Have you ever thought about having such a car: it will automatically open to your downstairs when you start work at 8:00 in the morning, automatically check the traffic conditions of each section in real time, avoid the congested sections, and deliver you to the working place on time. . Because it is powered by a battery, there is no pungent smell of gasoline. When the battery is low, it will look for the nearest charging station and complete the charging quickly.

With the advancement of automotive electronics technology, the degree of intelligentization of automobiles is greatly increasing. Taking the hot auto driving as an example, it has attracted the participation of technology giants including Google, Apple and Baidu, and promoted the rapid development of automotive electronics technology. Cars are rapidly gaining popularity, and the focus on cars has also changed from "car shape" to smart cars, not only to enjoy the speed and passion of driving, but also to enjoy the joy and comfort of driving.

Vehicle network development trend forecast

In recent years, the Internet of Vehicles has become a hot word in the industry. Since 2010, the Internet of Vehicles market is growing at a rate of 20%-60% per year. By 2020, the number of vehicles linked through the Internet of Vehicles may reach 200 million. The market size is about 200 billion. The car network covers a wide range, mainly including four aspects: the connection between the car and the car, the connection between the car and the person, the connection between the car and the road, and the connection between the car and the Internet.

It is reported that the concept of car networking originates from the Internet. The Internet refers to the interconnection of two computers or more computer terminals, clients and servers through computer information technology. In contrast, the car network is just changing nodes. It has become an in-vehicle electronic device such as an in-vehicle computer ECU, which is connected by a mobile communication network. The eco-chain of the Internet of Vehicles is extremely extensive, including logistics, passenger and cargo, 4S stores, vehicle insurance, maps and navigation, emergency rescue, car e-commerce, Internet applications and so on. At present, the Internet, especially the mobile Internet, has penetrated into all aspects of social life. The connection between the car and the Internet is bound to bring another profound change. The car itself will serve as a good carrier, in addition to accepting peripheral services such as car repair, maintenance and insurance. It will also cover all aspects of food, clothing, housing and transportation.

Advanced Driver Assistance System (ADAS)

Many technology giants have contributed to the situation, and automatic driving has continued to grab the headlines. However, it takes time to achieve automatic driving, and the automatic driving core technology driving assistance system is developing rapidly. Driving safety is a problem that every car owner pays attention to. Driver assistance systems can prevent problems before they occur, and minimize safety hazards. Today, as car products become more and more homogenous, ADAS will also realize product differentiation. a powerful weapon.

At present, the functions of the mainstream advanced driving assistance system (ADAS) can be roughly divided into blind spot monitoring, road departure warning, automatic emergency braking, lane change assistance, fatigue warning and 360° panoramic camera monitoring to assist driving and reduce The main cause of road traffic accidents. With the increase in the popularity of ADAS, traditional cars will initially have semi-automatic driving kinetic energy, laying a solid foundation for the commercialization of driverless cars in the future.

The information required by the car, such as the running state of the vehicle, the driving control state, the vehicle control situation, the operating environment, the abnormal state, etc., are mostly obtained by sensors. As an important source of information for automotive electronic control systems, automotive sensors are widely used in automotive engine management, power drive and safety and comfort systems. The number and level of sensors also determine the level of modern automotive control systems. It is the "probe" of the electronic control system. The more you use it, the more comprehensive the electronicization of the car and the higher the degree of automatic control.
