Abstract
A weighing device for determining a center of gravity of a motor vehicle includes at least two weighing elements where a respective measured value characterizing a weight of the motor vehicle is determinable by each of the at least two weighing elements. The respective measured values are receivable from the at least two weighing elements by a computing device and the center of gravity of the motor vehicle is determinable depending on the respective measured values by the computing device. An alignment of the at least two weighing elements relative to one another is adjustable by a displacement device.
Claims9
A weighing device (14) for determining a center of gravity of a trailer of a semitrailer, wherein the semitrailer comprises a semitrailer engine and the trailer, comprising:
- at least two weighing elements (16), wherein a first respective measured value characterizing a weight of the semitrailer engine is determined by each of the at least two weighing elements (16) and wherein a second respective measured value characterizing a weight of the semitrailer comprising the semitrailer engine and the trailer is determined by each of the at least two weighing elements (16);
- a computing device (20), wherein the first respective measured values are received from the at least two weighing elements (16) by the computing device (20) and wherein a center of gravity of the semitrailer engine is determined depending on the first respective measured values by the computing device (20), wherein the second respective measured values are received from the at least two weighing elements (16) by the computing device (20) and wherein a center of gravity of the semitrailer comprising the semitrailer engine and the trailer is determined depending on the second respective measured values by the computing device (20), and wherein the center of gravity of the trailer is determined from the center of gravity of the semitrailer engine and the center of gravity of the semitrailer comprising the semitrailer engine and the trailer by the computing unit (20);
- and
- a displacement device (18), wherein an alignment of the at least two weighing elements (16) relative to one another is adjustable adjusted by the displacement device (18).
A method for determining a center of gravity of a motor vehicle (12), comprising the steps of:
- a) parking the motor vehicle (12) on a weighing device (14) with each axle end of respective axles of the motor vehicle (12) assigned to a respective weighing element (16) of the weighing device (14);
- b) adjusting an alignment of the weighing elements (16) relative to one another by a displacement device (18), wherein the weighing elements (16) are arranged in at least two different alignments relative to one another and wherein a respective measured value characterizing a weight of the motor vehicle (12) is recorded in each of the alignments;
- and
- c) receiving the measured values by a computing device (20) and determining the center of gravity of the motor vehicle (12) on a basis of the measured values;
- wherein the steps a) to c) are respectively carried out for a semitrailer engine and for a semitrailer comprising the semitrailer engine and a trailer and wherein a center of gravity of the trailer is determined from a center of gravity of the semitrailer engine and a center of gravity of the semitrailer by the computing unit (20).
