first determines whether the internal capacitor at the target door handle has been triggered, that is, whether there is an obstacle sensing signal. The controller can be the vehicle controller or the door handle controller, etc.

[0035] In some embodiments, the obstacle sensing signal is obtained using a capacitive sensor located at the target door handle.

[0036] Specifically, since the internal capacitor and capacitance sensor at the door handle are used to realize the keyless door opening and closing function, the capacitance signal can be used as the obstacle sensing signal. There is no need to add corresponding devices. Only the internal capacitor and capacitance sensor set in the vehicle itself are needed, which can save costs, reduce the space occupied by the devices, and has greater universality.

[0037] Optionally, the anti-pinch warning action includes at least one of the following: immediately extending after retracting to a preset distance, emitting a warning sound, flashing a warning light, or other actions or displays that can provide a warning to the user.

[0038] Specifically, the door handle extends immediately after retracting a preset distance. This action actually feels like a slight vibration to the user, indicating that the target door handle is about to retract, thus achieving the anti-pinch function. It can also emit a prompting sound, such as "the handle is about to retract," or a simple "beep" sound, when an obstacle is detected. The prompting sound can be customized by the user. Finally, a flashing indicator light can be installed on the door handle to alert the user as needed.

[0039] Alternatively, through extensive research, the inventors have discovered that the anti-pinch warning action includes retracting the handle to a preset distance before extending it. The preset distance is 8%-20% of the target door handle's extension distance. This not only allows the user to perceive the handle and serves as a warning, but also prevents the handle from retracting excessively and causing the user's hand to be pinched.

[0040] Specifically, since issuing a warning sound requires the use of an additional voice broadcasting device, and flashing warning lights require the use of an additional light source device, these devices may be devices that are already present in the vehicle, or they may be additionally installed at the door as needed. Therefore, it is preferable to use an anti-pinch warning action that extends immediately after retracting a preset distance. No additional functional devices are needed, and the door handle itself can be used to remind the user of the anti-pinch action.

[0041] The preset distance setting is based on the distance at which the target door handle can alert the user through action without pinching the user's hand. Therefore, the preset percentage of the target door handle's extension distance can be determined as needed, such as 8%-20%, so that the door handle can be extended immediately after retracting the preset distance to provide an anti-pinch alert.

[0042] For example, when the preset percentage is set to 8% of the door handle extension distance, this distance is the minimum distance that can both avoid pinching the user's hand and provide a slight "shaking" warning to the user. Using this distance can reduce the action time of the anti-pinch warning action. When the preset percentage is set to 20% of the door handle extension distance, this distance allows the user to clearly perceive that the door handle is retracting inward, making the anti-pinch warning more significant. Preferably, the preset distance can be set to 10% of the distance from the hidden state to the fully extended state of the door handle. At a 10% extension distance, on the one hand, the user can clearly perceive that the door handle is about to retract, and on the other hand, the time left for the anti-pinch warning action will not be too long, affecting the door locking time.

[0043] S103, in response to the absence of an obstacle sensing signal on the target door handle, the target door handle is controlled to perform a corresponding operation based on the number of retraction attempts. The number of retraction attempts is obtained by accumulating the number of times the obstacle sensing signal is triggered during the retraction request. The obstacle sensing signal is used to characterize whether there is an obstacle between the door handle and the door. The corresponding operations include a full retraction action and an attempt to retract action.

[0044] In some embodiments, if no obstacle sensing signal is detected, the target door handle is driven to retract. During this process, it is also necessary to determine whether the number of attempts to retract the target door handle has reached a preset threshold. To implement the anti-pinch function of the target door handle, a preset number of retraction attempts are given to the target door handle. That is, when the target door handle attempts to retract, if an obstacle sensing signal is detected, the target door handle is kept in the extended position, and the number of attempts to retract is incremented by 1 until the number of attempts to retract reaches the preset threshold, at which point the target door handle is driven to retract.

[0045] It should be noted that in step S101, when the retraction request of the door handle is received for the first time, the number of attempts to retract the target door handle is recorded as 0, and then the process of the target door handle retracting the request is executed.

