AI Technical Summary
Technical Problem
Existing rail transit vehicle braking systems still rely on air or hydraulic fluid, resulting in slow response and environmental unfriendliness, failing to meet the development needs of electrification and intelligentization.
Method used
An electromechanical braking control system is adopted, including a braking force management module, a drive control module, and a motor execution module. It directly converts and executes braking force through electrical signals, eliminating the dependence on air or hydraulic media, and integrates a local drive control module to reduce communication latency.
Benefits of technology
It improves braking response speed and environmental protection capabilities, enhances system safety and reliability, and achieves more efficient braking control.

Abstract
This application provides an electromechanical braking control system and method. The system includes: an electrically connected braking force management module, a drive control module, and a motor execution module. The braking force management module receives braking level commands from a vehicle management system, converts these commands into braking force signals, and sends the braking force signals to the drive control module. The braking force signals indicate the target braking force required for each bogie. The drive control module receives sensor signals from a sensor system, generates motor drive signals based on the sensor signals and the braking force signals, and sends the motor drive signals to the motor execution module. The motor execution module performs electromechanical braking control on the vehicle based on the motor drive signals, aiming for a target braking force. This application eliminates reliance on media such as air or hydraulic oil, improving response speed and environmental friendliness during braking.
