[0019] Examples:

[0020] The invention provides a vehicle networking information service system based on a vehicle-mounted intelligent gateway device, including an integrated structure suitable for the gateway and the vehicle. The vehicle is equipped with an OBD system. The OBD system is composed of CAN bus, LIN bus, and several vehicle devices. The integrated structure is connected through the OBD interface to transmit network signals with the background. The integrated structure includes an electronic control unit, a wireless transmitting device, and a storage memory unit. The above electronic unit uses the OBD interface to connect to the OBD system to obtain real-time vehicle status information. The information is processed and stored in the memory card. The device uses the SmartPush service to output to the background using the wireless transmitter at an appropriate time, and the background passes the processed vehicle The information is pushed to the user’s WeChat.

[0021] The 3D shape structure of the present invention figure 1 Shown. The gateway provides a 16-pin socket that can adapt to the OBD interface on most vehicles. The present invention is the smallest OBD detection hardware in the current market, and the weight is also lighter.

[0022] Refer to figure 1 As shown, the integrated structure of the gateway includes: an electronic control unit 7, a wireless transmitting device (GSM or CDMA) 8, and a memory unit (memory card) 9. In the information service system, there are background 10 and foreground application software WeChat 11. The electronic control unit 7 is inserted into the interface 5 through the OBD interface 6 to establish a connection with the in-vehicle OBD system, the wireless transmitting device 8 receives the data stream from the electronic control unit and transmits it to the background 10, and the storage memory unit 9 Receive the data stream from the electronic control unit and store it.

[0023] After the gateway is connected to the reserved interface 5 of the OBD system in the car through the interface 6, the electronic control unit 7 of the gateway is directly connected to the OBD electronic control unit 1, and the OBD electronic control unit 1 is connected to the CAN bus 3 and the LIN bus 4 of the car’s local area network. Connect with the vehicle device 2 to obtain the parameters returned by the sensor on the vehicle device, thereby obtaining the real-time status information of the vehicle.

[0024] A background program that can automatically receive the data stream from the wireless transmitter 8 is set on the information server, so that the user does not need to manually start the WeChat 11 to enable the communication device to receive and accumulate the data stream to the background. When the user activates WeChat 11, WeChat automatically obtains data from the background 10, and displays it after algorithm processing.

[0025] The information that the vehicle-mounted intelligent gateway can directly obtain by inserting it into the vehicle-mounted interface mainly includes vehicle fault information and some real-time driving parameters, such as vehicle speed, engine speed, and instantaneous fuel consumption. Combining the above information with time parameters, the on-board intelligent gateway electronic control unit can calculate the total number of faults, total mileage, total fuel consumption, fuel consumption per 100 kilometers, etc. of the vehicle within a period of time. It can also analyze driving behavior and save the above data in storage. The card is sent to the back-end server via GSM or CDMA for WeChat to retrieve and display to the user.

[0026] The above data can also be combined with the information set by the user in WeChat, such as the maintenance distance interval, the vehicle renewal date, etc., to remind the user of related services.

[0027] When the electronic control unit receives the information from the OBD system, it does not directly send it to the designated remote end, but first saves the received original instant information to the memory card. When the electronic control unit receives the "send" instruction, it starts the data processing program. After processing the original information, it sends the processed data to the designated remote server. The remote server pushes information to the corresponding user's WeChat through the expert system, realizing the first time, low-cost, and effective information service for the user.

[0028] Different from the prior art, the present invention has local storage and calculation functions, which improves the traditional method of sending data instantly by the traditional vehicle gateway, but first collects the original data to the memory card and does not send it. When the wireless network module detects that the vehicle is in When the flame is turned off or when other data is complete, it is suitable to send data, establish a connection with the background, and then calculate the original data in this work cycle into secondary data, and then send it to the background, and the background will push the information to the user after processing WeChat.

[0029] Moreover, when the in-vehicle smart gateway device is installed for the first time, a SmartPush service can be automatically installed, and it can be automatically started every time it is turned on. As long as the device is on, the main task of the service is to detect the connection signal and send signal of the gateway, and receive data. It determines when to transmit complete data to the background by judging the state of the vehicle. With the existence of this service, the transmission of all data is automatically completed by the system in the background. Users do not need to always turn on Bluetooth or Wifi or corresponding APP applications like traditional car networking information services. This practice of transferring data at one time also minimizes the possibility of data loss caused by continuous transmission.
