According to the latest research data, it is estimated that China's annual total vehicle sales will reach 26.19 million at the end of 2016. By then, the car ownership will reach a staggering 193 million, which is the highest data of car ownership in China. With the gradual saturation of the domestic auto market and the maturity of traditional car-making technology, the entire auto industry is bound to usher in an upgrade and transformation, and today's rapidly developing car network is one of the breakthroughs in the auto industry that is highly anticipated by the Chinese people.
Vehicle networking, specifically refers to the integration of GPS positioning in the car, RFID (radio frequency technology) identification, sensors, cameras and image processing and other electronic components, in accordance with the agreed communication protocol and data interaction standards, in V2V, V2R, A large system network for wireless communication and information exchange between V2H and V2I is an integrated network capable of intelligent traffic management, intelligent dynamic information service and vehicle intelligent control.
Many people understand the Internet of Vehicles as a car network, but in essence it is an interconnected system on every car. The mechanism is similar to the relationship between mobile phones and mobile phone systems. Through the architecture information platform, the Internet of Vehicles can integrate ITS, logistics, passenger and cargo, dangerous vehicles, auto repair auto parts, car rental, enterprise vehicle management, automobile manufacturers, 4S stores, vehicle management, insurance, emergency rescue, mobile internet, etc. Ecological chain integration.
In the existing domestic car networking product promotion, almost all of them are based on the large-size touch screen of Android system. If you think about the actual functions of these products, smart phones can be realized. On the other side of the ocean, the US car network is essentially different from smartphones. It shares the information of all participants in the traffic, making the entire transportation system smarter and more efficient, and greatly reducing accidents and congestion.
Intuitively, the function that the Internet of Vehicles should achieve is: when reversing, the system will remind if there is a vehicle passing by; when passing the intersection without a signal, the system will warn whether there is a car in the blind spot; in the Internet of Vehicles and autopilot After the combination, the vehicle can obtain the speed, direction and position information of all traffic participants, as well as the information of traffic lights and signs through the Internet of Vehicles. Under the automatic planning of the system, the traffic congestion will also be greatly reduced.
Not what most people know: you can chat on the car platform, set a takeaway, look at the webpage, find a parking lot.
It is not difficult to think of the cause of this phenomenon. At present, almost all domestic car networks are dominated by Internet companies, and Internet companies have not yet got rid of the habit of rushing to seize Internet access resources. As a result, at this stage, the domestic car network is still stuck in the networking of vehicles, and has not really realized vehicle interconnection.
The lack of V2X stems from the lack of relevant standardsFrom the perspective of the entire vehicle networking industry chain, the main body is divided into four sections: end, management, cloud and big data.
The end, that is, the intelligent display mode of V2X interaction, is responsible for collecting and acquiring the intelligent information of the vehicle, and sensing the driving state and environment. The derivatives include smart phones, car navigation machines, and vehicle-mounted large screens.
Management, through the transmission of data to the cloud platform, to solve the problem of interconnection between vehicles and vehicles (V2V), vehicles and infrastructure (V2I), vehicles and clouds (V2C), mainly through network operators Derivatives include network communication sources, mobile data signals, and so on.
The cloud, that is, through the cloud platform, provides cloud services for vehicle scheduling, monitoring, management, data aggregation, and the like.
The big data platform connects the 4S shop, the automaker, the insurance company and the Internet company through integration, calculation and application data, and provides data-based user portraits, marketing strategies and other support services.
However, to achieve V2X, the tubes in this play a key role. At this stage, whether it is the pre-installed car networking products of traditional car companies or the post-installed smart car networking products of various Internet companies, they are basically in the stage of closed doors and creations, and the ecology is relatively closed. Perhaps there may be some interconnection between their own products, but there is no cross-brand interconnection.
Of course, if you want to implement V2X, you can't do it with one or two companies. First of all, we lack a mandatory and effective platform and standards. Without standards, there is no way to talk about it. Secondly, the domestic road traffic conditions have always been quite complicated, and the driver's driving habits are also different. Even the supporting transportation facilities need to be improved. The difficulty of networking these infrastructures can be imagined. Further deep, the Internet of Vehicles also relies on high-precision maps and road information to determine the lanes and precise positioning, but at present domestic high-precision has not yet achieved real commercialization.
For the status quo of domestic car networking, Feiqiang magnesium CEO Wang Qiang believes that: car networking is not the same as car + Internet, not directly connected to the phone, pad, or port the application on the phone to the big screen inside the car It is ok. In the true pre-installation sense, the Internet of Vehicles should be “car + car networkingâ€. The car networking is a local area network opposite to the public mobile Internet. It is a relatively closed technical system. Because car properties are safe and fast-moving vehicles, the most basic is safety, not the richness of functions.
Therefore, if you want to connect to the Internet, both security and intelligence are indispensable. This is the first difference in the concept. Many people think that the car network is the central control screen, but in fact, the car is a part, mobile phones, wearable devices must also be able to access related services on the cloud, according to the characteristics of the screen to display different services, provided by the cloud.
Therefore, the root cause of V2X in domestic car networking has not been the lack of relevant industry standards. However, at the 3GPP meeting in September this year, the development of the LTEV2V standard was officially completed, and it is expected that in March 2017, the rest of the standards such as V2X will be completed. China joined 3GPP as early as 1999, so it is said that the relevant standards of the Internet of Vehicles may also apply to the country, so that the real era of the Internet of Vehicles may come to an explosion next year.
