Abstract

A method for the drive coordination of a rail-guided vehicle with individual-wheel drive traveling on straight track, including the steps of determining a differential speed (&Dgr;n) of opposite track wheels and a control value (&Dgr;M) by a controller as a function of a set point, whereby the set point is ideally zero and the frequency and the damping of the control value (&Dgr;M) can be dynamically adjusted by controller parameters. The invention further comprises a method for the drive coordination of a rail-guided vehicle with individual-wheel drive, in particular when the vehicle is traveling over curves, in which at least one axle is fastened so that it can rotate with respect to the underbody, whereby the angular position (&ggr;st) of the axle with respect to the underbody is regulated so that the track wheels are tangential to the rail by setting the angular position (&ggr;sl) of the axle by means of the torque set points (MSet,l MSet,r) of the individual wheel drives. This invention further comprises a combination of the two methods described above, whereby the axle is fixed by arresting means as a function of the radius of the curve.
