Title:
LOAD MEASURING DEVICE AND METHOD OF WEIGHING VEHICLE HAVING SUSPENSION WITH TWO-STAGE SPRINGS
Document Type and Number:
WIPO Patent Application WO/2012/053869
Kind Code:
A2
Abstract:
The present invention provides a load measuring device and method capable of measuring, in real time, the load of a vehicle having a suspension with two-stage springs. The invention allows: sensors to be installed in both main springs and auxiliary springs of the suspension which has two-stages; and the weight, which is applied to the vehicle, to be measured by using measurement values of the sensors installed in the main springs and measurement values of the sensors installed in the auxiliary springs, wherein the measurement values are changed as the load is applied to the vehicle. Particularly, the invention adopts; a load measuring method using sensor values of the main springs or sensor values of the auxiliary springs in each load section of the vehicle; or a method for measuring the load that is applied to the vehicle by adding up the sensor measurement values of the main springs and the sensor measurement values of the auxiliary springs such that a mathematical formula capable of changing the added measurement values into the load is modeled, thereby calculating the applied load in real time by using the measurement values of the sensors, which are changed in real time according to the load that is applied to the vehicle, and outputting the calculated load to a user.
Thus, even for conventional vehicles having a suspension with two-stage springs, to which the method for measuring the load of the vehicle in real time is difficult to apply, the invention can measure the exact load of the vehicle in real time, thereby effectively preventing an overload.
