[0043] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0044] Some technical terms of the present application are explained as follows:

[0045] ECU: Electronic Control Unit, electronic control unit, also known as "driving computer", "vehicle computer" and the like. In terms of use, it is a microcomputer controller specially used for automobiles, also called automobile special purpose single-chip microcomputer. It is composed of microprocessor (CPU), memory (ROM, RAM), input / output interface (I / O), analog / digital converter (A / D) and large-scale integrated circuits such as shaping and driving, just like ordinary single-chip microcomputer.

[0046] Please refer to Figure 1 , Figure 1 The flow chart of the control method of the hidden door handle in an embodiment of the present application. In the embodiment, the control method of the hidden door handle comprises:

[0047] S110: obtaining the starting identification information of the door handle;

[0048] The starting recognition information can be one of multiple types (e.g., sound, image, etc.) or a combination of multiple types. When it is an image, it can be an image including a user's own biological feature, or other types of images. When it is an image including a user's own biological feature, it can be that the user directly places a part of the user's own biological feature (e.g., a palm) at the door handle, and the door handle identifies the palmprint by recognizing the palm, or the user places a photo including a palm at the door handle, and the door handle identifies the palmprint in the photo. When the starting recognition information is other types of images, the user places the image (e.g., a picture including a black cat police officer) at the door handle, and the door handle identifies the black cat police officer in the picture.

[0049] S120: Compare the starting recognition information with preset verification recognition information, and obtain a comparison result.

[0050] The verification information can be pre-existing in the door handle or sent to the door handle in real time, and can be always unchanged or changed according to a preset rule, all of which belong to the scope of the present application. The comparison result can be consistent, inconsistent, or partially consistent. When the palmprint information recognition fails, the user is reminded that the palmprint information is invalid in the form of voice or sound and light.

[0051] S130: Control the hidden door handle according to the comparison result and a preset rule.

[0052] When the comparison result is consistent, it is determined to be qualified; or when the comparison result is inconsistent, it is determined to be qualified; or when the comparison result is partially consistent, it is determined to be qualified. When the comparison result is partially consistent, a proportion of the consistent part can be set to determine whether it is qualified or not.

[0053] In some embodiments of the present application, the starting recognition information and the verification information are both the palmprint information of the user.

[0054] When the obtained palmprint information of the user is consistent with the preset palmprint information of the user, the comparison result is qualified; when the obtained palmprint information of the user is inconsistent with the preset palmprint information of the user, the comparison result is unqualified. When the comparison result is qualified, the hidden door handle is controlled according to a preset rule.

[0055] When the hidden door handle is in the retracted state, and when the first detection point detects the obtained palmprint information of the user, the hidden door handle is controlled to be unfolded.

[0056] When the hidden door handle is in the unfolded state, and when the first detection point and the second detection point simultaneously detect the obtained palmprint information of the user, the hidden door handle is controlled not to be retracted.

[0057] When the hidden door handle is in the unfolded state, and when the second detection point detects the acquired user's palm print information, the hidden door handle is controlled to retract.

[0058] The positions of the first and second detection points can be set according to actual needs. In this embodiment, the first detection point is the outside of the door handle and the second detection point is the inside of the door handle, but it is not limited to this.

[0059] like Figure 2 As shown, Figure 2 This is a flowchart of a method for controlling a hidden door handle according to an embodiment of this application. In this embodiment, process S301: Collect palmprint information. After filtering, if the palmprint information is valid, proceed to process S302; if the palmprint information is invalid, no operation is performed. Process S302: Obtain pre-learned palmprint information from the memory via the vehicle ECU. Process S303: Determine if the collected palmprint information exists in the pre-stored palmprint information. If the collected palmprint information does not exist in the stored palmprint information, continue with action S301. If the collected palmprint information is stored in the palmprint information, proceed to process S304. Process S304: If the collected palmprint information exists in the stored palmprint information, proceed to process S305. Process S305: Determine if the vehicle currently meets the conditions for the hidden door handle to pop open and retract. If the conditions are met, proceed to process S306. If the conditions are not met, remind the user that the palmprint information is invalid via a voice module or an audible and visual alarm module. Process S306: Control the hidden door handle to pop open and retract via a DC motor.

