Patent ID: 8640553

Claim:
A system for measuring forces applied to a moving vehicle, the system comprising: a sensor plate comprising: a first section configured to couple to a hub of the vehicle; a second section configured to couple to a corresponding wheel of the vehicle; a plurality of measurement arms each coupled between the first and second sections, each measurement arm having a first end, a second end, first side, and a second side; and a plurality of first sets of four strain gauges coupled to a respective one of the plurality of measurement arms, with one strain gauge of each first set attached at each of the first and second sides at each of the first and second ends of the corresponding measurement arm, wherein the strain gauges of corresponding locations on each measurement arm are electrically connected in series to form one of a leg of a Wheatstone bridge; and a lateral force measurement circuit electrically coupled to the Wheatstone bridge and configured to measure a total lateral force between the hub and the wheel and provide an output comprising at least one signal representative of at least a portion of the total lateral force.
