The invention relates to a method for determining the remaining time an electric drive runs until it reaches a mechanical stop, said drive being used to displace surfaces to be closed by means of the drive to their mechanically limited final positions. Once the position of the surface to be closed relative to a mechanical stop is determined the time difference between two incremental indicator pulses (25) in the vicinity of the stop is determined and the remaining time (26) is calculated until the electric drive reaches the mechanical stop.
