Vehicle On-board Controller (VOBC) system obtains drive operation and protection data through continuous, high-capacity, bidirectional train-trackside data communication. Utilizing high-precision train positioning and speed measurement technologies, the VOBC generates speed-distance curves based on routine restrictions, offering over speed and over distance protection. By calculating the optimal operating curve, it achieves automatic train protection and automatic driving, ensuring the goal of safety, efficient, energy-saving, and comfortable ride.
