摘要

safety device for a rail vehicle, rail vehicle, method for preserving safety of such rail vehicle and associated computer program. The present safety device (24) for a rail vehicle (2) is configured to control a rail vehicle braking system (22). comprises a first sensing module for detecting at least abnormal behavior of the railway vehicle between a prohibited light signal crossing (10, 11) and exceeding a speed limit; a second detection module for detecting at least one internal safety device failure, and a control module for sending a command signal to the braking system. The control module is configured to: - If abnormal behavior is detected, send a command signal for emergency braking according to a first level of braking, and - If an internal fault is detected, send a command signal for braking. according to a second braking level, the first level being greater than the second level.
