Speed limit control method based on cooperation of signal and braking system

The invention discloses a speed limit control method based on cooperation of a signal and a braking system, and the method comprises the following steps: vehicle-mounted ATO equipment calculates the distance and speed curve of a target parking point according to the current train position and the position of the target parking point; the vehicle-mounted ATO equipment informs a vehicle traction braking system of the target parking point information and triggers a low-speed operation instruction; the vehicle traction braking system calculates a traction braking level according to the target speed and the target distance and controls the train to move at a low speed; and the train stops at the target parking window, and the low-speed operation instruction is cancelled. According to the method, target point parking control at a low speed is completed, low-displacement parking control is facilitated for a short-distance low-speed operation scene, and constant-speed control of the train speed is facilitated for a l
