Apparatus for supporting maintenance check of a sensor

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.
