System and method for measuring load applied to a vehicle axle, method for calibrating the system, and sensing device
PCT designated stageWO2026020223A1Weighing temperature-compensating arrangementsSpecial purpose weighing apparatusDriver/operatorVehicle driving
The present invention relates to a system for measuring load applied to a vehicle axle, a method for measuring load applied to a vehicle axle, a method for calibrating the measuring system, and a device for sensing axle strain. The present invention specifically comprises a solution capable of measuring the load applied to vehicle axles and to the whole vehicle by reading the strain caused to the vehicle axle as a function of forces generated by the loading of the vehicle. The strain-reading device is arranged in an optimised structure that is easy to mount on the vehicle and is configured to prevent interference in the reading of collected data, contributing to improved load measurement. The strain or load values for each axle are sent to a cloud platform, processed and made available to the vehicle driver and / or transport company, so that they can visualise and monitor the weight and distribute the load across the axles according to the measured values. The present invention pertains to the fields of mechanical engineering and measuring systems intended for commercial vehicles.
