The invention provides a
fingerprint-based speed limiting device of an
automatic transmission automobile, and a control method thereof, belonging to the technical field of automobiles. The problem that the highest driving speed is not limited through
fingerprint identification corresponding to different identities can be solved by the invention. The device comprises a
fingerprint sensor for acquiring biological fingerprints and an EMS (electronic
monitoring system), wherein an electronic air
throttle and a fingerprint identification controller are respectively connected on the EMS, the fingerprint identification controller is connected with the fingerprint sensor, a
host interface is further connected on the fingerprint identification controller, the fingerprint identification controller is used for receiving fingerprint data detected by the fingerprint sensor, performing storage, comparison and deletion on the fingerprint data in a
fingerprint database according to input signals of the
host interface and outputting a set control speed limiting
signal to the EMS, and the EMS is used for controlling the opening degree of the electronic air
throttle. The control method comprises the following steps of: A. performing fingerprint identification and registration; B. judging the control conditions for starting speed limitation; and C. judging fingerprint information. The device and the method are based on a fingerprint
identification technology and can limit the highest driving speed for different users.
