A method and a device for controlling an inverter of a vehicle, and such a vehicle are disclosed. The method includes: ascertaining information concerning a heating requirement of a battery of the vehicle; controlling the inverter in a first mode in which current provided by the battery flows through an electric motor of the vehicle; and controlling the inverter in a second mode which represents freewheeling of the inverter, in which freewheeling current flowing through inverse diodes of semiconductor switches of the inverter leads to the heating of the battery. A repeated switchover is made between the first mode and the second mode. An average current flowing through the electric motor corresponds to a DC current which does not cause any torque in the electric motor. Respective switchover points in time between the first mode and the second mode are defined according to the heating requirement of the battery.
