3 Application analysis of intelligent automation technology in automotive engineering
3.1 Application in the overall design of automobiles
From the perspective of the overall industrial chain of automotive engineering, the core position is automotive R&D and design. Nowadays, the development of related science and technology has gradually narrowed the gap in the quality of automotive products, which has also led to a certain degree of automotive evaluation standards. With the degree of change, automotive performance indicators are no longer the only evaluation criteria, and standards including automotive design aesthetics and comfort are also increasingly being valued. Under this circumstance, the design link of Hyundai Motor is the most critical link in the preliminary planning work of automobile manufacturers, such as positioning products and building product pedigrees. The application of intelligent automation technology can make the design of cars more refined, and the design effects of some original niche applications can be used on a large scale. For example, in the 2017 Nissan BladeGlider concept car, five sets of high-performance lithium batteries are installed under the rear seats of the car, and their output power reaches 220KW, and the two electric motors used for power supply have the largest power. The value is 130KW, making its torque reach an astonishing 700N/m, which has surpassed the torque of most high-performance V8 cars. At the same time, the total weight of this concept car is only 1300Kg, which can provide people with excellent driving pleasure. This type of concept car wants to rely solely on manual production to achieve the goal of mass production, which has a high degree of difficulty, mainly because various uncertain factors in the manual production process will bring certain factors to the manufacturing of the car. influences. Intelligent automation technology is used in the manufacturing process of automobiles. It is only necessary to input automobile production parameters into the production system to achieve the goal of large-scale automobile production. Under the premise of monitoring the entire production process, it can solve the problems in the production process in time. problem.
3.2 Application in car rearview mirror system
The application of intelligent automation technology in automobile rearview mirror system can be divided into the following two aspects: First, the application in the position follow-up system. This system can effectively feedback the actual position of the car. The relevant personnel can input different signals into the system and effectively separate the type of position control system. In this process, the input quantity is in a state of constant change, and the The related output will also fluctuate accordingly. It is necessary to effectively control the input and output according to a certain ratio to ensure the safe and stable operation of the system. In the process of designing internal power supply lines, designers can use reversible circuits to ensure that the entire position following system can rotate in two directions. The main purpose of this approach is to effectively eliminate the deviation of direction and position. Second, the application of the fuzzy control system allows the driver to see the driving situation of the car behind by observing the rear-view mirror, so as to ensure the safety of the entire driving process while adjusting the driving direction and speed in time. If you want to adjust the rearview mirror, you need to make corresponding considerations to the driver’s driving position, so as to fully ensure that the driver can effectively use the rearview mirror to observe the driving situation while the car is driving. Through the application of fuzzy control technology, it is possible to determine whether the number of positions is correct or not while setting the position, and then the setting value can be converted into an analog value through the converter. Driven by the motor, the rearview mirror Can realize free rotation. In the process of designing fuzzy controllers for designers, fuzzy chips are an important part of it. The main reason why fuzzy chips can be widely used in fuzzy controllers is that they have huge advantages in inference speed and accuracy. More effective realization of automation control goals.
3.3 Application in automobile brake system
The quality and performance of the brake system have an extremely important impact on the pedestrian safety of the car and surrounding roads.
