HOW DOES IT WORK?
HaulGauge measures weight by monitoring powertrain effort and vehicle acceleration. Powertrain effort is calculated from a torque converter model. HaulGauge uses the VIN to search its database for the correct torque converter calibration. If HaulGauge doesn’t find a calibration within its database, the user may calibrate the scale utilizing a patented machine learning algorithm. Acceleration is determined utilizing a triaxial accelerometer on board HaulGauge. When powertrain effort is high relative to vehicle acceleration, then weight has increased.
