Problems solved by technology

This kind of keyless entry system has greatly increased the safety of car anti-theft, but on the other hand, there is a problem: if the existing vehicles without keyless entry system want to upgrade to this kind of car keyless entry system, you need Re-replacing the car door handle and wiring laying, the later modification cost is too high; on the other hand, in the cold north, in the event of freezing rain and icing, the button on the door handle will be frozen, affecting the opening of the door

Embodiment 1

[0035] Such as figure 1 Shown is a structural block diagram of the car keyless entry system provided by the preferred embodiment of the present invention. The system includes two parts, one is the car smart key 100, and the other is the vehicle-mounted device 200, wherein:

[0036] The car smart key 100 , the car smart key 100 includes a first storage module 190 , a first processing module 110 , a first positioning module 120 , a first cellular mobile communication module 130 and a first short-range wireless communication module 140 .

[0037] The in-vehicle device 200 connected with the ignition system 300 and controlling the door lock central control system 500, the in-vehicle device 200 includes a second processing module 210, a second positioning module 220, and a second cellular mobile communication module 130 bound for communication. The cellular mobile communication module 230 and the second short-range wireless communication module 240 .

specific Embodiment approach

[0038] A mobile communication server 600 establishing a communication link with the first cellular mobile communication module 130 . The specific implementation is as follows:

[0039] Firstly, when the vehicle is turned off, the second processing module 210 acquires the ignition system 300 flameout signal, and the second processing module 210 controls the second positioning module 220 to acquire the positioning data of the parking position of the vehicle according to the flameout signal, Then send the positioning data to the mobile communication server 600 through the second cellular mobile communication module 230;

[0040] Then, the first cellular mobile communication module 130 obtains the vehicle parking position information in the mobile communication server 600, and sends the vehicle parking position information to the first processing module 110 for processing, and the first processing module 110 stores the parking location information of the vehicle in the first stor...

Embodiment 2

[0054] Such as figure 2 Shown is a structural block diagram of an automobile keyless entry system provided by another preferred embodiment of the present invention. On the basis of Embodiment 1, an acceleration sensor 150 is added in this embodiment.

[0055] (3) After the car owner carries the car smart key 100 and leaves the identification area of ​​the second short-range wireless communication module 240 of the vehicle-mounted device 200:

[0056] After the vehicle owner leaves the identification area of ​​the vehicle-mounted device 200, the first positioning module 120 locates the position of the vehicle smart key 100 all the time. The smart key 100 also includes an acceleration sensor 150, the acceleration sensor 150 is used to obtain the vibration signal of the car smart key 100, when the acceleration sensor 150 has obtained the vibration signal of the car smart key 100, the first processing module 110 controls the first positioning module 120 starts the positioning w...

Abstract

The invention discloses an automobile keyless entry system. The automobile keyless entry system comprises an automobile intelligent key, automobile-mounted equipment and a mobile communication server, wherein the automobile intelligent key comprises a first storage module, a first processing module, a first positioning module, a first cellular mobile communication module and a first short distance wireless communication module; the automobile-mounted equipment is connected with an ignition system and used for controlling a door lock center control system and comprises a second processing module, a second positioning module, a second cellular mobile communication module and a second short distance wireless communication module, and the second cellular mobile communication module is in binding communication with the first cellular mobile communication module; communication linkage is established between the mobile communication server and the first cellular mobile communication module. When the automobile keyless entry system is implemented, an automobile owner can lock and unlock automobile doors without taking out the automobile intelligent key for control or installing buttons on the automobile doors, and the automobile keyless entry system is convenient to use and install. Besides, when an existing automobile-mounted anti-theft system is replaced and updated, cost is low. Meanwhile, the automobile keyless entry system has the advantage of being high in safety.

Description

【Technical field】 [0001] The technical field of automobile electronics of the present invention mainly relates to an automobile keyless entry system. 【Background technique】 [0002] The existing car keyless entry systems mainly include the following types: [0003] 1. The on-board device and the car smart key communicate through radio frequency signals. The on-board device is always searching whether the car smart key is within the effective signal range. For example, when the on-board device detects that the car smart key is within the effective signal range, Then send an unlocking signal to the central control system, if the on-board equipment cannot detect that the car smart key is within the effective signal range within a certain period of time, then send a signal to the central control system to lock the door. The disadvantage of this technology is that the on-board equipment is always on, and at the same time it is always searching for legal keys within the range of ...
