In order to rapidly and inexpensively deliver information regarding the load status of a motor vehicle, in particular, a utility vehicle with at least one axle that is suspended on pneumatic springs, there is arranged a sensor for measuring the bellows pressure and one additional sensor for measuring the spring travel on each of the pneumatic springs used in the wheel suspensions of the motor vehicle, and to additionally process the pressure and the spring travel in an electronic control unit. In this case, the spring forces preferably are calculated and displayed first, whereafter the wheel forces and ulitmately the position of the center of gravity, as well as the total weight and/or the weight of the net load, are calculated and displayed. The information regarding the load status preferably is also utilized as an input quantity for other safety systems, e.g., for lowering a lift axle, for issuing a warning and/or for throttling the speed in accordance with the respective requirements. This information can also be evaluated for documenting a motor vehicle load and/or an accident. |
