Explore Auto OBD function (4)——Mirage and reality of OBDII
When you Complete understanding of vehicle OBD family background and business model, whether you are sinking feeling powerful data value and profitability of the ecological chain in this case played? This is a big cake in car networking, and look at the wide variety of products emerging market, the owner not only access to vehicle status anytime through the intelligent terminal, and analyze driving behavior, driving records, even remote monitoring, real-time location etc. This is really “a box in hand, everything is nothing” While there is a will, there is a deal. Not only The box to achieve the aspirations of the owners, but also to bring a steady stream of profit point on the 4S shops and insurance companies and other third parties , everything looks perfectly combined.
When all the good dream with the reality discover, the truth began to became visible the reality is still have many of after-market companies have coveted valuable piece of cake, but got nothing. Until today, without a company to be a stronger. Why are so difficult to get together? After all, the reason is that you can not meet his needs
Maybe we need to think about the questions, how to bring practical benefits to give the insurance industry on the vehicle OBD ? what kind of data insurance companies need in the end? Based on the difference of auto insurance rates to achieve the purpose of reform, insurance companies require the following three types of data:
Acquired by the G-sensor data
G-sensor, the name is Gravity-sensor, the meaning of the acceleration sensor, it is a special high-tech components, can be perceived acceleration change when the role of the object during acceleration forces on the object, such as shaking, drop, rise, fall, and other mobile G-sensor change. , it can monitor the owners involved in the acceleration of bad driving habits by the G-sensor,such as braking, rapid acceleration and sharp turns, also can manage the accident process. In the collision, in order to prevent potentially fraudulent, insurers need accurate ruled an accident from which direction the vehicle is hit, whether or not a chain collision within milliseconds, multiple impacts, whether roll after impact? By acceleration and direction changes it can determine whether or not a hit, the impact from the front or from behind. With these data indicate that these incidents occurred in the process it is real.
Crack Can-bus protocol to read the information
For insurers, they want to get to influence auto insurance payment data, and must also master the owner’s bad driving habits, such as “cornering lights do not fight, do not pull the handbrake parking, lock your car does not close the window closed, not wearing a seatbelt …… “,the fault code diagnosis of OBD can not be provided, because it’s needed to break the original car’s proprietary protocol. Many cars on the bus type, such as a high-speed 500kpbs Canbus, or low-speed 100kbps Canbus, there are other K-line, VPW, PWM, etc., system objects connected not only with an engine ECU, ABSECU, SRSECU, a combination of instruments, such as , including centralized control locks, electric windows, mirrors, lighting and other interior compartment; another may also have intelligent communication system for satellite navigation.
Throughout the body by sensors, a variety of vehicles traveling data will be sent to the “bus”, Those data do not specify a unique recipient, who need these data to the receiving end all the information needed can be read from the “bus” . That is, it can get to include “door windows, lights, brakes, gear, air conditioning, radar, ignition, flame, speed, fuel consumption, safety belt” and other information with the state by Canbus, but because of the protection of the depot，and this part of the vehicle data belonging to private agreements, and require illegal crack. The workload is very large, it takes each model of each car brand even do the development. But even that got the data must also bear a very big legal risk.
Information obtained through GPS
Have a question, owners A work in the city and a B owners walk in Yunnan every day,Who’s the risk is relatively more large? During the accident, the owner at what time, what place specific collided, can be precise to the people, things, payments to accident management, insurance companies need to acquire location information through GPS data and mileage of the vehicle. Obviously, this is not necessarily part of the information available through the OBD interface only. Common GPS can calculate mileage and obtain location information, but also data than through OBD interface “with an average speed * time” mileage calculations are more precise, fundamental errors can be controlled within 5%.
But Is this data useful？
