METHOD AND APPARATUS FOR LEARNING LINEARITY ERROR OF HYDRAULIC PRESSURE SENSOR FOR HYDRAULIC CLUTCH

摘要

A method and an apparatus for learning linearity error of a hydraulic pressure sensor for a hydraulic clutch are disclosed. An apparatus for learning linearity error of a hydraulic pressure sensor for a hydraulic clutch may include: a gear stage sensor detecting a gear stage that is currently engaged; a controller executed by a predetermined program to learn the linearity error of the hydraulic pressure sensor based on signals of the gear stage sensor and the hydraulic pressure sensor; and a solenoid valve applying hydraulic pressure for learning the linearity error of the hydraulic pressure sensor to the hydraulic clutch based on a learning command of the controller.
