Abstract: The invention relates to an apparatus for finding a parked vehicle again. According to the invention, a portable unit is provided with a pressure sensor whose signals can be evaluated by an evaluation and control unit in order to determine the current air pressure, with the evaluation and control unit evaluating the determined air pressure in order to determine altitude, and storing a first air pressure value as a reference value at a predeterminable first time, which reference value represents an instantaneous altitude of a geographic position of the parked vehicle, with the evaluation and control unit estimating a height difference between a current geographic position of the portable unit and the geographic position of the parked vehicle at a second time, and/or continuously from a pressure difference between the determined current air pressure value and the reference value.

Abstract: Method for finding a vehicle (2), wherein a direction information item relating to the position of a mobile terminal (P2) with respect to the position (P1) of the vehicle is derived by comparing satellite supported position coordinates (P1, P2), and the respective direction information item is output by means of a display unit which is integrated into the mobile terminal (4), the geographic position (P1) of the vehicle (2) is stored in the mobile terminal (4) in the form of position coordinates when the vehicle (2) is deactivated, wherein if the mobile terminal (4) is in a second zone (Z2) surrounding a first zone (Z1), the current coordinates of the geographic position (P2) of the mobile terminal (4) are compared with the stored position (P1) of the vehicle, and if the mobile terminal (4) is in the first zone (Z1), the coordinates of the position (P1) of the vehicle are interrogated from the vehicle on an updated basis by means of a satellite supported position determining system, and this position (P1) of t
