摘要

Detecting presences inside vehicles of passengers using Smart Personal Communication Devices, in particular smartphones, with regard to a Method, a Digital Tool, the Device, a Gateway and a BIBO-System used therefore In order to detect presences inside vehicles of passengers using Smart Personal Communication Devices, which each enables easily with a minimum of hardware complexity an automated accurate detection of the coupling between a passenger (PAS) using a Smart Personal Communication Device (SPCD) and a vehicle (VEH), it is proposed to (a) execute in a Signal Pre-Processing Step (SPPS) of independently pre-processing at least one passenger-related first sensor signal (SS-1) of the Smart Personal Communication Device and at least one vehicle-related second sensor signal (SS-2) of the vehicle at least a Re-Sampling (RS) and a Magnitude Calculation (MC) to induce signal-specific magnitude values (MV-1, MV-2), (b) apply in a Vehicle Identification Step (VIS) for comparing the signal-specific magnitude values (MV) a "Cross-Correlation Function [CCF]" such that the signal-specific magnitude values are executed in the order of "Overlapping in Time Domain" (OTD), "Windowed Cross-Correlation" (WCC) and Metrification (MEF) to induce due to the Metrification at least one metric-based identification value (IDV) and (c) comparing in the Vehicle Identification Step (VIS) the at least one metrification-based identification value (IDV) each with an overall threshold value (THV) such that, if one of the at least one metrification-based identification value is below or below and equal to the threshold value, a "NO"- statement (N-S) regarding the presence of the passenger in the vehicle is made otherwise a "YES"-statement (Y-S) regarding the presence of the passenger in the vehicle is made.
