The OBD mode needs an external OBD box, and its interface adopts the "question and answer" method to collect data, that is, the engine ECU adopts the "interrupted" query, which causes pressure on the vehicle network and unstable communication, which not only easily burns out the engine motherboard, but also often leads to data deviation. In terms of security, it has been found that there are many ways to carry out malicious attacks on in-vehicle systems from the cloud. OBD equipment with communication module can be manipulated by hackers to remotely diagnose and unlock the vehicle, which will cause hidden dangers to the property, personal safety and privacy of the owner.
Comparatively speaking, the mobile phone car networking mode is the simplest and most convenient experience in car networking technology at present. It does not need on-board hardware equipment, but only needs the hardware equipment of the smart phone itself to automatically and intelligently extract the driving behavior information and travel information of users. Due to the computing power and storage capacity of the smart phone itself, the above data can be cached locally as needed, and synchronization can be started under network conditions, without real-time synchronization to the cloud, and almost no user's mobile phone traffic is consumed. Compared with OBD vehicle networking mode, it has obvious advantages in stability, safety and data accuracy.
At present, there are endless products in the industry that focus on car networking technology, such as car review technology. Using OBD to obtain big data of car networking, we strive to create auto insurance solutions that meet the characteristics of China. In the field of motorcycle networking, OK auto insurance can be described as the pioneer of the industry from 0 to 1: OK Drive, the first mobile car networking technology in China, won the national invention patent. Using the built-in GPS, gyroscope and other modules of the mobile phone to obtain and collect the geographical location and vehicle motion information, the user's behavior state is analyzed and judged by a specific algorithm, and some data dimensions in driving behavior are sorted and stored, including driving time, geographical location and path, acceleration during driving, etc.
