    • 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.
    • 本发明涉及一种再次找到停放车辆的装置。 根据本发明,便携式单元设置有压力传感器,其信号可以由评估和控制单元评估,以便确定当前空气压力,评估和控制单元评估确定的气压以便确定高度 并且将第一空气压力值作为参考值存储在可预定的第一时间,该参考值表示停放的车辆的地理位置的瞬时高度,评估和控制单元估计当前地理位置之间的高度差 所述便携式单元和所述停放的车辆的地理位置在第二时间,和/或连续地从所确定的当前空气压力值与所述参考值之间的压力差。
