Title: METHOD FOR OPERATING AN ON-BOARD WEIGHING SYSTEM, AND TACHOGRAPH SYSTEM COMPRISING A WEIGHING SYSTEM
Abstract:
The invention relates to a method for operating an on-board weighing system (101) comprising a sensor (102) for measuring an axle load of a vehicle (100, 119), the method comprising: - determining a voltage curve (103) of an electric operating voltage applied to the sensor, - determining a deviation (105, 106, 107, 108, 109) from a predefined operating voltage (104) and, if the deviation (105, 106, 108) still exists after a predefined period of time (110, 111, 113), - determining a manipulation attempt to manipulate the sensor (102). The invention also relates to a tachograph system comprising a digital tachograph.
