Detailed Description

Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and that the present application is not limited by the example embodiments described herein.

Summary of the application

As mentioned above, the advent of vehicles greatly facilitates human travel, and in order to ensure safety of vehicles, door locks are generally provided in vehicles. The door of the existing vehicle is often provided with a mechanical lock, and therefore, a user must wear a key to open the door. When the key is lost or forgotten to be carried, the key is difficult to open the door, and the key is easy to be picked up by people, so that the automobile is stolen, and the like.

Therefore, an optimized door lock solution for vehicles is desired. Of course, the door lock solution of the present invention is also applicable to other places such as doors, and the present invention is only for convenience of illustration by taking the door lock of the vehicle as an example, and does not limit the application of the present invention.

Specifically, the intelligent lock can be arranged in a plurality of places of the vehicle, so that the intelligent lock is arranged at the place of the vehicle to improve the use convenience of the user and meet the use habit of the user, which is a technical problem to be considered firstly, and further, after the intelligent lock is arranged at the place, a corresponding structural design scheme and an intelligent control scheme are designed. Besides, the smart lock also needs to consider the problem of security.

In view of the above technical problems, the inventor of the present application has selected to integrally set the smart lock on the handle of the vehicle door after research, for the following reasons: when a user opens the door, the user must hold the handle, that is, holding the handle is the action that each user will produce when opening the door. Therefore, the selection of integrating intelligence into the handlebar can greatly improve the convenience of use for the user. As described above, in many cases, the handle is applied to the door opening, and therefore, the handle of the present invention is not limited to the vehicle door, and may be applied to other cases.

More specifically, in the technical scheme of the application, the unlocking device for the vehicle comprises a handle which is suitable for being installed on a vehicle door and comprises a detection area formed on the outer surface of the handle; and the identification module is embedded in the handle and corresponds to the detection area, so that when the hand of a user holds the handle to open the vehicle door, the identification module is suitable for collecting fingerprint information of the hand for living body identification and unlocking identification.

Preferably, in the technical solution of the present application, the detection area is preferably disposed at a middle area of an outer surface of the handle (e.g., a middle area of an inner side surface, a middle area of a bottom surface, etc.), so that when a user holds the handle, a middle finger of the user corresponds to the detection area to enable fingerprint recognition of the middle finger of the user. It should be noted that, during the process of opening the door, the user usually and habitually attaches the index finger, the middle finger, the ring finger and the small finger to the inner side surface of the handle, and then pulls the door open, and during the process, the index finger, the middle finger and the ring finger apply force to make the three fingers cling to the handle, so that the unlocking recognition can be realized by recognizing at least one of the three fingers. In the present invention, the detection area is provided in a middle area of the outer surface of the handle (particularly, in a middle area of the inner side surface), and the unlocking recognition of the middle finger of the user is preferably performed. For example, in the process of opening the vehicle door, a user generally and conventionally attaches the index finger, the middle finger, the ring finger and the little finger to the inner side surface of the handle in the process of opening the vehicle door, and then pulls the vehicle door, and in the process, the index finger, the middle finger and the ring finger apply force to enable the three fingers to be attached to the handle, so that unlocking recognition can be realized by recognizing at least one of the three fingers.

It should be understood that, because the identification module is embedded in the handle and the detection area is formed on the outer surface of the handle, the unlocking is realized by the user in the door opening process, so that the whole unlocking process and the door opening process are more convenient.

It is worth mentioning that the existing handles have two types: concealed and conventional. In the case of a motor vehicle, for example, when the door handle is embodied as a concealed door, the detection region is preferably arranged in the middle region of the inner side of the handle, because: since the hidden door handle is accommodated in the door when not in use, the detection area is arranged on the inner side surface of the handle, so that the detection area can be prevented from being exposed and polluted, and the detection result can be prevented from being influenced.

Further, in order to improve safety, in the technical solution of the present application, it is preferable that an identification module having a living body identification function is adopted as the identification module.

