[0027] Step S5: If yes, obtain the vehicle comfort system parameter setting information corresponding to the target object in the database, and adjust the vehicle comfort system of the target vehicle based on the vehicle comfort system parameter setting information.

[0028] It should be noted that the execution subject of this embodiment may be a server or a terminal or a vehicle comfort system control device based on a smart bracelet. The following description will be made using a server as an example.

[0029] In this embodiment, when the target object needs to be in the short range of the target vehicle, the on-board comfort system of the target vehicle is adjusted. Therefore, it is necessary to first determine the short range of the target vehicle. As described in the above step S1, the target vehicle is connected to the Bluetooth in the car. Therefore, the Bluetooth can be used as a basis for judging whether the target object is in the short range. Specifically, the server determines that the area where the Bluetooth signal strength of the Bluetooth is higher than the preset Bluetooth signal strength is the hotspot radiation range, and the hotspot radiation range is the short range of the target vehicle.

[0030] The server obtains the distance between each smart bracelet near the target vehicle and the target vehicle in real time through the positioning system. As described in the above step S2, when the server detects that a smart bracelet is gradually approaching the target vehicle, the server collects the behavior characteristic information and physiological characteristic information of the target object through the smart bracelet, wherein the target object wears the smart bracelet, the behavior characteristic information includes but is not limited to the stride, the step frequency and the wrist flapping amplitude, and the physiological characteristic information includes the skin electrical response, the pulse beating intensity, the body temperature and the blood oxygen saturation.

[0031] As described in the above step S3, it is determined whether the target object is a specific user based on the behavior characteristic information and the physiological characteristic information. Specifically, step S3 includes the following steps: Performing feature extraction on the behavior feature information to obtain a behavior feature matrix corresponding to the behavior feature information, and performing feature extraction on the physiological feature information to obtain a physiological feature matrix corresponding to the physiological feature information; respectively obtaining first similarities between the behavior feature matrix and each registered behavior feature matrix in a registered behavior feature matrix library; specifically, obtaining the first similarity by calculating cosine similarities between the behavior feature matrix and each registered behavior feature matrix; wherein the registered behavior feature matrix library is obtained by collecting behavior feature information of a specific user multiple times and extracting features from the behavior feature information collected each time; If any of the first similarities is greater than a preset similarity, a second similarity between the physiological feature matrix and each registered physiological feature matrix in a registered physiological feature matrix library is obtained respectively; specifically, the second similarity is obtained by calculating the cosine similarity between the physiological feature matrix and each registered physiological feature matrix; wherein the registered physiological feature matrix library is obtained by collecting physiological feature information of a specific user multiple times and extracting features from the physiological feature information collected each time; If any of the second similarities is greater than the preset similarity, the target object is determined to be a specific user.

[0032] The behavior feature information includes data information of multiple behaviors, and the feature extraction of the behavior feature information to obtain a behavior feature matrix corresponding to the behavior feature information includes the following steps: For each of the behaviors, a standardized data vector corresponding to the behavior is constructed based on the data information corresponding to the behavior; specifically, each data in the data information is standardized in sequence using formula (1) to obtain standardized data information corresponding to the data information; each data in the standardized data information is arranged in sequence in a preset vector bracket to obtain the standardized data vector; (1) in, z is the standardized data, x is the original data, μ is the mean value corresponding to each data in the data information, σ is the standard deviation corresponding to each data in the data information.

[0035] Table 1 (3) (4) (5) (6) For example, the behavior characteristic information is shown in Table 1. According to formula (1), the standardized data information corresponding to the stride length is {0, 0.63, -0.63, 1.27, -1.27}, the standardized data information corresponding to the step frequency is {0.63, 0.63, -0.63, 1.27, -1.27}, and the standardized data information corresponding to the wrist swing amplitude is {0.67, 1.33, -0.67, 2.00, -1.33}. Then the standardized data matrix X is shown in formula (3). The covariance corresponding to the standardized data matrix is ​​calculated using formula (2): The result is shown in formula (4). Eigenvalue decomposition is performed on formula (4), and the eigenvalues ​​obtained are λ1=3.5, λ2=0.3, λ3=0.2, the eigenvector corresponding to λ1 is v1=(0.5, 0.5, 0.7), the eigenvector corresponding to λ2 is v2=(-0.6, 0.4, -0.6), and the eigenvector corresponding to λ3 is v3=(0.6, -0.6, 0.2).
