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.

Abstract: Vehicle weight measuring apparatus and method are provided. In the vehicle weight measuring apparatus, wireless communicable sensors are installed in the leaf spring and frames of the vehicle, and a user receives measured values from the sensors through an electronic device installed in the vehicle or a mobile phone in a wireless manner, so that the weight of vehicle can be measured in real-time and overload vehicle can be prevented. In addition, maintenance can be easily performed in comparison with a conventional method where a strain gauge is connected to the electronic device installed in the vehicle through cables. In addition, inclination sensors (slope sensors) for measuring inclinations of the vehicle and the leaf spring are installed in the vehicle, so that installation and replacement can be easily performed in comparison with the con¬ ventional method where the strain gauge is installed in the vehicle. In addition, a degree of deflection of the leaf spring according to the weight exerted on the vehicle is detected by using the inclination of the leaf spring to measure the weight of the vehicle. Furthermore, the in¬ clination of the leaf spring is measured by taking into consideration the entire inclinations of the vehicle, so that the weight can be accurately measured irrespective of inclination of the site where the vehicle is loaded.
