cars enter the era of internet of vehicles
if you forget the parking position, press the key and your car will respond by automatically honking and flashing lights to indicate the location. unfortunately, your car is stolen. the location function of the stolen vehicle will assist the police to help you find it. drive to a strange city, intelligent system will provide you with surrounding facilities, restaurants, shopping malls, hotels all in one net, so that the strange city is no longer strange...... all of this can be done with the internet of cars.the internet of vehicles has become the main direction of intelligent transportation, with data showing that by the end of 2011, more than 500,000 new cars in china were pre-installed with in-vehicle information service terminals. it is estimated that by 2015, there will be at least 40 million mobile internet service technology users in cars. according to the consumption amount of 1000 yuan per user per year, the market space of internet of vehicles industry will be about 40 billion yuan in 2015, driving the related output value may exceed 100 billion yuan, and china is expected to develop into the largest market of vehicle-borne information service industry in the world.the internet of cars boomfollowing the internet and the internet of things, the internet of vehicles leads intelligent transportation to become another important aspect of the development of smart cities in the future.data show that china invested 137.7 billion yuan in smart city construction in 2012, with a growth rate of 15.2%, 4.8 percentage points higher than that in 2011. so far, the ministry of housing and urban-rural development has identified a total of 193 pilot cities. it is estimated that 600 to 800 cities (counties and towns) in china will build smart cities during the 12th five-year plan period. smart city itself is a network city. people have the internet, things have the internet of things, and cars have the internet of vehicles. the internet allows people to exchange information peer-to-peer, while the internet of cars allows cars to talk to each other. experts point out that cars equipped with the internet of vehicles in the future are not only efficient, environmentally friendly and intelligent, but also can provide unprecedented traffic safety guarantee and even reduce the probability of car accidents to zero.during the guangzhou asian games from november 12 to 27, 2010, more than 80 suzhou golden dragon smart buses equipped with g-bos equipment were put into service. this is the first "3g" bus in the history of the asian games, and the internet of vehicles technology officially came into the public eye.the internet of vehicles is a subdivision application of the internet of things in the automotive field, mainly utilizing technical means including vehicle-mounted electronic sensing device, mobile communication technology, automobile navigation system, intelligent terminal equipment and information network platform. the internet of vehicles combines a series of advanced internet of things technologies such as sensors, radio frequency identification, wireless communication transmission and background cloud computing, and is an important foundation for smart transportation and even smart cities. at present, the relatively mature application of the internet of vehicles in china is in the aspects of vehicle-mounted navigation and electronic no-stop expressway charging, so the identification system based on rfid, dsrc and other technologies and the electronic map, navigation and positioning of vehicle-mounted information service system have started. in other areas of technology, most are still in the trial stage due to the lack of mature business models.at present, china's intelligent transportation and internet of vehicles industry has just entered the initial stage. vehicle manufacturers have started to load on-board information terminals, and some basic on-board information services, including negative navigation, positioning and entertainment functions, have been applied. meanwhile, the application of perceptive devices in expressways and urban traffic has been promoted. after the market enters the mature stage, the internet of vehicles will be interconnected with the city's main network, and the smart city will begin to integrate and develop into a high-level smart city. this process can take 10 to 20 years.lack of core technologychina is the world's largest automobile market and mobile internet market. the combination of the two provides congenital advantages for the development of china's internet of vehicles industry. people hope to solve a series of travel problems in a simpler way, and china will usher in the rapid development of the internet of vehicles market in the future. in order to seize the opportunity, chinese enterprises have taken action. internet of vehicles alliance has been established in various places. as the core of the industrial chain, domestic vehicle manufacturers feel pressure and are increasing their efforts in technological research and development and training of professional talents. many enterprises have reached cooperation with enterprises or universities. at the same time, vehicle manufacturers are also working with mobile communication operators to prepare for vehicle networking.in april 2010, saic group strategically shook hands with china unicom, and in 2011, voice cloud driving was realized, opening the "talking era" of chinese cars. inkanet is the biggest highlight of inkanet. the in-car system not only has the necessary navigation and positioning functions, but also can make phone calls, check stocks, receive sms messages, and chat online anytime and anywhere.but new things are messy, and so is the internet of cars. in order to get on the internet fast train, many car companies are designing in-car intelligent systems according to their own understanding, and brands are reluctant to open up their systems due to safety and other concerns. many of the increasing functions are not practical. at present, the internet of vehicles system of most car companies only adds a service, and the business model of internet of vehicles has not been formed, so the development of internet of vehicles is restricted.pang chunlin, secretary general of vehicle-borne information service industry application alliance and executive director of china electronics industry standardization technology association, believes that china's internet of vehicles market has been basically mature, forming a part of consumer groups, the main problem now is that technology is not mature, lack of talent.in the era of internet of vehicles, one of the biggest changes in automobiles is automotive electronics. in addition to the traditional automotive electronic control devices of the car body, the on-board electronic control devices are also installed, which is the key to realize intelligent functions. automotive electronics and it systems will become the core competitiveness of cars in the internet of vehicles era. however, it should be noted that the domestic automotive core electronic control technology is lacking and the technical level is backward. we still have a long way to go to achieve independent innovation and form an automotive electronics industry with independent intellectual property rights.security is the goal of all partiessafety is the most basic and important requirement for people to drive cars, and the industry has never relaxed the research and development of car safety technology to improve the safety of normal driving. the auto safety technology they focus on is usually divided into active safety technology and passive safety technology according to the time point of collision, and the auto active safety market has a large space for development. according to ccid consulting, the market size of china's automotive active safety systems (including chassis control and safety systems) will exceed 100 billion yuan in 2015, with a compound annual growth rate of about 15% in the next three years.one of the important tasks of the internet of vehicles is to improve the safety of driving. the biggest change that the internet of cars brings to drivers is to make them drive more safely, and the electronic control devices of on-board cars contribute a lot. at present, many oems have corresponding products, in addition to onstar of general motors, g-book of toyota and nissan carwings, d-parter of faw group, roewe inkanet of saic motor, g-netlink of geely, and telematics. these systems basically have navigation, road condition, driving safety monitoring, vehicle condition diagnosis and other functions, they play an important role in vehicle safety, easy driving and maintenance as well as the management of public vehicles.however, in the era of internet of vehicles, technological development has not only provided further safety guarantee for people to drive, but also made people face a more complicated environment. for example, the increasing number of semiconductors in cars increases electromagnetic interference, which in turn increases safety concerns. wang huan, general manager of the semiconductor industry research center of cdi consulting, believes that the biggest safety problem facing the development of the internet of vehicles is that cars can be controlled remotely through the internet, but there is a lack of relevant laws and regulations.the healthy development of the industry depends on the formation of the industrial chain and the cooperation of relevant enterprises. at present, the industrial chain of the internet of vehicles is still not perfect, and the value chain of the internet of vehicles is still far from the standard of maturity, which is reflected in the reluctance or fear of drivers to use the internet of vehicles. what is needed now is to build an open and sustainable industrial chain based on driving safety. data collection, analysis, mining and the final auxiliary decision is the ultimate goal, it needs to be based on big data technology, then naturally involved in the information technology industry. network security manufacturers are an indispensable part of this industry chain.in the near future, the internet of cars is expected to involve finance, emergency rescue, hospitals, car maintenance, transportation, it and many other fields. of course, there is a long way to go before such a multi-tiered structure can be formed.
