  • Patent number: 10906516
    Abstract: Provided is a brake control system that can reduce use of a mechanical braking in a railway vehicle using an automatic train control (ATC). The present disclosure is a brake control system for a railway vehicle using an ATC. The brake control system includes: a main electric motor, a main conversion device, a brake controller, and an ATC device. The main electric motor generates a braking force by converting kinetic energy of a wheel of the railway vehicle to electrical energy. The main conversion device actuates the main electric motor. The brake controller outputs a braking signal to the main conversion device. The ATC device outputs a braking command to the brake controller based on the ATC. In addition, the ATC device outputs a preliminary braking signal for energizing the main electric motor prior to output of the braking command.
