Axial weight measuring device, measurement accuracy diagnosis method and measurement accuracy diagnosis program

摘要

Problem: it is possible to determine whether the measurement accuracy of the shaft weight sensor arranged in the traveling direction of the vehicle is appropriate irrespective of whether or not the vehicle is running or not.A measuring signal of a plurality of axial load sensors 2 to 4 arranged in the traveling direction of the vehicle 100 is input to the axial force sensor connecting portion 12.A measurement value DB 14 collects a measurement value corresponding to the input measurement signal for each of the axial load sensors 2 to 4.The aggregated portion 23 collects the collected measurement values for each of the axial load sensors 2 to 4 and acquires the totaling result.If the discrepancy between the two axes of gravity sensors 2 to 4 is within an appropriate range, the decision unit 25 determines that the accuracy of the axial force sensor is appropriate.Diagram
