Abstract
A method for operating a motor vehicle, including an electric machine and a coupling device, which, in a first coupling state, couples the electric machine to a drivetrain and, in a second coupling state, decouples the electric machine from the drivetrain, wherein the method includes the following steps: a) registering an item of coupling information, which specifies whether the coupling device is in the first or second coupling state, b) analyzing a recuperation condition, the fulfillment of which is dependent on the coupling information, wherein the recuperation condition is fulfilled or can only be fulfilled if the coupling device is in the second coupling state, and c) braking the electric machine by operating the electric machine as a generator if the recuperation condition is fulfilled.
