For ordinary technicians in this field, this specification can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0020] It should be understood that the "system", "device", "unit" and / or "module" used herein are a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

[0021] As shown in this specification and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "comprise" and "include" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0022] Figure 1 It is a schematic diagram of the module structure of the vehicle lock control system 100 shown in some embodiments of this specification.

[0023] like Figure 1 As shown, the vehicle lock control system 100 (hereinafter referred to as system 100 ) includes a first acquisition module 111 , an identification module 112 , an activation module 113 , a signal sending module 114 , and a control module 115 .

[0024] In some embodiments, the first acquisition module is configured to acquire a biometric feature of the target object. In some embodiments, the biometric feature includes at least one of a face image, a fingerprint, and an iris feature.

[0025] For example, the first acquisition module may be a camera built into the vehicle body, a fingerprint sensor, an iris camera, or other devices.

[0026] In some embodiments, the recognition module is configured to perform user recognition based on the biometric features. For example, the recognition module can compare the collected face image, fingerprint, iris features, etc. with the face image, fingerprint, iris features, etc. of the pre-stored target user (such as the owner of the car or its legal user) to achieve user recognition.

[0027] In some embodiments, the recognition module can also determine the degree of credibility of the target object as the target user based on a confidence assessment model, and in response to the degree of credibility being lower than a first preset threshold and higher than a second preset threshold, issue a prompt message to prompt the target object to collect more biometric features, such as voice information.

[0028] In some embodiments, the activation module is configured to activate the battery controller in response to the target object being a target user.

[0029] In some embodiments, the signal issuing module is configured to issue a target signal based on the activated battery controller, wherein the target signal includes at least one of a battery voltage signal, a start-stop signal, and a key electrical signal.

[0030] In some embodiments, the control module is configured to activate a vehicle body controller based on the target signal to control a switch of a target component.

[0031] In some embodiments, the target components include vehicle doors, windows and lamps.

[0032] In some embodiments, the control module is further configured to: determine a current state of the target component; in response to the current state of the target component being open, control the target component to be closed; in response to the current state of the target component being closed, control the target component to be open.

[0033] It should be noted that the above description of the vehicle lock control system and its platform is only for convenience of description and does not limit this specification to the scope of the embodiments. It is understandable that for those skilled in the art, after understanding the principle of the system, it is possible to arbitrarily combine the various platforms or form a subsystem to connect with other platforms without deviating from this principle. In some embodiments, Figure 1 The first acquisition module 111, identification module 112, activation module 113, signal sending module 114, and control module 115 disclosed in the specification can be different platforms in a system, or one platform can realize the functions of two or more platforms mentioned above. For example, each platform can share a storage database, or each platform can have its own storage database. Such variations are all within the protection scope of this specification.

[0034] Figure 2is an exemplary flow chart of a vehicle lock control method according to some embodiments of this specification. Figure 2 As shown, the process 200 includes the following steps 210 to 250. In some embodiments, the process 200 may be executed by the system 100.

[0035] Step 210: Obtain the biometric features of the target object. In some embodiments, the biometric features include at least one of a face image, a fingerprint, and an iris feature.

[0036] For example, the first acquisition module may be a camera built into the vehicle body, a fingerprint sensor, an iris camera, or other devices.

[0037] Step 220: Perform user identification based on the biometric feature.

[0038] For example, the recognition module can compare the collected facial images, fingerprints, iris features, etc. with the pre-stored facial images, fingerprints, iris features, etc. of the target user (such as the car owner or its legal user) to achieve user recognition.

[0039] In some embodiments, the recognition module can also determine the degree of credibility of the target object as the target user based on a confidence assessment model, and in response to the degree of credibility being lower than a first preset threshold and higher than a second preset threshold, issue a prompt message to prompt the target object to collect more biometric features, such as voice information.

[0040] For more information about the confidence assessment model, see Figure 3 The corresponding content.

