Which technology is used in autonomous driving?

[Lacey]

Autonomous driving itself is a technology, which is divided into several levels, each with different principles and technologies employed. Autonomous driving requires four steps to complete: information collection, analysis and recognition, action decision-making, and device control. Below is a detailed description: 1. The autonomous driving system utilizes advanced communication, computer, network, and control technologies to achieve real-time and continuous control over trains. By employing modern communication methods, it directly interfaces with the train, enabling bidirectional data communication between the train and the ground. This ensures fast transmission rates and large data volumes, allowing subsequent tracking trains and control centers to promptly obtain the exact position of the preceding train. This makes operational management more flexible, control more effective, and better suited to the requirements of train autonomous driving. 2. The main functions of the autonomous driving system are bidirectional information transmission between the ground and the train, as well as comprehensive and emergency handling of operational organization. The ground-train information transmission channel is a crucial component of the automatic train operation control system. The onboard equipment of the automatic control system relies entirely on operational control commands received from the ground control center to operate the train. It continuously monitors the train's actual speed and the ground's permitted speed commands. If the train speed exceeds the ground's operational speed limit, the onboard equipment will implement braking to ensure the train's operational safety.