Based on this, the present application provides an unlocking device for a vehicle, which includes: a handle adapted to be mounted to a vehicle door, the handle including a detection region formed on an outer surface thereof; and the identification module is embedded in the handle, wherein the identification module corresponds to the detection area, so that when a hand of a user holds the handle to open the vehicle door, the identification module is suitable for collecting fingerprint information of the hand for living body identification and unlocking identification.

Based on this, the present application also provides a vehicle door unlocking method, which includes the steps of: acquiring fingerprint information of fingers of a user when the user holds the handle through an identification module embedded in the handle; and determining whether to open the vehicle door based on the comparison between the fingerprint information and preset authorized fingerprint information.

Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.

Exemplary vehicle and unlocking device for vehicle

As shown in fig. 1 to 6, the unlocking apparatus for a vehicle according to the embodiment of the present application is illustrated, in which the unlocking apparatus for a vehicle 200 integrally provides a smart lock to a handle of a door of a vehicle 100, so that a user can perform smart unlock recognition and living body recognition when opening the door through the handle, in such a manner that the safety and convenience of unlocking the vehicle are improved.

Specifically, as shown in fig. 2 and 3, the unlocking device 200 for a vehicle includes a handle 210 adapted to be mounted to a vehicle door, the handle 210 including a detection region 211 formed on an outer surface thereof, and an identification module 220 embedded in the handle 210, wherein the identification module 220 corresponds to the detection region 211, so that when a user's hand holds the handle 210 in order to open the vehicle door, the identification module 220 is adapted to collect fingerprint information of the hand for living body identification and unlocking identification. Of course, the unlocking apparatus 200 for a vehicle further includes a lock unit 230 communicably connected to the identification module 220 to unlock the lock unit 230 to open the door of the vehicle 100 after the living body identification and the unlocking identification pass.

As described above, in the present disclosure, the detection region 211 is preferably disposed in a middle region of an outer surface of the handle 210 (e.g., a middle region of the inner side surface 212, a middle region of the bottom surface 213, etc.), so that when a user holds the handle 210, a middle finger of the user corresponds to the detection region 211 to perform fingerprint recognition on the middle finger of the user. It should be noted that, during the process of opening the vehicle door, the user generally and conventionally applies the index finger, middle finger, ring finger and small finger to the inner side surface 212 of the handle 210, and then pulls the vehicle door, and during this process, the index finger, middle finger and ring finger apply force to make the three fingers cling to the handle 210, so that the unlocking recognition can be realized by recognizing at least one of the three fingers. In the present embodiment, the detection region 211 is disposed in a middle region of the outer surface of the handle 210 (particularly, in a middle region of the inner surface 212), and preferably performs unlocking recognition on the middle finger of the user.

It should be understood that, since the identification module 220 is embedded in the handle 210 and the detection region 211 is formed on the outer surface of the handle 210, it is convenient for a user to unlock the door during the door opening process, so that the whole unlocking process and the door opening process are more convenient.

It is worth mentioning that there are two types of existing door handles 210: concealed and conventional. When the door handle 210 is embodied as a concealed door handle, the detection region 211 is preferably arranged in the middle region of the inner side 212 of the handle 210, because: since the hidden door handle 210 is housed in the door when not in use, the detection region 211 is disposed on the inner side surface 212 of the handle 210 to prevent the detection region 211 from being exposed and contaminated, which may affect the detection result.

In order to improve the security, in an example of the present application, the identification module 220 is a 3D module, that is, the identification module 220 is implemented as a module capable of collecting depth information of a photographed target, for example, a coded structured light camera module, a speckle structured light camera module, a TOF camera module, and the like. Specifically, the 3D module includes projection subassembly and receiving element, projection subassembly transmission detects the light, shines user's finger again, is received after the reflection by receiving element, and then receiving element obtains the three-dimensional information of user's finger according to the light signal that receives, and then can carry out unblock discernment. It should be noted that, although the three-dimensional information may not necessarily obtain the living body information, the recognition advantages brought by the three-dimensional information may be equivalent to the living body recognition in the present invention, for example, the living body recognition function is realized or realized similarly by the three-dimensional information such as the pore size, the position, the shape of sweat pores, the correlation of capillary vessels, etc.

