First Claim
1. A load deflection degree computing apparatus for computing the vehicle deflection degree in a vehicle width direction applied on the vehicle on the basis of outputs from a plurality of weight sensors arranged separately in the vehicle width direction, comprising:
- correction function holding means for holding an output characteristic correction function for correcting the non-linear characteristic of each of said weight sensors into the liner characteristic, said correction function corresponding to the output from each said sensor; and
output characteristic correction means for correcting the output from each said weight sensor in terms of said output characteristic correction function;
wherein said vehicle deflection degree is computed on the basis of the corrected output from each said weight sensor.

Abstract
A carrying weight computing apparatus serves to compute a carrying weight of a vehicle on the basis of the outputs from a plurality of weight sensor arranged apart from each other at least in a vehicle width direction of the vehicle. The carrying weight computing apparatus includes a deflective load setting unit for setting the deflection of load applied to the vehicle, and a carrying weight computing unit for computing the carrying weight on the basis of the deflection of load set by said deflective load setting unit so that the deflection of load and the carrying weight can be computed from the outputs from said weight sensors. The deflective load setting unit includes a correction function holding means for holding an output characteristic correction function corresponding to each said weigh sensor for correcting the non-linear characteristic of each said weight sensor into its linear characteristic, and output characteristic correcting unit for correcting the output from each said weight sensor in terms of the corresponding output characteristic correction function. The deflective load setting unit serves to compute the deflection of load in the vehicle width direction of the load applied to the vehicle on the basis of the corrected outputs from said weight sensors.
