When the user places the finger in the corresponding position of the ultrasonic fingerprint acquisition device, the ultrasonic fingerprint acquisition device can acquire the fingerprint information of the user, and then sends the corresponding fingerprint information to the fingerprint processing device 200 for processing, so as to realize subsequent vehicle starting control operation. Because the fingerprint of each person is unique, the starting control of the vehicle is realized in a fingerprint identification mode, a key or other starting equipment does not need to be carried, the loss of the key or other starting equipment is avoided, and the risk that the vehicle is stolen is increased.

It should be noted that the number of the preset fingerprint information is not unique, and the fingerprints of the respective fingers of each user are different due to the uniqueness of the fingerprints, so that in order to facilitate the implementation of the starting control operation of the vehicle, the user can input the fingerprint information of different fingers as the preset fingerprint information according to the habit of the user or other factors. It should be understood that, in other embodiments, it may be that the users using the same vehicle are not unique, and multiple users may respectively enter their respective fingerprint information as the preset fingerprint information, so that each user may perform the start control operation of the vehicle.

Further, when the user inputs fingerprint information through the door handle fingerprint collector 120, the door handle fingerprint collector 120 can also directly send the fingerprint information to the fingerprint processing device 200 for comparison and analysis with the preset fingerprint information. When the fingerprint information is consistent with the preset fingerprint information, the fingerprint processing device 200 performs communication authentication with the PEPS through the vehicle bus, and after the communication authentication is successful, the PEPS sends a corresponding control signal to the door lock module of the vehicle to control the opening of the vehicle door, so that a user can conveniently enter the vehicle.
