Vehicle weight observation system
First Claim
1. A weight monitoring system of a motor vehicle, comprising:
- at least one weight sensor, wherein said at least one weight sensor senses at least one weight variable related to the overall weight of a motor vehicle; and
a data processing unit, said data processing unit being operatively coupled with said at least one weight sensor, wherein said data processing unit determines a maximum value for said at least one weight variable based on at least one anticipated operating condition of a planned travel route for the motor vehicle;
wherein said data processing unit compares said at least one weight variable to said maximum value;
wherein said data processing unit generates an alert when said at least one weight variable exceeds said maximum value.

Abstract
The invention relates to a weight monitoring system for a motor vehicle (1) which can, if appropriate, be connected to a trailer (2). The system uses weight sensors to determine the weights (F1, F2) acting on the axles of the motor vehicle, in order to calculate from them the overall weight of the vehicle, and the axle loads. In addition, a tractive force sensor may be provided in the trailer hitch so that the mass of the trailer (2) can be determined by means of the tractive force (F3) and the acceleration of the vehicle. The weight monitoring system calculates various weight variables from the measured values and monitors to determine whether they remain within defined limits. In this context, it is possible, in particular, to take into account a planned route in such a way that the limiting values of the charge are adapted with respect to the maximum altitude (Hmax) above sea level and/or the maximum gradient (smax) of the route. In addition, the system can be configured in such a way that it provides the driver with proposals for a different distribution of the payload which leads to a permissible axle load.
