S204: and the vehicle-mounted intelligent terminal determines a front target road section according to the acquired real-time vehicle position, and takes the associated driving event as a driving event which can possibly trigger the vehicle-mounted intelligent terminal to record. In the embodiment of the invention, a positioning module of the vehicle-mounted intelligent terminal acquires the real-time vehicle position and determines the target road section in front of the vehicle according to the position information of the target road section in the planned path. Because the electronic map in the vehicle-mounted intelligent terminal cannot be updated in real time, namely the electronic map cannot be the latest electronic map, the condition that the vehicle-mounted intelligent terminal cannot be triggered to record the driving event according to the target road section determined by the electronic map exists.
S3: determining the size of a data packet to be transmitted of event data corresponding to the driving event according to a preset event parameter list;

Because a certain time is consumed for starting and connecting the Bluetooth network, when the vehicle reaches a preset distance in front of a target road section, the Bluetooth network connection of the vehicle-mounted intelligent terminal is started and the event data are transmitted to the mobile phone terminal, so that the event data can be effectively transmitted to the mobile phone terminal in time when being generated and further uploaded to the Internet of things cloud platform, and the event data can be monitored more timely.
Because the target road section determined according to the electronic map may be different from the road section type in the actual road, that is, when the electronic map is not updated in time, the embodiment of the present invention further includes: when the vehicle-mounted intelligent terminal does not generate event data in the target road section, acquiring running record video information of the vehicle-mounted intelligent terminal in the running time of the target road section; and sending the driving record video information to a mobile phone terminal through a Bluetooth network, and forwarding the driving record video information to an Internet of things cloud platform through a second mobile network by the mobile phone terminal. And the Internet of things cloud platform updates the road information of the pre-stored electronic map at the position of the target road section according to the driving record video information, and publishes sharing, wherein objects shared by publishing of the pre-stored electronic map updated by the Internet of things cloud platform are all accessed vehicle-mounted intelligent terminals and mobile phone terminals.
When the vehicle-mounted intelligent terminal generates event data corresponding to the driving event at the non-target road section; storing the event data in a vehicle-mounted intelligent terminal; judging whether the data volume of the event data is larger than a preset flow threshold value of the current first mobile network; if the number of the event data is larger than the preset value, starting the Bluetooth network connection of the vehicle-mounted intelligent terminal, sending the event data to the corresponding mobile phone terminal, and forwarding the event data to the Internet of things cloud platform by the mobile phone terminal; if the number of the event data is smaller than the preset value, uploading the event data to the internet of things cloud platform through the first mobile network, and uploading the event data through the first mobile network adopts a communication protocol between the internet of things cloud platform and the vehicle-mounted intelligent terminal configured in the embodiment. According to the technical scheme, the event data generated at the non-target road section are locally stored firstly, and when the data volume is larger than the preset flow threshold value, the Bluetooth network is started to transmit the event data, so that the problem that unpredictable event data transmission is generated at the non-target road section when the target road section cannot be inconsistent with the actual road condition in the electronic map is solved; meanwhile, event data generated by the non-target road section are sent to the Internet of things cloud platform to update, release and share the electronic map to the vehicle-mounted intelligent terminal, and the accuracy of setting the target road section by the vehicle-mounted intelligent terminal according to the electronic map is facilitated.
In order to further improve the driving safety of the vehicle, the embodiment of the invention also comprises the following steps: the Internet of things cloud platform analyzes the event data to obtain corresponding coping strategy information of the corresponding driving event; sending the coping strategy information to a vehicle-mounted intelligent terminal and/or a mobile phone terminal for event coping prompt; the prompting mode comprises display screen display and/or voice prompt, the prompting content comprises the type of the driving event and a coping strategy, and if the prompting content is that the road section in front is a tunnel driving event, a driver asks to turn on a vehicle lamp, and the vehicle slows down.
