Description

A kind of automobile gets into start-up system

Technical field

The utility model relates to a kind of automobile and gets into start-up system, relates in particular to a kind of automobile with near field communication (NFC) function and gets into and start-up system.

Background technology

In recent years, along with socioeconomic quick growth, auto trade has also obtained swift and violent development in Chinese market, and automobile has also got into Chinese family as daily necessities widely.Simultaneously, people are also increasingly high in the requirement of traveling comfort and convenience to automobile.

How to make the automobile can be more convenient, more humane be that the user uses, and has become the direction that each company of auto trade and numerous engineer make great efforts.

Under such background, the automobile passive type gets into and start-up system has got into market, and has obtained applying widely.

Entering of automobile passive type and start-up system (Car Access Passive Entry is hereinafter to be referred as CAPE) are different from traditional vehicle and initiatively get into and Starting mode, and the car owner is not from need draw out automobile key to the whole process of start the engine into the car.The convenience and the traveling comfort of automotive use have been improved.At present at home market be used widely, and become an attraction of new model.

This system mainly comprises the passive type entering and passive type starts two parts function.Passive type gets into function and refers to that the user can directly open car door through the sliding door handle, need be by the remote-control key button.The passive type startup refers to that the car owner can as long as automobile key is positioned at car, need not rotate startup knob sparking startup with remote-control key as traditional vehicle by the direct start the engine of start button in the car.

Fig. 1 is the structural representation of CAPE system 100, and its principle of work is following:

Step 1: when CAPE system 120 receives outer triggering signal (starting stop button or grip handle touch signal), start low-frequency antenna 123, the 125kHz low frequency signal is sent, wake remote-control key 125 up;

Step 2: after remote-control key 125 is waken up, the CAPE controller is replied through 315M Hz or 434MHz high-frequency signal;

Step 3: the CAPE controller is judged current condition of the vehicle after acquiring legal high-frequency information feedback through high frequency antenna 124, carries out start the engine or opens corresponding actions such as car door.

But in the prior art, the CAPE system does not possess the function of carrying out communication with electric terminal equipment.

Thus, a kind of entering of automobile passive type and the start-up system that can carry out communication with electric terminal equipment need be provided.

Because in the communications field; Near-field communication (Near Field Communication; Hereinafter to be referred as NFC); Claiming wireless near field communication again, is a kind of short-range high frequency wireless communication technology, allows to carry out contactless Point-to-Point Data Transmission (in ten centimetres) swap data between the electronic machine.This technology develops by exempting from contact RF identification (RFID), and backward compatible RFID, mainly possibly be used for handheld devices such as mobile phone.

NFC information is transmitted through the electromagnetic induction coupled modes of wireless frequency part in the frequency spectrum, be a kind ofly provide easily, safety, the wireless connect technology of communication rapidly.NFC has taked unique signal attenuation technique, has characteristics such as distance is near, bandwidth is high, energy consumption is low.N FC and existing contactless smart card technical compatibility have become the official standard that obtains the support of more and more leading firms at present.NFC still is a kind of closely connection protocol, provides between various device easily, safety, communication rapidly and automatically.

Compare with other connection modes in the wireless world, NFC is a kind of in-plant secret communication mode, in fields such as gate inhibition, public transport, mobile-phone payment, is bringing into play enormous function.

Simultaneously, NFC also is superior to infrared and the Bluetooth transmission mode.As a kind of mechanism of exchange that satisfies the needs of consumers, NFC than infrared sooner, much more reliable and simple, need not be as infrared must strict alignment could transmit data.Compare with bluetooth, NFC is applicable to exchange financial information or responsive significant datas such as personal information towards closely transaction.

Thus, be a kind of feasible technical scheme with NFC technology introducing automobile passive type entering and start-up system.
