SELF-ADAPTIVE CONTROL METHOD FOR ELIMINATING SENSOR DRIFT AND DEVICE THEREOF

摘要

The invention relates to control of automatic gear box, and in particular it provides the method of adaptive control for eliminating sensor drift. In the method for adaptive control for eliminating sensor drift the adaptive algorithm in its control system compares the signals of oil pressure of the automatic gear box and calculates the value of drift of zero at current temperature of oil. By means of the method at use of the transmission article when the block for control of the gear box operates normally the control system can perform intellectual control of the parameters in online mode and automatically remove the drift of zero of the sensor. The method has high adaptability and makes it possible to keep with requirements to control. The realization of the adaptive algorithm in the control system makes it possible to provide automatic transmission article that maintains optimal characteristics within the whole period of operation, i.e. high safety and low consumed power.
