ABSTRACT:
The mass of a vehicle is determined by recognizing that the natural oscillations in the transmission line of a motor vehicle and the mass of the motor vehicle are in a one-to-one relationship if the instantaneous transmission ratio remains unchanged. To determine the natural oscillations, i.e., the rate of fluctuations, a computer records engine speed signals of a speed transducer and calculates therefrom the actual vehicle mass, taking into account the instantaneous transmission ratio, which can be determined for example by comparing the engine speed to the vehicle speed or sensing the engaged gear of the gear box.
