A method and a device for planning a path when parking a vehicle (02) are described, in which a path (01) which comprises a first and second path arc (03; 04) is calculated on the basis of the geometry of a parking space (05) and a vehicle position relative to this parking space (05). According to the invention, at first a minimum appropriate first path arc (08) of the path (01) is calculated in order to reach a starting position as early as possible, and subsequently a possible larger first path arc (09) of the path (01) is preferably calculated as a function of an actual stopping position (13) of the vehicle (02). Furthermore, a driving assistance device for carrying out the method is described, as well as a computer program product which causes a microprocessor with associated storage means to carry out the method.
