Automatic calibration of on-vehicle weight scales

Abstract

Systems and methods for calibrating an onboard vehicle scale may include disposing a vehicle upon a reference scale; determining reference weight information corresponding to a weight of at least a portion of the vehicle using the reference scale; automatically and wirelessly communicating the reference weight information to an onboard scale coupled to the vehicle; and automatically calibrating the onboard scale using the reference weight information.

What is claimed is: 
     
         1 . A method for calibrating an onboard vehicle scale, the method comprising:
 disposing a vehicle upon a reference scale;   determining reference weight information corresponding to a weight of at least a portion of the vehicle using the reference scale;   automatically and wirelessly communicating the reference weight information to an onboard scale coupled to the vehicle; and   automatically calibrating the onboard scale using the reference weight information.   
     
     
         2 . The method of  claim 1 , wherein automatically calibrating the onboard scale is performed only upon receipt of a request to calibrate the scale. 
     
     
         3 . The method of  claim 1 , further comprising:
 wirelessly requesting the reference weight information from the reference scale using a control system of the onboard scale.   
     
     
         4 . The method of  claim 1 , wherein communicating reference weight information to the onboard scale includes transmitting a unique identifier of the reference scale to a controller of the onboard scale.
