Abstract
The invention discloses a keyless unlocking and locking system for an automobile, which comprises a remote control sensor, an information control mechanism and a central controller. The remote control sensor and the central controller are connected with the information control mechanism respectively. The information control mechanism comprises four low-frequency antennas which are disposed on a left door handle, a right door handle, the centre of the top of the automobile, and a trunk of the automobile respectively. The remote control sensor uses a three-axis induction antenna and a chip with function of KEELOQ encryption. A wireless scanner is used to obtain a wireless encrypted signal, after calculating and programming of computer password experts, a computer with the greatest hardware and the most efficient program are used to decrypt the key according to the obtained signal, only 0.001% of the key is decrypted after one day, and 200 years are needed to completely decrypt the key. Therefore, the key is safe and reliable, and even if a thief copies the signal, the door cannot be opened.
Description
Technical field
The invention belongs to technical field of automotive electronics, relate to a kind of automobile door lock device, particularly relating to a kind of automobile does not have that key is opened, the lock system.
Background technology
Keyless systems is used for the above vehicle of B level car mostly at present, can accomplish that the people is being with key near car, and car opens the door automatically, and the people is being with key away from car, and car is locked a door automatically.
Cardinal principle is to lean on 2 low-frequency antennas (being installed on car door inside) transmission key detection signal (the low-frequency antenna erection plan is seen accompanying drawing 1) in the car; Key detects the back and replys an acknowledgment signal; After car is received acknowledgment signal, think key nearby, startup is opened the door automatically and is locked a door action.
Prior art has fugitiveness on key is judged, misoperation sometimes, and safe antitheft property is not strong; Software vulnerability is arranged; Can make the robber decode out and open car door, be that low-frequency antenna is installed in the car door and there is unsettled reason, because car door is a steel structure; Can shield the low frequency wireless signal, make key receive jitter.
Summary of the invention
Goal of the invention: in order to overcome the deficiency of prior art, the automobile that the invention provides a kind of high stability, no misoperation does not have that key is opened, the lock system.
Technical scheme: automobile does not have that key is opened, the lock system; Comprise remote control inductor, signal control mechanism and central controller; The remote control inductor is connected with signal control mechanism respectively with central controller; Said signal control mechanism comprises: 4 low-frequency antennas are installed on left and right sides car door grip handle, roof central authorities and automobile trunk respectively.
Principle of work: innovative point of the present invention is; In described signal control mechanism, 2 low-frequency antennas have been increased; And be arranged at car roof central authorities and automobile trunk, with original 2 low-frequency antennas that are positioned at left and right sides car door grip handle, form a more perfect signal control mechanism; To getting into the signal that the remote control inductor in the certain limit is sent around the automobile; Comprehensively control, and the signal of receiving in time is sent to central controller, so that the opening, lock of better driving automobile.
Beneficial effect: automobile of the present invention does not have that key is opened, the lock system; Through signal control mechanism in the car body and the induction of remote control inductor, signal is sent to central controller opening, locking of Control of Automobile, this scheme is reliable and stable, highly sensitive; It is high to be detected as power, can not produce misoperation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
A kind of new automobile of the present invention does not have the key door unlocking system; As shown in Figure 1; Comprise remote control inductor 1, signal control mechanism 2 and central controller 3; Remote control inductor 1, central controller 3 are connected with signal control mechanism 2 respectively, and described signal control mechanism 2 comprises 4 low-frequency antennas, and it is arranged at vehicle right and left car door grip handle, roof central authorities and automobile trunk respectively.Wherein remote control inductor 1 was realized with being connected through radio communication of signal control mechanism 2, is mainly used in the information that traffic-actuated controller structure 2 sends, and induction information is fed back to signal control mechanism 2; Signal control mechanism 2 will respond to signal output to the central controller 3 that remote controller 1 feeds back through the I/O port, by central controller 3 it made corresponding processing.
The working process that automobile of the present invention does not have the key door unlocking system is: the remote control inductor 1 that the car owner carries is in apart from the scope of 1～2 meter of car the time; Remote control inductor 1 receives the low frequency signal that signal control mechanism 2 medium and low frequency antennas send; Carry out the identification of ID coupling; And the message feedback after will discerning is to signal control mechanism 2, through emission and acceptance each other, after coupling is passed through; Then signal control mechanism 2 sends corresponding door-lock opening instruction for central controller 3, has realized that no key opens the door.
When the car owner is stopped; Remote control inductor 1 leaves apart from outside 1.5～2.0 meters scopes of car the time, and the low frequency signal induction that the low-frequency antenna in the signal control mechanism 2 sends is less than the existence of remote control inductor 1, then with signal feedback to central controller 3; By its execution action of locking a door; If non-locking door is good, then signal control mechanism 2 can drive corresponding warning device, the information of prompting car non-locking door.
Claims (2)
1. automobile does not have that key is opened, the lock system; Comprise remote control inductor (1), information Control mechanism (2) and central controller (3); Said remote control inductor (1) and central controller (3) difference link information control mechanism (2); It is characterized in that: said information Control mechanism (2) comprises 4 low-frequency antennas, is arranged at vehicle right and left car door grip handle, roof central authorities and automobile trunk respectively.
2. automobile according to claim 1 does not have that key is opened, the lock system, it is characterized in that: be provided with 3 induction antennas and the chip with KEELOQ encryption function in the described remote control inductor (1).
