Onboard unit and method for charging occupant number-dependent tolls for vehicles
First Claim
Patent Images
1. An onboard unit for charging occupant number-dependent tolls for a vehicle in a road toll system, comprising:
- a Doppler radar or ultra-wideband (UWB) impulse radar directed onto the vehicle interior for measuring movements and generating at least one measurement signal representing the movements; and
an evaluation device configured to detect signal patterns in the at least one measurement signal that are typical for heart or respiratory activity of an occupant, to count the signal patterns which occur simultaneously at an observation time, to calculate toll data as a function of a count value of the signal patterns, and to take only those signal patterns into account for the count value of the signal patterns during counting that indicate no speed of the occupant causing the respective signal pattern relative to the onboard unit, on an average over multiple observation times.

Abstract
Onboard unit for charging occupant number-dependent tolls for a vehicle in the context of a road toll system, comprising a Doppler radar or UWB impulse radar that can be directed onto the vehicle interior for measuring movements and generating at least one measurement signal representing these; and an evaluation device, which is configured to detect signal patterns in the measurement signal that are typical for heart or respiratory activity of an occupant, to count those signal patterns which occur simultaneously at an observation time, and to calculate toll data as a function of that count value.

8. A method for charging an occupant number-dependent toll for vehicles in a road toll system, the method comprising:
-
directing a Doppler radar or ultra-wideband (UWB) impulse radar onto an interior of a vehicle to measure movements therein and to generate at least one measurement signal representing the movements; detecting signal patterns in the at least one measurement signal that are typical for heart or respiratory activity of an occupant; counting the signal patterns which occur simultaneously at an observation time by one or more processors, wherein during counting, only signal patterns with an average over multiple observation times indicating no speed of the occupant causing the respective signal pattern relative to the onboard unit are taken into account for the count value of the signal patterns; and calculating toll data as a function of a count value of the signal patterns time by one or more processors. - View Dependent Claims (9, 10, 11, 12, 13)
