And to understand the current situation of the automotive maintenance industry from the perspective of more modern maintenance equipment and more electronic maintenance objects. This article elaborates on the development of automotive maintenance in China from the perspective of automotive electronic control technology, focusing on strengthening the use of detection equipment, emphasizing the application of maintenance data, and improving the comprehensive quality of technical personnel, making contributions to the innovative development of the automotive field.
1 Application of Automotive Electronic Control Technology in Automotive Systems
1.1 Steering control system
In the steering control system of automobiles, electronic control technology can use real-time vehicle speed data collected by sensors to control solenoid valves to make corresponding operations. This is because the computing center can analyze the current wheel speed and actual operating angle of the steering wheel through data signals, and quickly calculate the direction and rotation angle of the front and rear wheels that need to be braked.
As an important information foundation and key component of electronic control systems, automotive sensors can convert non electronic signals generated during driving into electronic signals, which is beneficial for the detection system to perform timely calculations and analysis.
For example, when a car is driving at high speeds, the car's electronic control technology can control the rear wheels to turn in the same direction, reducing the pressure on the steering wheel for the driver and making the steering operation easier. At the same time, it greatly improves the steering performance when the vehicle is moving at high speeds; When the speed of the car gradually decreases or stops, the car's electronic control technology can make the front and rear wheels rotate in the opposite direction, effectively increasing the assistance while reducing the turning radius in a timely manner.
1.2 Variable speed control system
With the innovative development of scientific and technological means, many automobile manufacturers have merged the controllers of engines and transmissions together. This not only greatly reduces the number of interfaces and line speeds, thereby saving equipment space, but also achieves higher automotive equipment performance at a lower cost.
Automotive electronic control technology can save energy consumption and import green and environmentally friendly driving states into the computer center. Therefore, when the car is driving, it can automatically calculate and analyze the suitable gear based on information such as car speed and engine status, and feedback it to the effector to achieve variable speed shifting function. Therefore, the application of automotive electronic control technology in the transmission control system can provide more sufficient power when the car is driving on complex roads, reducing the number of times the driver changes gears and saving fuel consumption.
1.3 Drive control system
The function of the drive control system is to avoid the phenomenon of sliding of the driving wheels during the driving process of the vehicle, and when the vehicle is turning, it is greatly affected by centrifugal force, resulting in a longer sliding distance of the driving wheels than the driven wheels, which weakens the braking and handling performance of the car. For example, in winter when the road surface freezes, the wheels will have a noticeable slip when the vehicle starts or accelerates. Even if the wheels have a fast speed at this time, their driving force is greatly affected.
A relatively stable drive control system can ensure that the wheels roll and slide. When the vehicle applies emergency braking, if the front tires lock up, it will be difficult for the driver to turn, and if the rear tires lock up, it will be extremely easy to slide sideways. At this point, it can increase the friction between the wheels and the ground, greatly reducing the braking distance while ensuring stable braking of the vehicle.

Combined with the information input by the driver, it can intelligently select and navigate the driving route.
2.2 integrated
The integration of automotive electronic control technology combines the engine management system and automatic transmission control system into a comprehensive system for automotive power transmission control, relying on mature data bus technology and local area network technology. At the same time, anti-skid drive, traction drive, anti lock braking and other systems will be integrated into the overall braking control system.
For the chassis control system of automobiles, it is based on data bus technology to connect power transmission, steering, suspension, braking devices and other equipment together, and processes data through its central chassis controller to adjust the overall attributes of the vehicle to a high level.
2.3 networked
Due to the increasing use of electronic control devices in automobile manufacturing, the electronic network systems used in automobiles are based on distributed control systems. Therefore, the rapidly developing information technology has put forward requirements such as low cost, strong interactivity, and convenience for automotive electronic interaction systems. It is crucial to do a good job in exchanging data information between vehicle electronic facilities.
In the production design, system control, and maintenance management stages of the automobile production process, there are requirements that belong to their own stages. This requires technical staff to fully understand and master these key points of information. However, due to the large amount of information that needs to be mastered, and the constant occurrence of technical personnel's unclear understanding of professional knowledge and skills and insufficient experience in the automobile maintenance process.
In order to solve these problems, it is necessary to give full play to the role of Internet information technology. Supported by a strong network, some very important maintenance information should be scientifically managed to ensure its accuracy at all times.