[0060] This application pre-records palmprint information and detects it using a camera or scanner. When a palmprint is detected, it is compared with the user-recorded information. If the comparison is successful, the hidden door handle is either unfolded or retracted. The application uses palmprint recognition to determine whether the door handle needs to be unfolded or retracted. Cameras or scanners are installed on the inside and outside of the door handle to detect the presence of a hand. When the hidden door handle is unfolded, if an object is detected on both the inside and outside of the handle simultaneously, the anti-pinch function is triggered, and the hidden door handle does not retract. If the hidden door handle is unfolded, and the inside of the handle is not triggered, but the outside of the handle is triggered, the retraction function is executed. If the hidden door handle is retracted, and the outside of the handle is triggered, the door handle unfolds. The palmprint detection method is not limited to cameras or scanners; any method capable of recognizing palmprint information falls within the scope of protection claimed in this application.

[0061] In some embodiments of this application, the method for controlling a concealed door handle further includes:

[0062] Obtain the verification and identification information. Obtaining the verification and identification information includes:

[0063] Collect palmprint signals;

[0064] Amplify the palmprint signal;

[0065] Filter the palmprint signal;

[0066] When the first detection point and the second detection point simultaneously detect the user's palm print information for a period of time longer than a preset time, the current user's palm print information is collected.

[0067] The palmprint information of the current user is stored, and the palmprint information of the current user is used as the verification and identification information.

[0068] Before use, user palmprint information needs to be learned and stored in the memory via the car ECU. The palmprint information extraction method of this invention is shown in the figure above. Palmprint signals are collected by a camera or scanner, and the signals are amplified and filtered by a circuit. Palmprint information is simultaneously collected from the inside and outside of the hidden door handle and maintained for more than 10 seconds. The palmprint information collected from the inside and outside door handles is stored in the memory. The palmprint information is then stored in the memory via the car ECU (102) for matching palmprint information. When using the device, the palm position may be different each time, requiring the learning of more than 5 sets of palmprint information.

[0069] like Figure 3 As shown, Figure 3 This is a system schematic diagram of a control device for concealing a door handle according to one embodiment of this application. In this embodiment, the control device for concealing a door handle includes:

[0070] A palmprint recognition sensor, configured to detect the user's palmprint information;

[0071] A filter processor is configured to filter the output signal of the palmprint recognition sensor;

[0072] The data storage module is configured to store the user's palmprint information;

[0073] Concealed door handles;

[0074] A DC motor is configured to drive the hidden door handle to perform an unfolding and retracting action;

[0075] The electronic control unit is configured to control the palmprint recognition sensor to detect the user's palmprint information; control the data storage module to store the user's palmprint information; and control the DC motor to unfold and retract the hidden door handle.

[0076] For example, the system structure of this application mainly includes the following parts: palmprint recognition sensor (101), filtering processing (102), data storage module (103), vehicle ECU (104), power supply module (105), DC motor (106), and hidden door handle (107). The palmprint recognition sensor (101) can be a camera or scanner to detect the user's palmprint; the filtering processing (102) is used to filter the palmprint recognition sensor (101) to improve the accuracy of palmprint detection; the data storage module (103) is used to store the user's palmprint information; the vehicle ECU (104) module is used to detect palmprint information, store the user's palmprint information, and drive the DC motor to control the hidden door handle to unfold and retract; the power supply module (105) is used to power the entire system; and the DC motor (106) is used to drive the hidden door handle (107) to perform the unfolding and retracting action. In this invention, the user pre-enters palmprint information, and the palmprint information is detected by a camera or scanner. When the palmprint information is detected, it is compared with the information entered by the user. After the comparison is successful, the hidden door handle unfolds or retracts. The door handle is retracted or extended using palmprint recognition. Cameras or scanners installed on the inside and outside of the handle detect human hands. When the hidden handle is extended, if both the inside and outside sensors detect an object, the anti-pinch function is triggered, and the hidden handle does not retract. When the hidden handle is extended, if the inside sensor does not trigger, but the outside sensor does, the handle retracts. When the hidden handle is retracted, if the outside sensor triggers, the handle extends. The data storage module can be located locally on the door handle or on a cloud server. Information is not limited to storage in memory; any method that allows information to be stored, such as cloud storage, is acceptable.

[0077] This invention allows users to pre-register their palmprint information. The palmprint is then detected using a camera or scanner. When a palmprint is detected, it is compared with the user-registered information. If the comparison is successful, the hidden door handle either unfolds or retracts. Specifically, palmprint recognition determines whether the door handle needs to be unfolded or retracted. Cameras or scanners are installed on the inside and outside of the door handle to detect human hands. When the hidden door handle is unfolded, if an object is detected on both the inside and outside of the handle simultaneously, the anti-pinch function is triggered, and the hidden door handle does not retract. When the hidden door handle is unfolded, if the inside of the handle is not triggered, but the outside is triggered, the retraction function is executed. When the hidden door handle is retracted, if the outside is triggered, the door handle unfolds.
