What does the engine electronic control system include?

Automobile electronic control system can be divided into the following four parts:

Centralized control system for engine and power transmission.

Integrated chassis control and safety system.

Intelligent body electronic system.

Communication and information/entertainment systems.

Principle and development trend of electronic control system of automobile engine;

1, Engine Electronic Control System (EECS) electronically controls engine ignition, fuel injection, air-fuel ratio, exhaust emission, etc. Therefore, the engine can work in the best working condition, so as to improve its vehicle performance, save energy and reduce exhaust emissions.

2. Automotive electronic control technology has become an important symbol to measure the development level of modern automobiles. The automobile electronic control system is obviously developing towards integration, intelligence and networking.

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.
