Description

A kind of automobile gets into and starts and Information Exchange 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 and gets into startup and Information Exchange 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 125, the 125kHz low frequency signal is sent, wake remote-control key 127 up;

Step 2: after remote-control key 127 is waken up, the CAPE controller is replied through 315MHz or 434MHz high-frequency signal;

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

The CAPE system does not possess the function of carrying out information exchange with electric terminal equipment at present.

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

The utility model content

In order to overcome above-mentioned defective, the purpose of the utility model is to provide a kind of automobile entering startup and the Information Exchange System that can carry out information exchange with electric terminals such as mobile phone, panel computer, notebook PCs.

To achieve these goals; The utility model provides a kind of automobile to get into startup and Information Exchange System; Comprise: the vehicle electronics module, and pass through automobile entering and the startup module that the CAN bus links to each other with said vehicle electronics module, wherein; Said automobile gets into and starts module to have: controller, the bluetooth communication module that links to each other with said controller through spi bus, and the electric terminal equipment that communicates through bluetooth approach and said bluetooth communication module.

Preferably, in the utility model, said automobile gets into and starts module also has low-frequency antenna, high frequency antenna, and automobile remote-control key.

Preferably, in the utility model, said vehicle electronics module comprises one or more in car body controller, engine management system, brake anti-blocking system, system for detecting tire pressure and the global positioning system.

Preferably, in the utility model, said electric terminal equipment can be mobile phone, notebook PC, panel computer etc.

Through above-mentioned setting, the utility model combines the bluetooth Low-power Technology with existing CAPE system, in the CAPE system, adds bluetooth low-power consumption communication interface, has expanded the function of existing CAPE system.

Bluetooth Low-power Technology standard was formally adopted by bluetooth sig (Bluetooth SIG) on July 7th, 2010, and started cooresponding certification system.Member manufacturer can submit to its product to test, through after will obtain bluetooth 4.0 standard authentications.

This technology has extremely low operation and stand-by power consumption, but uses a button cell even continuous working several years.Also have low cost simultaneously, stride vendor interoperability, 3 milliseconds low postpone, many characteristics such as extra long distance, AES-128 encryption more than 100 meters.

The bluetooth Low-power Technology has following technical advantage:

1. ultralow peak value, average and standby mode power consumption use the standard button cell can move 1 year and even the several years;

2. low-cost;

3. different vendor's equipment interactivity;

4. wireless coverage strengthens.

In addition, the automobile that the utility model provided gets into startup and Information Exchange System is supported the operation of CAPE system convention simultaneously, promptly uses automobile remote-control key, and mechanical key etc. open the door, and start vehicle etc.Therefore, even faults such as electric weight deficiency appear in the electric terminal equipment that the client carries, still can normally use vehicle through usual manner.

Description of drawings
