Self-driving is one of the more discussed technologies in the automotive industry and even in the whole technology industry at this stage, and if it goes well, self-driving technology may happen in our daily life in the near future, but the happy market prospect also still has practical difficulties. v2x vehicle networking technology based on the fusion of satellite navigation system (GPS) navigation bar technology, vehicle-to-vehicle communication technology, wireless communication and remote Control magnetic induction technology has laid down the prospect of new vehicle technology development, completing the compatibility of gnss module manual type safe driving and automatic driving.
V2X Technology and Driverlessness
V2X (vehicletoeverything), i.e. vehicle-to-external information interchange. It is an important technology for intelligent living road transportation system software. It prompts communication between car and car, car and communication base station, and base station and communication base station in between. In turn, it gets a series of public transportation information such as traffic condition, road information, and passer-by information, which in turn improves driving safety, reduces congestion, improves public transportation efficiency, and gives in-vehicle game entertainment information, etc.
The first use of V2X was demonstrated by General Motors in a Cadillac in 2006. Since then, other car companies and automotive service providers have been conducting scientific research on this technology.
In simple terms, in the driverless vehicle industry, V2X is easier to complete fully automated, and vehicles equipped with this system can use the analysis of real-time traffic information to fully automatically select the best route for real-time road conditions in an autonomous driving mode, thus greatly reducing traffic congestion. In addition, according to the application of on-board controller and filming system software, it can also recognize the surrounding environment and make rapid adjustments, thus completing "zero road traffic accidents".
V2X technology will become the key to driverless technology in the future. If the Internet cloud space AI obtains information outside the scope of the traditional embedded AI vision, and the bicycle sensor is limited to the scope of vision, it only obtains information within its field of view, which is not enough for unmanned driving. In order to ensure the safety coefficient of driverless, connect the software of car network system, after the intelligent control system of bicycle achieves the limit value, Internet cloud space AI gives a layer of assurance to vehicle driverless, which can predict the address and duration of other cars' driving early and obtain information outside the scope of visual effect to achieve precise discrimination of driverless.
Driverless in 5G natural environment
V2X contains four components: V2N vehicle-Internet technology, V2V vehicle-vehicle, V2I vehicle-infrastructure construction, V2P vehicle-road people; relying on wireless communication at the four levels to complete information interchange, and then integrating some natural environment cognition, intelligent management decisions and other roles can handle the problems of autonomous driving and road safety. At this stage, the LTE-V2X specification has been clarified, and 5G-V2X will follow the development trend of 5G commercial and. Since the LTE-V2X specification was signed, the development trend of Telematics has accelerated development trend; after LTE-V2X, along with the development trend of 5G technology, V2X according to 5G will become the key to the basic construction of smart car communication industry in the future. LET-V2X takes cellular mobile network as the basic, and is formulated by 3GPP spearheaded by LG of South Korea, Qualcomm of the United States and its Huawei in our country as Specific leaders. 5G-V2X level, communications equipment vendors in collaboration with automotive companies together to promote the development trend: 2016 Huawei, Audi, BMW, Daimler, Vodafone, Ericsson, Intel, Nokia and Qualcomm created the 5G Vehicle Alliance (5GAA), applicable standardization, accelerated commercialization and promotion to brands around the world.
5G is another disruptive enhancement of communication basic after 3G. 5G solves the problem of data information transmission rate and volume for vehicle networking. 5G Internet reaches the driverless Internet technology regulations, especially low latency and high reliability, which will be the ultimate key to complete self-driving landing type. 4G link of LTE-V can only support a part of self-driving, and complete driverless must rely on extremely low latency and high reliability of 5G Internet. 5G network technology features to reach the driverless Internet technology regulations, especially in the low latency, high reliability level, whether DSRC or the current stage according to 4G LTE-V, can not be compared with it.
With the imminent arrival of the 5G period, the competitive advantage of 5G's extremely low latency will improve the timeliness of car network data collection, ensuring that cars and people, cars and cars, cars and roads are instantly connected to information, clearing driverless safety hazards, and thus pushing to complete a complete driverless.
Along with the driverless technology is improving day by day, the vehicle-type visual effect assistance system software hardware configuration has been done to the transaction level, into the cell phone software maturity, millimeter wave radar cost fee slowly reduce, accelerate the popularization of driverless and its high-precision map slowly perfect. Google has indicated that it will be ready in advance for complete driverless vehicles to be built and put into production in 2020, and traditional-style automakers such as BMW, Ford, General Motors and Volkswagen are releasing self-driving vehicles in the coming years.
