Title:
変速機制御装置、および変速機制御装置の出力特性調整方法
Document Type and Number:
Japanese Patent JP5496259
Kind Code:
B2
Abstract:
In a linear solenoid 107n, an electromagnetic coil 71n, a pressure sensor 72n, and label resistors 73n and 74n for correcting an inherent variation in a pressure detection characteristic are integrated; the standard characteristic of the pressure sensor 72n is stored in a control module 120M; when driving is started, the resistance values of the label resistors 73n and 74n are read, the pressure detection characteristic of the utilized pressure sensor 72n is corrected, and an excitation current for the electromagnetic coil 71n is 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 solenoid 107n changes, the adjusted hydraulic pressure is controlled to be constant.
