Method for controlling an antiskid-regulated friction brake system of a rail vehicle

摘要

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.

1. A method for controlling an emergency brake device of a rail vehicle or of a rail vehicle train which is composed of a plurality of rail vehicles, which rail vehicle or rail vehicle train has a number of axles which are braked by friction brakes, wherein emergency braking is started by an emergency braking request, the method comprising:
using an evaluation unit to identify at least one axle which has inadmissible brake slip during the emergency braking and at which inadmissible brake slip occurs outside a predefined optimum brake slip range, using the evaluation unit to identify at least one axle which has no, or admissible, brake slip during the emergency braking and by which a larger friction braking force can be transmitted than by the at least one axle with inadmissible brake slip, under control of an electronic control unit that actuates the brake actuator or the brake actuators at the at least one axle, adapting the friction braking forces at the at least one axle which has no, or admissible, brake slip such that, by at least partially compensating the friction braking force which is lost at the at least one axle owing to the inadmissible brake slip, a deviation of the actual deceleration of the rail vehicle or of the rail vehicle train from a setpoint deceleration predefined by the emergency braking request is kept within a tolerable range.
