#CMT# #/CMT# The method involves determining the current values carried by an electric motor (M) of the mobile device as detection signals. The detection signals correlates to a parameter, particularly its level, with a movement of the mobile device in the respective surface area. The related current values are evaluated on the basis of a current target value corresponding to a certain surface configuration. #CMT# : #/CMT# An independent claim is also included for a device for controlling the speed of an electric motor in a mobile device. #CMT#USE : #/CMT# Method for controlling the speed of an electric motor in a mobile device. #CMT#ADVANTAGE : #/CMT# The detection signals correlates to a parameter, particularly its level, with a movement of the mobile device in the respective surface area and the related current values are evaluated on the basis of a current target value corresponding to a certain surface configuration, and hence enables to determine the surface configuration of a surface area, over which a mobile device is moved, in a simple and cost effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a device for controlling the speed of an electric motor in a mobile device.
