| description | A traction control system, in particular a method for traction control for a rail vehicle is disclosed, which method predefines a torque setpoint value (M
setp
) for a motor control unit, embodied as a torque control unit (
3
), by means of a wheel-slip control unit (
1
) and reduces the torque setpoint value (M
setp
) by means of the wheel-slip control unit (
1
) when a predefinable threshold value of a differential rotational speed value ( n), formed from a present rotational speed value (n) and a calculated reference rotational speed value, of a drive motor of a wheel set is reached. In addition, a stator frequency value (f
S
) is predefined for at least one drive motor, embodied as an asynchronous machine, of a wheel set of the rail vehicle, the stator frequency value (f
S
) being limited to a stator-frequency-dependent limiting value (f
SG
) when a maximum frictional engagement between the wheel set and rail is reached. In addition a device for carrying out the method is disclosed. P112017 |
