How do automotive applications understand and improve user driving habits?

Tencent Science and Technology Huang July 31 reported that cars are becoming a new focus of mobile technology innovation platform. A series of improvements in car life are followed. Navigation Guide Driving application, can lead the driver to the unknown place, no longer for lost and worry; music applications, let the driver feel the charm of music, enjoy a comfortable life; parking violation of the application, to help drivers understand parking information, timely handling of violations ... Travel and life are more comfortable with the presence of these automotive applications. The development of the same name automotive application automatic and its application of the same type in start-up company automatic from the angle of driving skills, combined with a large amount of data, making it possible to improve driving habits and save travel expenses. Using OBD system to change data for wealth according to the Clean Air Act, the EPA has made a hard rule for carmakers that cars manufactured after 1996 must have a OBD system (on-board diagnostics), the main purpose of which is to monitor emissions. OBD is the abbreviation of English on-board diagnostics, this system will be the engine, automatic transmission and other automotive electronic systems real-time monitoring of the operation, once the system failure, will issue the corresponding fault code, such as the automotive exhaust emissions system of the ternary catalyst failure, resulting in excessive exhaust, Once it happens, the system will alert you for 17 years, no one has used the OBD system to make any achievements. Some car enthusiasts and insurance companies used the system to test the safety of cars, but no technology company has ever used the data effectively to develop popular functions. But today, in a variety of applications, for automotive applications developers, the monitoring of the exhaust system, has become their perfect database. Intelligent driving makes travel more enjoyable according to the data provided by the OBD system, the start-up company automatic developed a product made up of automatic applications and OBD reader named "Link". When the user inserts link into the OBD jack of the car, the application will output the driver-style information for the exclusive driver, creating a comprehensive record for each drive: tracking fuel efficiency, acceleration, and engine alarms. These data records can help users better understand the car and their driving habits. At the same time, the application is able to access the engine alert code, and when the "check engine" light comes on, automatic can tell the user where the problem is. Under the guidance of the data, people and cars better running-in, unknowingly, the user will be left a large amount of maintenance costs. Automatic also added a fuel efficiency scoring function to help users develop savings in travel habits and save a fuel charge. In the course of the operation, the application will monitor whether the user will often slam the brakes, fast start and speed (these 3 actions will increase fuel consumption), and then according to the weekly rating, and when the user to do these operationsVoice prompts enable users to better understand their driving details and improve them. The same type of application developed by another start-up, the dash, also developed a ranking of driving scores, allowing drivers to understand the driving habits of the people around them to help them improve better. The two companies have developed automotive applications equipped with built-in accelerometers that provide the police with information for the first time when a car encounters an accident. Automatic's product director, Ljuba Miljkovic, said: "With mobile apps, users can feel more control, learn about travel and spending, and improve driving skills--I think it's interesting." ”
