Method for determining a position of a mobile terminal in a vehicle, wherein the method comprises: - capturing a reference depth map using a capturing device, wherein the reference depth map indicates, for image points of a capturing range of the capturing device, in each case distance information between the capturing device and a surface of an object at the relevant image point, while the mobile terminal is not located in the capturing range, - capturing a current depth map using the capturing device, wherein the current depth map indicates, for image points of the capturing range, in each case distance information between the capturing device and a surface of an object at the relevant image point, while the mobile terminal is located in the capturing range, - determining depth differences for image points of the capturing range, wherein a depth difference for an image point is determined on the basis of the distance information of the reference depth map at the image point and the distance information of the current depth map at the image point, and - determining the position of the mobile terminal on the basis of the depth differences, - determining a touch of an operator control of the mobile terminal on the basis of the position of the mobile terminal, and - generating and outputting additional information related to the operator control on the basis of the determined touch or approach, - enabling a login process of the mobile terminal to an access point of the vehicle for mobile terminals depending on the position of the mobile terminal, wherein a position of the mobile terminal is determined to be near a surface of an object of the vehicle by processing a depth difference for an image point of the mobile terminal by means of an evaluation function, wherein the evaluation function indicates that the position of the mobile terminal is near the surface of the object of the vehicle when the depth difference has a value between a first predefined threshold and a second predefined threshold. - capturing a reference depth map using a capturing device, wherein the reference depth map indicates, for image points of a capturing range of the capturing device, in each case distance information between the capturing device and a surface of an object at the relevant image point, while the mobile terminal is not located in the capturing range, - capturing a current depth map using the capturing device, wherein the current depth map indicates, for image points of the capturing range, in each case distance information between the capturing device and a surface of an object at the relevant image point, while the mobile terminal is located in the capturing range, - determining depth differences for image points of the capturing range, wherein a depth difference for an image point is determined on the basis of the distance information of the reference depth map at the image point and the distance information of the current depth map at the image point, and - determining the position of the mobile terminal on the basis of the depth differences, - determining a touch of an operator control of the mobile terminal on the basis of the position of the mobile terminal, and - generating and outputting additional information related to the operator control on the basis of the determined touch or approach, - enabling a login process of the mobile terminal to an access point of the vehicle for mobile terminals depending on the position of the mobile terminal, wherein a position of the mobile terminal is determined to be near a surface of an object of the vehicle by processing a depth difference for an image point of the mobile terminal by means of an evaluation function, wherein the evaluation function indicates that the position of the mobile terminal is near the surface of the object of the vehicle when the depth difference has a value between a first predefined threshold and a second predefined threshold.
