Title: (EN) Method for controlling an antiskid-regulated friction brake system of a rail vehicle
Abstract: front page image
(EN)

A method for controlling an emergency brake device of a rail vehicle or rail vehicle train consisting of several rail vehicles having axles braked by friction brakes, wherein an emergency braking operation is started by an emergency braking input, including identifying at least one axle having inadmissible brake slip during the emergency braking operation in which inadmissible brake slip occurs outside a predetermined optimal brake slip range; identifying at least one axle having no or admissible brake slip during the emergency braking operation by which axle a larger friction braking force can be transferred than by the at least one axle having inadmissible brake slip; and adjusting the friction braking forces on the at least one axle having no or admissible brake slip such that the adjustment can maintain a deviation of the actual deceleration of the rail vehicle from a target deceleration.
