An emergency braking control circuit based on coupler coupling detection includes a coupler status detection circuit and a coupler status relay that are connected in series with a train power loop. A normally open contact of the coupler status relay is connected to an emergency braking train line in a cross-parallel manner. When a coupler is coupled normally, inductive proximity sensors located at a knuckle and a central pivot are closed to drive the coupler status relay, and the normally open contact of the coupler status relay is connected in a cross-parallel manner to ensure that a corresponding node of the emergency braking loop is closed. In case of abnormal coupling or accidental uncoupling of couplers, the inductive proximity sensors of the couplers of two adjacent cars are disconnected simultaneously, the coupler status relays of the two cars are powered off, and emergency braking is applied.

A method for operating a braking system, wherein a switchable connection between two connection points is open in normal operation, and a voltage difference across the switchable connection is reduced by recuperation before said switchable connection is closed, which serves to compensate for a disturbance in an on-board electrical system. As a result, it is possible to avoid excess currents in the event of the closing of the switchable connection.
