一种减速度闭环控制方法及装置

The application provides a deceleration closed-loop control method and device, which relate to the field of railway vehicle mechanical control and comprise the steps of determining the brake cylinder pressure of a railway vehicle brake system by utilizing a pre-constructed friction coefficient calculation model when the difference between the required deceleration in a brake instruction and the actual deceleration of the railway vehicle is larger than a preset threshold value; the braking system comprises a brake cylinder, a brake cylinder pressure sensor and a brake cylinder pressure sensor, wherein the required deceleration is sent by an automatic driving system, the actual deceleration is obtained by actual measurement, and the brake cylinder pressure is acted on the brake system to realize deceleration closed-loop control. The application can acquire the current deceleration state of the train in real time and compare the current deceleration state with the target deceleration, thereby adjusting the pressure of the brake cylinder in real time to improve the deceleration efficiency.
