What is the car network
The definition of the Internet of Vehicles is different according to the industry background. The traditional car network is defined as the electronic tag installed on the vehicle to extract the vehicle information through radio frequency and other technologies, so as to effectively supervise and provide an integrated service system. However, with the rapid development of Internet technology and various industries, the traditional definition of car networking is not enough to cover the entire content of today's car networking. According to the definition of the strategic alliance of technology innovation in the car networking industry: the car network is the car network, the car network Based on the network and the vehicle-mounted mobile Internet, in accordance with the agreed communication protocol and data interaction standards, a large system network for wireless communication and information exchange between the vehicle and the person, the vehicle and the road, the vehicle and the Internet, and then the system The “filter cleaning†of massive data, the platform processes the data, and realizes the integrated network of intelligent traffic management, intelligent dynamic information service and vehicle intelligent control. It is a typical application of Internet of Things technology in the field of transportation system.
What is a car networking system?
Vehicle networking system refers to the use of advanced intelligent technology, sensing technology, network technology, computing technology, and control technology to make the system fully aware of roads and traffic, so that all vehicles can collect information through their own environment and state, and All kinds of information of its own are uploaded to the Internet big data platform, and the central processor collects, analyzes and processes a large amount of uploaded information. The system will control each vehicle involved in the traffic, and control each road in real time for use. Provide traffic efficiency and safety.
The current phase of the car network
The car machine is the abbreviation of the car infotainment product installed in the car. The car machine can realize the interaction between the driver and the vehicle and the car in some functions, and increase the driver's user experience and safety factor. Some cars include functions such as scheduled maintenance, remote diagnosis, telephone call, voice control, and vehicle rescue.
Smartphone, domestically represented by Baidu Carnet, foreign products represented by Apple carplay and android auto. The driver can project the contents of the mobile phone onto the screen of the car, making the vehicle intelligent system more flexible and malleable, giving the driver a more convenient feeling of getting started.
Map navigation, many vehicles have navigation, but due to slow version updates and other issues, the actual usage is very small, the average driver has turned to use the mobile APP to operate.
Voice technology, the key technologies in the computer field are automatic speech recognition technology (ASR) and speech synthesis technology (TTS). It is the development direction of human-computer interaction in the future, and voice becomes the most promising human-computer interaction in the future. Voice has more advantages than other ways of interacting, and voice technology will become an important part of the Internet of Vehicles.
WCDMA/LTE mobile communication technology, in-vehicle Wi-Fi and 3G/4G and other secure, high-speed mobile communication technologies provide the possibility for the fast-moving vehicle to access the Internet, and also bring huge benefits to mobile operators. In-vehicle Wi-Fi is a special Internet access device for modern vehicles. In-vehicle Wi-Fi transforms mobile vehicles into a mobile network, and operators obtain location information of mobile terminal users through LBS (LocaTIon Based Service). With the support of the GIS platform, users are provided with corresponding services, so that drivers or passengers can enjoy the ubiquitous information service. Therefore, in-vehicle Wi-Fi technology and WCDMA/LTE mobile communication technology will become a key part of smart cars.
HUD (Head Up Display), many luxury cars now come with simple HUD accessories, but only simple real-time speed and simple navigation mapping. However, many domestic and foreign technology companies have begun to design and develop new HUDs. Even front windshields are large HUDs that can be operated by the driver's limb control, human-computer interaction or in-vehicle sensors. The driver got rid of the phone and solved the distraction.
OBD (On-Board Diagnos TIc on-board diagnostic system), OBD initially can monitor the car's emissions by monitoring the car's power and emissions control system. When the vehicle's power or emission control system fails, the fault light will illuminate when the amount of pollution exceeds the set standard. Nowadays, OBD is integrated into detection, maintenance and management. The system will enter the ECU (Electronic Control Unit electronic control unit, also known as "driving computer") of the engine, gearbox and other systems to read the fault code and other related data. Now part of OBD has integrated GPS chip, acceleration sensor, etc., can obtain driving data, combined with mobile phone App can play a certain security role (vibration, displacement, ignition alarm), real-time monitoring of vehicle conditions.
CAN (Controller Area Network) is one of the most widely used fieldbuses in the world. In recent years, its high reliability and good error detection capability have been valued and widely used in automotive computer control systems.
RFID (Radio Frequency IdenTIficaTIon) is a communication technology that uses radio signals to identify specific targets and read and write related data without the need to identify mechanical or optical contact between the system and a particular target. In fact, RFID is very familiar to everyone, and the various access cards we use are based on this technology. RFID has ETC, parking lot, parking space guidance, special vehicle management, etc. for vehicle assisted or managed systems.
ITS (Intelligent Transport System) is the development direction of the future transportation system. It is the effective integration of advanced information technology, data communication transmission technology, electronic sensing technology, control technology and computer technology into the entire ground traffic management. A comprehensive, real-time, accurate and efficient integrated transportation management system that works in a wide range and functions in a comprehensive manner. ITS can effectively utilize existing transportation facilities, reduce traffic load and environmental pollution, ensure traffic safety, and improve transportation efficiency. The 21st century will be the century of intelligent road traffic. The intelligent transportation system that people will adopt is an advanced integrated transportation management system.
Summary: For the update of the Internet of Vehicles, the domestic market is still dominated by the future, but the products are scattered. The pre-installation industry also felt that the huge business opportunity of the Internet of Vehicles began to gradually develop and update products. For example, OnStar, GBook, Ford Sync, BMW ConnectDrive, InkaNet.
The automotive aftermarket itself is also an important part of the automotive industry chain, including financial and insurance services, car rental, repair and maintenance, parking lots, rescue systems, traffic information services and used cars.
However, in recent years, with the outbreak of big data on the Internet and the continuous updating and new development of high-tech products, Internet technology companies have begun to change from the role of service providers to the role of developers, leading to the traditional industry chain and the traditional car networking ecosystem. Including car manufacturers, spare parts suppliers, after-installers, telecom operators, map suppliers, service providers and other quality reforms and innovations.
If you really realize the ideal Internet of Vehicles, you will eventually have to connect the complex relationship between cars and cars, cars and people, cars and roads, not only the strong alliance between car companies and Internet technology companies, but also the government. Planning and government support and participation can be integrated.
The Internet of Vehicles is very large and convenient, and the future development prospects are good, but at present it can only achieve a very simple part. Therefore, the future of the Internet of Vehicles is long and difficult, and it is necessary to work hard!
