Abstract

1. Method for the regulation of the driving or braking force of the traction motors (2) of dead-axle-free electrical traction vehicle at the static friction limit of the wheels with the use of an equipment (13), which integrates the acceleration or deceleration to be expected and the output magnitude of which by difference from the actual rotational axle speed is evaluated as measure of the wheel slip for reduction of the driving or braking moment, as pseudo-dead-axle, wherein the output signal of the integrating equipment is in the slip-free operation made to follow the actual rotational axle speed by way of a regulating circuit (14 to 18) acting on a further input of the integrating equipment (13), characterised by the following features : - the first time derivative of the rotational speed difference between pseudo-dead-axle and actual axle see diagramm : EP0159284,P6,F1 is formed in a differentiator (22) and a limit value stage (28) is driven thereby, the output of which imposes an additional input magnitude on the integrator (13) of the pseudo-dead-axle, - the additional input magnitude due to an inverter (34) has a sign opposite to the acceleration or deceleration control magnitude conducted to the integrator (13) and according to magnitude influences the direction of integration or halting of the integrator (13), - after a delay time formed by a timing member (30), an inverter (24) is connected between the differentiator (22) and the input of the limit value stage (28), - the limit value stage (28) has a relapse delay due to a feedback path (29), and - the delay time of the switching-in of the inverter (24) and the relapse delay of the limit value stage (28) are matched to the dynamic behaviour of the drive in such a manner that a gap between the appearance of the positive and the negative output signal of the differentiator (22) is filled on the modulation of the limit value stage (28).
