DETERMINATION OF ACTIVITY RATE OF PORTABLE ELECTRONIC EQUIPMENT

摘要

A method for obtaining activity rate of a portable electronic device (250) during travel with a vehicle (200) comprises determining (S100) a calculated driving distance based on the portable electronic device utilizing a sequence of measured positions for the portable electronic device. The method further comprises determining (S200) a read driving distance by reading of odometer indication (270) of the vehicle. The method also comprises calculating (S300) an activity rate by comparison of the calculated driving distance with the read driving distance. The method further comprises calculating (S400) a flag which indicates the validity of the calculated activity rate, where the flag is calculated based on the sequence of measured positions for the portable electronic device. The method also comprises transferring (S500) an information packet (280) to a central server (290), where the information packet comprises the activity rate, and/or the read driving distance, and/or the flag.
