(2) When the processor 10 determines that the first fingerprint image F1 matches the primary reference fingerprint image PI, but the second fingerprint image F2 does not match the primary reference fingerprint image PI, the processor 10 obtains pass authentication without obtaining use authentication, and each second fingerprint sensor F2 may not sense the person who has entered the vehicle C, so that the person who has entered the vehicle C places his finger on the second fingerprint sensor F2 again, and the second fingerprint sensor F2 senses again. (3) When the processor 10 determines that the first fingerprint image F1 matches the primary reference fingerprint image PI and that the second fingerprint image F2 matches the primary reference fingerprint image PI, the processor 10 obtains pass authentication and use authentication, i.e., confirms that the driver is the coming person to enter the vehicle C.

(2) When the processor 10 determines that the first fingerprint image I1 matches one of the secondary reference fingerprint images SI, but the second fingerprint image I2 does not match any of the secondary reference fingerprint images SI, the processor 10 obtains the pass authentication without obtaining the authorization to use authentication, and each second fingerprint sensor F2 may not sense the coming person who has entered the vehicle C, so that the coming person who has entered the vehicle C puts his finger on the second fingerprint sensor F2 again; alternatively, the processor 10 does not find a secondary reference fingerprint image SI matching the incoming person in the vehicle C in real time, and the processor 10 searches the database 20 for another frame of the plurality of secondary reference fingerprint images SI again. (3) When the processor 10 determines that the first fingerprint image I1 and the second fingerprint image I2 both correspond to one of the plurality of secondary reference fingerprint images SI, the processor 10 obtains the pass authentication and the authorization authentication, confirms that the coming person who wants to enter the vehicle C is the person authorized by the driver to approve the use of the vehicle C, and the processor 10 opens the doors of the vehicle C and starts the engine of the vehicle C.

Similarly, when the processor 10 determines that the first fingerprint image I1 and the second fingerprint image I2 both conform to one of the plurality of secondary reference fingerprint images SI, the processor 10 obtains the pass authentication and the authorization authentication, confirms that the coming person who wants to enter the vehicle C is the user authorized to approve the use of the vehicle C by the driver, after obtaining the pass authentication and the authorization authentication, the processor 10 sends out the start signal to operate the positioning element 30, the positioning element 30 performs positioning on the vehicle C instead of the vehicle C and establishes a map according to the surrounding environment of the vehicle C, and the positioning element 30 can also know the weather and the temperature of the position of the vehicle C, so that the user can know the environment and the traffic of the user, and the user controls the operation of the surrounding element 40 through the human-computer interface 50; alternatively, the user can send a control signal to the wireless transceiver RT through an external electronic device, and then transmit the control signal to the processor 10, and the processor 10 controls the operation of the peripheral device 40 according to the control signal. Meanwhile, the processor 10 records the settings of the peripheral device 40 and stores them as the user information UI of the database 20, and when the user senses at the first fingerprint sensor F1 and the second fingerprint sensor F2 again, the processor 10 can extract the user information UI from the database 20 according to the first fingerprint image and the second fingerprint image, and the processor 10 displays the user information UI on the human-machine interface 50.
