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 laying the wiring, the later modification cost is too high; on the other hand, in the cold north, in the case of freezing rain and freezing, the car buttons on the door handle will be frozen, affecting the opening of the door
[0005] At present, smart phones have become very popular, almost reaching one in everyone's hands, and mobile phones are a must-have tool that must be carried in daily life. The mobile phone number and the Bluetooth module device identification code in the mobile phone are completely different in each mobile phone, so the mobile phone can be used as It is entirely possible for a person's identification tool to be used to open the car door, but in the prior art, there is no record of using a smartphone as a car smart key

Embodiment 1

[0038] 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 a smart phone 100, and the other is a vehicle-mounted device 200. The vehicle-mounted device 200 identifies and verifies the smart phone 100. The smart phone 100 includes a mobile phone processing module 110, a mobile phone positioning module 120, a mobile phone cellular mobile The communication module 130 and the mobile phone Bluetooth module 140 ; ​​the vehicle-mounted device 200 includes a vehicle-mounted processing module 210 , a vehicle-mounted positioning module 220 , a vehicle-mounted cellular mobile communication module 230 and a vehicle-mounted Bluetooth module 240 .

specific Embodiment approach

[0039] The specific implementation is as follows:

[0040] First, when the vehicle is turned off, the vehicle-mounted processing module 210 acquires the flameout signal of the ignition system 300, and the vehicle-mounted processing module 210 controls the vehicle-mounted positioning module 220 to obtain the positioning data of the parking position of the vehicle according to the flameout signal, and then Send the positioning data to the mobile communication server 600 through the vehicle-mounted cellular mobile communication module 230;

[0041] Then, the mobile phone cellular mobile communication module 130 obtains the positioning data from the mobile communication server 600, and sends the positioning data to the mobile phone processing module 110, and the mobile phone processing module 110 sends the positioning data to Stored in the mobile phone storage module 190;

[0042] The mobile phone positioning module 120 obtains the location information of the smart phone, and sen...

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] After the car owner carries the smart phone 100 out of the identification area of ​​the vehicle-mounted Bluetooth module 240 of the vehicle-mounted device 200:

[0056]After the car owner leaves the identification area of ​​the vehicle-mounted device 200, the mobile phone positioning module 120 locates the position of the smart phone 100 all the time. Acceleration sensor 150, the acceleration sensor 150 is used to obtain the vibration signal of the smart phone 100, when the acceleration sensor 150 has obtained the vibration signal of the smart phone 100, then the mobile phone processing module 110 controls the mobile phone positioning module 120 to start the positioning work, otherwise, when the acceleration If the sen...

Abstract

The invention discloses a car keyless entry system based on a smart phone. The car keyless entry system comprises at least one smart phone, a vehicle-mounted device and a mobile communication server, wherein the smart phone comprises a mobile phone storage module, a mobile phone processing module, a mobile phone location module, a mobile phone honeycomb mobile communication module and a mobile phone bluetooth module; the vehicle-mounted device is connected with an ignition system of a car, is used for controlling a door lock central control system of the car, and comprises a vehicle-mounted processing module, a vehicle-mounted location module, a vehicle-mounted honeycomb communication module and a vehicle-mounted Bluetooth module; the mobile communication server is in communication connection with the mobile phone honeycomb mobile communication module. By implementing the car keyless entry system, a purpose that a car door can be unlocked and locked by controlling the smart phone without taking out an intelligent car key and installing a vehicle-mounted key on the car door, so that the car keyless entry system is convenient to use and install; moreover, when the existing vehicle-mounted antitheft system is replaced and upgraded, the cost is low; meanwhile, the car keyless entry system has characteristic of high safety.

Description

【Technical field】 [0001] The technical field of automobile electronics of the present invention mainly relates to a smart phone-based 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 wit...
