Wherein, the wearable device can be a smart watch, a smart phone and the like.

[0051] Specifically, when the wearable device detects the vehicle, the wearable device prompts the user to detect the vehicle, and automatically selects the last connection mode to connect the vehicle communication, such as last time through Bluetooth, then this time through Bluetooth to connect the vehicle, and the default connection vehicle mode can be set on the wearable device, such as through the Internet and the vehicle system.

[0052] Step S11, receiving the biological characteristics of the user through the biological information detection device preset on the vehicle;

[0053] The biological information detection device includes a fingerprint panel, a voice device, an iris device, and a face recognition device.

[0079] If yes, the biological characteristics are further authenticated to determine whether the user matches the authorized user;

[0080] If no, the control device sends a message to the wearable device whether authorization is needed.

[0081] The step of determining whether the user matches the authorized user includes:

[0082] Comparing and matching the biological characteristics with the authorized biological characteristic information to obtain a matching value;

[0083] Determining whether the matching value reaches a first preset threshold;

[0084] If yes, it is determined that the user matches the authorized user successfully, and the authentication is successful;

[0091] The first preset threshold and the second preset threshold are used for screening the user whose biological feature has a difference, so as to further determine whether the authorized biological feature information of the authorized user needs to be updated, thereby improving the accuracy of biological feature recognition, improving the efficiency and safety of vehicle authentication, avoiding that the user whose biological feature has a difference fails in subsequent matching, the vehicle authentication accuracy is low and the efficiency is low, and the user experience is affected.

[0092] The step of acquiring historical information of the authorized user in the interval last time and determining whether the authorized biological feature information of the authorized user needs to be updated according to the historical information specifically includes:

[0098] The historical information of the authorized user in the interval last time is acquired, and the difference degree is calculated according to the biological feature of the user. If the difference degree is small, it indicates that the biological feature of the user has changed, and the authorized biological feature information needs to be updated, so as to improve the accuracy, efficiency and safety of biological feature recognition.

[0099] According to the length of the time interval, it is determined whether the authorized biological feature information of the authorized user needs to be updated, the accuracy of updating the authorized biological feature information of the authorized user is improved, and the phenomenon of multiple recognitions of the user in a short time is avoided.
