On October 28, 2010, Baidu’s “Car Network†keywords were searched for the first time.
During the Guangzhou Asian Games from November 12 to 27, 2010, more than 80 Suzhou Jinlong smart buses equipped with G-BOS equipment were put into service. This is the first time that the “3G†bus has appeared in the history of the Asian Games. It marks the official development of the Internet of Vehicles technology. So what exactly is the Internet of Things?
The concept of the Internet of Vehicles extends from the Internet of Things. The definition of the Internet of Vehicles varies according to the industry background. The traditional definition of vehicle networking refers to the identification of electronic tags loaded on vehicles through wireless radio frequency and other identification technologies, so as to extract and effectively utilize the attribute information and static and dynamic information of all vehicles on the information network platform, and according to different functional requirements. A system that effectively monitors the operational status of all vehicles and provides integrated services.
With the development of the Internet of Vehicles technology and industry, the above definition can not cover the entire content of the Internet of Vehicles. According to the definition of the technical innovation strategic alliance of the Internet of Vehicles Industry, the vehicle network is based on the in-vehicle network, the inter-vehicle network and the vehicle-mounted mobile Internet, in accordance with the agreed communication protocol and data interaction standards, in the car-X (X: car, road, A large system network for wireless communication and information exchange between pedestrians and the Internet is an integrated network capable of intelligent traffic management, intelligent dynamic information services and intelligent vehicle control. It is the Internet of Things technology in the field of transportation systems. typical application.
On August 27, 2013, the “Technology Innovation Alliance for Vehicle Network Industry†initiated by the China Automotive Engineering Society was formally established in Beijing. The alliance consists of 30 units, including 15 automakers, covering automakers, mobile telecommunications carriers, hardware equipment manufacturers, software service providers and research institutes. The alliance aims to promote the application of vehicle networking technology to enhance the safety and economy of the car, in addition to the TeleemaTIcs in-vehicle application service by coordinating the strengths of related industries and coordinating research and development.
On January 22, 2015, Baidu officially announced that Baidu's car networking strategy will be officially released on January 27, 2015. At this point, the Internet giants including Tencent, Alibaba and Baidu all competed in the battle network system.
First, smooth and unobstructed and more convenient
Have you ever had such an experience: a small accident on the road, the traffic is blocked. However, in the era of car networking, each car has GPS positioning and an "eye", the car can upload the road condition to the traffic management department, and the cloud controls the traffic flow to carry out route planning to avoid traffic congestion.
Second, rest assured that driving is safer
Driving safety is our biggest concern. After the arrival of the Internet of Vehicles, the car can actively explore the surrounding environment through its own sensors. It can connect various types of traffic lights and other control signals in the city to realize automatic prompting and avoid danger. With the development of the Internet of Vehicles, it is not a dream to achieve zero traffic accident rate in the future.
Third, low carbon travel is more environmentally friendly
In the process of low-carbon society, the intelligent transportation brought by the Internet of Vehicles will become an important driving force for energy conservation and consumption reduction. It can undertake 20% energy-saving and emission reduction tasks, and the smooth traffic network composed of people, vehicles and roads will greatly reduce additional fuel consumption and pollution.
In fact, this is the purpose of the Internet of Vehicles: to improve travel efficiency, ensure driving safety and promote low-carbon environmental protection, enterprises and individuals can benefit.
Third, what is the use of car networking1, GPS global positioning system
Without much explanation, current car and mobile navigation is based on this technology. In the Internet of Vehicles, it is still responsible for providing accurate positioning of the car.
2. WCDMA/LTE mobile communication technology
Safe and high-speed mobile communication technologies such as 3G/4G provide the possibility for the fast-moving vehicle to access the Internet, and at the same time, it can bring huge benefits to mobile operators. As early as the GPRS era, General Motors had tried to build a car network, but the low network speed at that time led to a decline in service quality.
3, intelligent vehicle system
Intelligent vehicle systems are mainly responsible for human-computer interaction and information processing in the Internet of Vehicles. Fujian Auto Online Technology Co., Ltd. products include intelligent car integrated machine, intelligent navigation screen, smart rearview mirror, car alarm, intelligent driving recorder, etc., which are divided into industrial customized intelligent terminal products and vehicle networking service equipment. Close to the smartphone-like features and user experience.
4, ECU electronic control unit and OBD vehicle automatic diagnosis system
These two systems are still responsible for their own work in the Internet of Vehicles, that is, monitoring and diagnosing the running status of the vehicle. In-vehicle in-vehicle system can achieve incomplete control of the vehicle, such as intelligent parking (automatic identification of parking spaces entering or exiting), adaptive cruising (automatically maintaining a relatively fixed distance from the preceding vehicle during driving), active collision prevention system (Automatically apply braking force when an impending collision is detected).
