Abstract
In a linear solenoid, an electromagnetic coil, a pressure sensor, and label resistorsandfor correcting an inherent variation in a pressure detection characteristic are integrated; the standard characteristic of the pressure sensoris stored in a control moduleM; when driving is started, the resistance values of the label resistorsandare read, the pressure detection characteristic of the utilized pressure sensoris corrected, and an excitation current for the electromagnetic coilis controlled in such a way that a target adjusted hydraulic pressure is obtained. Even when due to a change in the oil temperature, the valve opening characteristic of the linear solenoidchanges, the adjusted hydraulic pressure is controlled to be constant.
