Since the end of OBD: the road leading to large number of data pits?

In the OBD insurance mode, the maximum value achieved mainly through OBD vehicle monitoring lies. Its meaning is more like a car black box, with the help of the owners driving habits, mileage and other key information with the real-time control to achieve premium rate difference, if there is an accident, the insurance company can understand the dangerous condition of the equipment before the vehicle accident running, determine responsibility for the accident. For large quantities, can provide customers with fast access to model driving behavior, the insurance company may take a free way to promote vehicle OBD, combined with advertising and marketing value-added model.
     Until today, did not appear "Paul T" the first case in the true sense. Why is it so difficult hand? After all, the reason for not touched upon is difficult for you to meet the core needs of the other side!
     Car OBD auto insurance industry to bring how to give practical benefits? Insurance companies need in the end is what kind of data? Based on the difference auto insurance rates to achieve the purpose of the reform, insurance companies require at least the following three types of data:
     1, obtained by G-sensor data
     G-sensor, the English name Gravity-sensor, acceleration sensor is meant, it is a special high-tech components, can perceive changes in acceleration, acceleration is when the role of the object during acceleration forces on the object, such as shaking, falling, rising, falling and other mobile G-sensor changes can be perceived.
     By G-sensor, accelerometer can monitor vehicle owners involved in bad driving habits, such as braking, rapid acceleration and sharp turns, accidents also can manage the process. In the event of a collision, in order to prevent potentially fraudulent, insurance companies need accurate ruled an accident from which direction the vehicle is hit, whether the comic impact within milliseconds, repeated impact, whether tumbling after impact? By the acceleration and direction changes can be determined whether a collision, the impact from the front or from behind. With these data indicate that these processes are real accident occurred.
     2, Can-bus protocol cracked read information
     For the insurance company, you want to get to the impact of auto insurance payment data, you must also master the owners of bad driving habits, such as "cornering lights do not fight, do not pull the handbrake in the car, lock the car does not close the window closed, not wearing a seatbelt ...... "and so forth, OBD diagnostic trouble codes ordinary unable to provide, more is needed to break the original car's proprietary protocol.
     Bus on many types of vehicles, such as high as 500kpbs speed Canbus, or low-speed 100kbps Canbus, there are other K-line, VPW, PWM, etc., system objects connected not only with the engine ECU, ABSECU, SRSECU, instrument cluster, etc. , including centralized control locks, power windows, mirrors, lights and other car inside; there may also have intelligent communication system for satellite navigation.
     Throughout the body by the sensor, various vehicle traveling data is sent to the "bus", these data do not specify a unique receiver, all the data receiving side needs to have the required information can be read from the "bus" . In other words, you can get to by Canbus include "door windows, lights, brakes, gears, air conditioning, radar, ignition, flame, speed, fuel consumption, safety belt" and other information with the state, but because of the protection of the depot this part of the car belonging to a proprietary protocol data requires an illegal break. The workload is very large, the need for each model of each car brand even do development. But even that got the data must also bear a very big legal risk.
     3, the information acquired by the GPS
     A normal commuting daily on the city's A owners and a walking tour route daily in Yunnan B owner, the higher the risk of lower? Glance evident. In the course of the accident, the owner at what time, what place concrete collided, to be accurate to people, things, conduct accident payment management, insurance companies need to obtain location information through GPS data and mileage of the vehicle. Obviously, this part of the information is not necessarily in order to get through the OBD interface. Common GPS can calculate mileage and obtain location information, and data through the OBD interface than the "average speed * travel time" mileage calculations are more accurate, error basically controlled within 5%.
     From the bottom: the data behind the gorgeous pit father
     The above data needed for the insurance companies, the current OBD Can not achieved? Yes, of course! Universal OBD not do nothing, but careful scrutiny, you will find all sorts of data pits father behind these gorgeous:
     (1) Fault code data value just like chicken
     As already mentioned, OBD-II main function is to provide diagnostic trouble codes, when failure occurs emissions, ECU fault information and records related code, and a warning through the fault lights. Generally speaking, OBD2 trouble codes by a letter and four digits. As shown in the picture below, the majority of OBD manufacturers can only get to "PO/P2/P3400-P3FFF generic fault code information, the other for car manufacturers custom fault code information, and only to the original diagnosis., For example in terms of Volkswagen car the whole car has 15,000 fault codes, and generic fault codes less than 3000, accounting for only one-fifth of the vehicle can not meet the diagnostic requirements.
     In fact, most of the generic fault code information is of little significance for the owner, or to the public generic fault codes, for example, "P0001 representative of the amount of fuel regulator control circuit / open, P025A representative of the fuel pump module control circuit / open circuit, P0103 a representative of the air flow sensor circuit high ...... "is not it a bit being around dizzy? In general, is to detect include power systems, chassis systems, communication systems, body systems part of common faults. This information is for the safety of the vehicle does not have any influence, real-time fault will be displayed on the dashboard, such as air bags, seat belts, high water temperature and other issues will directly reminder. When these data are not driven cold passion owners used the occasion just like chicken, but also to attract what about the insurance companies?

