Description

Method and system for online state detection of vehicle terminal

technical field

The invention relates to the field of auto parts, and more specifically, to a method and system for detecting an online state of a vehicle-mounted terminal.

Background technique

The networking of automobiles has become a trend. When a driver is driving a car, it has become a design requirement for a new model to be able to keep in touch with the service desk or the outside world in real time through the Internet.

At present, among the vehicle network systems, relatively successful examples are General Motors' "Onstar" system and Toyota Motor's "G-BOOK" system.

GM's OnStar mainly uses wireless technology and Global Positioning System (GPS) satellites to provide comprehensive wireless services to cars. To put it simply, General Motors equipped with OnStar is equipped with collision sensing instruments on the front and rear anti-collision bars, on the doors, on the airbags inside the car, and even on the roof. Once the collision of the vehicle breaks through the sensor At the critical point, the signal transmitter of the vehicle will make a call to OnStar as soon as possible. During this process, the vehicle has been firmly positioned by satellites. For vehicles in mainland China, the phone will be directly connected to the call center in Shanghai, and the driver can immediately make necessary calls with OnStar staff. And once the most urgent situation occurs, such as the driver cannot communicate with the staff in person in an accident, the information and data processing will be fed back to the staff of the call center: the driver may have an emergency and should take action immediately. Contact police officers and medical staff to go to the location of the accident, and at this time, the satellite has firmly positioned the car so that people can find the accident location more easily.

Toyota's "G-BOOK" is mainly based on the public construction information service system of Toyota's consumer members. This system provides mutual assistance information services through on-board wireless communication terminals, and can connect various For example, mobile phones can be used to determine the location and operating status of the car. In the future, home appliances and security systems can even be controlled from the car. The feature of "G-BOOK" lies in the application of "data communication module DCM" and the secure digital card of the latest network service. Traditional communication, navigation, and in-vehicle information need to be connected by mobile phone, while DCM only needs to be easily clicked. Online, cheap service enables users to enjoy high-speed communication, regardless of login time and transmission volume. The navigation map is one of the main built-in software of "G-BOOK", which can be stored on the SD card. Insert the SD card into the socket with "E-TOWER" in ordinary supermarkets or other places, and you can download the local or the latest Maps, and then use the built-in terminal WindowsCE car software to update, the same music and computer games can also be downloaded, and the SD card is compatible with general music players, digital cameras and digital assistants (PDA), you can share images, music, Video games, files, etc.

Although the existing car networking technology has been able to provide relatively comprehensive services, there are still some shortcomings, mainly reflected in:

1) It cannot actively monitor the networking status of the car in real time, and the car owner needs to manually turn on the networking device before enjoying the networking service.

2) It is still not possible to actively provide related services based on information such as the driving status and location of the vehicle, and it is not enough in terms of active services.
