A method for controlling a braking system controlled friction against slipping of a railway vehicle

摘要

Method for controlling an emergency brake (1) of a rail vehicle or train of rail vehicles comprising several rail vehicles, which presents a number of braked axles through friction brakes where emergency braking starts through a request for emergency braking, which comprises at least the following steps: a) identifying at least one axis having a sliding inadmissible braking during emergency braking, where slippage inadmissible braking presents by out of a sliding range of predetermined optimum braking, b) identifying at least one axis does not have a sliding brake or having a sliding permissible braking during emergency braking, through which can be passed a braking force higher friction through at least one axis having a sliding inadmissible braking c) adaptation forces friction braking to at least one axis does not have a sliding brake or having a sliding permissible braking, so that through at least partial compensation of the braking force by lost friction due to sliding inadmissible braking at least one axis, a deviation of the actual deceleration of the rail vehicle or train of rail vehicles, with respect to a desired deceleration predetermined through application emergency braking it can be maintained within a range tolerable by such adaptation.
