Method for operating a motor vehicle, device for a motor vehicle, motor vehicle

The invention relates to a method for operating a motor vehicle (1) which has an electrical machine (7) with at least three phases, an electrical energy store (13) and a power electronics system (12) having a plurality of switching elements, wherein the switching elements of the power electronics system (12) are actuated for electrically connecting the phases to the energy store (13), in order to produce a generator deceleration moment. Provision is made for a driving situation of the motor vehicle (1) to be determined, wherein an actuation method is selected from amongst a group of at least two possible actuation methods according to the determined driving situation, and wherein the switching elements are actuated according to the selected actuation method.
