Method and apparatus for detection and correction the wheel slip of a rail vehicle

Abstract

Abstract 1. A method of detecting and correcting the slipping of the wheels of at least one axle of a railway drive vehicle, in which the acceleration (gamma 1, gamma 2) of the axles (1, 2) is measured to provide a signal controlling the traction force by acting on the drive means (H) of the drive vehicle, characterised in that the following operations are carried out : a) the acceleration derivative (dgamma 1/dt, dgamma 2/dt) of each axle is determined ; b) a detection signal (D1, D2) is prepared for each axle, such signal being a linear combination of the acceleration and of its derivative ; c) partial correction signals (COR1 , COR2) are prepared which increase as a function of each respective detection signal (D1, D2) ; d) the larger of the partial correction signals is determined to form a common correction signal (COR) ; e) a signal (DF) is calculated representing the difference between the correction signal (COR) and a reference value (C) ; f) the traction is regulated by acting on a drive means (H) of the drive vehicle as a function of the difference signal (DF).
