A kind of fingerprint identification automobile start and stop device and its control method

Abstract

The invention discloses a fingerprint identification car starting and flameout device and a control method thereof. The fingerprint identification car starting and flameout device comprises a fingerprint collecting sensor, a communication interface circuit, a central processor, a steering wheel unlocking unit, an electrostriction device and a circulating button switch. The fingerprint collecting sensor is connected with the central processor through the communication interface circuit. The central processor controls the steering wheel unlocking unit and the electrostriction device which controls the circulating button switch. The circulating button switch controls an engine and electrical appliances in a car. By means of the fingerprint identification car starting and flameout device and the control method thereof, keyless-starting of the car and keyless control over power-on and power-off of a car circuit are realized, and car control convenience and car safety and burglary prevention are greatly improved. Identities are recognized through fingerprints, the burglary risk of the car is greatly lowered, and the safety and burglary prevention are improved; and unlocking can be conducted only after fingerprint comparison succeeds, and thus misoperation can be prevented and reliability is improved.

Description

technical field [0001] The invention relates to the technical field of automobile electronics, in particular to a fingerprint identification automobile start-stop device and a control method thereof. Background technique [0002] , In recent years there has been a keyless start. The disadvantage of key start is that the key is easy to be lost or even stolen, so that the owner will not be able to open the door; the keyless start system can use short-range radio frequency identification (RFID) technology to automatically open and close the door lock through the chip in the smart card carried by the owner. And to start the computer system in the car, the disadvantage is that the wave frequency will be interfered by other devices and cause failure, and the second is that you still need to carry the hardware with identification function, that is, the smart card containing the chip. Once the smart card is not carried, the car cannot be started. or fail to shut off the engine. Th...

The disadvantage of key start is that the key is easy to be lost or even stolen, so that the owner will not be able to open the door; the keyless start system can use short-range radio frequency identification (RFID) technology to automatically open and close the door lock through the chip in the smart card carried by the owner. And to start the computer system in the car, the disadvantage is that the wave frequency will be interfered by other devices and cause failure, and the second is that you still need to carry the hardware with identification function, that is, the smart card containing the chip. Once the smart card is not carried, the car cannot be started. or cannot shut down the engine

The keyless start system can also use a remote one-button start, which generally uses Bluetooth transmission technology. The disadvantage is that once the remote control button is aged or the power is out, the engine cannot be started, and the remote control is easily damaged and lost.
