Abstract
An anti-blocking system for a vehicle having an electromotive vehicle drive unit includes one or more driving motors. During a braking process, the braking effect of the driving motors operating as a generator is limited in such a way that brake slip on at least one driving wheel is limited to a predefined threshold value. The rotational speed of each driving motor is regulated by a controllable converter associated therewith, the ABS control device constantly transmitting, to each converter, a mandatory minimum braking rotational speed for the driving motor associated with the respective converter in order to limit brake slip.
