Title:
リニアソレノイドバルブの制御装置
Document Type and Number:
Japanese Patent JP7381199
Kind Code:
B2
Abstract:
A control apparatus for a linear solenoid valve configured to regulate a hydraulic pressure in a vehicle transmission. The control apparatus includes a hydraulic control portion configured to output a control command signal that is applied to a solenoid of the linear solenoid valve. The hydraulic control portion outputs, as the control command signal, a regulating control command signal by which the hydraulic pressure is to be regulated to a regulated pressure value that is dependent on a vehicle driving state. When the regulated pressure value is in a certain pressure range in which vibration-based noise is likely to be generated by vibration of the linear solenoid valve that is operated with the regulating control command signal being applied to the solenoid, the hydraulic control portion outputs, as the control command signal, a noise-restraining command signal by which generation of the vibration-based noise is restrained.
