Abstract
A method estimating weight of a motor vehicle including front and rear wheel assemblies using a smart communication device after loading the vehicle, including: (i) identifying the vehicle in the smart communication device; (ii) using a camera of the smart communication device, capturing and processing a photograph of at least one vehicle wheel after loading to determine displacement of a corresponding wheel assembly; (iii) using at least one accelerometer or inclinometer of the smart communication device, measuring at least one tilt angle of the vehicle after loading to determine displacement of the opposite wheel assembly and the corresponding wheel assembly; (iv) using a calculation unit of the smart communication device, calculating load values on the corresponding and opposite wheel assemblies based on respective displacements of the wheel assemblies, to determine a total load vehicle value; and (v) indicating by the smart communication device a vehicle load state to the user.