[0046] In some embodiments, the preset number of attempts threshold can be set to 2, meaning the target door handle can attempt to retract twice to prevent the risk of being pinched. It should be noted that the preset number of attempts threshold can also be customized according to the needs of different vehicle models and usage scenarios; no specific restrictions are imposed here.

[0047] This invention detects whether there is an obstacle at the door handle. If an obstacle is present, the door handle is controlled to provide an anti-pinch reminder to the user. If no obstacle is present, the door handle is controlled based on the number of attempts to retract. This solves the technical problem that the anti-pinch function of existing hidden door handles can only achieve simple anti-pinch by keeping the door handle in an extended state, without a reminder function. This invention achieves the technical effect of providing anti-pinch reminders to the user, effectively reducing the risk of the door handle pinching the user's hand, and not affecting the vehicle's locking action.

[0048] In some embodiments, S103 may include:

[0049] In response to an attempt to retract the door handle exceeding a preset threshold, the target door handle is fully retracted.

[0050] In response to a number of attempts to retract being less than or equal to a preset threshold, the door handle is controlled to perform either an attempt to retract or a complete retraction action based on whether an obstacle sensing signal exists on the target door handle.

[0051] The retraction attempt can involve retracting the door handle a predetermined distance while simultaneously detecting an obstacle sensor signal. If no obstacle sensor signal is detected, the door handle continues retracting after the predetermined distance until it is fully retracted. If an obstacle sensor signal is detected, the door handle stops retracting after the predetermined distance and then extends to its maximum extension position to achieve the anti-pinch function. The predetermined distance can be set as needed, ensuring that it does not pose a risk of pinching obstacles between the door handle and the door. In one optional implementation, the predetermined distance can be set to 8%-20% of the door handle's extension distance.

[0052] Figure 2 This is a flowchart of another door handle control method provided in an embodiment of the present invention, specifically, as follows: Figure 2 As shown, taking the obstacle sensing signal as a capacitance signal as an example, when there is no obstacle sensing signal on the target door handle, S201 is first executed to obtain the number of attempts to retract the target door handle currently recorded, and S202 is executed to determine whether the number of attempts to retract is greater than a preset threshold. If the determination result is that the number of attempts to retract is greater than or equal to the preset threshold, then S203 is executed directly to control the target door handle to retract completely; if the determination result is that the number of attempts to retract is less than or equal to the preset threshold, then it is necessary to detect whether the internal capacitance of the target door handle is triggered, that is, to detect whether there is an obstacle sensing signal on the target door handle, and S204 is executed to control the door handle to perform an attempt to retract or a complete retraction action based on whether there is an obstacle sensing signal on the target door handle.

[0053] In some embodiments, Figure 3 This is a flowchart of another door handle control method provided in an embodiment of the present invention, such as... Figure 3 As shown, S204 may include:

[0054] In response to the obstacle detection signal of the target door handle, control the target door handle to perform a full retraction action;

[0055] In response to an obstacle detection signal from the target door handle, the target door handle is kept in its maximum extended position, and an attempt to retract is made at a first preset time interval.

[0056] Specifically, when the number of retraction attempts is less than or equal to a preset threshold, S501 is first executed to determine whether there is an obstacle sensing signal on the target door handle. If the result is that there is no obstacle sensing signal, it means that there is no obstacle between the target door handle and the door, and the target door handle can be retracted directly, i.e., S502 is executed to control the door handle to complete the retraction action. If the result is that there is an obstacle sensing signal, S503 is executed to control the target door handle to remain in the maximum extended position to achieve the anti-pinch function, and the number of retraction attempts is incremented by 1, indicating that the target door handle has been controlled to attempt retraction once. Then, S504 is executed to wait for a first preset time, and then the door handle is controlled to perform the corresponding action again according to the number of retraction attempts.

[0057] It should be noted that the first preset duration can be customized as needed. The first preset duration should not be too long, otherwise it will increase the waiting time for the door handle to retract, affecting the user experience. Preferably, the first preset duration is 2 seconds.

[0058] After waiting for the first preset time, the number of attempts to retract the target door handle is obtained again, and it is determined whether the number exceeds the preset threshold until the target door handle can be directly controlled to perform a full retraction action.

