The key supporting role of automobile parts in intelligent d

With the rapid development and innovation of science and technology, autonomous driving technology has gradually become the new focus of the automobile industry. In the process of achieving this goal, automobile parts play a vital role. From sensors to actuators, every link plays a key role in improving the safety, comfort and efficiency of vehicles.

First, perceive the environment

In the automatic driving system, the first problem to be solved is how to make the car "see" the surrounding environment. This mainly depends on many types of sensors. Commonly used are LIDAR, millimeter wave radar, camera and so on. They can provide information about the distance, speed and shape of obstacles, and provide an important basis for subsequent decision-making. Among them, lidar can generate high-precision three-dimensional point cloud images to help identify pedestrians and non-motor vehicles; The camera uses image processing algorithms to identify visual elements such as facial expressions and traffic signs.

Second, the computing platform

After collecting enough data, a powerful computing platform is needed for analysis and processing. This process involves complex mathematical operations and the application of deep learning model, which requires the hardware to have a very high computing power level. At present, the mainstream scheme is to adopt GPU+FPGA or ASIC architecture to meet the real-time requirements and ensure the reasonable and controllable energy consumption. In addition, in order to ensure the safety of driving, redundant backup mechanism should be considered in the design to prevent the failure of the whole system caused by a single point of failure.

Third, control execution

The last step is to make corresponding action instructions according to the calculation results, such as accelerating and decelerating, turning and changing lanes. This involves motor drive, accelerator pedal simulation and many other aspects. Especially for the drive-by-wire chassis, its accuracy directly affects the driving experience. Therefore, in the process of research and development, we must strictly abide by the relevant standards and specifications, and fully test and verify them before putting them into use.

To sum up, every kind of automobile parts plays an irreplaceable role in promoting the progress of intelligent driving technology, whether it is sensing the external environment or internal operation control. In the future, new materials and technologies will continue to emerge, and it is believed that more efficient and reliable products will come out to help create a smarter and more convenient travel life.
