A method and start-stop device for initiating an automatic shutdown of an engine, in particular a combustion engine, in a motor vehicle are provided, wherein an automatic shutdown of the engine is initiated if a condition triggering a stop has been met and no shutdown preventer has been met. A first condition triggering a stop is determined depending on a delay request, when with the triggered delay request a braking value is requested that exceeds a predetermined first shutdown braking threshold without exceeding a predetermined second shutdown braking threshold that is greater than the predetermined first shutdown braking threshold. A second condition triggering a stop is determined depending on a delay request, if with the triggered delay request a braking value is requested that exceeds the predetermined second shutdown braking threshold.

A motor vehicle includes at least one electric motor for driving the motor vehicle, at least one electrical energy storage device via which the electric motor can be supplied with electrical current, and a charging device having at least one coil via which electrical energy can be inductively transmitted for charging the electrical energy storage device. An internal combustion engine of the motor vehicle includes a reservoir in which lubricant for lubricating the internal combustion engine can be received and on which the coil, and optionally at least one electronics component associated with the coil, is arranged.

An electromechanical transmission for use with a motor vehicle having an internal combustion engine includes a planetary gear assembly, an electric drive, a changeover gear assembly, and a driven shaft. A planetary gear assembly includes an input shaft and first and second output shafts, wherein the input shaft is coupled to a crankshaft of the internal combustion engine. The electric drive includes first and second rotors connected to two of the input shaft and two output shafts of the planetary gear assembly, respectively. A changeover gear assembly includes first and second gear shafts connected to the two output shafts of the planetary gear, respectively. The changeover gear assembly also includes a first gear wheel pair rotatably mounted to the first gear shaft and a second gear wheel pair rotatably mounted to the second gear shaft. The changeover gear assembly further includes a shifting mechanism operatively associated with each gear shaft and the corresponding gear wheel pair. A driven shaft is coupled to each of the gear shafts via gear engagement.