[0059] Based on the above technical solutions, Figure 4 This is a flowchart of another door handle control method provided in an embodiment of the present invention, such as... Figure 4 As shown, after S102, the control method further includes:

[0060] S401, determine whether there is an obstacle sensing signal on the target door handle at a second preset time interval.

[0061] S402, in response to the absence of an obstacle sensing signal on the target door handle after a second preset time interval, control the target door handle to perform a retraction action; in response to the presence of an obstacle sensing signal on the target door handle after a second preset time interval, execute S103 to control the target door handle to perform a corresponding operation based on the number of retraction attempts.

[0062] Specifically, after the target door handle performs an anti-pinch warning action and provides the first reminder to the user, a second preset time interval is elapsed to determine if the target door handle has an obstacle detection signal, i.e., to detect whether the user has removed their hand from the target door handle. If no obstacle detection signal is detected at this time, it indicates that the user has removed their hand from the target door handle, and the target door handle can be controlled to retract. The second preset time interval can be customized as needed, but it must ensure that the user has sufficient reaction time to retract their hand. Preferably, the second preset time interval is 10 seconds.

[0063] If an obstacle sensing signal is still detected at this time, the target door handle is controlled to execute S103 based on the number of retraction attempts. This achieves secondary anti-pinch protection and avoids the possibility of false triggering of the internal capacitor or a malfunction of the capacitor sensor, which could cause the target door handle to continuously display an obstacle sensing signal for a second preset time period, thus affecting the retraction action.

[0064] Optionally, the control method further includes: if a new retraction request is received while the target door handle is executing a retraction request, then the new retraction request is not responded to.

[0065] Specifically, if the vehicle controller receives another retraction request while the target door handle is executing a retraction request, the new retraction request will not be executed. The number of retraction attempts will not be recorded as 0 due to the receipt of a new retraction request, thus not affecting the execution of the previous retraction request.

[0066] Optionally, the control method further includes: if a request to extend the door handle is received when the target door handle is making a retraction request, the action of making the retraction request is immediately terminated, and the extension request is made after a third preset time interval.

[0067] Specifically, if the vehicle controller receives a door handle extension request while executing a retraction request—for example, if a user needs to unlock the door and get in the vehicle while the door handle retracts—the retraction request action is immediately stopped, and the door handle extension request is executed after a third preset time interval. The third preset time interval can be customized as needed. This is because if the motor is rotating forward to control the door handle retraction and then suddenly reverses to control the door handle extension based on a received extension request, such a sudden reversal can damage the motor and affect its lifespan. Therefore, a protection time is needed to allow the motor to stop and then reverse.

[0068] In one optional implementation, the third preset duration can be set to 0s, but in order to protect the motor, the third preset duration is preferably set to 200ms.

[0069] Figure 5This is a structural diagram of a door handle control device provided in an embodiment of the present invention.

[0070] like Figure 5 As shown, the control device for the door handle specifically includes:

[0071] The signal receiving unit 51 is used to receive the retraction request of the target door handle;

[0072] The anti-pinch reminder unit 52 is used to control the target door handle to perform an anti-pinch reminder action in response to an obstacle sensing signal that the target door handle has an obstacle.

[0073] The handle control unit 53 is used to control the target door handle to perform corresponding operations in response to the obstacle-free sensing signal of the target door handle, based on the number of attempts to retract. The number of attempts to retract is obtained by accumulating the number of times the obstacle sensing signal is triggered during the execution of the retraction request. The obstacle sensing signal is used to characterize whether there is an obstacle between the door handle and the door.

[0074] Optionally, the handle control unit 53 is also used for:

[0075] In response to an attempt to retract the door handle exceeding a preset threshold, the target door handle is fully retracted.

[0076] In response to a number of attempts to retract being less than or equal to a preset threshold, the door handle is controlled to perform either an attempt to retract or a complete retraction action based on whether an obstacle sensing signal exists on the target door handle.

[0078] In response to the obstacle detection signal of the target door handle, control the target door handle to perform a full retraction action;

[0079] In response to an obstacle detection signal from the target door handle, the target door handle is kept in its maximum extended position, and an attempt to retract is made at a first preset time interval.

