What are the self-driving cars? ,

As the protagonist of this L3 road test, Changan Automobile has no doubt about the research level of autonomous driving. As early as two years ago, at the Zhibo Fair, Changan Automobile demonstrated the L4-class self-driving Yidong EV460 model, which was at the forefront of the industry.

Since then, with the launch of changan CS55, Chang 'an has become a veritable "first brother" of self-driving brand. This model combines low price and high intelligence, and it is also the first self-owned brand model equipped with L2 automatic driving system.

The induction hardware of IACC system carried by changan CS55 is camera+millimeter wave radar, similar to Tesla. At present, this system has been honed for two years, and its safety performance has been guaranteed.

2. Geely Yue Bin

Following Chang 'an, Geely, another domestic manufacturer, also started to install L2-class autopilot system on its own models. The first two models to benefit are naturally Binrui and Yue Bin.

As two models for young consumers, their shapes are trendy enough. Obviously, L2 autopilot is another big selling point. Take Yue Bin as an example, it can realize ACC adaptive cruise in full speed range. AEB-P urban pre-collision system can identify vehicles and pedestrians over 80cm. With the cooperation of other ADAS systems, it already has L2-level automatic driving capability.

Precautions:

Although there are many kinds of vehicles, their structures are similar. This should be said to be the credit of standardization and the need of large-scale production line. With the development of society, the progress of science and technology and the change of demand, the appearance of railway vehicles has also begun to change, especially the passenger cars are no longer the same old faces. However, their basic structure has not changed obviously, but the specific parts have more scientific and advanced structural design.

Generally speaking, the basic structure of a vehicle consists of five parts: body, underframe, running gear, coupler buffer device and braking device. The car body is the part of the vehicle carrying goods or passengers, and it is also the basis for installing and connecting other parts of the vehicle. The bodies of early vehicles were mostly wooden structures, supplemented by steel plates and bow bars. Modern automobile body is mainly steel structure or light metal structure.
