METHOD AND SYSTEM FOR INCREASING ACCURACY OF WEIGHING MOTOR VEHICLE IN MOTION Russian patent published in 2012 - IPC G01G19/03 

FIELD: physics.

SUBSTANCE: weighing devices are placed on a track for wheel-by-wheel or axle-by-axle weighing of a motor vehicle, where readings of one of the devices, having a higher accuracy, is considered the reference reading. A reading device is placed near each of the weighing devices to read the identification mark of a passing motor vehicle. Readings from a weighing device are received at a data processing centre when the wheels or wheel of each of the axles of a specific motor vehicle passes said device, with simultaneous reading of the identification mark of the motor vehicle and recording of the reading time. Series of measurements are formed at the data processing centre from the readings of the weighing devices separately for each wheel or for each axle of the motor vehicle with the same identification mark. Those series of measurements in which deviation of readings of the weighing devices from the corresponding reference reading is less than a predetermined threshold are selected and readings of the weighing devices making up said series of measurements are equated to the corresponding reference reading.

EFFECT: high measurement accuracy of all weight sensors installed on the track, as well as independently from change in weight of a motor vehicle.