Fig. 5 illustrates a block diagram of the identification module 220 according to an embodiment of the present application. As shown in fig. 5, the identification module 220 includes a projecting component 221 and a receiving component 222, wherein the projecting component 221 is adapted to project detection light, and the receiving component 222 is adapted to receive the reflected detection light, so as to obtain three-dimensional information of the finger of the user through the projected detection light and the received detection light. More specifically, the projection module 221 includes a circuit board 2211, a light source 2212 electrically connected to the circuit board 2211, and an optical system 2213 located on a projection path of the light source 2212; the receiving module 222 includes a receiving circuit board 2221, a photosensitive chip 2222 electrically connected to the receiving circuit board 2221, and an optical lens 2223 located on a photosensitive path of the photosensitive chip 2222.

At present, the projection assembly of the 3D module generally uses an infrared light source, so that the interference of the environment on the 3D module is avoided. However, since the present invention is measured after the finger is attached to the outer surface of the grip 210, there is no interference of ambient light or the like in this process. Therefore, the light projected by the projection assembly can be visible light, namely the projection assembly emits visible light, and the visible light is received by the receiving module after being reflected by the finger. Further, since the light source of the projection assembly of the present invention is a light source capable of projecting visible light, the light is visible in dark and low light environments, that is, the visible light emitted by the projection assembly will be emitted through the detection area 211 and seen by the user, and the user is guided to place the finger on the area for identification. That is, in the embodiment of the present application, the projection component can be used as a part of the 3D module, and can also be used as the guiding unit 240 for guiding the user to accurately place the finger on the detection area 211 in a low-light or dark-light environment to be recognized as unlocked.

It should be understood that, in some examples of the present application, the directing unit 240 may also be separately provided, as shown in fig. 4, for example, when the light source of the projecting assembly is a light source adapted to project infrared light, an additional light source adapted to project visible light is required to be used as the directing unit 240. That is, in some examples of the present application, the unlocking device 200 further includes a guiding unit 240 embedded in the handle 210, and the guiding unit 240 is adapted to project visible light to identify the position of the detection area 211.

It should be understood that compared with the conventional image recognition fingerprint, the 3D module can generally only acquire the fingerprint outline, the horizontal distance, and the like, and the depth information acquired through the 3D module can provide information in the vertical and horizontal directions, other than the outline, the distance, and the like, so that the information is richer and more difficult to crack.

Further, in the present embodiment, the detection area 211 of the handle 210 is made of a light-permeable material, for example, it may be implemented as a transparent medium material, such as glass or the like. The projection assembly and the receiving assembly are arranged at a certain included angle, the included angle ranges from 3 degrees to 180 degrees, the problem of the distance between the projection assembly and the receiving assembly and the detection area 211 of the handle 210 is considered, in order to better realize detection, the distance between the detection area 211 and the receiving assembly cannot be too small, so that the included angle can be properly enlarged to realize detection, and the preferable included angle ranges from 60 degrees to 150 degrees.

That is, in the present embodiment, the angle between the axis of the projecting assembly and the axis of the receiving assembly ranges from 3 ° to 180 °. Preferably, the angle between the axis of the projecting assembly and the axis of the receiving assembly ranges from 60 ° to 150 °.

Further, when the 3D module is implemented as a TOF camera module, the projection assembly includes a circuit board, a light source mounted and electrically connected to the circuit board, and an optical system located on an optical path of the light source for modulating the detection light projected by the light source. In this specific example, the light source is preferably a visible light source, and the optical system is an optical diffraction element, ground glass, or the like. It is worth mentioning that, since the detection area 211 is not too large, in some embodiments of this particular example, the projection assembly may not be configured with the optical system. The receiving assembly of the TOF camera module comprises an optical lens, a photosensitive chip and a receiving circuit board, wherein the receiving chip is electrically connected with the receiving circuit board, and the optical lens is positioned on a photosensitive path of the receiving chip.

