Apparatus for supporting maintenance check of a sensor
First Claim
1. An apparatus for supporting maintenance check of a sensor, said sensor generating a changeable weight signal in accordance with a load imposed on a vehicle, comprising:
- storing means for storing information of judging degradation of sensing accuracy of said sensor;
fetching means for fetching the weight signal generated by said sensor;
judging means for judging whether or not sensed accuracy of a present weight signal generated by said sensor is degraded based on a compared result obtained by comparing said present weight signal fetched by said fetching means with a previous weight signal fetched from said sensor that corresponds to said present weight signal and said information of judging degradation stored by said storing means;
maintenance check information generating means to press for maintenance check of said sensor based on the judged degradation thereof in accordance with judgement of degradation by said judging means; and
output means for outputting information of maintenance check generated by said generating means to press for said maintenance check.

Abstract
An apparatus for supporting maintenance check of a sensor to maintain sensing accuracy, the sensor 10 generating a changeable weight signal in accordance with a load imposed on a vehicle, includes judging means 30a2 for judging whether or not sensed accuracy of a present weight signal is degraded based on a compared result by comparing the present weight signal fetched by a fetching means 30a1 with a previous weight signal from the sensor that corresponds to the present weight signal and information of judging degradation stored by a storing means 30d, and maintenance check information generating means 30a3 to press for maintenance check of the sensor based on the judged degradation in accordance with judgement of degradation by the judging means 30a2.
