Zusammenfassung:	A method and a drive control device for operating at least two electric drive machines in the event of a change in load of a vehicle. A first torque can be transferred to at least one wheel of a first vehicle axle by a first electric drive machine, and a second torque can be transferred to at least one wheel of a second vehicle axle by a second electric drive machine. Each torque is defined by an amount and by a direction. In the method, it is determined whether a change in load is pending within a first defined timeframe and, if this is affirmed, the second torque is set for a second definable timeframe with a direction which is set opposite a current direction of the first torque.
