método e dispositivo de controle adaptativo para eliminar desvio do sensor

摘要

A self-adaptive control method for eliminating sensor drift, involves: reading one-dimensional table data representing the relationship between an oil temperature and a sensor zero drift value with a self-adaptive control system of an automatic gearbox control unit; collecting signals for self-adaptive control with a single chip microcomputer analog/digital module of the automatic gearbox control unit; judging the running condition of a self-adaptive algorithm by a program. By inquiring the one-dimensional table data, the sensor zero drift value is generated by the self-adaptive algorithm.