INEMO designed detector design is based on vehicle safety

Currently, the number of car ownership in the community more and more. Meanwhile, the frequency of occurrence of the accident is also increasing. The project is based on INEMO semiconductor design a more humane automotive safety detector, the detector with its powerful features for people to be able to offer many convenient services. In the course of traveling cars, the detector can automatically detect the degree of turbulence and cars traveling road speed. When this index exceeds a critical value, the detector through voice broadcast system for the driver prompted the driver to slow down. At the same time, the detector is also capable of receiving data from the temperature sensor portion of the tire, and a processing frequency on the temperature displayed on the display, so the driver can monitor the working conditions of the vehicle tires in real time, to avoid puncture dangerous. In addition, the function of the maximum detector is its ability to simulate the vehicle driving state, the vehicle driving state is displayed visually on the computer interface, to provide a new driver to enjoy driving.
In the hot summer, if the driver is not able to keep abreast of changes in the temperature of the car tires and take appropriate protective measures, is likely to make the car dangerous puncture in the process of moving, for family and friends have a certain security threats. When the car is cornering or driving on uneven road, the driver is not able to clearly understand the performance aspects of the car. If the angular velocity or speed is too large, the risk of rollovers may make the car appear. If we can design a security detector, appeared before the car situation, through a certain test, to remind the driver, the driver in real time to facilitate understanding of the working conditions of the car, so that we can largely reduce the accident frequency.
Functional requirements skp-900
Based INEMO designed automotive safety detector, with a very powerful feature. First, it can accept data from temperature sensors car tires out, the data displayed on the screen, so that the driver can readily grasp of car tires at the temperature changes, and alert the driver to make the appropriate protection against puncture dangerous. Secondly, the security of the detector can also be readily measured vehicle speed and the degree of turbulence, and the detected data is displayed, when the degree of turbulence over the risk indicators of the detector will be a prompt, a driver's decelerating slow. Meanwhile, the detector capable of detecting the angular velocity of the car and the angular acceleration during cornering, and calculates to be subjected to centrifugal force and the centrifugal force of the car is now sold. When the car suffered centrifugal force is greater than the maximum friction is the automobile, the detector can be early warning to avoid the risk of rollover. In addition, the detector is also able to simulate the running state of the car, and the frequency on the display, so that the driver brings a whole new driving experience, while driving at any time be able to enjoy a lot of fun .
Performance standards
When the temperature reaches the set car tires tire maximum permissible temperature, the system will automatically alarm.
When the car is cornering suffered centrifugal force is greater than the maximum frictional force is set, the system will automatically alarm.
When a large extent bumpy car driving, more than the body can withstand the maximum, automatic alarm system.
Vehicle driving state can be displayed on the visual microprocessor, a driver in order to better understand the working conditions of the vehicle.
System functions can be implemented
In this system, INEMO will accept temperature from the temperature sensor is part of automobile tires, automobile tires in real time the temperature is displayed. In normal driving the car, the detector can detect the speed and acceleration of the current car, while calculating the degree of turbulence cars currently traveling. When the car at the corner intersection, the system is also able to detect angular velocity and the angular velocity of the car turning, and timely data will be displayed on the Lcd. When these data exceeds a certain indicators, the system will activate the alarm system to remind the driver, the driver in real time in order to facilitate understanding of the working conditions of the car, and make timely protective measures to avoid unnecessary losses. On the basis of these functions, the point of the maximum detector innovation is that it be able to simulate the vehicle driving state. The detector capable of velocity, angular velocity and turbulence degree car data acquisition. Then, the detector will send the data to the host computer. After the host computer receives the data, a certain integration signal to the integration of C interface built up. Then, the car model built by the interface with the current state of the auto show, in order to achieve the simulation of the car, the driver can be more intuitive understanding of the working conditions of the car, the driver provides a new driving experience vas 5054a.
During system operation, the sensors are to work. Wherein the temperature sensor and the pressure sensor in the part of the tire, the tire temperature and tire pressure monitoring in real time and transmitted via wireless transmission to the microcontroller port; the remaining sensors are disposed below the front end module as a vehicle, wherein a two-axis gyroscope, and a one-axis gyroscope with real-time monitoring of all places of the body angular speed bumps, including front and rear, left and right and up and down the six azimuth data, the other is a two-axis gyroscope to detect the angular velocity of the car when cornering, as this module data then transmitted via the USB interface to the microcontroller; transmitted to the microcontroller on a variety of data to go through the appropriate amplifier handle, and then make the appropriate A / D conversion, converted to corresponding digital signal, and then again after each value with the respective threshold comparison, if greater than the threshold value, the system will prompt the driver to the voice and displayed in each of the parameter values ​​in each of the sensors relative to the LCD and the value is immediately sent to the simulator, and the simulator to simulate the car motion. Then the driver can make preventive measures in accordance with the actual situation.

