Abstract: A mobile user terminal and method for activating/deactivating geopositioning devices of the mobile user terminal in moving vehicles, the mobile user terminal comprising accelerometers but no gyroscopes. The method detects whether a geopositioning device is located in a moving vehicle by using data of acceleration signals extracted only from the accelerometers and metrics calculated from an estimated variation of angle between successive acceleration signals. The method further comprises identifying at least one, short-time or long-time, probe pattern related to the situation of the moving vehicle, the probe pattern using signals and measures exclusively derived from the tri-axial accelerometers, comprising the data of acceleration signals and the calculated metrics. If the situation corresponds to the mobile user terminal moving in the moving vehicle, the geopositioning device is activated.

Abstract: Present disclosure refers to a method for detecting driving events of a vehicle. The method comprises the steps of: obtaining at least one motion data signal from sensors of a mobile device located in the vehicle; sending the at least one motion data signal from the sensors to a processing module; computing, in the processing module, an energy measurement of the at least one motion data signal; selecting time segments where the energy measurement of the at least one motion data signal exceeds a first threshold; analyzing the at least one motion data signal in said time segments; and assigning a driving event to each time segment.