Correspondingly, when the 3D module is implemented as a coded structured light camera module, the projection assembly comprises a circuit board, a light source, a Mask (Mask) and an optical system, the light source is electrically connected to the circuit board, the light source emits visible light to obtain a specific pattern through the Mask, and the visible light is emitted to the fingers of a user through the optical system; or may not include an optical system. The receiving assembly comprises a lens, a receiving chip and a receiving circuit board, the receiving chip is electrically connected with the receiving circuit board, and the optical lens is positioned on a photosensitive path of the receiving chip. The light source may be implemented as an LED lamp.

Correspondingly, when the 3D module is implemented as a speckle structure light camera module, a projection component of the speckle structure light camera module comprises a circuit board, a light source and an optical system, wherein the light source is electrically connected to the circuit board, and the optical system is positioned on an optical path of the light source; the optical system may be a collimating system and an optical diffractive element and the light source is typically a VCSEL laser projector.

In another specific example of the present application, as shown in fig. 6, the identification module 220 is implemented as a spectroscopy apparatus comprising: the optical system comprises a spectrum chip and an optical system 223A located on a photosensitive path of the spectrum chip, wherein the spectrum chip comprises a light detector array 221A and a filter structure 222A located on the photosensitive path of the light detector array 221A, and the filter structure 222A comprises at least one modulation unit corresponding to at least one light detector in the light detector array 221A.

Specifically, in the spectrum device according to the embodiment of the present application, the optical system 223A is optional, and includes, but is not limited to, a lens assembly, a dodging assembly, and the like. Preferably, the filtering structure 222A is a broadband filtering structure 222A in a frequency domain or a wavelength domain, wherein the modulation units of the filtering structures 222A are not identical in the pass spectra of different wavelengths. The modulation unit of the filter structure 222A may be a structure or a material having a filtering characteristic, such as a super surface, a photonic crystal, a nano-pillar, a multi-layer film, a dye, a quantum dot, an MEMS (micro electro mechanical system), an FP etalon (FP etalon), a cavity layer, a waveguide layer, a diffraction element, and the like. For example, in the embodiment of the present application, the filtering structure 222A may be a light modulation layer in chinese patent CN 201921223201.2. In other examples of the present application, the filtering structure 222A may also be a narrow-band film, a grating, a light scattering element, or the like to realize narrow-band spectral recognition.

In the embodiment of the present application, the light detector array 221A may be a CMOS Image Sensor (CIS), a CCD, an array light detector, or the like. In addition, in some examples of the present application, the spectroscopic apparatus further includes a data processing unit 224A, wherein the data processing unit 224A includes, but is not limited to, a processing unit such as an MCU, a CPU, a GPU, an FPGA, an NPU, an ASIC, and the like, which can export data generated by the image sensor to the outside for processing.

For example, taking the wide-spectrum filtering structure 222A as an example, after the light intensity information is measured by the image sensor, the light intensity information is transmitted to the data processing unit 224A for recovery calculation. The process is described in detail as follows:

let the intensity signals of the incident light at different wavelengths λ be denoted as x (λ), the transmission spectrum curve of the filter structure 222A be denoted as T (λ), the filter structure 222A have m groups of modulation units, and the transmission spectrum of each group of modulation units is different from each other, and overall, the filter structure 222A can be denoted as Ti (λ) (i ═ 1,2,3, …, m). Each set of modulating cells has a corresponding physical pixel (i.e. the photodetector) below it, detecting the intensity bi modulated by the filtering structure 222A.

In a specific embodiment of the present application, one physical pixel is taken as a group corresponding to one group of modulation units as an example, but the present invention is not limited thereto, and in other embodiments, a plurality of physical pixels may be taken as a group corresponding to one group of modulation units. Therefore, in the spectrum calculating device according to the embodiment of the present application, at least two groups of modulation units constitute one "spectrum pixel" (it can be understood that multiple groups of modulation units and corresponding photodetectors constitute a spectrum pixel). It should be noted that the number of effective transmission spectrums (transmission spectrums for spectrum recovery, called effective transmission spectrums) Ti (λ) of the filter structure 222A may not be consistent with the number of modulation units, and the transmission spectrums of the filter structure 222A are artificially set, tested, or calculated according to a certain rule according to the identification or recovery requirement (for example, the transmission spectrum of each modulation unit tested by the above modulation unit is an effective transmission spectrum), so the number of effective transmission spectrums of the filter structure 222A may be less than the number of modulation units, and may even be more than the number of modulation units; in this variant, a certain transmission spectrum curve is not necessarily determined by a set of modulation units. Further, in the technical solution of the present application, at least one spectral pixel may be used to restore the spectral image of the measured object.

