Equipment for use in vehicles and the method of imposing passenger number-dependent charges on vehicles

摘要

The unit (12) has a doppler radar or ultra-wideband (UWS) impulse radar directed onto an interior (15) of a vehicle (2). An evaluation device detects signal patterns in a measurement signal, where the patterns are typical for heart or respiratory activity of an occupant (16). The evaluation device calculates toll data as function of a count value of the patterns and takes the patterns into an account for the count value of the patterns during counting that indicates no speed of the occupant causing a respective signal pattern relative to the unit on an average over observation time. An independent claim is also included for a method for charging an occupant number-dependent toll for vehicles in a road toll system.
