WEIGHT SELF-CALIBRATION FOR HEAVY-DUTY VEHICLE OR MACHINE

Patentradars sammanfattning

The invention is a computer system and method for autonomous weight self-calibration of heavy-duty vehicles or vehicle combinations (trucks, buses, trailers, construction equipment). During normal driving, processing circuitry continuously performs dynamic gross weight/mass estimation (e.g. via Newton's second law, Kalman filters, or energy-based methods), computes the estimation uncertainty, and—only when uncertainty falls below a configurable threshold—uses the estimate to recalibrate the suspension system's load sensing functionality (pressure sensors in air/hydraulic bellows or deflection/level sensors in spring suspensions). The approach eliminates or significantly reduces the need for periodic weighbridge visits, addresses sensor drift and spring sag over vehicle lifetime, and supports multi-point calibration across different load conditions for improved accuracy.
