Keyless sensing fingerprint one-key starting system for automobile

Abstract

The invention relates to the field of automobile electronics, providing a keyless sensing fingerprint one-key starting system for an automobile. An automobile engine is started by fingerprint identification through the keyless sensing of the automobile according to the burglarproof biological specificity of human fingerprint. The system comprises a DSP (Digital Signal Processor), a memory and a press type living fingerprint sensor, wherein the DSP is respectively connected with the memory and the press type living fingerprint sensor and is used for receiving characteristic point data and other biological characteristic values of the fingerprints, which are transmitted by the press type living fingerprint sensor, acquiring the saved verification information from the memory and comparing data according to the characteristics of the fingerprints, which are verified by the verification information. According to the automobile biological characteristic burglarproof system provided by the invention, because the press type living fingerprint sensor and the DSP data processor with high performance are adopted, the fingerprint identification can be identified by using a fingerprint algorithm more quickly; by using the fingerprint encryption, the automobile burglarproof system is safer and the automobile is started more conveniently; after being identified by using automatic keyless sensing unlocking fingerprints, the automobile is started by one key; the fingerprints directly replace the automobile key to only allow the automobile to be identified by an owner; in addition, the keyless sensing fingerprint one-key starting system has high identification rate and brings a new feeling of people to directly converse with the automobile.

Description

technical field [0001] The invention relates to the field of automobile electronics, in particular to an automobile starting control system and method, and provides an automobile biometric anti-theft fingerprint recognition starting automobile engine system. Background technique [0002] Automobile anti-theft starting system is applied in a large number, but the automobile one-button starting system provided by prior art has the following disadvantages: [0003] 1. Unsafe: (1) The best mechanical keys are not safe because they can be copied. (2) Anyone can start the car by pressing the start button, which is extremely unsafe especially for children. [0004] 2. Inconvenient to use: mainly manifested in that there is no automatic window closing and automatic locking function after parking, which brings inconvenience to the owner of the car. In addition, there are potential safety hazards, which may easily cause the items in the car to be stolen. [0005] 3. Relatively poor ...

AI Technical Summary

Problems solved by technology

[0003] 1. Unsafe: (1) The best mechanical keys are not safe because they can be copied

(2) Anyone can start the car by pressing the start button, which is extremely unsafe especially for children

[0004] 2. Inconvenient to use: it is mainly manifested in that there is no automatic window closing and automatic locking function after parking, which brings inconvenience to the car owner. In addition, there are potential safety hazards, which may easily cause the items in the car to be stolen

[0005] 3. Relatively poor security: traditional optical fingerprint anti-theft devices and scratch-type fingerprint anti-theft devices are easy to be copied

Not to mention the anti-robbery function

[0006] 4. The anti-theft device without live fingerprint recognition has a low recognition rate: because the existing fingerprint sensor is optical, the rejection rate for dry, wet, dirty, peeled, knife marks and other fingers is relatively high, so it is difficult to Identify normal fingerprints

[0007] 5. High power consumption: The existing technology is to use the normally open contact of the relay to control the various parts of the car. The relay must be energized normally to work, and the relay will generate heat and power consumption for a long time, which will affect the life of the original car battery. The heat itself is more serious, and the failure rate also increases accordingly.