Preferably, in this embodiment of the application, the spectrum chip has a modulation region and a non-modulation region, wherein the filter structure 222A is disposed in the modulation region and is adapted to modulate incident light, and then received by the image sensor to obtain spectrum information, while the non-modulation region may not have any structure, and a filter such as R, G, B may also be disposed to obtain light intensity information, that is, when a finger is placed in the detection region 211 of the handle 210, the modulation region of the spectrum chip of the spectrum device may obtain spectrum information to determine whether the finger is a living body, and the non-modulation region obtains light intensity information to form an image to determine whether the fingerprint is consistent with a fingerprint pre-stored in the fingerprint library, so as to achieve unlocking.

That is, in the present embodiment, the spectrum chip has a modulation region and a non-modulation region, and the filtering structure 222A is located in the modulation region. Of course, in other examples of the present application, the non-modulation region may also be regarded as a part of the filtering structure 222A, especially when the non-modulation region is an R filtering unit, a G filtering unit, and a B filtering unit, that is, the filtering structure 222A further includes at least one non-modulation unit corresponding to at least one photodetector in the photodetector array 221A, wherein the at least one non-modulation unit is selected from any one of the R filtering unit, the G filtering unit, and the B filtering unit.

It should be noted that in this embodiment, the spectral signal obtained by the spectral device does not necessarily need to be restored with a spectral curve for living body judgment, but can be directly judged according to the response, specifically, in an embodiment, reference spectral response data of the spectral-based analysis device to a reference object is obtained first; then, acquiring identification spectrum response data of the object to be identified by the spectrum-based analysis equipment; and determining the identification result of the object to be identified based on the comparison result of the reference spectral response data and the identification spectral response data, wherein the specific details can be found in the CN202110275126X of china.

It should be noted that, in the embodiment of the present application, the unlocking device 200 for a vehicle further includes a guiding unit 240 embedded in the handle 210, wherein the guiding unit 240 is disposed inside the handle 210 and projects visible light onto the detection area 211 to identify the position of the detection area 211. The directing unit 240 is further configured to illuminate the finger of the object to be identified, such that the light is reflected and received by the spectroscopic assembly.

It should be noted that before the fingerprint information is collected by the identification module 220 embedded in the handle 210, a sensor 250 may be further disposed to determine whether the identification module 220 needs to be turned on. Specifically, if the identification module 220 is always in the working standby state, a large power consumption may be required, so that the identification module 220 may be controlled to switch between the sleep state and the working state, and only activated to enter the working state when in use. Accordingly, a sensor 250 may be configured to determine whether the identification module 220 is to be used. In one embodiment, the sensor 250 may be implemented as a distance measuring sensor 250 for identifying whether a user approaches, and if the user approaches through the distance measuring sensor 250, the identifying module 220 is switched to the working state.

Of course, in other examples of the present application, the sensor 250 may also be other types of sensors 250, for example, the sensor 250 is a TOF module, wherein the TOF module is in periodic operation to reduce power consumption. Specifically, when the user approaches, the TOF module receives the information and transmits the information to the processor, the processor controls the identification module 220 to enter a working state, and the guiding unit 240 starts working to guide the user to detect the position of the area; the sensor 250 may be disposed on the B-pillar of the automobile. Of course, the sensor 250 may also be disposed on the handle 210, for example, the pressure sensor 250, and when the user places the hand on the handle 210, the sensor 250 transmits a signal to the processor to further control the identification module 220 to enter the working state, which is not limited in this application.

In summary, the unlocking device 200 for a vehicle according to the embodiment of the present application is explained, which integrally provides a smart lock to the door handle 210, so that a user can perform smart unlock recognition and living body recognition when opening the door through the handle 210, and thus, the safety and convenience of unlocking the vehicle are improved.