[0080] Optionally, after the anti-pinch reminder unit 52 controls the target door handle to perform the anti-pinch reminder action, the handle control unit 53 is further configured to:

[0081] In response to the absence of an obstacle sensing signal in the target door handle after a second preset time interval, the target door handle is controlled to retract.

[0082] In response to an obstacle detection signal on the target door handle after a second preset time interval, the target door handle is controlled to perform corresponding operations based on the number of attempts to retract.

[0083] Optionally, the signal determination unit 51 is also used for:

[0084] If the anti-pinch reminder unit 52 or the handle control unit 53 receives a new retraction request while controlling the target door handle to execute the retraction request, it will not respond to the new retraction request.

[0085] Optionally, the signal determination unit 51 is also used for:

[0086] If the anti-pinch reminder unit 52 or the handle control unit 53 receives a door handle extension request while controlling the target door handle to execute the door handle retraction request, the anti-pinch reminder unit 52 or the handle control unit 53 immediately stops executing the door handle retraction request, and the handle control unit 53 executes the door handle extension request at a third preset time interval.

The components of the system can be interconnected via digital data communication of any form or medium (e.g., communication networks). Examples of communication networks include local area networks (LANs), wide area networks (WANs), blockchain networks, and the Internet.

[0098] A computing system can include clients and servers. Clients and servers are generally located far apart and typically interact through communication networks. The client-server relationship is created by computer programs running on the respective computers and having a client-server relationship with each other. The server can be a cloud server, also known as a cloud computing server or cloud host, which is a hosting product within the cloud computing service system to address the shortcomings of traditional physical hosts and VPS services, such as high management difficulty and weak business scalability.

[0099] This invention also provides a vehicle that includes a door handle control device as described in any of the above embodiments or a door handle control equipment as described in any of the above embodiments.

[0100] Specifically, taking the control device of a vehicle, including the door handle, as an example, the door handle control device can be a separate control device, which controls the door handle under the control of the vehicle controller. On the one hand, there can be multiple control devices, with one control device controlling one door handle on one door. On the other hand, the number of control devices can be less than the number of door handles, setting it as a one-to-many control mode. The door handle control device can also be integrated into the vehicle controller, and the vehicle controller can directly control the door handle. No specific restrictions are made here.

[0101] For example, Figure 7 This is a diagram of the door handle control structure for a vehicle with four doors, provided in an embodiment of the present invention.

[0102] Optionally, the door handle control device is set independently, such as Figure 7 As shown, the vehicle includes a control device for four door handles, as well as four door handles, four capacitive sensors, and a vehicle controller.

[0103] Four control devices are installed one-to-one on each door handle, with each control device controlling the extension and retraction of one door handle.

[0104] Four capacitive sensors are installed one-to-one at each door handle, with each capacitive sensor acquiring an obstacle detection signal for one door handle.

[0105] All four control devices and four capacitive sensors are electrically connected to the vehicle controller.

[0106] Each capacitive sensor transmits the obstacle sensing signal it acquires to the vehicle control unit. The vehicle control unit sends control commands to the corresponding control devices based on the obstacle sensing signals. The control devices then control the corresponding door handles to perform the corresponding actions based on the control commands.

[0107] For example, see Figure 7 Taking the obstacle sensing signal as a capacitance signal as an example, the four doors are divided into left front, right front, left rear, and right rear, and the corresponding door handles are left front door handle, right front door handle, left rear door handle, and right rear door handle. The capacitance sensor at each door handle sends the detected internal capacitance signal (i.e., the obstacle sensing signal mentioned above) to the vehicle control unit. The vehicle control unit generates the corresponding door handle control command based on the received internal capacitance signal and sends it to the corresponding control device. The control device then drives the corresponding door handle to perform the corresponding action and detects the handle position of the door handle in real time to determine the execution status of the command.

[0108] The vehicle provided in this embodiment of the invention includes the door handle control device or door handle control equipment in the above embodiments. Therefore, the vehicle provided in this embodiment of the invention also has the beneficial effects described in the above embodiments, which will not be repeated here.

[0109] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0110] Finally, it should be noted that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
