In today's world, the important symbols to measure the advanced level and grade of automobiles are mainly the brand, appearance and electronic degree of automobiles. Automakers generally believe that increasing the number of automotive electronic devices and promoting automotive electronics is an effective means to capture the future automotive market. Automobile designers generally believe that the application of electronic technology in automobiles has become an important means for automobile design and research departments to consider automobile structural innovation. The gasoline engine uses electronically controlled fuel injection technology, which can precisely control the air-fuel ratio and realize closed-loop control. If a three-way catalytic converter is added, the harmful emissions of the gasoline engine can be reduced by more than 95%; the diesel engine uses high-pressure common rail electronically controlled injection Oil technology, which can precisely control the fuel injection volume and the fuel injection pressure of up to 160-200MPa, not only can reduce fuel consumption and emissions, but also improve power performance; the application of anti-lock braking technology in automobiles can make the vehicle run in wet or snowy conditions. The accident rate on the road is reduced by 24% to 28%.

Since the history entered the 21st century, domestic and foreign cars such as engine electronically controlled fuel injection technology, microcomputer controlled ignition technology, anti-lock braking technology and safety airbag technology have been widely used. In domestically produced mid-to-high-end cars, the average cost of electronic devices for each car has accounted for 30% to 35% of the cost of the entire vehicle. In some luxury cars, the cost of electronic products has accounted for more than 50% of the cost of the entire vehicle, and Always maintain the trend of increasing year by year.

(1) Motivation for the development of automotive electronic control technology

Automotive electronic control technology is the product of the combination of automotive technology and electronic technology. In the past half century, the driving force and reasons for the rapid development of automotive electronic control technology include two aspects: on the one hand, the global energy shortage, environmental protection and traffic safety issues have prompted the continuous improvement of automotive fuel consumption regulations, emission regulations and safety regulations; On the other hand, the level of electronic technology is constantly improving.

Fuel consumption regulations and emission regulations promote the development of automotive engine electronic control technology, and safety regulations promote the development of automotive chassis and body electronic control technology. With the continuous improvement of fuel consumption regulations, emission regulations and safety regulations, automotive engine fuel injection electronic control systems, anti-lock braking systems and safety airbag systems have become standard equipment for cars at home and abroad.

 (2) Development trend of automobile technology

Since the 1980s, the development of automotive technology has mainly been the development of automotive electrical technology, electronic control technology and body technology. Automotive electronic control technology has played a pivotal role in solving problems such as automotive fuel consumption, emissions and safety. Automobile electrification (ie, automation, networking and intelligence) is the only way for the development of automobiles in the 21st century.
