Abstract
Method for controlling weighing of a vehicle travelling on a road by means of a weigh station alongside the road includes determining weight of the vehicle using a processor on-board the vehicle and transmitting from the vehicle using a telematics device, the determined weight of the vehicle to the weigh station. Determining the weight of the vehicle may entail processing inertial property data from an inertial measurement unit (IMU) into an indication of the weight of the vehicle. The inertial property data from the IMU may be multiple sets of inertial property data obtained over time. The IMU may be calibrated, using the processor, based differential motion of the vehicle over a period of time as determined by a location positioning system. A Kalman filter may also be used. A vehicle transmitting its determined weight avoids stopping at the weigh station.
