The function of native system
(1) fingerprint opens the door
When the car owner need open car door; Press as long as will point on the fingerprint capturer on the Door Lock; System gets access to car owner's fingerprint image automatically and matees with fingerprint in the depositing fingerprint database, if fingerprint comparison is correct, is identified as validated user; System's freeing vehicle anti-theft state sends the instruction of opening the door; If the fingerprint comparison mal, then further operation of system's refusal, the oil supply circuit that cuts off vehicle simultaneously carries out white lock, the concurrent visual alarm of speaking.
(2) fingerprint igniting.
When the car owner need start vehicle; Press as long as will point on the vehicle launch fingerprint acquisition instrument; System gets access to car owner's fingerprint image automatically, and matees with fingerprint in the fingerprint database, if fingerprint comparison correctly then is a validated user; System's freeing vehicle anti-theft state is connected IC Ignition Control circuit start vehicle; If the comparison fingerprint is not a validated user, then the oil supply circuit of system's cut-out vehicle carries out self-locking, and sends the acousto-optic alarm control signal.
(3) sound and light alarm antitheft
System is when carrying out the fingerprint identification to the user, if coupling is made mistakes, system thinks that the disabled user is operating vehicle, and then vehicle control of fuel supply circuit breaks off in system, sends the sound and light alarm signal simultaneously, improves system's theftproof performance.
(4) password emergency starting
When abnormal condition (being scratched etc. like finger) appear in user's finger, when fingerprint capturer can't collect finger print information, perhaps because of power shortage fingerprint identification module can't normal operation the time, available password came the emergency starting vehicle.Be to guarantee security of system, password only buy car in installments main I (handler) use, simultaneously the car owner only in the fingerprint identification through revising emergency cryptosystem under the situation.For preventing that others from malice souning out password, when importing the password mistakes continuous three times, system forbids inputing password, can input password after one hour, thereby reduces the possibility that password is decrypted.
The utility model adopts fingerprint recognition Control of Automobile and the break-make of car firing unit and the switch of arrangements for automotive doors; Solved the problem of traditional mechanical lock in order to be prized; And in real life; Adopt the driver of traditional mechanical lock also to exist and leave behind key, perhaps with the problem of key lock in car, and the fingerprint recognition mode has solved this problem.
