A method (100) for operating a vehicle (1) with an electric drive-train (2), wherein this electric drivetrain (2) is fed via a DC voltage source (3) and a converter (4) for converting the DC voltage into a single-phase or multiphase AC voltage, comprising the steps: —it is detected (110) that the vehicle (1) is stopped; — it is checked (120) on the basis of at least one specified criterion (10) whether the vehicle (1) is expected to be stopped only briefly; —in response to the fact that the vehicle (1) is expected to be stopped only briefly, the vehicle (1) is transferred (130) from the ready-to-drive state into a disabled state, wherein in this disabled state the vehicle (1) is protected against unauthorized use but the converter (4) continues to be supplied with the DC voltage from the DC voltage source (3); —in response to the fact that the vehicle (1) is not expected to be stopped only briefly, at least one functional test of the electric drivetrain (2), said test being provided for powering down the electric drivetrain (2), is performed (140), and after the termination of this functional test the vehicle (1) is transferred (150) into a switched-off state, in which the vehicle (1) is secured against unauthorized use and the supply of the converter (4) from the DC voltage source (3) is interrupted.