Car keys,the purchase price proportional to the car

Mr. Hao Rui Gao owners accidentally lost car keys, and later by the dealer to the factory orders with the key. However, from order to get the key, wait two weeks before Mr. Gao. A key is actually to go with for so long? This allows Mr. Gao did not understand. Also let him do not understand is that a little key, actually want to spend nearly $ 3,000. An inconspicuous car keys, is so expensive, we might take a look at its replacement cost is what the composition.
Proportional to the price and the purchase price with a spoon
"How expensive with the keys, usually with matched Keys, also 10 dollars, which turned out to be 3000 yuan car keys." Mr. Gao said. Mr. Shaw was driving the car is a Skoda Hao Rui, had landed spent nearly 300,000 yuan. Reporters interviewed the staff of the 4S shop, with key staff said the price is fixed headquarters, they have no right to change, customers are unable to do so.
Reporter consulted a number of 4S stores downtown and found the car keys generally worth a lot of money, with the key prices and the prices of basic proportional. Most of 4S shop with key offer in 1000 yuan to 5000 yuan, the price of some high-end models with the key even up to 8000 yuan. In Volkswagen Jetta, for example, with the key quotes 4S shop given 1,500 yuan; part of a joint venture brand compact car like Vios, carnival, with a key price of about 1,000 yuan; 300,000 -50 million level luxury cars, with the key prices generally above 3,000 yuan.
Your car keys in the "technology fee"
A sale manager of FAW-Volkswagen 4S shop, said Lo, each key has a password, the password matches the high cost. Some mid-alone joint venture brands spend a remote key at least 1,500 yuan or more, and some luxury brand models alone is the key necessary to 3,000 yuan or more. If the owners choose to change the whole lock, then spend a lot more expensive than a single change keys, like the BMW SUV change the whole lock a section close to $ 10,000.
Some high-end imported cars with keys and destroy the original key in the production process needs to be completed. Such imports Audi and BMW models to be imported in Germany, so costs are generated on these costs, the price will be so expensive. In addition, high-end cars to crack the code matches the level and higher, so prices naturally increase. For some models, it may be the ignition switch, doors, rear doors, the glove box door, fuel tank cap, engine cover all use the same key to open, if the replacement vehicle locks, then the site would need to be replaced more, and costs will naturally increase.
In addition, Mr. Luo told reporters, changing locks with keys and the time spent is not how long, generally two or three hours to complete. However, according to different models of different levels of security keys, write code, and match needs to spend some time. Some high-end models with the key needs to make reservations in advance to determine the chassis number of different codes and other information based on different models, so when a customer key is broken or lost, under normal circumstances can not quickly get the key. Individual luxury brand because of the need to carry back to the origin with the key business superobd, may be stretched to a two-month period.
4S shop suggestions:
Lost the key lock is best for the whole
Then, once the key is lost, is not equipped with a key like it? Still need to replace the whole lock it? Mr Lo said that for security reasons, it is recommended that consumers new key match after a good idea to replace the vehicle locks. Now new cars are standard two keys, there is a brand identification codes, inscribed with a combination of letters and numbers, the brand must not be lost. If the owner accidentally lost the car keys, it is necessary to hold the brand with the key identifier. New with the key needs and "electronic identification code" on the original vehicle anti-theft system for matching, the match is completed, the new key to enable the lost remote control keys immediately lapse.
"Even if someone picked up the old car keys, and can only be opened by mechanical key to the door, absolutely impossible to start the car." Current car remote control key has a chip inside, then insert the key, the key to the chip ID and the car alarm system After the match the correct identification code in order to start the car. After losing the keys, the safest approach is to replace a full lock. After replacing the whole lock, even if it was picked up before the lost keys, skp900 do not worry about the door will be opened.
Spoon roadside shop with no more than 1,000 yuan
Reporters in Yongfu Road Auto Parts City, you can find several shops consultation with key with the key prices, quotes several shops were given far less than the 4S shop, all in less than 1,000 yuan. In which a shop owner just as a Peugeot car owners with a new key, a new key moment is good, the owner will match the key chip laptop computer connected with the car, engine immobilizer data read for new keys and spare key performed microarray data matching, and then add the new data into the on-board computer, the entire process took less than half an hour, with a good as new keys and spare key, can successfully open and lock the doors, but also to start the vehicle, Pay only 630 yuan.
In response, Mr. Lo said, skp-900 car keys and passwords match engine anti-theft device is completed by computer, simply press the corresponding data input program, press the mouse to complete the match. Although simple, but one of the technical fees are not cheap. In addition, 4S shop is to knock off fees and material costs, while outside auto parts stores charge only the cost of materials. 4S shop for all who come with the car keys, I have to carry driving license, ID card, then check customer information, to apply with the key. The outside of the shop would not require these. It is learned that with the key is a special industry, the record must be registered in the Public Security Bureau and obtain relevant licenses, otherwise illegal operations, with chain stores and roadside mostly undocumented, security to speak of. Although the outside with the key businesses of low prices, but there is more than equipped to decode the hidden keys or malicious, but also may affect the security of the vehicle.
Therefore, from the reliability and safety starting with the key in the 4S shop expensive, can be considered to pay for peace of mind.
