       [0035]    The specific aspects of the present disclosure, which have been illustrated by the accompanying drawings described above, will be described in detail below. These accompanying drawings and description are not intended to limit the scope of the present disclosure in any manner, but to explain the concept of the present disclosure to those skilled in the art via referencing specific aspects. 
       DETAILED DESCRIPTION 
       [0036]    Reference will now be made in detail to exemplary aspects, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which same numbers in different drawings represent same or similar elements unless otherwise described. The implementations set forth in the following description of example aspects do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with aspects related to the present disclosure as recited in the appended claims. 
         [0037]    The aspects of the present disclosure provide an anti-theft method for a balance vehicle. The method may be applied into a balance vehicle and other terminal devices for controlling the balance vehicle, wherein, the terminal devices may be mobile phones, computers, digital broadcasting terminals, message transceivers, game consoles, tablet devices, medical devices, fitness devices, personal digital assistants and the like. 
         [0038]      FIG. 1  is a flow diagram illustrating an anti-theft method for a balance vehicle according to an exemplary aspect. As shown in  FIG. 1 , the method may include steps S 101  to S 103 . 
         [0039]    In step S 101 , first physiological characteristics information (e.g., a first set of physiological characteristics) of a current user (e.g., a first user) on the balance vehicle may be obtained. 
         [0040]    In one aspect, the first physiological characteristics information may include at least one of weight and area occupied by a foot. 
         [0041]    In step S 102 , predetermined second physiological characteristics information (e.g., a second set of physiological characteristics) may be obtained from storage (e.g., memory). 
         [0042]    The predetermined second physiological characteristics information may be predetermined physiological characteristics information of an owner of a balance vehicle or physiological characteristics information of a user associated with the owner, such as physiological characteristics information of a friend or family of the owner. Such that, the owner may prestore the physiological characteristics information of the user enabled to use the balance vehicle so as to ensure that the user may use the balance vehicle normally. 
         [0043]    In step S 103 , prompt information may be outputted to prompt that the current user is different from a predetermined user in response to a determination that the second physiological characteristics information excludes the first physiological characteristics information. 
         [0044]    In the aspect, the above technical solution may obtain first physiological characteristics information of a current user on the balance vehicle (such as weight and area occupied by a foot of the current user), obtain stored predetermined second physiological characteristics information (such as physiological characteristics information of the owner of the balance vehicle), and output prompt information to prompt the user that the current user is different form a predetermined user when the second physiological characteristics information excludes the first physiological characteristics information (namely the physiological characteristics information of the current user is not the predetermined physiological characteristics information), such that the balance vehicle may be prevented from being stolen and the property loss of the user may be avoided. 
         [0045]    Wherein, the second physiological characteristics information may be one or more, and may belongs to one user or multiple users. When determining whether the second physiological characteristics information includes the first physiological characteristics information or not, it is expected to determine whether the first physiological characteristics information is the same as or similar to the second physiological characteristics information. Whether it is similar means whether the value of the first physiological characteristics is in an acceptable error range of the value of the second physiological characteristics, when it is in the error range, it may be determined that the second physiological characteristics information includes the first physiological characteristics information. 
         [0046]      FIG. 2  is a flow diagram illustrating another anti-theft method for a balance vehicle according to an exemplary aspect. As shown in  FIG. 2 , when the first physiological characteristics information includes weight, the above step S 101  may include step S 201 .

As shown in  FIG. 3 , when the first physiological characteristics information includes the area occupied by a foot, the above step S 101  may include step S 301 . 
         [0051]    In step S 301 , the area occupied by a foot of the current user on the balance vehicle may be obtained via a pressure sensor installed on the balance vehicle. 
         [0052]    In the aspect, the area occupied by a foot of the current user on the balance vehicle may be obtained via a gravity sensor installed on the bottom of the underpan of the balance vehicle. The size of a foot of the human body may not change and may be recognizable, therefore, whether the current user is the predetermined user may be determined via the area occupied by a foot of the human body, such that the accuracy of the determination may be guaranteed, the balance vehicle may be prevented from being stolen, and the property loss of the user may be avoided. 
         [0053]    Of course, in order to improve the accuracy of the determination, whether the current user is the predetermined user may be determined via the weight and the area occupied by a foot, such that prompt information may be outputted when it is determined that the current user is different from the predetermined user. 
         [0054]    In one aspect, the outputting prompt information may include controlling the balance vehicle to output the prompt information, wherein, the prompt information may be outputted by at least one of displaying content and playing voice. 
         [0055]    In the aspect, the prompt information may be outputted directly via the balance vehicle, such as the balance vehicle may generate an audio alarm, so that the attention of the people around the balance vehicle may be caught, which may stop the thief from stealing the balance vehicle and avoid property loss of the user. 
         [0056]    In another aspect, the outputting prompt information may also include controlling a terminal associated with the balance vehicle to output the prompt information, wherein, the prompt information is outputted by at least one of displaying content and playing voice. 
         [0057]    In the aspect, the terminal associated with the balance vehicle may be controlled to output the prompt information, such as the owner&#39;s terminal being bound to the balance vehicle may be controlled to output the prompt information so as to prompt the owner that the balance vehicle is stolen. For example, the prompt information may be outputted by displaying content such as a short message, and may be outputted by playing voice, the user may be informed easily. 
         [0058]    Of course, in order to achieve better results, the balance vehicle and the terminal associated with the balance vehicle may be controlled to output the prompt information concurrently.

         [0061]    In step S 402 , the second physiological characteristics information may be updated according to the update instruction. 
         [0062]    In the aspect, when the user wants to perform adding, deleting and modifying operations to the predetermined second physiological characteristics information, the update instruction with respect to the second physiological characteristics information may be inputted, such as an adding instruction, a deleting instruction and a modifying instruction, so that the second physiological characteristics information may be updated. 
         [0063]    For example, the owner of the balance vehicle may create an account and set a login password. The predetermined second physiological characteristics information may be stored in the account. The owner may input the correct login password to login the account, and then may update the second physiological characteristics information. In this way, other people may not update the second physiological characteristics information, the security of the balance vehicle may be guaranteed.

         [0066]    In step S 502 , the second physiological characteristics information may be updated according to the inputted physiological characteristics information. 
         [0067]    In the aspect, when the update instruction is received, the physiological characteristics information inputted by the user may be obtained. The predetermined second physiological characteristics information may be updated according to the physiological characteristics information. Such that the realtime and accuracy of the second physiological characteristics information may be guaranteed, and the accuracy of the determination that whether the balance vehicle is stolen may be guaranteed. 
         [0068]    Wherein, when obtaining inputted physiological characteristics information, the physiological characteristics information may be obtained via any one of the followings.

         [0070]    In the aspect, the user may directly input the physiological characteristics information on the terminal, such as 53 kg of the weight, 370 cm 2  of the area occupied by feet. In this way, the user may input the physiological characteristics information on the terminal, which is very convenience. 
         [0071]    Method two, the physiological characteristics information of a user on the balance vehicle may be obtained. 
         [0072]    In the aspect, the physiological characteristics information of the user may be obtained via the gravity sensor and the pressure sensor installed on the balance vehicle, such as the weight and the area occupied by a foot of the human body.
