Embodiment Construction

[0032] figure 1 A system 10 for detecting the relative position of a mobile terminal 14 with respect to a vehicle 12 is shown. The vehicle 12 includes an evaluation device 20 which is designed to generate reference measured values ​​which relate to a predefined relative position of the calibration device 18 with respect to the calibration vehicle 16 , wherein the mobile terminal 14 is used As the calibration device 18 and the vehicle 12 is used as the calibration vehicle 16 . The predefined relative position of calibration device 18 (ie currently mobile terminal 14 ) with respect to calibration vehicle 16 (ie currently vehicle 12 ) is represented by the dotted-line representation of mobile terminals 14 , 18 .

[0033] Calibration device 18 can also be embodied as a separate reference device, which has the same structure as mobile terminal 14 . It can be provided that the calibration device 18 can be used to some extent as a master device for different mobile terminals. Thus...

Abstract

The invention relates to a method and a system for detecting a relative position of a mobile terminal device with respect to a vehicle. The invention relates to a method for detecting a relative position of a mobile terminal device (14) with respect to a vehicle (12). The method comprises the following steps: generating a reference measurement value, the reference measurement value concerning a pre-defined relative position of a calibration device (18) with respect to a calibrated vehicle (16); generating a position measurement value, the position measurement value concerning a current relative position of the mobile terminal device (14) with respect to the vehicle (12); and analyzing the reference measurement value and the position measurement value to detect the current relative positionof the mobile terminal device (14) with respect to the vehicle (12). The task of the invention is to provide the following possibility: minimum deviation is achieved during detection of relative positions of different mobile terminal devices with respect to a vehicle.

Description

technical field [0001] The present invention relates to a method for detecting the relative position of a mobile terminal device with respect to a vehicle and a system for detecting the relative position of a mobile terminal device with respect to a vehicle. Background technique [0002] In modern vehicles, it is already possible to use mobile terminals, such as smartphones, in order to lock or unlock the doors. Publication DE 197 12 911 A1 discloses a keyless entry system for a vehicle which is based on sensor data of a magnetic field sensor of the vehicle. Apart from this, a technique is known, for example from US 2014 / 0266594 A1, which allows a vehicle to be started with a portable device. [0003] In order to implement the functions described (Umsetzung) reliably and safely, it is necessary to detect the relative position of the mobile terminal with respect to (in Bezug auf) the vehicle. [0004] Vehicle entry systems using near field communication technology already b...
