What parts does the engine electronic control system consist of

[Answer]: Electronic control The system generally consists of three parts: Sensors, Electronic Control Unit (ECU) and Actuators.

The electronic control system is mainly composed of sensors, control units and actuators. The core component is the control unit. Signal input device: various sensors, collect the signals required by the control system, and convert them into electrical signals and transmit them to the ECU through the line.

The engine electronic control system is composed of an electronic control unit (ECU), a sensor and an actuator.The three components have different functions. They have developed from ordinary electronic control to microcomputer control, and have been combined into a comprehensive control system.

How is the development trend of the electronic control system of automobile engines in recent years?

1. The proportion of electric drive systems in the cost of new energy vehicles is second only to batteries. The electric drive system (motor, electronic control, reducer) is the key component of the powertrain of new energy vehicles, which is equivalent to the role of the traditional fuel vehicle engine, which directly determines the power performance of the whole vehicle.

2. Technological innovation will bring about a new revolution in the automobile industry. After continuous enrichment and supplementation, major countries around the world have formed a relatively perfect system of new energy vehicle purchase subsidies, promotion and use, supporting facilities construction and policy support.The construction of the automobile industry cluster system will be more and more perfect. The layout of the domestic automobile industry will be basically completed.

3. By 2025, the competitiveness of China's new energy vehicle market will be significantly enhanced. Major breakthroughs will be made in key technologies such as power batteries, drive motors and vehicle operating systems, and the safety level will be comprehensively improved.

4. In recent years, the maturity of embedded system, local area network control and data bus technology has made the integration of automotive electronic control system an inevitable trend in the development of automotive technology.

5. This exhibition is mainly aimed at the Beijing-Tianjin-Hebei region. It is a professional B2B trade exhibition in the field of automobile aftermarket, which focuses on displaying the latest technologies and products in the field of automobile maintenance, testing and diagnosis equipment, parts and beauty maintenance. It is suggested that you can visit when you have time. Many industry practitioners will go to the site.
