Abstract

A motor vehicle has an electronically controllable parking lock and an electronically controllable parking brake, which can be controlled individually or in combination. A device having an electronic control unit and a central operating element associated with the parking lock and the parking brake is provided. When the motor vehicle is at a standstill and the central operating element is actuated, the parking lock and the parking brake can be controlled in a specific type of parking-lock and/or parking-brake activation. In a first specific type, during a first actuation of the central operating element, at least the parking brake is automatically activated first. If the central operating element is then re-actuated within a predefined time window, or if the central operating element remains actuated for a predefined minimum time period, the driver is offered at least one possibility of manually selecting a specific type of parking-lock and/or parking-brake activation.
