Beschreibung
Zusammenfassung:	The invention relates to a method for controlling a wheel speed of a wheel of a drivable axle of a two-track vehicle with two drivable axles as well as to a corresponding vehicle, with the vehicle having a first drive motor for driving the first axle, a second drive motor for driving the second axle, a device for detecting driving state variables, and a control device. The method comprises the steps: Detecting an actual speed of the first axle, determining a target speed for the second axle as a function of the actual speed of the first axle, and controlling the second drive motor such that the determined target speed is achieved on the second axle. In order to determine the target speed, a synchronous target speed at which the same wheel circumferential speed is achieved on at least one wheel of the second axle as on the wheels of the first axle is determined as a function of the actual speed of the first axle. Subsequently, the target speed for the second axle is determined as a function of the determined synchronous target speed.
