Abstract

An electronic control unit is provided for automatically activating a parking brake in dependence of at least one specified operating parameter or operating mode of a motor vehicle, which can be started without a mechanical key. The operating mode for the basic automatic activation of the parking lock is the fact that the internal combustion engine is shut off.
