     DETAILED DESCRIPTION 
       [0020]    To make the object, technical solutions, and beneficial effects of the present disclosure more apparent, the present disclosure will be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, the embodiments described herein are for explanation only and not intended for restriction of the present disclosure. 
         [0021]    As illustrated in  FIG. 1 , the unlocking method for a vehicle according to an embodiment of the present disclosure can include the following steps. 
         [0022]    S 101 , a sending end is electrically conducted to a human body. 
         [0023]    The sending end is in contact with the skin of the human body, and therefore, the sending end can be electrically conducted to the human body. 
         [0024]    Most wearable devices, such as watches and bracelets, can be in contact with the skin of the human body. For this reason, the sending end can be incorporated in a wearable device that in contact with the skin of the human body. 
         [0025]    S 102 , based on the contact between the human body and a vehicle body, a connection is established between the sending end and the vehicle body through the human body. 
         [0026]    When the human body is in contact with the vehicle body, the connection is established between the sending end carried by the human body and the vehicle body; and during the connection between the sending end and the vehicle body, the sending end carried by the human body is required to be in contact with the skin of the human body. 
         [0027]    According to user habits of opening the door of a vehicle, the contact between the human body and the vehicle body can be the contact between the hand of the human body and the door handle of the vehicle body. 
         [0028]    The medium for establishing the connection between the sending end and the vehicle body is the human body, and in this embodiment, human body coupling communication technology can be adopted. The human body coupling communication technology is to adjust the voltage of a transmitting circuit and monitor the potential difference of a receiver electrode so as to send signals; here, in addition to a potential difference in the human body, a small current will flow through the human body either. Transmission and reception of required data can be conducted with aid of bio-electricity of a biological (that is, human body) surface, and effective communication between the two parties can be achieved. Because the power of electrical signals transmitted through the human body is very low, it will not cause any harm to the human body. The human body coupling technology can use the capacitive character of the human body for signal transmission, and transfer information among equipment such as the human body and the like. 
         [0029]    A human body coupling module is provided in the sending end and the vehicle body respectively, and the process of establishing the connection between the sending end and the vehicle body can include the follows: when the human body is in contact with the vehicle body, the human body coupling module of the sending end and the human body coupling module of the vehicle body can cause the sending end to be conducted to electrical signals of the vehicle body, so as to establish a communication connection. 
         [0030]    The human body coupling module of the sending end can include a modulation circuit; the modulation circuit is connected with a first conductor, which is in contact with the skin of the human body and can transmit data by utilizing the capacitive character of the human body. The human body coupling module of the vehicle body can include a reception modulation circuit; the reception modulation circuit is connected with a second conductor, which is in contact with the skin of the human body and can detect a weak signal transmitted through the human body. 
         [0031]    In this embodiment, the transmission of a signal is as follows: the sending end sends out a signal; after passing through the modulation circuit, the signal is transmitted to the human body by the first conductor; the signal can be transmitted through the human body and transferred to the vehicle body by using the human body as a medium, and through the second conductor, the vehicle body can receive the signal transmitted from the human body. 
         [0032]    In this embodiment, the second conductor in the human body coupling module of the vehicle body is provided on an outer surface of the door handle of the vehicle body. 
         [0033]    In this embodiment, before the communication connection between the sending end and the vehicle body is established, the human body coupling module of the vehicle body will perform authorization judgment on the human body coupling module of the sending end. 
         [0034]    When the human body is in contact with the vehicle body, the human body coupling module of the vehicle body will distinguish the identity of the human body coupling module of the sending end. If the human body coupling module of the sending end has been authorized, the communication connection will be established between the sending end and the vehicle body; otherwise, if the human body coupling module of the sending end has not been authorized, the vehicle body will refuse to establish the communication connection with the sending end. 
         [0035]    S 103 , the sending end sends an unlocking instruction to unlock the vehicle body. 
         [0036]    After the connection between the sending end and the vehicle body is established, the sending end will send the unlocking instruction, and the vehicle body will be unlocked after the unlocking instruction sent from the sending end is received. 
         [0037]    In this embodiment, S 103  can include the follows. The sending end sends the unlocking instruction to a vehicle door lock system of the vehicle body; the vehicle door lock system of the vehicle body verifies the unlocking instruction; if the verification is correct, the vehicle door lock system of the vehicle body will unlock the vehicle body; if the verification is erroneous, the vehicle door lock system of the vehicle body will not unlock the vehicle body. 
         [0038]    As can be seen, the vehicle door lock system of the vehicle body can verify the unlocking instruction of the sending end and unlock the vehicle body if the verification is successful. 
         [0039]    To sum up, while the user pulls the door handle to open the door of the vehicle, the hand of the human body and the second conductor are in contact, the human body coupling module of the sending end (to be specific, through the first conductor) and the human body coupling module of the vehicle body (to be specific, through the second conductor) can cause the connection between the sending end and the vehicle body to be established by using the human body as a medium. The sending end can send the unlocking instruction to unlock the vehicle door lock system of the vehicle body, and the unlock action and the door opening action are the same action; therefore, the user can unlock and open the door of the vehicle at the same time, and the operation is more convenient.

The human body coupling module of the vehicle body can include a reception modulation circuit; the reception modulation circuit is connected with a second conductor, which is in contact with the skin of the human body and can detect a weak signal transmitted through the human body. 
         [0049]    In this embodiment, the transmission of a signal is as follows: the sending end sends out a signal; after passing through the modulation circuit, the signal is transmitted to the human body by the first conductor; the signal can be transmitted through the human body and transferred to the vehicle body by using the human body as a medium, and through the second conductor, the vehicle body can receive the signal transmitted from the human body.
