Embodiment Construction
[0022] As shown in the drawing, the device 10 has a weighing sensor device 20 for dynamic force measurement in order to measure the vehicle load of the moving vehicle F, and also has a detection device for determining the vibration state, and has an analysis and processing device 40 For the determined vibration state and the dynamically measured force f dyn Find the static vehicle loads.
[0023] The weighing sensor device 20 is designed as a weighing plate sensor or a piezoelectric sensor embedded in the surface of the road 8, and when the vehicle F drives over them, it measures the action of a single wheel R or a group of wheels passing through the axle of the vehicle F on the scale. The force f on the measuring surface of the heavy sensing device 20 dyn . Dynamic measuring force f dyn has a static force component f sta and the force component f caused by the vibration ω , where the static force component f sta Depends on the self-weight and load of the car F, while th...

The invention relates to a method for executing a method for determining a load of a vehicle (F), in particular wheel load, shaft load and / or total load of the vehicle (F), wherein f applied on the road (S) of at least a wheel (R) of the running vehicle (F) is measured, and the load of the vehicle (F) is calculated with at least a dynamically measured force (f). The method comprises steps of: calculating vibration condition of the vehicle in running with at least a force measuring time, calculating a vibration-caused force part (f) of the force (f) from the vibration condition, and calculating static force part (f) of the force (f) calculated by the force ((f) and the force part (f), calculating the load of the vehicle by at least a static force part (f), thereby accurately calculating the load of the vehicle in running. The invention also relates to a device (10) for carrying out the method.
Description
technical field [0001] The invention relates to a method for determining the load of a moving motor vehicle according to the preamble of claim 1 and a device for carrying out this method according to claim 10 . Background technique [0002] Weighing stations are known for determining the weight of a motor vehicle, which have to be activated additionally by a vehicle to be weighed, the vehicle having to be stopped for the weighing to take place. Such weighing stations are arranged, for example, at the entry or exit of the factory premises in order to determine the load weight of the truck during entry and exit. Weighing stations are also used during traffic inspections, for example to check the proper loading of trucks. [0003] However, the disadvantage of weighing stations is that they can be detected in advance by truck drivers due to their design and can therefore be avoided. They are also more expensive to manufacture and run. Besides that they impede the flow of traf...