[0041] For example, the recognition module can determine the degree of credibility that the target object is the target user based on the confidence assessment model. If the obtained credibility is lower than the first preset threshold but higher than the second preset threshold, it means that based on the currently obtained information, it is not possible to determine or directly deny that the target object is the target user. Therefore, further information needs to be obtained for identification. For example, voiceprint features can be identified based on voice information, etc., so as to further improve the accuracy of recognition.

[0042] If the credibility is not lower than the first preset threshold, it can be confirmed that the target object is the target user. If the credibility is not higher than the second preset threshold, it is determined that the target object is not the target user, and the state of the current target component will not be modified.

[0043] Step 230: In response to the target object being a target user, activate the battery controller.

[0044] For example, activating the battery controller from sleep mode to standby mode.

[0045] Step 240 : Sending a target signal based on the activated battery controller.

[0046] The target signal includes at least one of a battery voltage signal, a start / stop signal and a key electrical signal.

[0047] Step 250 , stimulating a vehicle body controller based on the target signal, thereby controlling the switch of a target component.

[0048] In some embodiments, the target components include vehicle doors, windows and lamps.

[0049] In some embodiments, the control module is further configured to: determine a current state of the target component; in response to the current state of the target component being open, control the target component to be closed; in response to the current state of the target component being closed, control the target component to be open.

[0050] This method can simplify the operation logic of locking / unlocking the user's vehicle, improve the user's anti-theft security, eliminate traditional signal interference, and increase reliability. In addition, the present invention conforms to the intelligent development trend of future smart cars, frees up some of the driver's attention, and improves the user's driving interactivity and convenience.

[0051] It should be noted that the above description of the process 200 is only for example and illustration, and does not limit the scope of application of this specification. For those skilled in the art, various modifications and changes can be made to the process 200 under the guidance of this specification. However, these modifications and changes are still within the scope of this specification.

[0052] Figure 3 is an exemplary schematic diagram of a confidence assessment model according to some embodiments of the present specification.

[0053] In some embodiments, system 100 may determine confidence 350 that the target object is the target user based on biometrics 310 , historical biometrics 320 , and historical usage data 330 of the target object and confidence assessment model 340 .

[0054] The confidence assessment model is a model for the confidence that the target object is the target user. In some embodiments, the confidence assessment model can be a machine learning model. For example, a recurrent neural network (RNN) model, or other trained machine learning models.

[0055] In some embodiments, the input of the confidence assessment model includes the target object's biometrics 310, historical biometrics 320, and historical usage data 330, and the output includes the confidence 350 that the target object is the target user. The historical biometrics 320 may be the biometrics that the target user has input in the past, and the historical usage data 330 may be the data of the target user information corresponding to the historical use of the vehicle.

[0056] In some embodiments, the confidence assessment model can be obtained by various methods, for example, based on multiple labeled training samples, trained by gradient descent method or other feasible methods.

[0057] In some embodiments, the training samples and their corresponding labels can be determined based on historical data. The training samples can be obtained based on the historical usage data of the sample vehicle. The training samples may include the historical usage data of the sample vehicle in the first historical period when it was used historically, the historical biometrics in the first historical period, and the biometrics of the target object collected at the second historical time point. The label is whether the target object collected at the second historical time point is the target user of the sample vehicle. If so, the label value is 1, otherwise it is 0.

[0058] Both the first historical period and the second historical point in time are historical events, and the first historical period is earlier than the second historical point in time.

[0059] As an example, the training samples can be input into the initial confidence assessment model to obtain the output of the initial confidence assessment model; the loss function can be constructed based on the output of the initial confidence assessment model and the labels corresponding to the training samples; the parameters of the initial confidence assessment model can be iteratively updated based on the loss function; until the iteration end condition is met, the training is completed, and a trained confidence assessment model is obtained. The iteration end condition includes the convergence of the loss function and the number of iterations reaching a threshold.

[0060] In some embodiments of this specification, a more accurate estimate of vehicle unlocking risk can be made through a machine learning model, which is conducive to timely risk control.
